Wireless Smoke and Heat Detector with Built-in Siren Ajax FireProtect Jeweller White
The Ajax FireProtect Jeweller in white is a wireless fire detection solution for residential and commercial premises. The device pairs a photoelectric smoke sensor with a thermocouple to recognize rapid temperature spikes.
It triggers an immediate alarm when the ambient temperature exceeds 59 °C or increases by 30 °C within 30 minutes. To filter false alarms caused by dust or steam, it uses the HazeFlow software algorithm for double verification. Furthermore, it supports interconnected alarms, triggering built-in buzzers on all system fire detectors upon detecting a threat.
#### Standalone Mode & Jeweller Wireless Tech
FireProtect can function connected to an Ajax Hub or in standalone mode. When operating independently, it alerts locally via its 85 dB buzzer and visual LED indicators. Powered by Jeweller radio protocol, it transmits encrypted data up to 1,300 meters in open space.
Running on pre-installed batteries for up to 4 years, it performs automatic health checks on its optical chamber. For official technical details, visit the FireProtect page on Ajax Systems. Discover our products under Ajax wireless detectors at Lisintec.
