4 Wire Conventional Infrared Beam Smoke Detector Fire Alarm
Brief introduction
AW-BK801 Infrared Beam Smoke Detector (hereinafter referred to as detector) is a long-interval reflection line infrared beam smoke detector which must be used together with a reflector.
Application Places
Warehouses, large-scale storage areas, shopping plazas, body-building centers, gymnasiums, exhibition halls, hotel halls, printing works, costume plants, museums, prisons, etc, as well as space with light smoke dust.
Working principle
In case of smoke on the light path of the detector, the signal arriving at the receiver is reduced;
--when the light reduction rate reaches the preset threshold, the detector will produce the alarm signal;
--when the light beam is completely blocked, the detector will produce the fault signal to prevent the false alarm caused by non-fire blockage.

Characters and Advantages of the line beam smoke fire detector
1. Has a built-in uniprocessor with excellent performance;
2. Wide operating voltage range and wide protective area
3. Self-diagnosis capability, monitoring of faults in the detector
4. Field setup of two levels of sensitivity
5. Built-in microprocessor, intelligentized fire alarm and fault judgment
6. Fire alarm and fault passive output contacts and standard 4-20mA standard power supply output
7. Smart design of the detection light path, high antijamming performance, seal protocol, corrosion protection and waterproof performance
8. Integration of the transmitting part and the receiving part, simple and convenient installation, good light path collimation
9. Automatic compensation function, and automatic compensation for factors of received signal reduction such as dust pollution, position deflection, ageing of the transmitting tube, etc. to some extent
10. Automatic calibration function to enable a single person to complete debug within a short time, simple operation, easy integration of the transmitting part and the receiving part, simple and convenient installation, good light path collimation
Technical Parameters
| Operating Voltage | DC16V~DC32V |
| Adjusting Angle | -6 DEG ~+6 DEG |
| External Dimensions | 206mm×95mm×95 mm (length×width×thickness) |
| Material and Color of the Casing | ABS, white |
| Weight | 450g |
| Light path Length | 8m~100m |
| Operating Current | monitoring current ≤12 mA, alarm current ≤22mA, debugging current ≤20mA |
Indication of status of the detector
| 1) Debugging Status: the green, red and yellow indicator lamps light up or flash in a specific mode. 2) Normal monitoring status: the green indicator lamp flashes periodically. 3) Fire Alarm: the red indicator lamp keeps lighting;the yellow indicator lamp blacks out. The fire alarm should be cancelled through being powered again. 4) Fault: the yellow indicator lamp keeps lighting; in case of fault recovery, the fault signal of the detector is automatically cancelled by the detector. 5) If the light path is completely blocked, the detector reports a fault and the yellow indicator lamp lights up.
