General
JTY-GD-S832 point-type photoelectric smoke detector is a photoelectric
smoke detector. As a non-polar two-wire power input is adopted in the detector,
it can detect the smoke and send out alarm signal in time when fire taking
place. As microcontroller is adopted in the detector, it can identify the smoke
concentration intellectually. The detector monitors smoke concentration in the
