Multi-spectral flame detector signal acquisition mode / full-frequency wave analysis technology, to avoid the weaknesses of the traditional detector susceptible to interference. The slope incremental signal detection technique (PAM) for detecting environmental monitoring, improve detector stability and sustained usability. Ensure the ability of the detector to minimize false alarms at the same time, quickly identify flame to detect a fire. Applicable to all types of detectors: depot, wine storage, hangars, chemical equipment space, military equipment sites, gas stations, power plants and other non-smoldering fire smoldering stage or less germination stage, and to directly produce fire main place. Has high anti-interference ability, not affected by wind and rain, high temperature, high humidity and natural artificial light source, may well work in indoor or outdoor environments. Detector with six-wire connection (two power cords, two fire contact line, the two fault contact line), fire alarm normally open contact normally closed change, when reported by the normally closed contacts of fault Variable normally open, can be connected with any manufacturer's fire alarm system. The main technical parameters: Spectral response: 1.0 ~ 3.2um Response Time: 5 to 10 seconds monitor angle: ≤100 ° Operating voltage: 20 ~ 35V Quiescent current: 25mA ± 3mA Alarm state current: 35mA ± 5mA Sensitivity: 1m ~ 40m at You can respond. (Flame height: 0.1m ~ 1.3m shaking flame) protection: IP66 Explosion-proof mark: ExdⅡCT6 / DIP A20 TA, T6 Ambient Temperature: -35 ~ 85 ℃ Relative humidity: ≤98% RH (45 ± 2 ℃) Adjustable angle : rotation angle: 360 ° / Tilt angle: 90 ° Status Indicator: Green indicator light, normal light, internal device malfunction green light and damage reported. Red warning indicator: normal off, when a fire lit. Output: Alarm relay: normally open alarm closure. Fault relay normally closed, reported the fault often open. Contact rating: 3A / 220V AC 3A / 30V DC explosion junction: 4 "(φ20mm) proof hose outlet tube nut screw connections (explosion detector Figure) implementation of the standards: GB 15631-1995, GB3836.1-2000,3836.2 -2000
