Two Way Wireless Smoke Detector

The FW2-SMK is a two way wireless photoelectric smoke detector using low current technology.

The detector automatically compensates for long-term environmentally induced changes to maintain a constant smoke sensitivity. When the drift compensation has reached its high or low limit of adjustment, the detector will go into the trouble state.
