The above illustration shows the normal sequence of an alarm as well as early acknowledgement and the
switching of the system back into the alert state through the Manual Armouring option:
t
1
: When the Master Generator is switched on, the alarm system becomes alert through activation (once) of
the Manual Armouring function.
t
2
: An alarm contact is activated, eg by the opening of a secured port. Since the armouring delay T
FV
in this
example has not yet elapsed, nothing happens at first.
t
3
: After elapse of the armouring delay T
FV,
the alarm is started, ie both the channel of the alarm contact and
that of the Manual Armouring start to flash.
t
4
: After elapse of the de-armouring delay T
AV
, the Master Generator activates the alarm siren.
t
5
: After elapse of the siren time T
A
, the alarm siren channel is deactivated. The flashing of the alarm contact
and the Manual Armouring output continues.
t
6
: After elapse of the alarm signal delay T
M
set at the object “Alarm signal”, the channel is briefly activated. At
the same time, the alarm contact is continuously switched off and the Manual Armouring output continuously
switched on.
