Transmitter Jeweller Integration Module for One Wired Detector
SKU AJ-42854
- Fast shipping from four branches
- 30-day returns on unopened products
Brings one existing wired detector onto an Ajax system without replacing it. On a takeover where a hardwired device is perfectly good, or a specialist sensor has no wireless equivalent, this keeps it in service.
Built for the installer
It accepts NO or NC contacts with a cable run up to 425 feet on 24 AWG twisted pair, which is far enough to reach a detector in another part of the building. Fourteen wired device event types are selectable, so the device reports as what it actually is rather than as a generic contact.
It also powers the connected device at 3.3 V up to 125 mA, which covers most wired detectors without a separate supply. An accelerometer alerts if the module itself is moved, and there are terminals for the connected device's own tamper.
Key features
- Keeps an existing wired detector in service rather than replacing working hardware
- Powers the connected device at 3.3 V up to 125 mA, usually with no separate supply
- 14 selectable event types so the device reports as what it is
- Cable runs to 425 ft on 24 AWG twisted pair
- Accelerometer and tamper terminals covering both the module and the connected device
System requirements
Requires an Ajax hub or range extender. One wired device per module. For multiple devices use MultiTransmitter, which supports 18 zones.
