Transmitter User manual
Updated
Transmitteris a module for connecting third-party detectors to Ajax security system. It transmits alarms and notifies when the tamper of the third-party detector triggers. The module is equipped with its own accelerometer, which protects it from dismounting. It runs on batteries and can supply power to the connected detector.
Transmitter operates within the Ajax security system, by connecting via the protectedJewellerprotocol to thehub. It is not intended to use the device in third-party systems.
Terminals for detector power supply, alarm, and tamper signals.
Operation procedure
The transmitter is designed to connect third-party wired sensors and devices to the Ajax security system. The integration module receives information about alarms and tamper activation through the wires connected to the clamps.
Transmitter can be used to connect panic and auxiliary request buttons, indoor and outdoor motion detectors, as well as opening, vibration, breaking, fire, gas, leakage, and others wired detectors.
Also, you can set up KeyArm Zone that allows switching system arming modes with a third-party device connected to Transmitter. KeyArm allows you to arm/disarm the system, individual groups, or manageNight Mode.
The KeyArm feature is supported by all hubs (except Hub model) with OS Malevich 2.17 and higher.
The type of alarm is indicated in the settings of Transmitter. The text of notifications about alarms and events of the connected device, as well as event codes transmitted to the central monitoring panel of the security company (CMS) depend on the selected type.

Performance testing
The Ajax system allows conducting tests for checking the functionality of connected devices.
The tests do not start straight away, but within a period of 36 seconds when using the standard settings. The test time start depends on the settings of the detector scanning period (the paragraph onJewellersettings in hub settings).
Transmitter location determines its remoteness from the hub and presence of any obstacles between the devices hindering the radio signal transmission: walls, inserted floors, large-size objects located within the room.
Check the signal strength level at the installation location
If the signal level is one division, we cannot guarantee stable operation of the security system. Take possible measures to improve the quality of the signal. At least, move the device with an integration module - even a 20 cm shift can significantly improve the signal strength.
Transmitter should be installed inside the wired detector case. The module requires a space with the following minimum dimensions: 110 × 41 × 24 mm. If the installation of Transmitter within the detector case is impossible, then any available radiotransparent case could be used.
Connect Transmitter to the detector through the NC/NO contacts (choose the relevant setting in the app) and COM.
The maximum cable length for connecting the sensor is 130 m (24 AWGtwisted pair). The value may vary when using different type of cable.

Operating principle
vhfBridge Jeweller is designed to connect third-party VHF transmitters to create an additional channel for transmitting events to the CMS.
The communication channel with the CMS created using vhfBridge Jeweller can be used as the only or as a backup channel for communicating with the CMS (recommended more reliable option). This means that the hub can simultaneously transmit all events and alarms to the monitoring station of the security company not only through SIA (DC-09), ADEMCO 685, SurGard (Contact ID), and other proprietary protocols but also using vhfBridge Jeweller.
The transponder receives information about alarms and events from the hub via the Jeweller radio channel. Then, vhfBridge Jeweller transmits it to a third-party VHF transmitter via wires. The VHF transmitter, in turn, transmits all events and alarms to the CMS via a radio channel.
Events can be transmitted to the CMS via the Internet and vhfBridge Jeweller in parallel. Transmission via the Internet works as the main channel because of greater reliability and informativity. The transmitted events may contain the zone number of the triggered detector, group number, user number, and other data.
vhfBridge Jeweller works as a backup communication channel duplicating all events transmitted via the Internet. The delivery speed of events and alarms in both cases does not exceed 1 second.
An example of the algorithm of actions in case of an alarm from a MotionProtect motion detector:
MotionProtect has detected an alarm.
MotionProtect transmits the alarm to the hub via the Jeweller radio protocol.
The hub receives the MotionProtect alarm and transmits it to vhfBridge Jeweller via the Jeweller radio protocol.
The vhfBridge Jeweller receives the alarm from the hub and transmits it to the VHF transmitter over a wired connection.
The VHF transmitter receives the alarm and transmits it to the radio receiver on the CMS side via the radio channel.
The radio receiver receives the alarm and transmits it to the CMS software.
The CMS receives and processes the alarm.
Output types
vhfBridge Jeweller has 8 potential outputs for connection to a VHF transmitter. There are two types of outputs:
High potential output (positive trip).
Low potential output (negative trip).
The high-potential output does not supply voltage in the normal state. As soon as an alarm or event occurs, the output supplies a voltage of 12-14 V⎓. The low-potential output works the other way around. In the normal state, the voltage is maintained at 12-14 V⎓, and when an alarm or event occurs, it drops to 0 V.
The vhfBridge Jeweller output type and alarm pulse duration are configurable in Ajax apps.
VHF transmitter power supply
The vhfBridge Jeweller can supply a third-party VHF transmitter with 12 V⎓ power (maximum output current is 2 A).
If the VHF transmitter has a current consumption of more than 2 A, it can be powered by the vhfBridge Jeweller battery. In this case, disable battery charge tracking in the vhfBridge Jeweller settings so that the system users do not receive notifications about the vhfBridge Jeweller battery charging too long.
Sending events to the Central Monitoring Station (CMS)
The Ajax security system can transmit alarms to thePRO Desktopmonitoring app as well as the Central Monitoring Station (CMS) usingSurGard (Contact ID),SIA DC-09 (ADM-CID),ADEMCO685, and other proprietary protocols. The list of supported protocols isavailable here.
When an alarm is received, the monitoring station operator of the security company knows what happened and where the rapid response unit has to be sent. All Ajax devices are addressable, so events, the device type, its assigned name and room can be transmitted to the PRO Desktop and the CMS. The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.
You can find vhfBridge Jeweller ID and zone number in the Statesin Ajax apps. The device number corresponds to the loop (zone) number.

