The HM-612PC-2 2-wire network photoelectric smoke detector is designed with no need to distinguish the positive and negative poles for power wiring. After the alarm, it can reset after the power outage. Being the non-coding conventional type, the product adopts the MCU circuit design, and can be dustproof, pest immune, and resistant to the white light interference. It makes use of the huge difference between the current before and after the alarm to let the controller identify the alarm signal.

In addition, the 2-wire network photoelectric smoke detector can also connect the remote LED. Compatible with the conventional fire alarm control panel in the market, it is CE and EN54-7 compliant.
