7.3 ATD checkback input fault:
For remote alarming, alarming by means of an alarm transmission device (telephone dialling device), for example, to a
mobile telephone or to a property security company can be raised additionally or as an alternative (for example, for a
silent alarm) to activate the local alarm indicators an
(refer to "6. Alarming", page 50)
.
However, it may happen that there is a fault or defect in the alarm transmission device, or that the telephone line is busy.
In such case, the alarm transmission device cannot transmit the remote alarm. The alarm transmission device can inform
the alarm central unit of such unsuccessful alarming. For this purpose, the "ÜG-R" wired (checkback) input in the alarm
central unit and/or the "ATD checkback input fault" EIB object is available.
If the alarm central unit detects a signalled fault at one of these inputs it will generate a 'global' fault signal.
In the event of an intruder alarm within an area or of an attack alarm, such fault signal can be interpreted as unsuccessful
alarming. In this connection, an alarm can be raised subsequently or again for the preset alarm period by the local alarm
indicators (flashlight, indoor or outdoor siren). You can separately parameterize for both types of alarming (in the "ATD
checkback input response to intruder signal to the ATD" or "ATD checkback input response to attack signal to the ATD"
parameter branch) through which local alarm indicators you want to raise alarms.
A fault in the alarm transmission device in the event of an intruder alarm will only be evaluated if alarming through the
alarm transmission device has, in principle, been enabled in the area concerned

8. Detector Test
To test the functioning of all detectors installed in the various safeguarding areas the detector test mode is available.
By activating the detector test mode ("detector test = "1"/messages in the display units: "detector test"), you can acti-
vate or deactivate the following properties of the alarm central unit for the period of the test:
•
The system is passive, i. e. no alarms or faults signals can be raised.
•
Arming will not be possible.
•
No response to 'global' fault signals (mains failure, battery fault, "alarm central unit wired detector sabotage", "alarm cen-
tral unit enclosure sabotage", "ATD checkback contact fault", abortive heartbeat check or current limitation).
•
You should not programme the alarm central unit in this state, nor can you read out the event log.
In the detector test mode, you can view in the display units any tripped or missing detectors (intruder, sabotage, fire or
attack detectors, wired detector input). In this connection, the detectors are sorted by the safeguarding areas (AA 1 to
AA 4, fire detector, attack detector) and are only visible in the displayed areas.
Any detectors once tripped in the detector test mode will remain visible in the display units until you exit the test mode
and need not be acknowledged. The detectors which have tripped in this state and the detector test itself will not be
saved in the event log.
'Global' faults will not lead to system faults during the test. However, such faults will be saved in the event log and will
lead to an alarm central unit fault after you have deactivated the detector test if the reason of the fault still exists when
the detector test is being quitted.
In the detector test mode, you cannot check any arming devices (arming input). Using the alarm reset option will lead
to the deactivation of the detector test.
You can only activate the detector test mode from the "disarmed" state. If the system is in a different state the request
for changeover to the test mode will be ignored and not saved.
If the alarm central unit is in the detector test mode while a bus voltage failure occurs the system will always change
into the "disarmed" state after bus voltage recovery.
After the deactivation of the detector test mode ("detector test = "0" EIB object or using the alarm reset option) all
areas will be in the "disarmed" state. If any fire or attack detectors are active in this state a fire or an attack alarm will
be raised immediately after you have deactivated the detector test. The alarm central unit may also change into the
"fault" state.