How to connect a VHF transmitter to vhfBridge Jeweller
When connecting the VHF transmitter, do not twist the wires together, but solder them. The ends of the VHF transmitter wires, which will be inserted into the vhfBridge Jeweller terminals should be tinned or crimped with a special sleeve.
Turn off the vhfBridge Jeweller power (if power was connected).
Turn off vhfBridge Jeweller.
Select vhfBridge Jeweller outputs to which you want to connect the VHF transmitter.
Pull the VHF transmitter wires into the vhfBridge Jeweller casingthrough the holes.
There are perforated sections on the casing that can be broken off so that the cable could be pulled through them.
Connect the VHF transmitter to the control outputs of vhfBridge Jeweller according to the wiring diagram in the User Guide supplied by the VHF transmitter manufacturer.
Fasten the cable securely to the vhfBridge Jeweller terminals using a straight screwdriver (slot PL 3.0).
Connect the power to the VHF transmitter.
If a VHF transmitter requires 12 V power to operate, it can be connected to the power terminals of the corresponding vhfBridge Jeweller zone. Do not connect the external power supply to the transmitter power terminals, as this may damage the device.
Connect power to vhfBridge Jeweller.
Turn on vhfBridge Jeweller.
vhfBridge Jeweller functionality testing
Integration module functionality tests do not start immediately but not later than over a single "hub - detector" polling interval (36 seconds with standard hub settings). You can change the polling period of devices in the Jeweller menu of the hub settings.
The placement of vhfBridge Jeweller determines its distance from the hub and the presence of obstacles between them that impede the passage of the radio signal: walls, inter-floor constructions, or large-sized objects located in the room.
Be sure to check the signal strength at the installation site. If the signal strength is low (a single bar), we cannot guarantee a stable operation of the security system. At the very least, relocate the device as repositioning even by 20 cm can significantly improve signal reception.
If poor or unstable signal strength is still reported after the relocation of the device, use the radio signal range extender.
When choosing the installation location, consider the distance between vhfBridge Jeweller and the VHF transmitter: the cable length should be sufficient for connection.
The minimum distance between vhfBridge Jeweller and the radio transmitter is 2 meters and the maximum distance is 7 meters. The minimum distance is required to avoid signal overlapping. The maximum distance allowed will help avoid signal attenuation in the cable.
Material and cross-section of the cable for connecting a VHF transmitter are determined by the manufacturer's requirements and the maximum current. All requirements can be found in the manual or from the customer service of the VHF transmitter manufacturer.
vhfBridge Jeweller installation
Prior to mounting vhfBridge Jeweller, ensure that you have selected the optimal location corresponding to these instructions.
The transponder casing should be mounted on a vertical surface. If installed on a horizontal surface, thetamperwill not work when somebody attempts to dismantle the transponder.
To install vhfBridge Jeweller:
Remove the vhfBridge Jeweller casing lid by unscrewing the bottom and top screws with the bundled hex wrench.
Remove the vhfBridge Jeweller board from the holders by pulling them to the sides.
Prepare cable openings in advance by carefully breaking out the perforated parts of the casing.
Fasten the casing to a vertical surface at the chosen installation location using the bundled screws. When attaching, use all the fixation points on the casing. One of them, in the perforated part of the mount above the tamper, is needed to trigger the tamper on the back of the board in case of an attempt to tear the casing off the surface.
Run the cables into the transponder casing through the previously made holes.
Install the vhfBridge Jeweller board into the casing on the racks.
Secure the cable with cable ties using special mounts inside the casing.
Install a 12 V⎓ backup battery on the special holders in the casing. Please note that vhfBridge Jeweller cannot be connected to third-party power supply units.
We recommend using a 12 V⎓ battery of 4 or 7 Ah. For such batteries, special holders in the casing are designed. You can also use similar batteries of a different capacity, of the matching size, and with a charging time of no more than 30 hours. The maximum dimensions of the battery to be installed in the casing are 150 × 65 × 94 mm, and the weight is 5 kg.
Connect a backup battery to the board terminals according to the wiring diagram below (use the bundled cable). Follow the polarity and connection order of the wires. Securely fasten the conductors to the terminals.
Install the lid on the casing and fix it with the bundled screws.
Test vhfBridge Jeweller and connected VHF transmitter.
Do not install vhfBridge Jeweller
Outdoors. Doing so may cause the device to malfunction or not work properly.
Near metal objects or mirrors (for example, in a metal cabinet). They can shield and attenuate the radio signal.
Inside premises with temperature and humidity outside the permissible limits. Doing so may cause the device to malfunction or not work properly.
At a distance less than 1 meter from the hub or range extender. This could result in the loss of connection with the hub.
At a distance less than 2 meters from the VHF transmitter. The minimum distance is required to avoid signal overlapping
At a distance more than 7 meters from the VHF transmitter. The maximum distance allowed will help avoid signal attenuation in the cable.
Maintenance
Check the functionality of vhfBridge Jeweller regularly. The optimal frequency of checks is once every three months. Clean the casing from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care. Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to clean the device.

