Z
Zone
A separate circuit or branch of a security system usually for the purpose of isolating and/or identifying alarms or trouble in a system.
A zone is a length of cable onto which different types of security or fire devices are connected. This zone is attached to the panel on its own set of screw terminals and given its own zone name, such as FRONT DOOR, that can display on system keypads. Multiple zones are typically assigned to an area so that all their protection devices combine to provide complete protection of persons or property inside.
Zone Expander
A device in an alarm system that provides additional zones and allows more than one individual zone to be monitored over one set of wires.
Zone Reports or Zone Message Types
There are four zone messages that can be assigned to a zone for when it is tripped while armed:
Alarm: Alarm reports are sent to the monitoring center and Bell Output is activated if programmed. The alarmed zone name appears in the keypad alarm and status lists as an alarm condition.
Trouble: Trouble reports are sent to the monitoring center and the zone name appears in the keypad alarm and status list as a trouble condition.
Local: Alarm reports are NOT sent to the monitoring center. Bell Output does activate if programmed, and the zone name appears in the panel alarm and status lists.
— (dash): Alarm reports are NOT sent to the monitoring center, Bell Output is NOT activated, and there is no zone display in the keypad status list. If you are using Remote Link or Dealer Admin to program the panel, that option is labelled as None.
Zone Retard
A zone programmable false alarm reduction feature that allows Fire, Supervisory, Auxiliary 1, and Auxiliary 2 zones to be programmed to delay from 1 to 250 seconds. If the zone remains shorted for the entire length of the zone retard delay time, an alarm initiates.
Zone Retard Delay Time
A programmable delay time that can be assigned to Fire, Supervisory, Auxiliary 1, and Auxiliary 2 type zones. The zone retard delay can be programmed from 1 to 250 second increments. See Zone Retard.
Zoned Systems
Identifies the zone area or circuit in where an alarm signal originates. Most modern burglar alarm systems can signal this zone information to the monitoring center.
