How Do Fire Alarms Work?

Fire alarms are controlled by a central operating system. The central operating system is connected to the various smoke and heat sensors installed throughout the home or office. When there is a fire in the house or smokes coming out the sensors are activated and an alarm is sounded. This may send a signal to an external monitoring service or agency to inform the police or the fire services department about the emergency.

It is important to place the sensors in such areas where they cannot be activated accidentally by smoke from the shower or heat from the kitchen.
