report actuation, the control panel generates a 1
st
stage alarm and the alarming procedure is the
same as in variant 2.
Otherwise, after 8 minutes, the control panel resets the preliminary alarm mode treating the devices
actuation as false and returns to the quiescent mode.
Note:
Correct operation of this variant requires that one (preferably two) fire warning device is declared
both for group A and group B. Such created groups must not be separated with any physical
obstacles. Failure to meet the above-mentioned requirements may result in constant cancellation of
the alarming device.
8.1.14 Two-stage alarm with a group-time coincidence to accelerate a 2
nd
stage alarm (variant #13)
After a fire warning device belonging either to group A or group B is actuated, the control panel
generates a 1
st
stage alarm and the alarming procedure is the same as in variant 2.
Simultaneous actuation (coincidence) of fire warning devices from both groups results in immediate
generation of a 2
nd
stage alarm.
Note:
Correct operation of this variant requires that one (preferably two) fire warning device is declared
both for group A and group B. Such created groups must not be separated with any physical
obstacles.
8.1.15 Two-stage alarm with initial zone reset and a group coincidence to accelerate a 2
nd
stage
alarm (variant #14)
After a fire warning device belonging to a zone is actuated, the control panel waits for 40 seconds
and cancels 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.
Simultaneous actuation (coincidence) of fire warning devices from both groups results in immediate
generation of a 2
nd
stage alarm.
Note:
Correct operation of this variant requires that one (preferably two) fire warning device is declared
both for group A and group B. Such created groups must not be separated with any physical
obstacles.
8.1.16 Two-stage alarm with a coincidence including two fire warning devices to accelerate a 2
nd
stage alarm (variant #15)
After a fire warning device belonging to a zone is actuated, the control panel generates the
1
st
stage alarm and the alarming procedure is the same as in variant 2.
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.