Operating principle
vhfBridge Jeweller is designed to connect third-party VHF transmitters to create an additional channel for transmitting events to the CMS.
The communication channel with the CMS created using vhfBridge Jeweller can be used as the only or as a backup channel for communicating with the CMS (recommended more reliable option). This means that the hub can simultaneously transmit all events and alarms to the monitoring station of the security company not only through SIA (DC-09), ADEMCO 685, SurGard (Contact ID), and other proprietary protocols but also using vhfBridge Jeweller.
The transponder receives information about alarms and events from the hub via the Jeweller radio channel. Then, vhfBridge Jeweller transmits it to a third-party VHF transmitter via wires. The VHF transmitter, in turn, transmits all events and alarms to the CMS via a radio channel.
Events can be transmitted to the CMS via the Internet and vhfBridge Jeweller in parallel. Transmission via the Internet works as the main channel because of greater reliability and informativity. The transmitted events may contain the zone number of the triggered detector, group number, user number, and other data.
vhfBridge Jeweller works as a backup communication channel duplicating all events transmitted via the Internet. The delivery speed of events and alarms in both cases does not exceed 1 second.
An example of the algorithm of actions in case of an alarm from a MotionProtect motion detector:
MotionProtect has detected an alarm.
MotionProtect transmits the alarm to the hub via the Jeweller radio protocol.
The hub receives the MotionProtect alarm and transmits it to vhfBridge Jeweller via the Jeweller radio protocol.
The vhfBridge Jeweller receives the alarm from the hub and transmits it to the VHF transmitter over a wired connection.
The VHF transmitter receives the alarm and transmits it to the radio receiver on the CMS side via the radio channel.
The radio receiver receives the alarm and transmits it to the CMS software.
The CMS receives and processes the alarm.
Output types
vhfBridge Jeweller has 8 potential outputs for connection to a VHF transmitter. There are two types of outputs:
High potential output (positive trip).
Low potential output (negative trip).
The high-potential output does not supply voltage in the normal state. As soon as an alarm or event occurs, the output supplies a voltage of 12-14 V⎓. The low-potential output works the other way around. In the normal state, the voltage is maintained at 12-14 V⎓, and when an alarm or event occurs, it drops to 0 V.
The vhfBridge Jeweller output type and alarm pulse duration are configurable in Ajax apps.
VHF transmitter power supply
The vhfBridge Jeweller can supply a third-party VHF transmitter with 12 V⎓ power (maximum output current is 2 A).
If the VHF transmitter has a current consumption of more than 2 A, it can be powered by the vhfBridge Jeweller battery. In this case, disable battery charge tracking in the vhfBridge Jeweller settings so that the system users do not receive notifications about the vhfBridge Jeweller battery charging too long.
Sending events to the Central Monitoring Station (CMS)
The Ajax security system can transmit alarms to thePRO Desktopmonitoring app as well as the Central Monitoring Station (CMS) usingSurGard (Contact ID),SIA DC-09 (ADM-CID),ADEMCO685, and other proprietary protocols. The list of supported protocols isavailable here.
When an alarm is received, the monitoring station operator of the security company knows what happened and where the rapid response unit has to be sent. All Ajax devices are addressable, so events, the device type, its assigned name and room can be transmitted to the PRO Desktop and the CMS. The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.
You can find vhfBridge Jeweller ID and zone number in the Statesin Ajax apps. The device number corresponds to the loop (zone) number.

