SMOKE AND FIXED TEMPERATURE DETECTOR MODEL : YD-818
component of the electric circuit adopts
CPU and SMT technology, small size, high
precision and stability, also low power
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.
has a monitoring light operates every 16
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.
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.
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.
water discharger is installed on the main
body of the detector to eliminate the false
alarm and breakdown caused by accumulated
detector has passed strict quality control
and repeated tests, which has stable quality
and high reliability.
Smoke Detector Type A, B, C
Fixed Temperature 2 types
