Also known as a smoke loop this circuit uses low voltage smoke detectors powered by the alarm system panel. Smoke detectors are very useful in detecting smoke or fire in buildings and so are the important safety parameters.

In a typical home fire occupants have just minutes to escape. In this project we are going to build a simple smoke detector circuit without using any microcontroller this circuit triggers the buzzer whenever it detects smoke or fire near by it. Unlike standard 110 volt home smoke detectors which only make noise at the house the low voltage units allow fire alarms to be reported to a central monitoring station. Smoke alarms provide the earliest warning of both fire and smoke.

All of the smoke detector wiring is connected to the fire alarm zone on the panel and is fully supervised as if it were a single run.
