There are mainly four types of fire alarm systems: Conventional, Addressable, Analog, and Wireless.

• Conventional fire alarm systems are the most basic and cost-effective systems.

• Addressable fire alarm systems are more advanced and can pinpoint the exact location of the fire.

• Analog fire alarm systems are similar to addressable systems but can also detect changes in the environment that may indicate a fire.

• Wireless fire alarm systems use radio frequency to communicate between de...read more
