Product Name: Electrical Fire Detector for Electrical Fire Monitoring Wiring Mode: Bus System Receive Frequency: 50-60Hz Alarm Volume (within 1m): ?80dB Certification: CCC Usage: Door Function: Non-Networked Type: Wireless Alarm Host Transport Package: Package Origin: China Product Description The fire monitor integrates various functions such as residual current detection, alarm, trip, and CAN bus communication, and has intelligent analysis capabilities. It is a new type of fire protection equipment. When an electrical accident occurs in the power supply equipment, the detection controller can issue The sound and light alarm promptly reminds the staff to check the fault, eliminate potential electrical hazards, and prevent accidents. The fire monitor is suitable for the fire safety protection of electricity in residential areas, hospitals, libraries, machine rooms, public cultural and entertainment venues, restaurants, hostels, collective dormitories, schools, cultural relics protection units, factory workshops, general warehouses and other areas. But it is not suitable for flammable, explosive and highly corrosive environments. The fire monitor can be installed separately for the protection of relatively independent power consumption areas, or can be networked to form an electrical fire monitoring and alarm system. The fire monitor implements the national standard GB14287.2-2014 "Residual Current Type Electrical Fire Monitoring Detector". 1. Basic functions1. Real-time monitoring The fire monitor can monitor the residual current of the controlled circuit when it is realized.2. Alarm protection function The fire monitor can detect the residual current of the circuit, if it exceeds the limit, an audible and visual signal is issued to alarm, and the power supply circuit can be cut off within the specified time.3. Communication function The fire monitor is equipped with a CAN communication interface. Can communicate with the host of the monitoring equipment through CAN bus communication to achieve remote management, maintenance and monitoring.2. Main technical parameters1. Rated working voltage AC 220V2. Alarm and protection of residual current over limit(1) Alarm setting value: 50mA-999mA (+ 5%) continuously adjustable, step size is 1mA(2) Rated residual operating current: 50mA-999mA continuously adjustable; (3) Rated remaining non-operation current: 20mA-1000mA continuously adjustable.3. Protection action time: <0.5s;4. Alarm sound:> 70db;5. Alarm output: switch type, contact capacity AC250V / 3A;6. Communication method: CAN communication <1km7. Use environmental conditions 1 Ambient temperature: -20 ºC ~ + 40 ºC 2 Relative humidity; 10% -90% 3 Altitude; not more than 3000m4 Use place; with rainproof facilities8. Installation type: guide rail installation.9. Running indicator: Shows whether the detection controller is running normally. During normal running, the running light is always on.10. Communication indicator; whether the communication between the detector and the host computer is normal. When normal, the communication indicator should flash.11. Alarm (trip) indicator: when the leakage current reaches 90% of the alarm value, the alarm indicator flashes red, when the alarm value is reached, the indicator is always on and accompanied by an alarm sound, which means that Leakage overload and other situations in the electric line remind the staff to solve the problem in time.Specification:LeakingchannelMax.12Leftpowerinput0~2000mALeftpoweroperatevalue30~1000Ma,adjuststep1mALeftpoweralarmvalue30~1000Ma,adjuststep1mAOperatedelay0~60s,interval0.1sOverload10times,moment40times/secondTem.testedrange0~150ºCCommunication1channel485,MODBUS-TRUDI1channel,activeAC220V+/-25%DO1channel,relayoutputAC220V/5A,DC30V/5AWorkingpowerWorkingvoltageAC/DC:80V~270VPowerconsumption<2VAWorkenvironmentWorktemperature-20ºC~60ºCStoragetemperature-40ºC~75ºCHumidity5%~95%,nocondensationSafeInsulatingstrengthIsolationresistance:≥2MΩWithstandvoltage:2kV1min.
