Smoke Master SMPA - Installation, operation and maintenance

• The control unit, the control panel, and the fan unit use a

dangerously high voltage of 230V. The system should be

made dead before any electrical or maintenance work.

• Electric installations should only be carried

out by a suitably qualiﬁed electrician.

• Before any maintenance work is carried out on the fan

unit, the safety switches for the fan and for the hatch

opening motors should be turned to position 0.

• If the fan unit is installed in a place where it may cause

danger, access to the unit should be prevented.

• The installer and the operator are jointly

responsible for ensuring that the installation

complies with all local rules and regulations.

• If the pressure side is not ducted, the product shall

be provided with a safety mesh, e.g. BDKU.

SAFETY ASPECTS

Smoke Master SMPA - Installation, operation and maintenance

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.

ELECTRIC CONNECTIONS

Smoke Master SMPA - Installation, operation and maintenance

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.

Smoke Master SMPA - Installation, operation and maintenance

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.

Smoke Master SMPA - Installation, operation and maintenance

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.
