Part 9
As a rule, arming devices also have sabotage contacts. Such contacts can be assigned to the safeguarding areas as
detectors parameterized to "arming device sabotage".
If an arming device is tampered with such device must no longer be authorized to disarm the system. In such case,
the alarm central unit will inhibit all telegrams which have been sent by the bus device 'tampered with' and will raise
an alarm when in the armed state. In the disarmed state, an alarm central unit fault signal will be issued. If you have
parameterized any info display units a sabotage signal from an arming device must first be called into the display
before you can reset the fault signal
(refer to "5. Operating the Alarm Central Unit", page 40).
The assignment of a sabotage detector of an arming device of the corresponding safeguarding area can be done by
the "arming device sabotage input number" parameter in the "arming/arming area X" parameter branch. For this pur-
pose, it is assumed that an "arming device sabotage" detector has been created in the corresponding safeguarding
area
(refer to "3. Detector and Sabotage Inputs", page 28)
. A created "arming device sabotage" detector can only be
linked with an arming device. In a list, the ETS plug-in will automatically suggest which detector inputs will be possible
as arming device sabotage inputs.
Important note:
In systems which only have one arming device and which has been tampered with, you can only reset the fault
signal or disarm the system by an alarm reset.
4.1.2 Connecting options of arming devices
Example 1:
A maximum of four independent arming devices per arming area (I - IV).
For this purpose, it is assumed that all arming devices have been connected through bus devices, each of them hav-
ing a different physical address.
Such circuitry is recommended, for this will be the only way to enable the alarm central unit to clearly distinguish
among the individual arming devices. If one of the devices has been tampered with you can still use the remaining
arming devices for disarming.
