4.9 Disablement and Enablement

It is possible to disable an individual device (see
Section 4.9.1), a complete zone (see Section 4.9.2) or
all outputs (see Section 4.9.3).
[This function is also possible from a remote switch (see
Section 4.9.4) or configured using the time-of-day
function (see Section 4.9.5)]. Use of time-of-day for
disablement is not allowed under EN54.
If a device is disabled, then although its conditions
continue to be monitored a detected FIRE condition does
not lead to Fire Alarm actions being taken. The primary
purpose of disabling a sensor is to avoid unwanted alarms
of FIRE where exceptional circumstances prevail. In
addition certain FAULTs (in particular device missing and
low data reading) do not lead to normal Fault action being
taken.
If a Control module or sounder is disabled, it does not
activate in the event of an Alarm or Evacuate operation,
even if the Control Matrix specifies that it is required to
do so.
There is normally no time-out for disabled devices; the
disablement is effectively permanent until cancelled by
a subsequent enablement operation. Some systems,
however, may be configured so that disablement (see
Section 4.9.1) is automatically cancelled after a set time-
out or at certain times of the day (non-EN54 compliant).
See the ID2000 Series Panel Configuration Manual
(997-435-XXX) for more details.
Note: You cannot have two or more sets of zones set to
different time-of-day schedules.
The following indications are given if a device is disabled:
a. The lamp indication [DISABLEMENT lamp, and
SOUNDERS DISABLED lamp (if appropriate) and
ZONE lamp (if appropriate)] and displayed status
message DEVICES DISABLED (in the absence of
any current FIREs, FAULTs, etc.) show whether any
devices are disabled on the system as a whole.
b. The fault buzzer sounds intermittently (every
2 minutes or as configured). This mode cannot be
completely silenced even by pressing RESET.
