PHOTO SMOKE DETECTOR MODEL : YD-999
 
   
 
   
 

The component of the electric circuit adopts CPU and SMT technology, small size, high precision and stability, also low power consumption.

Transmitter projects beam signal every 3 seconds to check any smoke caused by fire, when smoke density reaches the present standard, the receiver will confirm the signal for 16 consecutive times (once every 0.3 sec), control panel will then receive the fire signal after consumption is made.
The detector is equipped with monitoring light, which goes by 16 sec per frame (flickering). It sends out warning within 0.3 sec when smoke is detected (reaching the standard) for 16 continuous times. If there is dust causing the flickering or discontinuous signals, it will resume the normal monitoring status after 32 times. Insect guard is made of stainless steel that is 0.5mm aperture to prevent the invasion by insects and dust, and decrease the chance of false alarm.
The water discharger is installed on the main body of the detector to eliminate the false alarm and breakdown caused by accumulated water.
This detector has passed strict quality control and repeated tests, which has stable quality and high reliability.
Smoke collecting box: Since the inside easily collects smoke, so it is designed as a foldable box. The feature includes easy assembly, which requires no extra tools. Just turn it to remove the box for cleaning.
