Control and
monitoring unit
Valid from week of manufacture 40/2012.
Software version 3.0
Description
The SUSB is a control and monitoring unit
designed to control various types of fire/smoke
dampers and fans in a flexible way. The SUSB
is based on a modern powerful
microprocessor, so it can meet all the
requirements of a building installation.

Maximum configuration.
Up to four actuators (dampers) can be
connected in 2 groups. The distribution
between groups can be 2+2 or 3+1. Expansion
units can be installed for an unlimited number
of dampers, although they will all be
controlled by the same function. In principle,
any number of smoke detectors can be
connected, but the number is often limited by
the difficulty in maintaining this kind of
solution. Detectors can be connected to the
SUSB via two separate loops. An external
monitoring unit can also be connected.

The 8 modes
The SUSB is designed to handle fire/smoke
dampers in normal ventilation systems and fire
ventilation systems, either independently or in
combination. In the event of fire, the
ventilation system must usually be stopped and
the fire ventilation system started. It must also
be possible to move the dampers in different
directions depending on the function. There is
a choice of eight different modes. Valid from
serial number: 0452801.3
Mode 1.
(Jumpers B, C, D OFF)
Used to control up to two fire/
Smoke dampers from two smoke detector
loops while locking two fans. The entire unit
can be thought of as duplicating the function
so that two fire zones can be handled. The
function test is adjusted so that both groups are
tested separately but are started at the same
time. Night mode affects both zones, including
all dampers and fans.

Page. 3
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

Page. 4
if the dampers have moved to the open
position. Fan 1 is stopped in the function test.
After 30 seconds the dampers move to the
open position. (The 30-second delay can be
removed by setting jumper E.) Every 16th test
sequence (once a month) the fire ventilation
fan (Fan 2) starts running and continues until
channel 1 of the clock is closed. When the
clock opens, Fan 2 stops, the dampers close
and Fan 1 starts. In the other 15 test cases, Fan
2 does not start, regardless of how the timer is
programmed. Immediately after the dampers
are opened, they are closed and returned to the
normal position.
Function test during night mode.
In night mode, the function test can be run
without special programming. The SUSB
detects the damper positions and carries out
the function test in the other direction. The
fans are only affected if they are fire
ventilation fans.
Priority.
If an alarm (triggered detector or external fire
alarm) is received during the function test, the
test is ended and the unit immediately switches
to alarm state.
Fan control
Intelligent and integrated fan control is
provided. There are two fan control outputs
that are used differently in the 8 modes.
If the ventilation system is connected, the fan
receives the stop signal as soon as smoke is
detected. For controlled, non-acute operation,
for example in a function test, the fan is given
30 seconds to reduce its speed before any
damper is closed.
The fire ventilation fans can be controlled
from 1 or 2 outputs on the SUSB. If two fans
are connected, they are started with a 10
second interval if a detector is triggered. In a
function test, the interval is 30 seconds. This
prevents an unnecessarily high starting current
if both fans start simultaneously.
Functional Testing of Smoke with
pressure sensor.
If Smoke Evacuation Fan is provided with
a pressure sensor it can be connected to
terminal 1and 2 in SUSB. After starting the
Smoke Evacuation Fan by relay output fan
1 or fan 2 (depends on the selected
operating mode) in SUSB the pressure
sensor must provide an closed contact
within 30 seconds otherwise SUSB will
indicate Functional test fault and Summary
alarm. If no pressure sensor is connected
the terminal 1,2 must be bridged.
The clock.
The control clock controls a function test, if
there is one. In modes 4, 5, 6 and 7, the fire
ventilation system can be tested for the on time
programmed in the clock. 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. ON at the
clock means the start of the test. OFF means
the end of the test. The clock automatically
switches between summer/winter time and is
preset for a function test at 01:00 on Sunday.
Installation.
230 V 50 Hz
Must be connected via fixed cables to a group
fuse of at least 2A. The isolating switch must
be positioned close to the unit. The SUSB is
built with reinforced insulation, so no ground
is necessary.
Relay outputs
All relays are shown in the open position. Fans
1 and 2 are normally activated (mode 3). In an
alarm, the summary alarm is activated and 10-
12 closes for example.
Damper connection
Fire/smoke dampers are connected as shown in
the diagram below.
If evacuation dampers are used, they must be
connected with Ö and S reversed compared to
the figure above. Evacuation dampers are
normally closed, and are opened if there is an
alarm. The damper motor closes the damper
and the spring return opens it. This only
applies to modes 4, 5, 6, 7 and 8.

Connection of external units. N.B. Connection wires of older belimo was S1, S2, S3 and so on.
Corresponding marking are 1,2,3 and so on in the drawing above. Drawing is in power off condition.
Smoke detector inputs
The two smoke detector inputs are designed
for a loop resistance of 2200 ohm (terminating
resistor). Depending on the selected mode, one
or both detector circuits are connected. If the
mode selected has both circuits active, unused
detector inputs are terminated with a resistor
connected directly to the terminal. 2200 ohm,
power at least 0.6W. See also the description
of the modes.
Expansion unit
Terminals 20-21-22 are used to connect an
expansion unit. A connection drawing can be
found in the documentation for the expansion
unit. Dampers forming part of damper group 1
can be connected to the expansion unit. No
expansion unit can be connected to damper
group 2.
Cable type for connections
The smoke detectors are connected with
twisted-pair cable separated from other parts.
Telephone type cable is used, with no
particular requirements in terms of area.
For example, the actuator can be connected
with EKKX 1*4*0.5 if the distance between
the actuator and the SUSB is less than 100
metres. If the distance is greater, a larger area
is required, especially for the G wire but also
for M. DC resistance must not exceed 8 ohm.

