  • AC powered Smoke Detector Alarm

    Contact NowAC powered Smoke Detector AlarmThis detector detects the smoke by a couple of infrared diodes. The principle of detecting is granule in the smoke can reflect infrared light. Infrared diodes are placed in the special chamber. The chamber can shield external light, but don't affect the smoke into it. While have no smoke, the diode can receive very weak infrared light. When the smoke entering the chamber, diode can receive more and more light, when the smoke attains the certain density, the detector can give out alarm signal. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal. The detector adopts the special structure design and ASIC, has the dustproof, mothproof and anti outside light interference feature etc.Read More

  • 2 wire photoelectric heat detector AJ-521

    Contact Now2 wire photoelectric heat detector AJ-521This product named fixed temperature heat detectors is suited to virtually any commercial. The detector responds in alarm if the temperature goes above the trip point. This unit is made up of an externally mounted thermistor with a specially designed cover that protects the thermistor while allowing maximum air flow. The thermistor reads the temperature from the air it takes in. It then transmits a signal representing the temperature to the panel. If the temperature exceeds the trip point, an alarm occurs. The status LED lights during the alarm period. The detector is suitable for detecting the heat in house, shop, hotel, restaurant, office, building, school, bank, library and etc.Read More
