Description
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.
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.
