MODEL : YD-318(YD-318D)
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), then the buzzer will be activated (beep, beep, beep).
Detector has a monitoring light operates every 40-50 seconds (flash) during standby status. When there is smoke (reaches operating standard), detector will issue fire signal after 16 consecutive times of confirmation on every 0.3 second, if any dust cause flashing or inconsecutive signal, it will go back to normal operation after the 32 times.
When the power is low, the unit "beeps" every 20 seconds for 7 days continuous warning.
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.
This detector is operated by temperature differential sensing theory, with UL approved high reliability sensor to connect with metal, it is made by high quality material to enhance its ability to overcome the bad environment. (YD-318D)
This detector has passed strict quality control and repeated tests, which has stable quality and high reliability.
