FIREPROTECT

The AJAX FireProtect is a wireless fire safety detector combining a photoelectric smoke sensor and dual thermistors for early fire detection, featuring a built-in 85dB siren for immediate acoustic alerts and Jeweller protocol communication up to 1700m to Ajax hubs.
FireProtect 2 variants use bispectral optical sensors (blue + IR LEDs) to distinguish smoke from steam/humidity, trigger on temperatures >64°C or rapid rises (>10°C/min), and support interconnected alarms across multiple detectors with self-diagnostics and 7-10 year battery life.
