This wireless sensor detects abnormal amounts of smoke in its vicinity. Once triggered, the sensor emits an audible alarm and sends radio frequency (RF) signals to your DSC alarm system. Photoelectric smoke detectors are designed to sense slow, smoldering fires which can kindle for hours before bursting into flames, putting you more at risk for smoke inhalation. Ideal for living rooms, bedrooms, or other rooms that do not contain highly combustible materials that can create flaming fires.
