The photoelectric smoke detector is designed to sense smoke that comes into the detector chamber. It does not sense gas,
heat, or flame. This smoke detector is designed to give early warning of developing fires by giving off the alarm sounds from its
built-in alarm horn. It can provide precious time for you and your family to escape before a fire spreads.
