Activating the alarm delay function
8.1 Introduction
To avoid causing any unnecessary disturbance at particular times of the
day it is possible to disable the immediate alarm warning. By disabling
this function (i.e. when alarm delay is active), a period of 5 minutes will
pass before the sounders start to ring. This facility enables the operator,
for example, to activate an alarm delay during the day and deactivate the
delay function during the night (the D/N function).
IMPORTANT: An alarm from a manual call-point, or alarms from two
or more detectors in the same zone or in two zones, will give immediate
warning on the alarm outputs even though the immediate warning
function is disabled.
The immediate warning function is disabled either direct from the front
panel (see Cap. 8.2) by pressing key 9 + in operator mode, or by
using an auxiliary switch/timer (see Chap. 8.3).
If the alarm delay function is activated from an auxiliary switch, it can
not be deactivated again from the control panel, i.e. the switch has
priority over the key-code.
In an alarm situation, an alarm delay can be overridden manually by
operating the nearest manual call-point in one of the zones.
NB!
The function will automatically be restored after a 12-hours time lapse,
This safety function applies to both front panel or auxiliary switch
disablement.
