Transmitter is 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 protected Jeweller protocol to the hub. It is not intended to use the device in third-party systems.
Not compatible with the uartBridge or ocBridge Plus
The communication range can be up to 1,600 meters provided that there are no obstacles and the case is removed.
Transmitter is set up via a mobile application for iOS and Android based smartphones.
Functional Elements
- QR code with the device registration key.
- Batteries contacts.
- LED indicator.
- ON/OFF button.
- Terminals for detector power supply, alarm, and tamper signals.
Operation procedure
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 manage Night 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.

Connecting to the hub
The hub and the device operating at different radio frequencies are incompatible. The radio-frequency range of the device may vary by region. We recommend purchasing and using Ajax devices in the same region. You can check the range of operating radio frequencies with the technical support service.
Before starting connection
- Following the hub instruction recommendations, install the Ajax application on your smartphone. Create an account, add the hub to the application, and create at least one room.
- Go to the Ajax application.
- Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
- Ensure that the hub is disarmed and does not start updates by checking its status in the mobile application.
Only users with administrative privileges can add the device to the hub
How to connect Transmitter to the hub
- Select the Add Device option in the Ajax application.
- Name the device, scan or enter manually the QR code (located on the body and packaging), and select the location room.
- Select Add — the countdown will begin.
- Switch on the device (by pressing on/off button for 3 seconds).
For the detection and interfacing to occur, the device should be located within the coverage area of the wireless network of the hub (at a single protected object).
Request for connection to the hub is transmitted for a short time at the time of switching on the device.
If the connection to the Ajax hub failed, Transmitter will switch off after 6 seconds. You may repeat the connection attempt then.
Transmitter connected to the hub will appear in the list of devices of the hub in the application. Update of device statuses in the list depends on the device inquiry time set in the hub settings, with the default value – 36 seconds.

How to set Chime
Chime is a sound signal that indicates the triggering of the opening detectors when the system is disarmed. The feature is used, for example, in stores, to notify employees that someone has entered the building.
Notifications are configured in two stages: setting up opening detectors and setting up sirens.
Transmitter settings
Before setting up the Chime feature, make sure that a wired opening detector is connected to Transmitter and the following options have been configured in the detector settings in the Ajax app:
- Detector power supply
- External Detector Contact Status
- External Detector Type
- Type of event
- Tamper status
- Go to the Devices menu.
- Select Transmitter.
- Go to its settings by clicking the gear icon in the upper right corner.
- Go to the Chime Settings menu.
- Select siren notification for the event If external contact is open.
- Select the chime sound: 1 to 4 beeps. Once selected, the Ajax app will play the sound.
- Click Back to save the settings.
- Set up the required siren.
Indication
| Event | Indication |
| The Module is switched on and registered | The LED lights up when the ON button is briefly pressed. |
| Registration failed | The LED blinks for 4 seconds with an interval of 1 second, then blinks 3 times rapidly (and automatically switches OFF). |
| The Module is deleted from the list of hub devices | The LED blinks for 1 minute with an interval of 1 second, then blinks 3 times rapidly (and automatically switches OFF). |
| The Module has received alarm/tamper signal | The LED lights up for 1 second. |
| Batteries are discharged | Smoothly lights up and goes out when the detector or tamper is activated. |
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 on Jeweller settings in hub settings).
Connection of the Module to the wired detector
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.
If after moving, the device still has a low or unstable signal strength, use a radio signal range extender.
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 AWG twisted pair). The value may vary when using different type of cable.
The function of the terminals of Transmitter
- “+ —” — power terminals of the connected wired device, the output voltage is 3.3 V⎓.
- ALARM — alarm terminals of the device.
- TAMP — terminals of the device tamper.
Do not connect a third-party power supply unit to the power terminals. This may damage the device
-
Secure Transmitter in the casing. Plastic bars are included in the installation kit. It is recommended to install Transmitter on them.
Do not install Transmitter:
- Near metal objects and mirrors (they can shield the radio signal and lead to its attenuation).
- Closer than 1 meter to a hub.
Maintenance and Battery Replacement
The device does not require maintenance when mounted in the housing of a wired sensor.
