Any works related with installation, operation, maintenance and servicing of the vents
and skylights may only be performed in compliance with SHE requirements, and with use
of appropriate personal protective equipment - including fall arresting devices. Any
works necessitating working at height in order to make electrical connections, etc. may
only be performed by duly licensed persons.
2. PURPOSE OF DEVICE
mcr-PROLIGHT smoke vents are automatic smoke venting devices. The principal function of
mcr-PROLIGHT smoke vents is the removal of heat energy, fire gases, and smoke from
enclosed spaces (production floors, storage rooms, public amenity buildings, etc.) outside the
building, contributing to the protection of life and property, through:
• maintaining escape routes in a state of moderate smoke intensity,
• facilitating fire fighting and rescue operations by providing a bottom corridor with
moderate smoking intensity,
• ensuring protection for the building structure and its equipment,
• limiting fire damage caused by smoke, hot burning fumes and thermal decomposition
byproducts
The smoke vents may also serve the purpose of ventilation vents, smoke & ventilation vents, or
roof skylights.
The use of smoke vents provides the following opportunities to the Investor:
• lowering the building's fire resistance grade
• extending permissible fire zones,
• elongating evacuation routes
mcr-PROLIGHT smoke vents are part of a smoke control system that comprises other
MERCOR SA products, including, among others: mcr-PROLIGHT smoke vents in continuous
skylights and single skylights, mcr-PROSMOKE smoke curtains, mcr 9705 and mcr 0204 control
units, and others.
mcr-PROLIGHT smoke vents have a Certificate of Conformity WE 1488-CPD-0151/W,
issued by the Institute for Building Technologies in Warsaw, certifying the conformance
of the vents design with the requirements of PN-EN12101-2:2005, and Certificate of
Conformity 1396-CPD-0040 issued by Fires s.r.o., NB 1396, Slovakia, certifying the
conformance of the vents design with the requirements of EN 12101-2:2003.
3. DEVICE DESIGN AND PRINCIPLE OF OPERATION

5. DEVICE INSTALLATION
The device must be installed in observance of all the applicable SHE principles, particularly
those related with working at height, using adequate personal protective equipment.
The vents must rest on the roof's structural elements such as: purlin, trimmers, structural sheet,
reinforced concrete plinth. Any elements causing collision with the vent leaf at full opening
range should be removed.
The vents may be installed on roofs of steel, concrete or wooden structure. The vent base has a
protrusion (shelf) in its lower part, allowing to rest and fix the vent to the supporting structure.
Fixture elements should be selected depending on the supporting structure's making, according
to the below table. Fixtures should be installed at 50÷60 cm spacing.

The vent bases are ready for flashing works with roofing paper, PVC membrane or steel sheet.
The vent base, in its upper part, features a galvanized steel sheet strip at its full circumference,
which is used for fixing flashings/coverings using screws. For roofs covered with roof
membrane, an optional PVC-coated sheet strip may be used to facilitate installation.
NOTE
1. If roofing paper is to be welded to the above mentioned sheet strip, IT IS
ABSOLUTELY REQUIRED to use a cover for protecting the vent glazing and
spacer sleeves from the effect of fire/hot air.

2. After installing the vent, protective foil must be removed from all external
aluminium elements of the vent (pressing frames, pressing strip) and from the
vent glazing (PCA, laminate panels, acrylic domes). Leaving foil on the device may
cause permanent discolorations of elements, and become hard to remove.
3. If the vent is not supplied to the construction site preassembled, maintain special
caution when installing polycarbonate panels. Damaging the tape protecting the
edges of polycarbonate panels will cause contamination to penetrate into the PCA
chambers, which is not covered by warranty.

6. DEFLECTORS AND INLET DEFLECTORS
6.1. Wind deflectors
Deflectors are used to increase the active smoke exhausting area of smoke vents. In
standard, they are made of aluminium sheet.
Deflectors are delivered on site in the form of pre-bent elements. The vents are delivered
with deflector holders fixed to the vent base.
The deflectors may additionally feature bracing ribs. The ribs are fixed to the deflectors at
production stage.
Ø4.8x8 mm aluminum/steel rivets must be used for installing the deflectors, 2 pcs per each

6.2. Inlet deflector
Inlet deflector, in combination with the other deflectors, is used for improving the active
aerodynamic efficiency of DVP vents, i.e. the smoke exhausting area. The inlet deflector is
installed at the bottom of the vent base. It is made of galvanized steel sheet, optionally:
aluminium sheet; it may be painted to any RAL colour. The inlet deflector is pre-fixed to the
vent in transporting position. After installing the vent, the deflector should be fixed in working
position:
loosen the screws in fixture holders on side A of the deflector (in place of the
prepared bean holes)
undo the screws in fixture holders on side B of the deflector (in place of the
prepared Ø6.5 mm holes)
lower the deflector to operating position - according to the prepared holes
tighten the fixing screws (use only nuts with protection)

