Dry contact Explosion- proof UV flame detector A705/UV Fire alarm relay output Fault relay output EXdⅡCT6
Product function and composition
A705/UV can be applied to the need to monitor the implementation of the fire place, quickly found that the fire may cause the burning flame, issued in a timely manner
Fire alarm.
A705/UV using the cold cathode ultraviolet photoelectric tube to convert the flame combustion parameters into electric pulse signal, then the signal input is calculated.
Chip for operation and processing, with the UVdetecter anysafe dedicated intelligent control software, can be issued in a timely manner to the fire alarm.
A705/UV uses the aluminum die-casting flameproof shell, has good protective properties and explosion-proof, corrosion resistance, aging resistance, can work for a long time
Indoor, outdoor, and various special industrial locations
Sensor sharp probe AE-S708/4 and AE-S708/5 infrared pyroelectric sensor
Optical window white gems (Al2O3)
housing
L material: aluminum alloy
L molding process: Die Casting
L coating process: surface electrostatic powder coating, internal metal passivation treatment.
The weight is less than 1kg
Explosion proof and protection l anti explosion: EXd II CT6

Working parameters
Project specifications or status
Minimum standard of power supply
18VDC (can be customized 12VDC) 30VDC 24VDC
The current monitoring status of less than 20mA, the alarm state is less than or equal to 35mA
Pre heating time 60s
Fire alarm when the monitored area is found in the fire, the detector into the fire state;
Fire alarm output relay action, red fire indicator light;
Fault alarm
When the sensor, power supply and other anomalies are found, the detector enters into the fault alarm state;
Fault output relay action, yellow fault indicator light;
When the fire and failure occurred at the same time, the priority of the fire;
Multistage adjustable alarm threshold (by bar set)
Monitor the state each time the green light flashes to indicate the alarm threshold
Alarm delay 0-30S adjustable (factory set to 0S)
Drift compensation intelligent software compensation model
Can effectively compensate for the temperature, environmental changes and components of the long-term work of drift
Interference source suppression can effectively suppress the impact of non flame interference sources, such as the sun (direct and reflection), commonly used artificial light source, welding
etc.
Indicator light
L monitor status: green light
L fire status: red light always light
L fault status: yellow light is always bright
