Fire detector Ajax WRL FIREPROTECT 2 SB/HSC White, wireless smoke and heat detector

Ajax WRL FIREPROTECT 2 SB/HSC White is a wireless smoke and heat detector in a compact white housing. It combines an optical smoke sensor and a temperature sensor to detect both smouldering combustion and rapid temperature rise. The device operates with two non-replaceable lithium batteries and communicates with the Ajax security ecosystem for local and remote alerting. Its form factor and defined operating temperature range make it suitable for residential and small commercial installations.

Advantages

The detector integrates smoke and heat detection in a single wireless unit, reducing the need for separate sensors. Battery-powered operation enables installation without wiring and ensures continued function during power outages. Built for compatibility with Ajax systems, it supports remote monitoring and management through the platform. The compact white design allows discreet mounting on ceilings or walls.
