8.1.18 One-stage alarm with temporary zone dis-actuation (variant #17)
Actuation of a fire warning device in a zone during control panel operation in the PERSONNEL ABSENT
mode (the PERSONNEL ABSENT diode is lit) results in generating a 2
nd
stage alarm. When the control
panel operates in the PERSONNEL PRESENT mode (the PERSONNEL ABSENT diode is off), the zone is
automatically dis-actuated (fire warning devices are not visible to the control panel).
8.1.19 Alarm with a manual call point (ROP)
After the ROP-4001M or ROP-4001MH manual call points is actuated, the control panel immediately
generates a 2nd stage alarm, regardless of the variant programmed in the zone to which the manual call
point is assigned.
8.1.20 Alarming in the "DELAYS OFF" mode
In the "DELAYS OFF" mode, the control panel does not introduce any delays of given outputs actuation.
The T1, T2 and T3 time is reset so two-stage alarm changes into appropriate one-stage alarm. However,
the lack of delays does not result in removing any coincidental variants or variants with initial reset (in
these variants two-stage alarm is replaced with one-stage alarm).
The "DELAYS OFF" mode also results in zeroing delays for PK relays and LS potential outputs.
Note:
The "DELAYS OFF" mode does not reset the delays programmed directly in the EKS-4001 element by
means of the "OPERATION MODE" option.
8.1.21 Alarming in the "PERSONNEL ABSENT" mode
The alarming variants aimed at eliminating false alarms require the operating personnel's co-operation.
These variants are useless if an operator is not present by the control panel. In such cases, programming
any delays in informing the responsible service about a fire is not advisable. To this end, it is possible to
switch the control panel operation mode into PERSONNEL ABSENT, which will result in the fact that the
alarming variants for all zones (apart from the fire extinguishing zones 1 ÷ 4) are automatically changed
into standard one-stage alarm (variant 1) or, in the case of interactive variants, they are changed into
one-stage interactive alarm (variant 9).
This rule does not include 1 ÷ 4 fire extinguishing zones which retain the programmed alarming
variant in each control panel operation mode.
The operation mode is switched after pressing the PERSONNEL ABSENT push button (the diode located
in this push button is lit). Changing the control panel operation mode is possible with at least 2
nd
access
level.
The operation mode is automatically switched to PERSONNEL ABSENT when one of the four times for
automatic operation mode switching into the PERSONNEL ABSENT is programmed.
The operation mode is switched to PERSONNEL PRESENT after pressing the PERSONNEL ABSENT push
button again (the diode located in this push button is off). The programmed alarming variants are
restored to all zones.
8.2 FAULTS SIGNALLING
Thanks to its internal self-monitoring systems, the POLON 4500 control panel detects and signals faults
in detection lines and in the control panel.
Any detected fault is signalled optically and acoustically. Faults are signalled optically by steady light of
the yellow collective FAULT diode and acoustically by a slow intermittent signal of constant frequency.
