Disabling devices, sounders, etc.

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 7. 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 setup to allow the operator to carry out the
disablement, usually with a key-switch.

Table 8: Disabling devices, sounders - types of disablement

Category Description
Devices These are input devices such as zones, sensors, manual breakglass call points, etc. Provided
the number of devices is sufficiently small, and the relevant staff are aware of the situation
and keeping it under control, this situation is usually considered acceptable.
Sounders and RMC Disabling of sounders or the remote manned centre alarms is considered very serious, and
some authorities do not approve of this practice. If sounders are disabled for any reason,
they must be re-enabled as soon as possible.

Operator action

Press the Disabled button to view disabled zones. The screen shows disabled or partly-disabled
zones; scroll with the up/down More buttons to view all. Status LED indicators indicate the
category of devices which are disabled.
If a fire alarm occurs while sounders are disabled, press the Restore Disabled Alarms button.
This restores any disabled sounders.
