4-Wire Network Photoelectric Smoke Detector

The HM-612PC-4 4-wire network photoelectric smoke detector is designed with non-polarity power input. Its alarm output is normally close or normally open on-off signal. Certified by the LPCB EN54-7, the non-coding type product has a pair of on-off output contacts. The normally close or normally open output is optional in line with the actual needs. When the product is in normal working status, the indicator flashes once every 10s. When the product is in the alarm state, the indicator keeps light, and the product gives the alarm and outputs the contact action.

The 4-wire network photoelectric smoke detector is resistant to the radio frequency interference of 20V/m-1GHZ. It can achieve automatic resetting and resetting after power off. The user can choose the needed mode via the DIP switch at the bottom of the product. Meanwhile, the product can match all the fire alarm control panels in the market. With good reaction to the visible smoke generated by the slow smoldering or the flame combustion, it can be employed for detecting the smoke in residential area, factory building, shopping mall, hotel, warehouse, etc.
