Ajax Transmitter Jeweller Wireless Module for One Wired Detector

Overview

The Ajax Transmitter Jeweller is a small radio module that connects one wired detector from another brand to an Ajax alarm. It fits inside the detector’s own housing, takes its alarm and tamper contacts, and powers the detector from its own batteries, so an existing wired sensor can join a wireless Ajax system without running cable to the hub.

Is it right for you?

• Choose it to keep a wired detector you already have, or to add a type Ajax does not make, such as a seismic sensor or a gas detector.
• One module connects one wired device. Each extra device needs its own Transmitter.
• The wired detector must run on 3.3 V DC at up to 125 mA from the module, or have its own power.
• It is not compatible with the uartBridge or ocBridge Plus integration modules; it needs an Ajax hub.

Key features

• One alarm input and one tamper input, each accepting normally open (NO) or normally closed (NC) contacts, wired in the AATT scheme.
• 3.3 V DC output at up to 125 mA to power the connected detector.
• Cable run to the detector of up to 130 m with 24 AWG twisted pair.
• Pulse or bistable operating modes, and the input can either report alarms or switch arming modes.
• 14 event types to choose from, including intrusion, fire, panic button, gas, leakage, glass break, masking, vibration and custom.
• Jeweller radio to the hub or range extender up to 1,600 m in open space, encrypted with frequency hopping.
• Accelerometer alerts when the module is moved; communication loss reported after 36 s.
• Runs on three CR123A batteries, pre-installed; battery life depends on the connected detector’s consumption.

What else you need

An Ajax hub or range extender. Compatible models include Hub (2G), Hub (4G), Hub Plus, Hub 2 (2G), Hub 2 (4G), Hub 2 Plus, Hub BP, ReX, ReX 2, Superior Hub G3, Superior Hub Hybrid, Superior Hub Hybrid 2, Superior MegaHub, Superior ReX G3, EN54 Fire Hub and EN54 Fire ReX.

A wired detector with NO or NC alarm contacts, and a tamper contact if you want tamper reporting.

The Ajax app, where the event type, operating mode and settings are set by an installer (PRO) or a user with admin rights.

Installation

An alarm installer should fit it. The module goes inside the wired detector’s enclosure and needs a space of at least 110 x 41 x 24 mm; if there is no room, any radio-transparent casing can be used.

Wire the detector’s alarm and tamper contacts to the ALARM and TAMP terminals and, if the detector is powered from the module, to the 3.3 V output.

Before you buy

Not compatible with uartBridge or ocBridge Plus.

Rated from -25 to 50 °C and up to 75% humidity; the board measures 100 x 39 x 22 mm and weighs 74 g.

Battery life depends on how much current the connected detector draws.
