Supply explosion-proof heat detectors, devaluation giant Shanghai amount. The Shanghai the amount giant supply fire explosion-proof equipment, explosion point type heat detectors giant amount of supply in Shanghai fire explosion-proof equipment, explosion proof point type heat detectors, Shanghai amount giant the supply fire explosion-proof equipment, explosion-proof point type heat fire detectors BXT-3 - proof heat detectors is a two-wire switch detector, and supporting the use of any of the domestic and foreign manufacturers of fire alarm control. When the heat of the fire so that the ambient temperature rises to a predetermined alarm temperature detector, the detector indicator light, to send 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. Main technical parameters 1, explosion-proof in the form: flameproof, Ex-mark: ExdIIBT6 \ ExdIICT6 3, ambient temperature: -20 ° C to +50 ° C, relative humidity: ≤ 95% RH (non-condensing), operating voltage : DC20V ~ DC27V 6, quiescent current: ≤ 60Ua 7 Alarm current: 10mA ≤ 1 ≤ 30mA 8 wiring: The Promise of the two-wire 9, the protection of the area: the space of 6 to 12 meters in height, to protect an area of ??80 square meters; space height in meters to protect an area of ??60 square meters and 10 Dimensions: 135 × 152 × 105mm 11, mounting dimensions: 104mm 12, Weight: 1.2kg Line caliber 2-M22 × 1.5 (Line caliber The number and size can be based on user needs production)
