4.2.4.12.5 Fault
Cause of fault and fault behaviour
The signalling system switches to the "Fault" status when the sabotage detector has tripped in
unarmed or if, during detector monitoring while unarmed, at least one missing detector was detected.
If the system is armed, then these events will lead to an immediate alarm. In this case,
the system will switch to the "Fault" status, when the alarm has been acknowledged.
A fault restricts the function of the signalling system to such an extent that proper operation can
no longer be guaranteed. A fault causes the system to no longer be armed for as long as the
fault has not been eliminated. The detector list and the event memory can be used to detect the
cause of the fault and the time the fault was activated.
If there is a system fault, the panel transmits a "1" telegram via the "Fault" object. This allows
any switching function to be executed in the bus along with other signalling operations, e.g. using
a transmission device. An -email, predefined in the panel, can be set by linking this object
with an e-mail event (see chapter 4.2.4.13.1. Introduction).
If the fault was triggered by a missing detector, the signalling system uses the
14 byte object "Fault detector text" to display the detector text of the faulty detector. If several
detectors are missing, then the detector text of the detector is transmitted which was most recently
detected as missing.
If the fault was triggered by the sabotage detector, then the test "Sabotage" is transmitted to the
bus via the 14 byte object.
The fault status continues to remain active, even if the cause of the fault has already been eliminated.
The status is only reset after the system operator has acknowledged the fault directly on
the panel.
Acknowledgement of a fault message
A fault must always be acknowledged directly on the panel. Without a fault acknowledgement, it
is not possible to switch back to "Unarmed" status and thus additional arming. The cause of the
fault must have been eliminated in order to be able to acknowledge a fault. This means that the
sabotage detector may ot be active before acknowledgement, ad all the detectors of the security
areas must have been detected as existing. The detector list can be used to detect which detectors
may be preventing the acknowledgement of a fault.
After the operator has acknowledged a fault, the panel uses the "Fault" object to transmit a
"0" telegram and, via the 14 byte object "Fault detector text", the text "No fault" to the bus. After
this, the signalling is system is ready for operation again.
i After an alarm has been acknowledged, the system automatically switches to the "Fault"
status, if, for example, the sabotage input was the detector triggering the alarm. This subsequent
fault must then be acknowledged separately on the panel in the manner described.
