Ajax Transmitter
The Ajax Transmitter is a wireless integration module that allows you to connect any third-party wired sensors (e.g. motion sensors, IR barriers, gas, water or leak detectors, fire or smoke detectors, temperature or level sensors, etc.) to your Ajax alarm system.
The module receives the sensor signal (alarm or tamper) via the wires and transmits it as a wireless signal to the Ajax centre. If required, the transmitter can also supply power to the connected sensor.
The transmitter also makes “old” wired devices fully compatible with the Ajax system – setting levels are displayed in the Ajax application like normal Ajax devices and alarms, tamper notifications, etc. work in the same way as on Ajax’s own devices.
Installation is simple: the module is wired into the sensor housing or universal mounting box; setup is done via a smartphone app.
Main features
-
Compatibility with all Ajax hubs and signal boosters (range-extenders).
-
Supports third-party wired devices with NC or NO contact.
-
It is possible to choose whether the sensor signal is processed as a pulse or bistable.
-
The module is capable of powering a connected sensor with a 3,3 V output.
-
Alarm types can be configured: intrusion, fire, medical, panic button, gas alarm, etc.
-
Built-in sabotage protection: the accelerometer detects and warns of removal or opening of the housing.
-
Two-way wireless communication with encryption and jamming detection.
-
Operation and communication with the Jeweller protocol (868 MHz), ensuring stable and secure communication with the hub.

For whom and for what
The Ajax Transmitter is ideal for those who want:
-
integrate existing wired sensors (e.g. old doors/windows, smoke/gas/leakage detectors, panic button, water leakage protection, etc.) into the Ajax alarm system without having to rebuild the entire system;
-
save costs – use old wiring system + Ajax wireless modules;
-
add flexibility and convenience to the surveillance or monitoring system (smart management, mobile app, clear notifications, CMS compatibility);
-
installing equipment in more complex locations (outdoor conditions, boxes, different types of sensors) and ensuring stable signal transmission;
-
add sabotage protection – detection of removal or relocation.
