Mode 2.
(Jumper B ON)
One fire zone is handled via one detector loop,
and up to four fire dampers in one group.
Detector 2, damper 2 and fan lock 2 are not
used. The function test is adapted. Night mode
affects all dampers and the fan.
Mode 3.
(Jumper C ON)
This mode works like mode 2 but both
detector loops and both damper inputs are
users. Fan locks 1 and 2 are used, and are
connected in parallel. Valid from serial
numbers ending in 1.5. The unused detector
input must be terminated with a 2200 ohm 1 W
resistor.
Mode 4.
(Jumpers B and C ON)
Intended for fire ventilation. The two zones
are handled separately. When one of the
detector loops signals an alarm, the dampers
are opened and the relevant fire ventilation fan
is started. If smoke is detected by the other
detector circuit, the damper in that group is
moved immediately, but there is a 10 second
delay before the fan starts. This delay is only
active if a start signal is received from both the
detector loops at the same time. This feature
means that large fire ventilation fans are never
started simultaneously, simplifying
dimensioning of the electricity network. The
function test involves opening the dampers,
starting the fans 30 seconds later, then
continuing the test until the end of the
programmed test time. The system then returns
to normal mode. From serial number
9020811.2, the fan test can be skipped by
programming the control timer with a test time
of 1 minute. This prevents the fire ventilation
fans ever starting. Night mode has no effect in
this mode.
Mode 5.
(Jumper D ON)
Same as mode 4 but the fans are function
tested once a month. The dampers are function
tested as usual, every 48 hours unless specified
otherwise.
Mode 6.
(Jumpers B and D ON)
Combination mode. Damper group 1 is used
for fire/smoke dampers and for locking the
ventilation system for fan 1. Damper group 2
is used for evacuation dampers and the fire
ventilation fan is connected to fan 2. The
detector inputs are linked and must be
connected. The unused detector input is
terminated with a 2200 ohm 1 W resistor.
Damper group 1 is used for dampers that are to
be closed when a detector is triggered. Damper
group 2 is used for dampers that are to be
opened when a detector is triggered. Fan 1 is
stopped when a detector is triggered, and fan 2
is started. The function test involves closing
the fire damper, opening the evacuation
damper, locking the ventilation system and
starting the fire ventilation fan. The test ends
when the programmed time is reached. Night
mode only affects damper group 1 and fan 1.
The function test in night mode involves
opening the evacuation damper, opening the
fire damper, closing the fire damper and
starting the fire ventilation fan, and continues
to the end of the test time. The fire ventilation
fan is then stopped and the evacuation damper
is closed. From serial number 9020811.2, the
fire ventilation fan test can be skipped by
programming the control timer with a test time
of 1 minute. This prevents the fire ventilation
fans ever starting.
Mode 7.
(Jumpers C and D ON)
Same as mode 4 but fan 2 (fire ventilation fan)
is function tested once a month. The dampers
are function tested as usual, every 48 hours
unless specified otherwise.
Mode 8.
(Jumpers B, C and D ON)
This mode is designed to handle an evacuation
damper and a fire ventilation fan, but a normal
fan output is also provided. Both smoke
detector inputs can be used, but they are linked
to form a zone. The function is as follows: On
start-up, the evacuation dampers move to the
closed position, Fan 1 start. When a detector is
triggered, Fan 1 is stopped and the evacuation
dampers move to the closed position. Fan 2
starts 10 seconds after smoke is detected even
