8.3.6 Line elements location
The control panel enables its users to physically inspect the line element location through alternate
actuation of the red and yellow LEDs of the element. This testing procedure is described in the
programming manual (PM).
8.3.7 MSG-45 modules testing
See chapter 9 for MSG-45 module testing procedures.
8.4 SYSTEM ELEMENTS DISABLEMENT/RE-ENABLEMENT
The control panel program makes it possible to disable line elements, zones, control panel
outputs/inputs or executive line elements.
The fact that an element is disabled is signalled by the control panel with the steady light of the yellow
collective DISABLEMENT diode.
An element may be disabled/re-enabled by operators at the 2
nd
or higher access level authorisation.
8.4.1 Fire warning devices and zones disablement/re-enablement
In case fire warning devices are faulty or repair works are executed in the protected facility (which may
result in generating false alarms), the control panel makes it possible to disconnect monitoring for a
given section of the facility through disablement of the whole zone or its part as required.
The FIRE WARNING DEVICE DISABLEMENT option is used to disable/re-enable fire warning devices.
A part of a zone may be disabled/re-enabled by disablement of individual addressable elements in the
zone. The whole zone may be disabled/re-enabled in a simpler way, i.e. by carrying out the above
activity within the whole zone using the ZONE DISABLEMENT option.
Disablement of fire warning devices or the whole zone results in the fact that the control panel does not
receive alarm and fault information from the disabled line elements and automatically restore the
possible fault signalling within the zone. If the fault is not removed, the fault signalling is restored, after
the zone is re-enabled.
Partial disablement of a zone with a programmed alarming variant higher than the other one, results in
the fact that the variant for this zone is automatically changed into the immediate operation variant
(variant 1). After the zone is fully re-enabled, the previously programmed variant is restored.
8.4.2 PK relays disablement/re-enablement
The PK relays may be disabled/re-enabled in the RELAY DISABLEMENT option. If a PK relay is disabled, a
given relay is disabled, regardless of the control panel condition.
8.4.3 LS signalling lines disablement/re-enablement
The LS signalling lines may be disabled/re-enabled as logical devices in the SIGNALLING LINE
DISABLEMENT option. After an LS line is disabled, a fault is no longer signalled. If the fault is not
removed, the fault signalling is restored, after the line is re-enabled.
8.4.4 LK monitoring lines disablement/re-enablement
The LK monitoring lines may be disabled/re-enabled as logical devices in the MONITORING LINE
DISABLEMENT option. If an LK line is disabled, faults and technical alarms for this line are no longer