Connect power to vhfBridge Jeweller.
Turn on vhfBridge Jeweller.
vhfBridge Jeweller functionality testing
Integration module functionality tests do not start immediately but not later than over a single "hub - detector" polling interval (36 seconds with standard hub settings). You can change the polling period of devices in the Jeweller menu of the hub settings.
The placement of vhfBridge Jeweller determines its distance from the hub and the presence of obstacles between them that impede the passage of the radio signal: walls, inter-floor constructions, or large-sized objects located in the room.
Be sure to check the signal strength at the installation site. If the signal strength is low (a single bar), we cannot guarantee a stable operation of the security system. At the very least, relocate the device as repositioning even by 20 cm can significantly improve signal reception.
If poor or unstable signal strength is still reported after the relocation of the device, use the radio signal range extender.
When choosing the installation location, consider the distance between vhfBridge Jeweller and the VHF transmitter: the cable length should be sufficient for connection.
The minimum distance between vhfBridge Jeweller and the radio transmitter is 2 meters and the maximum distance is 7 meters. The minimum distance is required to avoid signal overlapping. The maximum distance allowed will help avoid signal attenuation in the cable.
Material and cross-section of the cable for connecting a VHF transmitter are determined by the manufacturer's requirements and the maximum current. All requirements can be found in the manual or from the customer service of the VHF transmitter manufacturer.

Install the vhfBridge Jeweller board into the casing on the racks.
Secure the cable with cable ties using special mounts inside the casing.
Install a 12 V⎓ backup battery on the special holders in the casing. Please note that vhfBridge Jeweller cannot be connected to third-party power supply units.
We recommend using a 12 V⎓ battery of 4 or 7 Ah. For such batteries, special holders in the casing are designed. You can also use similar batteries of a different capacity, of the matching size, and with a charging time of no more than 30 hours. The maximum dimensions of the battery to be installed in the casing are 150 × 65 × 94 mm, and the weight is 5 kg.
Connect a backup battery to the board terminals according to the wiring diagram below (use the bundled cable). Follow the polarity and connection order of the wires. Securely fasten the conductors to the terminals.
Install the lid on the casing and fix it with the bundled screws.
Test vhfBridge Jeweller and connected VHF transmitter.
Do not install vhfBridge Jeweller
Outdoors. Doing so may cause the device to malfunction or not work properly.
Near metal objects or mirrors (for example, in a metal cabinet). They can shield and attenuate the radio signal.
Inside premises with temperature and humidity outside the permissible limits. Doing so may cause the device to malfunction or not work properly.
At a distance less than 1 meter from the hub or range extender. This could result in the loss of connection with the hub.
At a distance less than 2 meters from the VHF transmitter. The minimum distance is required to avoid signal overlapping
At a distance more than 7 meters from the VHF transmitter. The maximum distance allowed will help avoid signal attenuation in the cable.
Maintenance
Check the functionality of vhfBridge Jeweller regularly. The optimal frequency of checks is once every three months. Clean the casing from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care. Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to clean the device.

A compatible Ajax hub is required for the antenna to work.
The device is compatible with:
Hub BP Jeweller
ExternalAntenna sold separately.
Operating principle
ExternalAntenna improves communication between the hub and connected devices or mobile network. It is useful when the Hub is installed in a safe, in a reinforced concrete room or in other places where the signal has to overcome obstacles. The antenna can be connected to the required Jeweller, Wings or Cellular connectors.
Choosing the installation location
When selecting the installation location for the antenna, factors affecting its performance must be taken into account:
Signal strength of the selected communication channel (Jeweller, Wings or Cellular).
Distance between the antenna and the hub. When using two or more antennas, the distance between them must be at least 60 cm.
Obstacles affecting the radio signal: walls, ceilings and large objects in the room.
Follow the installation recommendations when designing your Ajax system. The safety system must only be designed and installed by specialists. A list of recommended Ajax partners is available here.
Places where the antenna should not be installed
In rooms where the temperature and humidity exceed the permissible limits. This can damage the antenna.
In areas with low signal levels. This may cause loss of connection.
Close to metal objects and mirrors. Conductive objects may obscure the antenna.
Preparing for installation
Before installing the external antenna, make sure that:
The hub is compatible with the ExternalAntenna;
the hub has a stable 2-3 bar signal with the mobile network at the installation site;
all connected devices have a stable 2-3 bar signal at the installation site;
the cable length from the hub to the installation site is sufficient.
Cable layout
When preparing the cable routing, check the wiring and fire safety regulations for your region. Strictly comply with these standards and regulations. Practical advice on cable routing is available in this article.
