Disabling system elements
Zones, sensors, call points, sounders, control outputs, outputs, and remote
manned centre alarms can be manually disabled for maintenance or other
purposes. When disabled, the condition reports on the ZP3 panel as described in
Table 11 below. Disablement is normally carried out by maintenance personnel,
and can only be done by personnel with a level 2 access (or higher). In certain
cases, where a specific part of a system is regularly disabled at certain times (for
example, a meeting room which allows smoking), the system is sometimes set
up to allow the operator to carry out the disablement, usually with a key switch.
