This FireAngel smoke and heat detector, type WST-630T BNLT, is designed for detecting smoke and signaling fire development in indoor spaces. The product is used for fire detection in homes and is suitable for use in bedrooms, hallways, and living areas. The detector operates on Thermoptek® multi-sensor technology, combining optical smoke detection with thermal detection. This allows the detector to respond to both slow smouldering fires and rapidly developing, flaming fires. The detector is equipped with two non-removable lithium batteries with a stated lifespan of ten years. Upon smoke detection, an acoustic alarm signal of 85 decibels is activated. The detector can be wirelessly linked with other compatible FireAngel detectors so that all linked detectors alarm simultaneously.

Explanation of additional features Wireless linkable Wi-Safe system The detector can be wirelessly linked with other FireAngel Wi-Safe detectors so that all detectors alarm simultaneously upon detection. Thermoptek® multi-sensor technology The combination of optical smoke detection and heat measurement ensures faster detection of different fire types. 10-year fixed lithium battery The integrated batteries are designed to power the detector for ten years without replacement. Pause and test function The test button can be used to check operation, and the pause button can temporarily silence the alarm. Explanation of detection types Optical smoke detection detects smoke particles via a light source and sensor and effectively responds to smouldering fires. Thermal detection measures temperature increases and additionally responds to rapidly developing fires. Combination detection combines smoke and temperature measurement within one detector. Explanation of standards EN 14604 is the European product standard for smoke detectors and describes requirements for smoke detection, alarm volume, and reliability. ETSI EN 300 220-2 describes requirements for wireless communication equipment for short-range applications. Ask a product question