Fuses
There is a 160 mAT fuse on the motherboard.
To access the fuse, remove the four screws in
the corners of the front panel. Carefully place
the panel to one side – there is a fuse holder at
the bottom right. This is the primary fuse.
A self-healing electronic fuse is provided as a
secondary fuse to protect the damper motors,
etc. If this fuse is tripped, it resets
automatically if the SUSB is switched off for
five minutes.

Time-switch
The time switch is used for automatic tests of
damper and Smoke Evacuation fans. The time
switch has a battery backup, which will secure
approx six years operation without mains
voltage. To save energy the time-switch uses a
so-called sleep-mode i.e. the display will be
deactivated if it has been idle for 15 minutes.
The display will be activated again by pressing
any of the buttons.
The time switch is pre-set at delivery. It is
programmed to start the test at 1 AM on
Sundays.
Settings
If RES-button is pressed (by using a pointed
object and pressing the button for 1 second) or
if the battery is changed during power failure,
the watch will be reset but all programmed
times will remain.
•Follow the instructions in the time-switch
menu. Language, year, month, day and time
has to be re-entered.
Menu overview.
Deletion of programmed values
It is possible to delete the different program
steps, either in single steps or the whole
program. If a program is deleted, the
programming of the pulse is also deleted. This
is self-explanatory as you step through the
menu.

Graphic of programming.
Manual control of the automatic functions
The test cycle will be stared automatically by
pressing the "+ and "-" buttons simultaneously
twice. The dampers will close and the green diode
indicating open damper will switch off on the
monitoring and control unit. After a few minutes
the dampers will open and all green LED:s should
indicate open damper. This will be reversed in the
case of evacuation dampers.
The manual function need to be switched off
for normal operation. Check that it is in the
OFF position. If not press the "+ and "-"
buttons simultaneously. In order to control the
clock to work, this manual function is usually
not used. If you press the left and right button
simultaneous for 2 seconds, the output of the
clock will be set permanently ON or OFF.
This function overrides the programmed time.

Indicators and buttons
A Dampers
Green or red LED indicates open or closed
dampers respectively
The damper groups are numbered 1 and 2.
B Fans
The two fan controls are indicated with
separate LEDs, which light when the relevant
relay is closed.
See the relevant mode for the function of both
fan control outputs.
C Smoke detectors
The two smoke detector loops are indicated
with different patterns using the same set of
LEDs.
Detector 1 is indicated with the following
pattern: on 0.1 seconds off 0.9 seconds
Detector 2 is indicated as follows: on 0.9
seconds off 0.1 seconds.
If both detectors are indicated or if the EXT
input is used for an external monitoring unit
and alarms, the LEDs are constantly lit.
Alarm
Red LED indicates:
•Smoke detector triggered.
•EXT input activated.
Service
Yellow LED indicates that the connected
smoke detectors are dirty. The smoke detector
has a yellow LED, which lights with the
service alarm. The indication is delayed by one
hour to prevent false alarms. When the alarm
is reset, the delay is deactivated to make it
possible to confirm immediately that the alarm
has been cleared.
Error
Red LED indicating a break in the detector
loop. If there is a break, the dampers and fan
are stopped in modes 1-3 and modes 6 and 7.
The function is the same as if a detector
indicates smoke, but the alarm LED does not
light.
The patterns used to determine which of the
two loops is faulty are the same as for service
alarms.
D Weekly timer switch
The control clock is for the function test time.
E Summary alarm
The summary alarm is indicated by the red
LED and the associated relay output is closed
when the following events occur:
•Smoke detector 1 or 2 triggered.
•EXT input activated. (Jumper F=OFF)
•Break in any of the cable loops.
•Error during function test.
•Service alarm in any of the detector loops.
•Damper in incorrect position during normal
operation.
F. Function test error.
The LED shows that the function test has not
completed successfully. The following are
tested for errors.
•The dampers in both damper groups close
within 30 seconds.
•The actuator contacts are correctly closed
with the dampers in the closed position.
•The dampers open within 200 seconds.
•The actuator contacts are closed with the
damper in the open position.
G. Operation
Green LED showing that the unit is receiving
power and indicating day/night mode.
Constant = day mode. Flashing = night mode.
H. Reset
Button to reset the entire alarm. While the
button is pressed, the detector outputs are
disconnected to allow any triggered smoke
detectors to be reset.
I. Manual test
Press the button to start the function test
according to the defined mode. This function

Page. 10
requires that clock channel 1 is not active.
OFF must appear in the clock window. The
function test is limited in modes 4, 5, 6, 7 and
8 because the fire ventilation fan does not start
unless the button is held down for at least 1.5
minutes. (The function test normally uses the
clock if there is one)
Description of jumpers.
The jumper panel is in the connection area on
the left.
AExcludes fan locking in external night
mode. (Only from serial numbers ending in
1.4)
BSelects the operating mode, together
with C and D.
CSelects the operating mode, together
with C and D.
DSelects the operating mode, together
with B and C.
E=ON means that the fans are not
stopped for a function test. Use this
setting if the unit is operating at the
periphery of a ventilation system. Only
affects the ventilation system, not fire
ventilation. Only active in modes 1, 2,
3, 6 and 7. Note that high pressure can
build up in the duct system if this
jumper is on if the monitored/controlled
dampers are located in the main duct. In
mode 8, the jumper is used to suppress
the 30-second delay in order reliably
stop the fan in the function test.
F=ON means 0second delay before
dampers are closing in Night mode or
test.
G=ON means 5 minutes delay before
dampers are closing in Night mode or
test.
H=ON means automatic reset when input
5,6 is closing.
