Inhibit and isolate

A faulty device can be inhibited or isolated.

Inhibit

A zone is inhibited from indicating normal or active status. It becomes excluded
from functioning as part of the system for particular time. However, tampers are
still monitored.
The zone is inhibited until the next unset.
A zone can be inhibited automatically when using the forced set functionality. It is
configured via menu "8.4.4 Forced set" on page 244 in Chapter 5 "Menu
reference".

Isolate

A zone or a bus device is inhibited from indicating normal or active status. It is
excluded from functioning as part of the system permanently, until de-isolating by
the manager or installer.

Zone shunt

A shunt procedure inhibits zones, when active, from generating an alarm during a
certain time period.
A zone can be shunted in the following ways:
• Manually by the installer. Use menu "1.2.1.9 Shunt zones" on page 124.
• By a schedule. See "Calendar" on page 77 for details.
• By a conditional filter. See "Condition filters" on page 74 for details.
• By a zone with Shunt type. See "Zone types" on page 45 for details.
Caution:
There is a limitation of the number of zones that can be shunted
simultaneously. The limit is set in "4.2.n.7.3 Shunt limit" on page 190.
During the shunt time the zone is inhibited.
If the zone is still active after the shunt time has expired, the zone will generate
an alarm, depending on the zone type and the status of the area.
For particular users (depending on their user options) the shunt is active during
an extended shunt time.
Before the shunt timer expires, a warning may be given.
