A partial zone disablement, with programmed alarm variant higher than the second one, causes that
this zone variant is automatically replaced with the immediate one (variant 1). After the zone
complete re-enablement, the initially programmed variant recurs.
8.4.2 PK relays disablement/re-enablement
The PK relays disablement/re-enablement is accomplished in the RELAYS DISABLEMENT option. The
PK relay disablement brings switching off an appropriate relay regardless of the control panel state.
8.4.3 LS signalling lines disablement/re-enablement
The LS signalling lines disablement/re-enablement is executed in the SIGNALLING LINES
DISABLEMENT option as a logical device. The LS line disablement results in an interruption of fault
signalling. After a re-enablement, unless the fault is removed, signalling appears again.
8.4.4 LK monitoring lines disablement/re-enablement
The LK monitoring lines disablement/re-enablement is executed in the MONITORING LINES
DISABLEMENT option as a logical device. The LK line disablement results in an interruption of fault
signalling or technical alarm signalling. After a re-enablement, unless the fault or technical alarm is
removed, signalling appears again.
8.4.5 EKS-4001 monitoring and controlling elements disablement/re-enablement
The EKS-4001 monitoring and controlling elements disablement/re-enablement is accomplished in
the EKS ELEMENTS DISABLEMENT option as logical devices. The EKS disablement produces switching
off the output relay and the element fault signalling or technical alarm signalling interruption. After a
re-enablement, unless the fault or technical alarm is removed, signalling is restored.
8.4.6 EWS-4001 multi-output controlling elements disablement/re-enablement
The EWS-4001 controlling elements disablement/re-enablement is achieved in the EWS ELEMENTS
DISABLEMENT option as logical devices. The EWS disablement results in switching off the output
relay and an interruption of the output fault signalling. After a re-enablement, unless the fault is
removed, signalling is restored.
8.4.7 EWK-4001 multi-input monitoring elements disablement/re-enablement
The EWK-4001 monitoring elements disablement/re-enablement is executed in the EWK ELEMENT
DISABLEMENT option as a logical device. The EWK disablement results in switching the input off,
what induces that no signal from this input are received, and the fault or technical alarm signalling is
interrupted. After a re-enablement, the control panel indicate the current status of this input.
8.4.8 SAL-4001 acoustic signalling devices disablement/re-enablement
The SAL-4001 acoustic signalling disablement/re-enablement is executed in the SAL ELEMENT
DISABLEMENT option as a logical device. The SAL disablement results in switching off the SAL
signalling and a fault signalling interruption. After a re-enablement, unless the fault is removed, the
fault signalling is restored.
8.5 EVENT AND ALARM MEMORY
8.5.1 Event memory
The POLON 4900 control panel may store 2,000 last events in its non-volatile memory. Each event is
accompanied by a description, date and time of occurrence (accuracy up to 1 second). The events
stored in the memory in chronological order include:
