SYSTEM OVERVIEW
The SMOKE MASTER SMPA is an all-inclusive total solution for exit route
Control unit pressurisation. The system has been designed and the com-
ponents constructed to meet the EN 12101-6 requirements. The system
has been subjected to a variety of tests at FläktGroup’s own laborato-
ries. SMPA has been designed for pressurisation of exit routes of differ-
ent types, such as the stairwells of residential buildings, underground
exit routes, and the exit routes from car parks. The SMPA-1 fan unit is
available with three sizes which makes it suitable for use over a wide
range of air volumes.
Due to its compact structure, the SMPA fan unit (SMPA-1) has small
overall dimensions and, therefore, it is also suitable for a variety of reno-
vation projects. In blocks of flats, the fan unit can be installed in the up-
per or lower part of the stairwell.
An SMPA total solution comprises a smoke hatch integrated into the
encapsulated fan unit, a control panel, and a control unit. The apartment
air release solutions with spindle motors, smoke detectors, and control
units are supplied by our partners.
The distance between the fan unit SMPA-1 and the control unit SMPZ-2
should be less than 15 m.

ELECTRIC INSTALLATIONS
STAIRWELL SMOKE DETECTORS
If the fire indication system of the building is used for alarm indication,
no smoke detectors directly connected to the SMPA system are needed.
RELAY UNIT FOR SMOKE DETECTORS
The stairwell smoke detectors should be wired to the relay unit in the
SMPA control unit. The relay unit monitors the operation of the smoke de-
tectors.
Normal operation: Green LED ”Operation” illuminating.
Service alarm: Yellow LED “Service” illuminating.
• Clean the smoke detector: the yellow LED should start flashing slow-
ly.
• Reset the alarm using the Reset button: the yellow LED should go off.
Error: Yellow LED ”Short circuit” illuminating to indicate detector cable
short circuit.
• Fix the problem: the yellow LED should start flashing slowly.
• Reset the alarm using the Reset button: the yellow LED should go off.
Error: Yellow LED ”Broken line” illuminating to indicate broken detector
cable.
• Fix the problem: the yellow LED should start flashing slowly.
• Reset the alarm using the Reset button: the yellow LED should go off.
Smoke alarm: Red LED ”Smoke alarm” illuminating.
• Reset the alarm using the Reset button: the red LED should go off.
The smoke detectors (FDRC-1-SMIA) allow direct connection to the
SMPA system. There should be stairwell smoke detectors ceiling mount-
ed at each landing, or according to a separate plan. The detectors (max.
32 units) should be connected in series, with a terminator connected to
the last one (see wiring diagrams).
The smoke detectors are supplied with plastic dust covers that should
not be removed until the construction work is completed. Alternatively,
the transmitters can be installed just before taking the system into use.
The smoke detectors are optical and rated at 24 V.
When a smoke detector detects smoke, the red LED on the detector is
lit, and an alarm indication is provided to the control unit. The alarm re-
mains active until reset at the relay unit included in the control unit. If no
stairwell smoke detectors are installed, a 2.2 kohm terminator shall be
connected to the control unit, in place of the indicator.

ELECTRIC INSTALLATIONS
DIFFERENTIAL PRESSURE TRANSMITTER
• The pressure transmitter should be installed in a sheltered place.
The silicone hoses should not exceed 10m in length and should be
shielded or otherwise replaced with pipes.
• Take the + hose to the stairwell and the – hose outdoors. The end
of the outdoor hose should be protected against wind and rain,
however, without disturbing pressure measurement.
• The outdoor hose can be taken through a wall using a wall sleeve
designed for overpressure meters (YM-1 + capped pipe + bend),
available as an accessory.
• The factory setting for the pressure range is 100 Pa. Make sure the
dip switch settings are as shown in the picture.
• The display of the pressure transmitter must be accessible to those
conducting annual inspections.
• The display should be reset once a year. Disconnect the hoses and
open the cover. Press and hold the “Zero” button for five seconds.
• The factory setting for the response time is 2s to ease off pressure
control. The setting can be checked by placing dip switch PJ3 to the
F position.

SYSTEM OPERATION, PRESSURISATION AND FREQUENCY CONVERTER
SYSTEM OPERATION
The components controlling SMPA are:
• the fuses and switches in the power • supply cable for the control
unit
• the fuses, frequency converter, relay unit and hatch opening switch
inside the control unit
• the control panel
• the pressure transmitter
• the smoke detectors
• the safety switches for the fan unit
• external systems, if any.
PRESSURISATION
Starting
• When an SMPA smoke detector becomes activated, pressurisation
starts if the control panel pressurisation switch is in the AUT posi-
tion.
• A pressurisation start signal may also come to the SMPA control
unit from an external system, in which case the pressurisation
switch in the control panel must be in the AUT position.
• The pressurisation switch in the control panel is turned to the MAN
position.
The hatch opens. In about 20 seconds, the fan starts running and blow-
ing air into the building. The frequency converter in the control unit ad-
justs the fan speed according to the differential pressure value meas-
ured by the pressure transmitter and tries to maintain an overpressure
of, for instance, 50 Pa in the stairwell.
Stopping
• Pressurisation activated by an SMPA smoke detector shall be
stopped by resetting the ABAV relay unit inside the SMPA control
unit. There must not be any smoke around the smoke detector any
more.
• Pressurisation activated by an external system shall be stopped
from that system.
• Pressurisation activated from the control panel shall be stopped by
turning the pressurisation switch to the AUT or 0 position.
FREQUENCY CONVERTER
The frequency converter controls the pressure during pressurisation. The
parameters of the frequency converter are set at the factory. A list of
these parameters is attached to this document.
CONTROL PANEL
The frequency converter should always be in the AUTO/ON mode!
PRESSURE CONTROLLER ADJUSTMENT
The pressure controller (PI) has been preadjusted to respond fast but
without oscillation. If the leakage air flow of the building is small and
oscillation occurs, the controller can be adjusted less sensitive by de-
creasing gain (7-33) and extending the integral time (7-34).
7-33 Process PI Proportional Gain
0.00 - 10.00 * 0.01
7-34 Process PI Integral Time
0.10 - 9999 s * 9999 s
ERROR CODE
Read the displayed code and remove the cause of the problem.
RESETTING AFTER AN ERROR
To reset an error that has caused the fan to stop use the back-up fuse
to cut off power to the frequency converter and wait until the display has
gone blank. Then, switch on power again. To reset the error, press the
Reset/OFF key and then the AUTO/ON key.

