Transmitter Jeweller
A compact wireless integration module that connects third‑party wired detectors to the Ajax security system. Transmitter Jeweller enables legacy sensors to operate as full‑featured Ajax devices, providing encrypted communication, tamper detection, and detailed event reporting. It is ideal for upgrading existing wired infrastructure without replacing detectors.
Key Features
- Integrates wired detectors (NO/NC) into the Ajax system
- Tamper input for enclosure protection
- 3.3 V power output for powering connected wired devices
- Jeweller encrypted communication up to 1,600 m
- Pulse or bistable alarm modes
- Supports multiple event types including intrusion, fire, gas, panic, leakage, and custom
- Up to 5 years battery life on 3 × CR123A
- Built‑in accelerometer for removal detection
- Temperature sensor with real‑time reporting
- Compact 100 × 39 × 22 mm module suitable for detector housings
- Works indoors or outdoors when placed in a sealed enclosure
System Integration
Transmitter Jeweller allows installers to connect:
- Outdoor PIR detectors
- IR barriers
- Float sensors
- Gas detectors
- Thermal relays
- Panic or medical buttons
- Any third‑party NO/NC wired device
Once connected, the wired device behaves like a native Ajax detector:
- Full app visibility
- Room assignment
- Event type selection
- Alarm code mapping for CMS
- Scenario triggers
- Remote configuration via Ajax PRO apps
This makes Transmitter ideal for hybrid upgrades where existing wired infrastructure must be preserved.
