Supply HS-L820I fire detectors Shu HS-L820I electrical fire monitoring

HS-L820I fire detectors Product Overview System should be set at the following location: important low-voltage power distribution room outlet circuit; fire lighting sub-region into the line at the main distribution box, power distribution box into the line of the total; building audience halls, conference rooms and other crowded places distribution box into the line; dance halls, recreation halls and other places of entertainment distribution box into the line; underground mall (shops) distribution box into the line; student dormitories, kindergartens, elderly building places such as distribution box into the line; cultural relics protection units focus brick or wood structures and other places such as distribution box into the line. Electric fire alarm system as a set of independent system, after recent years of practical application and technical updates, has gradually become a modern building fire an integral part. Currently, electrical fire monitoring system has become the preferred solution for electrical safety management, its core is an electrical fire monitoring terminal. Electrical fire monitoring system: When the protection circuit is detected in the parameter exceeds a set value, an alarm signal to the control signal and to indicate alarm system parts, which consists of electrical fire monitoring equipment, electrical fire monitoring detector. HS-L820I fire detectors Features HS-L820I detector performance is stable and reliable, anti-interference ability of the TSL, cold resistance to moisture and strong, and can be used in high altitude areas. Local intelligent processing and communication functions: sound and light alarm and fire between functions; You can manually test circuit and the detector is working properly. HS-L820I for monitoring residual current, temperature, residual current alarm (leakage alarm), over-temperature alarm, fault identification and other functions. HS-L820I fire detectors Technical Specifications Operating voltage: AC220V ± 15%, 50Hz, power consumption: 2W main channel over the line diameter: 80 main channel over the line current: current ≤ 600A residual current alarm value :20-1000mA continuously adjustable temperature alarm value :55-140 ℃ continuously adjustable control output: passive normally open output contact group (AC220V/1A) Communication: RS485 Bus Bus Specifications: Shielded Twisted Pair sectional area :1.0-1 .5 mm2 indicator: Run , alarm, mute, self-test alarm sound: Fault - intermittent sound alarm - continuous tone function keys: test, self-test, silencers, the reset menu keys: menu, up, down, OK, C Auxiliary Channels: 5 a (temperature measurement module, the leakage current module, overcurrent module) Operating environment: Temperature -10 ℃ -40 ℃, relative humidity ≤ 95% Executive Standard: GB14287.2-2005 GB14287.3-2005
