Transmitter is a module for connecting third-party detectors to Ajax security system. It transmits alarms and warns about the activation of the external detector tamper and it is equipped with own accelerometer, which protects it from dismounting. It runs on batteries and can supply power to the connected detector.
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.
The Ajax security system is self-sustaining, but the user can connect it to the central monitoring station of a security company.

- Batteries contacts.
- LED indicator.
- ON/OFF button.
- Terminals for detector power supply, alarm and tamper signals.
The Transmitter serves for connecting the external alarm sources to Ajax system: indoor and outdoor detectors tracking motion, opening, vibrations, breaks, fire, gas, leakage, etc. Compatible with detectors with NC/NO contacts.
Transmitter receives information about alarms and the activation of the external detector tamper button through the terminals. A separate pair of terminals ensures power supply to the external detector from the module batteries with 3.3 V.
Connecting to the hub
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 the Transmitter to the hub:
- Select the Add Device option in the Ajax application.
- Name the device, scan/write 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, the Transmitter will switch off after 6 seconds. You may repeat the connection attempt then.
The 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.

Set the following parameters in the Transmitter settings:
- The state of the external detector contact, which can be normally closed or normally open.
- The type (mode) of the external detector that can be bistable or pulse.
- The tamper mode, which can be normally closed or normally open.
- The accelerometer-triggered alarm — you can turn this signal off or on.
Select the power mode for the external detector:
- Turned off when the hub is disarmed — the module stops powering the external detector upon disarming and does not process signals from the ALARM terminal. When arming the detector, the power supply resumes, but the alarm signals are ignored for the first 8 seconds.
- Always disabled — the Transmitter saves energy by turning off the power of the external detector. The signals from the ALARM terminal are processed both in the pulse and bistable modes.
- Always active — this mode should be used if there are any problems in the “Turned off when the hub is disarmed”. When the security system is armed, signals from the ALARM terminal are processed no more than once in three minutes in the pulse mode. If the bistable mode is selected, such signals are processed instantly.
If the “Always active” operating mode is selected for the module, the external detector is powered only in the “Always active” or the “Turned off when the hub disarmed” mode, regardless of the security system status.
|The Module is switched on and registered||The LED lights up when the ON button is briefly pressed.|
|Registration failed||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||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.|
The Ajax security 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 detectorа
Location of the Transmitter 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! As a minimum, move the device – even 20 cm shift can significantly improve the quality of reception.
If, after moving, the device still has a low or unstable signal strength, use a radio signal range extender ReX.
The Transmitter should be encased inside the wired detector case. The Module requires a space with the following minimum dimensions: 110 х 41 х 24 mm. If the installation of the Transmitter within the detector case is impossible, then any available radiotransparent case could be used.
- Connect the Transmitter to the detector through the NC/NO contacts (choose the relevant setting in the application) and COM.
The maximum cable length for connecting the sensor is 150 m (24 AWG twisted pair). The value may vary when using different type of cable.
The function of the Transmitter’s terminals
2. Secure the Transmitter in the case. Plastic bars are included in the installation kit. It is recommendable to install the Transmitter on them.
