Ajax Transmitter Jeweller Wireless integration for third-party wired devices
Module for integrating third-party wired detectors into an Ajax system. Transmitter allows to connect IR barrier, liquid level detector, gas leak detector, keypad, panic button or any other device with NC/NO type contact to Ajax.
Principle of Operation
Transmitter allows a detector or third-party device with a wired output to be connected to the Ajax security system. The module receives alarm and event information via a wired connection. After receiving an event, it transmits it to the hub via the Jeweller wireless communication protocol, and the hub informs the security institution and system users.
Specifications and functions
Transmitter works with any detector, keypad, or device with an NC/NO contact type. The module supports many types of events: intrusion, fire, emergency help, panic button, gas alarm, malfunction, flooding, etc. The type of event depends on what alarm code should be sent to the alarm receiving center and what is written in the notifications the user receives. This ensures an appropriate response to the threat.
Installation and Mounting
To add Transmitter to your security system, simply scan the QR code in the Ajax application. You can set the type of wired device connected in the Ajax applications for smartphones and PCs. The module is compact and easy to install in a detector case or mounting box. Transmitter's built-in accelerometer alerts in case of sabotage attempt.
