Temperature Alarm Sensor WS-884

Product description:

     This product is a fixed-temperature temperature-sensing fire detector, which works according to the principle of sensing smoke particles. Adopting unique structural design and photoelectric signal processing technology, it has the functions of dust-proof, insect-proof, and anti-interference from external light. The design ensures the stability of the product. This product has better resistance to visible smoke produced by slow smoldering or bright burning Good response. When the smoke concentration exceeds the standard or the ambient temperature exceeds 57°C, the detector sends out an alarm signal. The product is suitable for indoor environment monitoring such as residences, shopping malls, hotels and warehouses.

    Optional coverage area: When the height of the space is 6-12 meters, the protection area of a detector is 80 square meters for the general site; when the height of the space is less than 6 meters, the protection area is 60 square meters. The specific parameters shall be subject to the design specification for automatic fire alarm system GB50116-98.

Features:

        This product is a non-coded smoke detector with a pair of switch output contacts, which can be normally open or normally closed output according to actual needs. During normal operation, the indicator light flashes once every 9 seconds; when an alarm occurs, the indicator light is always on, and the alarm output contact is activated at the same time.
