Carbon monoxide detection in the same device as smoke and heat detection provides comprehensive multi-hazard fire and gas protection from a single Ajax system detector. Properties with gas appliances, boilers, gas fires, or oil central heating systems are at risk from CO poisoning if the combustion system develops a fault.
Optical smoke detection identifies fires producing large visible smoke particles from smouldering combustion materials. Heat detection identifies rapid temperature rises from fast-flaming fires. CO detection continuously monitors the CO concentration in the air and triggers the alarm if the level reaches the dangerous threshold defined by EN 50291, the European standard for CO alarms.
The SB designation indicates this detector is designed for self-contained battery-powered operation: there is no requirement for mains wiring to the detector position, and the detector communicates wirelessly with the Ajax hub over the Jeweller two-way radio protocol. Battery life is monitored by the hub and reported in the Ajax app.
The key differentiation from the Ajax FireProtect 2 SB without CO (SKU 52254) is the carbon monoxide sensing element: the no-CO variant omits CO detection and is appropriate for properties without gas appliances or where a separate CO alarm is already installed. The with-CO variant (this product) is the correct specification for any property where CO risk from combustion appliances is present.
For Ajax alarm system installers adding combined fire and CO detection to residential systems across London and the UK, the FireProtect 2 SB with CO provides the complete multi-hazard wireless detector.