7. VENT LEAF ADJUSTMENT
(HOOK CONSOLE, EYE BOLTS AND ‘T’ BOLTS)
The vent leaf is joined with the actuator through a hook console, or - for small vents - directly.
The hook console is locked on a T bolt. Spindle-type pneumatic and electric actuators are
joined with the hook console using an eye bolt, which is screwed into the actuator's
spindle/rod. The vent leaf play should be eliminated by tightening the eye bolt or adjusting T
bolt. The eye bolt or T bolt should be secured from loosening with a counter nut. When using
auxiliary 230V~ electrical actuator for ventilation in systems with pneumatic actuator, the "T"
bolt is tightened into a toothed strip or spindle of the 230 V~ electrical actuator.

8. CONTROL
The functioning of smoke exhaust and smoke & ventilation vents is based on devices used
for controlling their opening and shutting. A set of such devices forms together a system for
smoke exhaust control or smoke exhaust and ventilation control. Depending on the
equipment used in it, the smoke exhausting control system may be offered in the following
variants:
• pneumatic system,
• electrical system,
• mechanical system.
Depending on the control method, mcr-PROLIGHT type DVP and DVPS flaps feature
pneumatic actuators with thermal triggers, electrical actuators or gas springs, and -
additionally - pneumatic and electrical actuators for controlling natural ventilation.
In the event of failure of the control that prevents the vent shutting, contact the service
department immediately (see point 11).
If the flap must be shut immediately, proceed with the following before the service
technicians arrive: disconnect the immobilized actuator from the leaf (e.g. disconnect the eye
bolt from the hook console, or undo the eye bolt from the actuator, or disconnect the actuator
from the cross-bar/console), then shut the leaf and secure it from opening.
8.1. Pneumatic control
Depending on the system's configuration, it may be necessary to connect additional
pneumatic piping to the vent (e.g. copper/steel tube from the alarm box containing
cartridges).
Threaded joints of pipe unions with valves, actuators, etc. must be sealed using appropriate
chemical agents, e.g. Loctite 243 (recommended) or Teflon tape, by winding it around the
thread. Apply several (2-3) drops of Loctite 243 per sealed thread. After screwing the
threaded joint together, Loctite 243 cures and seals the joint, securing it from uncontrolled
loosening (which is important for actuator connections). The loosening of a pipe joint secured
in such way is possible only using hand tools.

Fig. 27 Pneumatic actuator
For smoke exhausting purpose, the pneumatic actuators have an internal lock that prevents
the closing of a fully open vent leaf.
Method of closing the vent leaf after emergency opening for systems without remote shutting
function:
1. Release CO2from the system by screwing the cartridge out of the thermal trigger or
alarm box (note: the system contains high pressure - undo slowly, note: the
cartridge may cause frostbite).
2. Release the actuator locks (5) by raising them towards the working movement of the
actuator (as shown on the arrow on fig. 23).
3. Lower the vent leaf.
4. Check the leaf closure state.
5. Repeat actions 2-4 for the other leaf.
6. Insert a new CO2cartridge in the thermal trigger or alarm box.
7. Replace the thermal fuse (alcohol vial (2)) if required.
8.2. Electric smoke exhausting control
Leaf opening control system employing 24V= electrical actuator for smoke exhausting is
delivered preassembled in the vent. Preparing it for operation consists in connecting the eye
bolt of the electrical actuator with the pin of the hook console, and adjusting it properly so
that the console securely latches on the T bolt, and the electric actuator is disabled after the
vent shutting by the limit switch, and not the overload switch.
Method of connection of mcr-W / mcr-WSG actuator (cables polarity):
brown cable + brown cable –
blue cable –blue cable +
Mcr9705, mcr0204 smoke exhausting and ventilation control units and mcrR0424 and/or

8.3. Ventilation function
Ventilation function may be achieved using 2 basic methods:
by employing pneumatic actuators with appropriate installation,
by using an additional electrical actuator powered by 230V~ voltage (drawing below).
For transport reasons, the electrical actuator for ventilation function is usually not factory
installed. It is to be fixed in the upper cross-bar to the existing holes, using ST12-1/8 screws
(For Exxx-230 actuator) or threaded bolts (JMB actuators) supplied with the actuator. It is
recommended to secure the ST12 screws from loosening using Loctite 243, or similar agent.
The actuator has a T-shaped bolt that should be installed in place of the eye bolt. The hook
console should be latched onto the T bolt.
It is recommended to integrate into the system a weather automatics system for controlling
ventilation, e.g. mcrP054; its purpose is to shut any open vents in case of strong wind or
rainfall, protect user property and vent structure from damage.
