Photoelectric & Thermal Smoke Detector - 4 Wire
- Incorporates a state-of-the-art optical sensing chamber and an advanced microprocessor.
- Mounts to octagonal and single-gang back boxes, 4-square back boxes, or direct to ceiling.
- Thermal detectors feature a restorable, built-in, fixed temperature(135°F) thermal detector and are capable of sensing a freeze condition if the temperature is below 41°F.
- Installation is simplified by the use of a mounting base that may be pre-wired to the system.
