Smoke Detector FireAngel SB5-INT

The FireAngel SB5-INT is a wireless optical smoke detector designed for reliable early warning of smouldering and visible fires. Powered by a long-life 9V battery with an expected service life of five years, the detector combines compact dimensions (9 cm diameter, 35 mm height) and low weight (113 g) to allow discreet installation on ceilings or walls in domestic and small commercial spaces. Its optical chamber senses particulate from smoke and triggers an audible alarm to alert occupants promptly.

Advantages

The compact, low-profile enclosure enables installation in rooms with limited ceiling space while maintaining effective smoke sensing. The integrated 9V battery provides up to five years of operation without the need for frequent battery replacement, reducing maintenance. Wireless operation simplifies siting the unit away from power sources and allows flexible placement. The optical sensing technology is suited for early detection of smouldering fires and slow-developing combustion, contributing to occupant safety.

How to use

Mount the detector on a ceiling or high on a wall following the manufacturer’s recommended placement away from direct airflow sources such as air vents or fans. Install the 9V battery according to polarity markings, then perform the built-in test function to verify correct operation and audible alarm. Regularly test the unit at intervals recommended by local safety guidance and replace the detector or battery as indicated by the device end-of-life notification or when the unit fails a test.

Usage recommendations

Position the detector centrally within rooms where smoke would first appear and avoid mounting near kitchens or bathrooms where steam or cooking fumes are frequent; if required, use a detector with appropriate cooking-stable features in those locations. Keep the optical chamber free of dust and paint during installation and clean the exterior regularly according to the manufacturer’s instructions. Replace the battery or the entire detector when the unit indicates end of life to ensure continuous protection.
