What type of smoke detector is used in the power environment monitoring system?
Performance: the alarm sound is not less than 80dB (or silent) power supply: DC9V ~ DC28V current: the quiescent current is less than or equal to 200uA alarm temperature current less than 45mA: -10 to +50 DEG C relative humidity: less than 95%RH (40 - 2 Deg. C) smoke sensitivity: 1.06 +.26%FT. standard: GB4715-2005 output: alarm / relay passive contact (NO/NC set) output.
The detector is widely used in the following fields: communication base station, dynamic environment monitoring, security monitoring, fire control system, intelligent community, building intercom, instrumentation, industrial automation, substation equipment room, safety, tunnel safety, special air conditioning area, elevator maintenance, Ethernet Remote Monitoring etc..
Movable loop monitoring uses a dry contact, an output type of smoke, also known as a smoke switch, or a smoke relay (normally open / normally closed adjustable). Recommend a good homemade smoke detector: JTY-GD-DG311. DG311 smoke detector can access the following equipment: programmable logic controller (PLC), temperature and humidity sensors, intelligent switch signal acquisition display, analog digital collector, all kinds of fire input module, signal acquisition module, alarm host, monitoring equipment, etc. can receive switch the amount of passive contact signal equipment. At the same time, can be through the smoke detector linkage audio equipment, fan etc..
Function: self check: press the check button, the detector LED is always bright, and send out the alarm sound at the same time. (Note: the self-test only detects the internal function of the detector itself, and there is no relay signal output when self checking.). Work: normally, the detector flashes about every 6 seconds. The detector automatically detects the smoke concentration in the surrounding environment, and automatically compensates the sensitivity according to the environmental conditions used. When the smoke concentration is close to the alarm value, the detector speeds up the intelligent operation of the smoke concentration trend, and simultaneously, the alarm indicator lamp starts to flash. If the operation results reach or exceed the alarm value, the detector starts the sound and light alarm and initiates the relay output.
