4.2.4.12.3 Arming
Arming/unarming the security areas
The signalling system makes a distinction between security areas, the interior and the external
skin. This distinction allows separate monitoring and arming of different building sections depending
on whether authorised people are in them or not. For this reason, the panel allows internal
and external arming (see chapter 4.2.4.12.1. Introduction and basic principles).
A security area can only be armed when all the detectors assigned to this area are inactive and
there is no fault in the system. The status of the signalling system and the individual security
areas is always displayed on the system page of the signalling system (see picture 35).
Arming and unarming takes place either directly on the panel or using KNX/EIB switching units,
such as button sensors or button interfaces or keyswitches connected to binary inputs. There
are also two separate 1 bit communication objects available for arming the bus, one for internal
arming and one for external arming. The telegram polarity of these objects is fixed:
"1" = Arm / "0" = Unarm.
Arming can take place on the panel using the "Arm" and "Unarm" buttons on the system page of
the signalling system. The panel automatically switches the function (Arm / Unarm) according to
the current system status. Local arming using the buttons can be prevented in the parameter
configuration of the ETS plug-in by hiding the buttons.
Arming without arming delay:
The area to be armed must be ready for arming. On internal arming, the signalling system only
tests the external skin whilst on external arming, both the internal skin and the interior are tested
for arming readiness. The detector list helps the system operator to detect active detectors
which prevent arming readiness.
Pressing the "Arm" button on the panel" or a "1" telegram to the "Internally armed" or "Externally
armed" object causes the system to switch to the "Armed" status immediately.
Arming with an arming delay:
Arming with an arming delay is often used when the switching device
(e.g. the panel or a button sensor) is installed in the secure area of the building. In this case, the
system operator must be able to arm the system and still be able to leave the building in time.
The arming delay can be configured separately, using the parameter of the same name in the
ETS plug-in, for internal and external arming. Delay times of 0 s to 255 s can be configured. The
setting "0 s" (presetting) deactivates the arming delay for the appropriate arming operation.
When setting the time, a time reserve should be planned, so that the user is still able to leave
the building to be secured correctly before actual arming.
The delay time specifies after what time after a arming command (turning of the keyswitch or
pressing of the "Arm" button on the panel) the system is actually armed. In so doing the signalling
system only checks the arming readiness of the security areas after the delay time has
elapsed.
Example: the system is to be armed externally on the panel. For external arming, the system
operator must leave the building. The front door is still open. Therefore, the panel displays "not
ready". However, the operator can still carry out the arming command on the panel. The panel
starts the arming delay. Within this time, the owner leaves the building and locks the front door.
This makes the system ready for arming (no more detectors are active). When the delay time
has elapsed, the signalling system checks for the arming readiness system status. If it is ready,
the system arms immediately.
Should, however, a detector still be active at the end of the arming delay, (e.g. front door not
closed or window opened), then arming does not take place. Here too, the detector list helps the
system operator to detect active detectors which prevent arming readiness before setting the
arming command. If the system does not arm after the delay time has elapsed, then no acknowledgement
will take place either (see next section).
i An elapsing arming delay can be cancelled at any time by unarming.
