24-Hour Zone

A zone that is permanently active, 24 hours a day (such as a fire zone).

Entry/ Exit Zone

A zone in a home or commercial space that is used to enter or exit the premises. in homes, these zones monitor front and back doors as well as garage doors. for commercial spaces, these zones usually protect the front door and back doors.


Each device on a wireless security system is its own zone. on hardwired security systems, users may have many similar devices on one zone. for instance, every window contact in the living room may be programmed into the same zone. zones are used to identify which alarm device triggered the alarm event to occur, so that the central station operators can provide specific information to the responding authorities.

Zone Descriptor

A phrase that identifies the type of alarm device connected to a security system as well as the location assigned to that device. a motion detector in the living room might have a zone description of “living room motion.”

Zone Expanders

Devices that provide additional zones for a security system beyond the control panels default capabilities.