TESTS AND INSPECTIONS
INITIAL INSPECTION
1. First measures
Turn the control unit fuses to position 1.
Turn the safety switches to position 1.
Turn the control panel switch to position 0.
Switch on power to the control unit.
Reset the pressure transmitter to read 0 Pa.
The differential pressure transmitter must be switched on approx. 15
minutes before resetting.
Check that only the green “Operation” LED on the relay unit is on.
Check that the frequency converter is in the Auto/On mode and does
not display any error messages.
The yellow “Service” LED on the control panel should now be on.
Turn the PRESSURISATION switch on the control panel to the AUT po-
sition. The green STANDBY light should now come on.
2. Checking the operation of the hatch
To open the hatch, turn switch S3 inside the control unit to position 1.
If the hatch does not open, the reason may be that the safety switch
is in position 0 or the linear motor is incorrectly connected. To close
the hatch, return the switch to position 0.
4. Checking the operation of pressurisation
Close all stairwell doors.
Start pressurisation by turning the PRESSURISATION switch on the
control panel to position MAN. Alternatively, with the PRESSURISA-
TION switch in position AUT, pressurisation can be activated from an
external system or by triggering a smoke detector using test gas.
The red PRESSURISATION light on the control panel should come on.
The fan unit hatch opens.
In approximately 20 seconds, the fan will start running and air will
start flowing into the stairwell. If the flow of air is in the wrong direc-
tion, interchange the connection of two phase conductors to the fan
motor.
The frequency converter in the control unit adjusts the fan speed ac-
cording to the differential pressure value measured by the pressure
transmitter and tries to maintain an overpressure of, for instance, 50
(±5) Pa in the stairwell.
If the pressure will not rise, check the transmitter hoses and make
sure all doors are properly closed.
If the pressure oscillates too much, adjust the pressure controller ac-
cording to the instructions.
The intended air release path has to be kept open during testing to
reduce vibrating.
With the PRESSURISATION switch in position AUT, reset the relay unit
in the control unit by pressing the RESET button. The fan stops and
the hatch closes.
SEMI-ANNUAL INSPECTIONS
• Use the control panel switches to check the operation of the unit by
letting it run approx. 10 minutes (see Initial inspection).
ANNUAL INSPECTIONS
• Carry out the measures described under Initial inspection.
• Check that the hatch of the fan unit opens without trouble. Re-
move any obstructions. On the hatch opening motors, the following
should be checked.
1. Security of motor mountings
2. Protection against moisture
3. Operation (testing) and electrical connections of the motors
• Also check that the hinges of the hatch are properly secured, and
that the seals are tight.
• Check the condition of the transmitter hoses. Replace hoses as
necessary.
• For resetting the pressure transmitter the hoses need to be de-
tached from the transmitter. See installation of pressure transmit-
ter.

CONNECTIONS TO AN EXTERNAL SYSTEM, E.G. AN
APARTMENT SMOKE EXTRACTION WINDOW OR A FIRE
INDICATOR SYSTEM
Pressurisation can be switched on from an external system using po-
tential free, normally open contacts. The contacts shall remain closed
during pressurisation. The voltage in the circuit is 24 VAC.
The control unit provides potential free ”run” and ”alarm” signals. The
“run” signal is activated when pressurisation or smoke extraction is in
operation. This signal can be used for activating the emergency stop
function of building ventilation, for instance.
A warning signal is given if the system has a fault that prevents its op-
eration.
MAINTENANCE AND CONNECTIONS TO AN EXTERNAL SYSTEM
MAINTENANCE OF ELECTRIC COMPONENTS
Maintenance of the automatic system:
• Reset the pressure transmitter once a year.
• Clean smoke detectors when an error message has occurred.
• Replace fuses in the control unit as necessary.
• Annually inspect the frequency controller fan, and replace as
necessary.
• Check control panel glass once a year.
• Check and replace control panel LEDs as necessary
OPERATIONS FOR FAN MAINTENANCE
The fan bearings must be replaced every ten years.
Before starting maintenance work, at the power supply cabinet switch
off the power supply to the fan and make sure that it cannot be acciden-
tally switched on. Also turn the safety switches to position 0.
First, expose the impeller end of the fan (safety switches), remove the
safety mesh (if applicable) and the impeller.
Then, undo the screws visible at the end of the electric motor, and with-
draw the motor end cover together with the rotor.
Replace the bearings on the rotor shaft and assemble the parts in re-
versed disassembly order.
