The GLH-9A indoor smoke detector is designed with ultra-low power wireless networking technology. It is an early warning device that can monitor and detect the presence of smoke in real time. Once a smoke fire hazard is detected, the detector's red LED indicator light will immediately flash rapidly and emit an alarm sound to remind you and your family in a timely manner. Smoke detectors should be installed in all guest rooms, living rooms, storage areas, basements, and attic units in households where fires may occur.
