A conventional non – addressable system usually included a fire alarm control panel (FACP). FACP receives information from device throughout the property, which is designed to detect associated with a fire event, including water flow or detection of smoke. A map of the building is often placed at a strategic location with the defined zoned and indicators that illuminate when a zone is in an alarm condition. The main drawback is that the activated device can not be detected, and only zone can be identified. The fire may be in only one small area, but the emergency indicators only reveal that the larger zone is in alarm. This type of system is also capable of dialing on offsite monitoring service, shutting down gas supply, turning on smoke exhaust fans, and connecting to other fire alarm panels.
