Name: Point type infrared flame detector

Model: A705/IR2

Sensors: Ruitan AE-S708/4 and AE-S708/5 infrared pyroelectric sensors

Optical window housing: White gemstone (AI203)

Material: Aluminum alloy

Forming process: die-casting

Coating process: surface electrostatic powder spraying, internal metal passivation treatment

Weight: ≤ 1kg

Explosion proof grade: Exd II CT6

Protection: IP66

Working current: monitoring ≤ 15mA, alarm status ≤ 35mA

Preheating time: 60s after power on

Fault alarm: When a flame is detected in the monitored area, the detector enters a fire alarm state;

The fire alarm input relay acts and the yellow fault indicator light illuminates;

Alarm threshold: When both fire and fault occur simultaneously, fire alarm takes priority;

1-3 levels adjustable (set by electromagnetic rod)

The number of times the green light flashes during monitoring indicates the alarm threshold.

Alarm delay: 0-30S adjustable (set to 0S at the factory)

Drift compensation: sensor hardware compensation and intelligent software compensation combined mode

Can effectively compensate for drift caused by temperature, environmental changes, and long-term operation of components

Interference source suppression: can effectively suppress the influence of non flame interference sources, such as sunlight (direct and reflected)

Commonly used artificial light sources, background radiation sources, thermal moving objects, welding, etc.

indicator light:

Monitoring status: green light flashing

Fire alarm status: Red light always on

Fault status: yellow light constantly on

Output:

Fire alarm relay, acting upon alarm, output contact 3A@30VDC 3A@250VAC

Fault relay, acting upon fault, output contact 3A@30VDC 3A@250VAC

Serial communication interface
