Product Description
Introduction of Explosion-proof point type smoke fire detector
XDT-Y-01 explosion-proof point type smoke fire detector, non-code switch type (relay output) detector. Detector adopts infrared scattering principle to detect fire, the circuit is mainly composed of infrared emitting part and receiving part, the transmitting tube and receiving tube are placed in the optical dark room, the optical dark room can shield the interference of external stray light, but does not affect the smoke into. In the smoke-free state, only receive very weak infrared light, when there is smoke into, due to the scattering effect, so that the received light signal is enhanced, when the smoke reaches a certain concentration, can output alarm signal.
Feature of Explosion-proof point type smoke fire detector
1) Excellent explosion-proof performance: the use of this safety flameproof compound structure, explosion-proof mark is Ex db ia IIC T6 Gb, to meet the explosive gas environment requirements of class ⅡC T6 temperature group, built-in safety grid and through special process treatment, to ensure stable work in flammable and explosive places.
2) Advanced core detection technology: The use of infrared scattering technology and advanced optoelectronic devices to improve the sensitivity, stability and consistency of the sensor, and the response threshold range is highly accurate.
3) Strong environmental adaptability: working temperature range -10℃~+55℃, humidity tolerance ≤95% (no condensation), suitable for petroleum, chemical, metallurgy and other high-risk industries. The case is made of cast aluminum alloy, which is resistant to corrosion and durable.
4) Flexible configuration and compatibility: Support normally open (NO) and normally closed (NC) passive contact output, suitable for all kinds of fire alarm controllers at home and abroad. The number and size of inlet can be customized to meet different installation requirements.
5)Convenient and safe maintenance design: alarm reset needs to be powered off and restarted to avoid misoperation; The bottom adopts sealed structure, dustproof and insect-proof, prolonging service life.

FAQ
Q1: Which places are suitable for installing explosion-proof point smoke detector?
A1: Applicable places are petroleum, chemical, metallurgical, pharmaceutical and other containing ⅡC class T6 temperature group explosive gas environment, such as oil depot, chemical plant, gas station, warehouse and so on.
Q2: What are the common causes of detector false alarm? How to solve it?
A2: The common reason is that the sensitivity setting is unreasonable (such as the increase of environmental dust is not adjusted in time); Clogged sampling holes or filters (need to be cleaned or replaced); External interference (such as bright light, hot objects, electromagnetic interference). Solution: Maintain the air filter regularly, adjust the sensitivity level, and replace the air filter to ensure that the installation position is away from interference sources.
Q3: What should I pay attention to during installation and maintenance?
A3: When installing, use M6 expansion screws to fix the ceiling, and connect the cables to the terminals in the explosion-proof cavity. It is strictly prohibited to operate with electric power in inflammable and explosive places. Periodically check performance (quarterly recommended); Clean flameproof surface to avoid damage or foreign body intrusion.
Q4: How to set the sensitivity of the detector? What are the voltage and current requirements?
A4: Sensitivity: Response threshold range 0.10dB/m~0.27dB/m; Voltage/current: working voltage DC24V, static current ≤150uA, alarm current 10mA~30mA; Protection area: Space height 6~12 meters to protect 80㎡, 6 meters below the protection of 60㎡.
Q5: Is it compatible with other fire alarm systems?
A5: Support normally open (NO)/normally closed (NC) passive contact output, can be used with mainstream fire alarm controllers at home and abroad.
