LiftMaster Photoelectric Smoke Detector (2 Wires) | LIF-LMPD24-2W

The LMPD24 incorporates a state-of-the-art optical sensing chamber and an advanced microprocessor. The microprocessor allows the detector to automatically adjust its sensitivity back to the factory setting when it becomes more sensitive due to contaminants settling in its chamber.
