Description:
1. The TA-2988 photoelectric smoke detector is designed to be super-thin with a patch technique and a two-wire and non-polarity system. It has a strong anti-interference capability and low power consumption. It can be used safely in many different situations.
2. The detector's chamber with a y-type labyrinth can dtect effectively the smoke of a smolder fire and smoke given off at the start of a fire. The light-sensitive somponent can detect the light, as the light is scattered in the room after the smoke enters or fills the room. When the light strength attains to threshold of the fire alarm, the light (red) of the detector will be bright, and the alarm signal will be transmitted to the exported equipments.
3. Every unit is individually tested and calibrated to ensure high reliability and prevent false alarms
