8.1.17 Two-stage alarm with initial zone RESET and a coincidence including two fire warning
devices to accelerate a 2
nd
stage alarm (variant #16)
After a fire warning device belonging to a zone is actuated, the control panel waits for 40 seconds
and resets the zone automatically.
If, during 8 minutes from the zone reset, any other device is re-actuated, the control panel generates
a 1
st
stage alarm and the alarming procedure is the same as in variant 2.
Otherwise, if the devices in the zone are not re-actuated within 8 minutes, the control panel treats
the previous actuation as false and returns to the quiescent mode.
Actuation of two or more fire warning devices in this zone results in accelerated generation of a 2
nd
stage alarm.
Note:
Correct operation of this variant requires that at least two (preferably three) fire warning devices are
declared in the zone.
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 2
nd
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 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).
