WebPut smoke alarms inside and outside each bedroom and sleeping area. Put alarms on every level of the home. Make sure your smoke alarms work. Your family is not safe if they can't hear the smoke alarms. Test smoke alarms every month and replace 9-volt smoke alarm batteries at least once every year. Smoke alarms do not last forever. WebThere is a photoelectric detector at the other end. It detects the light coming, which tells the system that the circuit is complete. However, when smoke enters inside, the smoke obstructs the light. The redirected light falls into the photocell, which is present inside the chamber. When this photocell detects light, it rings the alarm. important cities in kerala https://ascendphoenix.org
