This Firex smoke alarm is designed to detect smoke and provide an acoustic warning signal in case of smoke or fire development. The product is used for fire detection in indoor spaces and is suitable for use in homes, hallways, landing areas, and office environments. The smoke alarm operates based on optical smoke detection and is connected to the 230-volt mains power. For continuity during power outages, the smoke alarm is equipped with a 9-volt backup battery. The smoke alarm can be wired to other Firex smoke and heat detectors. When one detector alarms, all linked detectors are activated simultaneously. The smoke alarm features an alarm memory that can determine which detector was triggered first within a linked system.

Explanation of extra features Wired linkable system The smoke alarm can be wired to other Firex smoke or heat detectors so that all detectors alarm simultaneously upon detection. Alarm memory The alarm memory shows which smoke alarm was activated first within a linked installation. Contamination compensation This function automatically corrects for sensor contamination to reduce unwanted alarms. Energy-efficient design The smoke alarm is designed to consume significantly less power than previous generations of Firex smoke alarms. Explanation of detection types Optical smoke detection works by measuring smoke particles in the air using a light source and sensor. When smoke disrupts the light beam, the alarm is activated. Thermal detection measures temperature changes and can be applied to heat detectors within linked systems. Combination detection combines multiple detection methods within one alarm system. Carbon monoxide detection measures carbon monoxide gas and is intended for gas detection, not smoke detection. Explanation of standards EN 14604 is the European product standard for smoke alarms and describes requirements for smoke detection, alarm volume, reliability, and test methods. NEN 2555 is the Dutch standard for smoke alarms in homes and aligns with requirements from the Dutch Building Decree. BS-EN 14604 is the British adoption of the European standard EN 14604. CE indicates that the product complies with applicable European directives concerning safety, health, and environmental protection. Ask a product question
