Ajax security system module for integrating a wired detector or device from a third party. You can connect any device with the NC/NO contact type to Ajax using the transmitter, including the IR barrier, liquid level detector, gas leak detector, alarm button, and more.
Authentication to protect module against spoofing
Jamming detection and transmitted data encryption
Two-way secure communication between the module and the hub or range extender
Makes third-party wired device part of the Ajax security system
Provides 3.3 V⎓ power supply for the wired device
Operates in temperatures from −25°C to +50°С and humidity up to 75%

Operational principles

The Ajax security system's transmitter enables you to link a wired detector or device from a different company. Through a wired connection, the module is notified regarding alerts and events. When it detects an event, it sends a Jeweller radio protocol transmission of the event to the hub, which then alerts the central station and system users.


Any detector or device having an NC/NO contact type can be used with the transmitter. For devices that are linked, the module supports 8 different sorts of events: intrusion, fire, medical assistance, panic button, gas alarm, malfunction, leakage, and custom event. The alarm code that is delivered to the security company monitoring station and the content of the message that the user receives are both based on the type of event. This guarantees a timely reaction to the threat.

Installation and set up

To include Transmitter in the security system, use the Ajax app to scan the QR code. In the Ajax desktop or mobile apps, you can define the kind of wired device that is connected. The module is easy to put within the mounting box or detector body. Additionally, the accelerometer in the transmitter will alert users of tampering attempts.
