Supply a sense of explosion-proof smoke heat detectors, devaluation giant Shanghai quantity. Shanghai amount giant the supply fire explosion-proof equipment, explosion-proof composite type flu smoke heat detectors, the giant amount of supply in Shanghai fire explosion-proof equipment, explosion-proof composite sense smoke heat detectors, Shanghai amount of the giant supply fire explosion-proof equipment, explosion-proof composite sense smoke heat detectors, BXT-2 explosion-proof smoke detector is a two-wire switch detector, and supporting the use of any of the domestic and foreign manufacturers of fire alarm controller. The detector is connected with the the JDAS type barrier. Barrier resistive transistor dual electronic switching circuit, Kai control speed, output resistance is minimal, and automatic recovery. ??? When the the scene smoke concentration exceeds a set threshold, the detector indicator light, an alarm signal to the controller. Only after a system reset or the fleeting power down because re-power on, the lights did not resume blinking state, this product meets the GB3836-2000 standard requirements of production. 1, Ex-mark Exd (ib) Ⅱ CT6 2, Working voltage DC20V ~ DC28V 3, monitor current ≤ 0.12mA 4 Alarm current 10mA ≤ I ≤ 30mA 5 the response threshold 0.10dB / m ~~ 0.27 dB / m, alarm temperature 60 ℃ 7, alarm reset momentary power failure (10s Min, DC2.5V Max), contact capacity 1A 9, the maximum wind speed of 7.6m / s (1500fpm) 10 lights red alarm acknowledgment normal monitor periodically shiny, alarm , Always 11 to protect the area when space height of 6m ~ 12m, the protected area of ??a detector, generally protect the scene of 80 square meters. Space height of 6m below to protect an area of ??60 square meters. 12, the use of ambient temperature: -20 ℃ ~ +50 ℃ Relative humidity: ≤ 95% non-condensing Atmospheric pressure: 80kPa to 110kPa 13, the line diameter 2-M22 × 1.5 (the line number of caliber and size according to the needs of users design and production) 14, the weight 1.2kg meter production)
