The MultiTransmitter has 18 wired zones.

Compatible with the Ajax Hub, Hub Plus, Hub 2 and Hub 2 Plus.

Communicates with a hub via an encrypted Jeweller radio protocol.


Each wired device/zone can be labelled on the App. Therefore, push notifications can inform you when and where the alarm has been triggered.

The wired detectors which are connected to the MultiTransmitter zones benefit from Ajax features. This includes, entry and exit delays, “always active”, siren activation and automation scenarios, all of which can be controlled by the user from the Ajax App.

There are five types of alarms available: intrusion, fire, medical assistance, panic button and gas alarm.

Principle of operation

The MultiTransmitter has a power cable, but during electricity loss, a backup battery can provide power to the wired devices. It is also equipped with two tamper switches which alert the user when it is removed from its mount or when the lid is opened.

Please note: the MultiTransmitter does not come with the 12V backup battery.
