Wireless smoke detector Ajax FireProtect 2 43378.137.WH1 — battery-powered, wireless, white

Ajax FireProtect 2 is a battery-powered wireless smoke detector in a compact white housing designed for integration into the Ajax security ecosystem. The device senses smoke and rapid temperature rises, triggering a loud local alarm and sending remote notifications to connected hubs and user apps. Its wireless communication supports quick installation without running cables, and the battery operation enables placement anywhere within the radio range of the system.

Advantages

The detector combines optical smoke sensing with a temperature sensor to improve detection of both smoldering and fast-flame fires. Wireless connectivity ensures signals are relayed to the hub for central monitoring and remote alerts. The built-in siren provides immediate audible warning on site, while low-battery and fault reports help maintain reliable operation. The compact white design allows discreet placement on ceilings or walls.

Suitable for

• Residential rooms such as living rooms, bedrooms and kitchens (outside direct cooking zones)
• Small offices and commercial premises requiring fast smoke detection
• Integration into smart home and security systems for centralized alerts

Key specifications

• Power source: user-replaceable battery operation for flexible placement
• Detection methods: optical smoke detection combined with temperature sensing
• Alerting: built-in audible siren plus wireless notifications to the security hub and mobile app
• Installation: wireless connection to hub, suitable for ceiling or wall mounting
• Housing color and form factor: compact white enclosure designed for unobtrusive indoor use

How to use

Install the detector on a ceiling or high on a wall in the protected area, following the hub manufacturer’s recommended radio range and placement distances from cooking appliances and ventilation. Insert the supplied or replacement batteries, pair the device with the Ajax hub using the system app, and check signal and sensor status in the app. Periodically test the detector using the built-in test function via the app or local test button to verify detection and alarm functions.

Usage recommendations

Place the detector on ceilings in sleeping areas and common rooms, avoid mounting directly above stoves or in very dusty or humid locations. Perform regular battery checks and system tests, and keep the sensor clean of dust. Use the detector as part of a broader fire safety plan that includes escape routes and additional detectors where needed.
