Conventional photoelectric beam smoke detector
Brief introduction
AW-BK901 Line Beam Smoke Fire Detector (hereinafter referred to as detector) is a
long-interval reflection line infrared beam smoke detector which must be used together with a
reflector. 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. Thanks to the built-in uniprocessor
with excellent performance, the detector has a powerful analysis and judgment capability and can
automatically complete the systematic debug, the compensation for external environmental
parameter variation, and the judgment of fire alarm and fault, and also can give status indication
through the indicator lamp and the signal output terminal. The detector adopting a brand-new and
reasonable structural design is sensitive in adjustment, correct in positioning, easy in
installation, and simple and convenient in debugging method. The detector contains a group of
alarm passive normally open contacts and a group of fault alarm normally closed contacts as well
as 4-20mA standard signal output to be conveniently connected with the fire alarm system and
DCS system of plants of fire fighting equipment.
Characters:
1.Wide operating voltage range and wide protective area
2. Self-diagnosis capability, monitoring of faults in the detector
3. Field setup of two levels of sensitivity
4. Built-in microprocessor, intelligentized fire alarm and fault judgment
5. Fire alarm and fault passive output contacts and standard 4-20mA standard power supply
output
6. Smart design of the detection light path, high antijamming performance, seal protocol,
corrosion protection and waterproof performance
7. Integration of the transmitting part and the receiving part, simple and convenient
installation, good light path collimation
8. 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
9. 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 flashesperiodically. 3) Fire Alarm: the red indicator lamp keeps lighting;the yellowindicator 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. |
Operating Environment | temperature -10°C~+50°C relative humidity ≤95% withoutcondensation |
Protective Area | the maximal protective area of the detector 14×100=1400 m2 |
