## Long description

Wall-mounted Transmitter Ajax 38184 Wired Wireless Battery CR123A is a compact module that integrates a third‑party wired detector or device into the Ajax security system. The transmitter accepts signals from devices with NC/NO contacts and relays events to the Ajax hub via the Jeweller radio protocol. It provides a 3.3 V⎓ power output for a connected wired device and can operate at temperatures from −25°C to +50°C with up to 75% relative humidity. The unit is powered by a CR123A battery and has dimensions of 39 mm (width) × 22 mm (depth) × 100 mm (height).
Advantages
The Transmitter converts conventional wired detectors (IR barriers, gas detectors, liquid level sensors, alarm buttons and others) into components of the Ajax system while preserving the detector’s NC/NO wiring scheme. It supports eight distinct event types (intrusion, fire, medical help, panic, gas alarm, malfunction, leakage and custom event), ensuring correct alarm codes and user notifications reach the monitoring station and system users. The compact form factor enables installation inside a detector housing or mounting box and the built‑in accelerometer detects sabotage attempts.
Suitable for
Connecting wired IR barriers and motion detectors to Ajax
Integrating gas leak detectors and liquid level sensors
Adding wired panic or alarm buttons to the security system
Converting legacy wired sensors with NC/NO contacts for remote monitoring
