13 Fire Door Closing Function
Programmable outputs can be used for fire door closing. A special trigger condition is
available (Fire Door Closing.). Type of output is normally "Control, neutral".
One or more alarm points can control the output, i.e. the detectors on both sides of the fire
door as shown in the figure below.
In case of one of the following events, the output will be "activated" and the fire door will
close:
 Fire alarm (from any of the detectors controlling the fire door)
 "Test mode" (the zone involved set in test mode)
 Fault (i.e. "no answer" from any of the detectors

controlling the fire door)
 Disablement (any of the detectors controlling the fire door or the involved zone.
 A definite time every day, if programmed via EBLWin. (The output will be activated
for 20 seconds.)
 Via a programmable input (trigger condition trigger condition no. 9 = Door Closing
Test Input). The output will be activated for 20 seconds.
Note: For safety reasons, an I/O unit 3361 output should not be used. If a short circuit or
double break exists on the COM loop, the I/O unit cannot be forced to activate the output,
i.e. the door will not be closed.
If a magnet contact is available, it is possible to get a "closed fire door verification" via the
Interlocking function. In this case, Type of input / output has to be "Interlocking in-/output".
See also chapter Interlocking Function, page 94.

E.g. a faulty detector, two breaks or short-circuit on the COM loop.
