Features
Transmitter Jeweller
Module for integrating a third-party wired device into the Ajax system. Transmitter allows you to connect the IR barrier, liquid level detector, gas leak detector, keypad, panic button, or any other device with the NC/NO contact type to Ajax.
-
Authentication to protect module against spoofing
-
Jamming detection and transmitted data encryption
-
Two-way secure communication between the module and the hub or range extend

Overview:
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.
The communication range can be up to 1,600 meters provided that there are no obstacles and the case is removed.
Transmitter is set up via a mobile application for iOS and Android based smartphones.
Key Features:
- Connecting a device with a NC/NO contact type
- Supporting pulse or bistable operation mode
- 3.3 V--- power supply for a connected wired device
- Quick pairing with the security system via QR code
- Selecting one of numerous types of wired device events
- Remote control and configuring via the Ajax apps
Compatibility with wired devices
Transmitter works with any detector or device with a NC/NO contact type. The module supports one of numerous event types to notify of the connected device alarms: intrusion1 f1re1 auxiliary alarm1 panic button1 gas alarm1 ma function1 leakage1 etc. The type of event determines the a arm code sent to the security company monitoring station and the notification text received by the user. This ensures an accurate response to the threat.
Jeweller
Encrypted Two-Way communication
The security company and users know exactly which device was triggered, the type of the device alarm, and when and where it happened. Informative notifications and encrypted two-way communication are provided via the Jewel er radio protocol.
The maximum Transmitter radio communication range with a hub or range extender is 1,600 meters in an open space. The protoco uses device authentication for each communication session to protect the module against spoofing.
Quick Pairing and installation
To add Transmitter to the system, just scan the QR code. Installers can change the connected device settings in the PRO apps, on site and remotely. The type of a connected wired device is configured in the Ajax mobile and desktop apps.
The compact module can be insta led inside the detector enclosure or in the mounting box. The maximum cable length for connecting a third-party detector or device is 130 meters (24AWG twisted pair). The bui t-in acce erometer and tamper alarm notifies of an attempt to sabotage the wired device.

Recommendations
Transmitter Jeweller should be installed inside the wired detector enclosure. The module requires a minimum space with dimensions of 4.33″ × 1.61″ × 0.94″. If it is not possible to install Transmitter Jeweller within the detector’s enclosure, any available radiotransparent casing can be used.
