1. INTRODUCTION
The purpose of this Operation and Maintenance Manual is to familiarize the user with
the intended use, design, operating principle, installation, periodic maintenance and
operation of the product. Observing instructions contained in the Operation and
Maintenance Manual will ensure correct operation of the device throughout its entire
lifetime.
SCD smoke dampers together with the control system may constitute the
configuration of several components made by various Manufacturers. Each component is
delivered along with the Manufacturer’s Manual. Both – assembly companies and the User
–are obliged to read those Manuals and apply them with regard to installation, operation
and maintenance.
2. FORMAL AND LEGAL ASPECTS OF INTRODUCING SCD SMOKE DAMPERS
INTO THE MARKET
Certificate of Constancy of Performance No. 1438-CPR-0503, specified in PN-
EN 12101-2:2005, is a legal basis for using SCD smoke dampers.
3. INTENDED USE AND PRODUCT CLASSIFICATION
SCD smoke dampers are used in public buildings, warehouses, production facilities
etc. They are designed for mounting onto flat roofs slanted at not more than 15°.
The main function of SCD smoke dampers is extracting smoke and hot toxic gases
occurring during fire in the under-ceiling space.
SCD smoke dampers by Smay Sp. z o. o. have openable leafs filled with translucent
material. Therefore, they additionally function as spot skylights. The third function of SCDs,
when appropriate tooling is used, is cyclic ventilation.
In each and every case smoke extraction is the priority function of SCD smoke
dampers. SCDs make it possible to evacuate people and enable rescue services to
undertake appropriate intervention by keeping the lower areas of a building, including
escape routes, free of smoke. Smoke dampers reduce the thermal load of the building
structure by reconducting the heat created during a fire, and thus reducing material injury
caused by the fire.
Using SCD smoke dampers gives the possibility to lower the building fire protection
class, enlarge permissible fire zones and lengthen escape routes.
SCD smoke dampers are classified according to PN-EN 12101-2 criteria, with regard
to the following areas:
Reliability: double action, Re 1000,
Snow load: SL550 –SL 1000 (depending on the drive size and type),
Low temperature: T(00) –T(–25) (depending on the drive size and
type),
Wind load: WL 1500,
Resistance to high temperature: B 300,
Single leaf damper effective areas are presented in Table 1, and double leaf damper
effective areas –in Table 2.
It is possible to make the dampers in the version meeting the requirements of
the BROOF(t1) classification. The properties distinctive for the skylight function are
declared according to EN 1873:2014+A1:2016 requirements

4. TECHNICAL DESCRIPTION OF PRODUCTS
4.1. DESCRIPTION/TYPES
SCD smoke dampers are rectangular in cross-section. They are available as single or
double leaf. The dimension range is specified in Tables 4 and 5.
The opening angle of a single leaf damper is not less than 140°.
The opening angle of a double leaf damper is not less than 90°.
A profiled aluminium drainpipe is mounted on a straight or sloping base, made of
1.5 mm thick galvanised sheet metal. The purpose of the drainpipe is to drain the
condensation moisture created as the result of temperature difference on the inner surface
of the leaf. The drainpipe corners are sealed with silicone and secured with an aluminium
fitting.
The base is adapted for placing insulation material on its entire perimeter. It is
recommended to use mineral wool insulation, 50 mm thick. The insulation material should
be of A1 reaction-to-fire class and be characterised by high density (150 kg/m3 minimum)
and thermal insulation power (thermal resistance Ri = 1.25 m2∙K/W minimum).
Heat-transfer coefficient for the base insulated by means of 50 mm thick mineral wool
is U = 0.80 [W/m2K].
Moisture tightness is obtained by means of applying insulation with bituminous
materials or sheet-metal work, appropriate for the given roof structure.
The drainpipe is connected, alongside the longer side of the damper, by means of a
linear rack hinge, with an openable cover. The hinge is protected against unwanted

impurities by means of an aluminium cover. The cover frame is a one-piece item made of
specially designed aluminium profile, which makes it possible to mount porous
polycarbonate cover, 10, 16, 20 or 25 mm thick.
In the basic version Lexan LT2UV169X Opal White polycarbonate plate, 16 mm thick,
is used. Important properties of this material are presented in Table 3.

Explanations for the parameters presented in Table 1 are given in the original Manufacturer’s notation.
Light Transmission D65 (% LT) - Percentage of the incident visible light that passes through an object.
Direct Solar Transmission (%DST) - Percentage of incident solar radiation that passes directly through an
object.
Total Solar Transmission (%TST) - The percentage of incident Solar radiation transmitted by an object which
includes the direct Solar Transmission plus the part of the Solar Absorption reradiated inward.
Solar Heat Gain Coefficient (SHGC) - or g-value is the total solar energy that enters the interior of a building,
divided by 100.
Shading Coefficient (SC) –The ratio of the total solar radiation transmitted by a given material to that
transmitted by normal 3 mm glass, whose light transmission is 87%. SC=%TST/87.
Light to Solar Gain Ratio (LSGR) - The ratio between total light transmission (LT) and the total solar
transmission (TST).
The contact between the polycarbonate plate and the cover profile is sealed by
means of a EPDM profile gasket. The polycarbonate panel is pressured to the gasket by
means of an aluminium lock profile of the height appropriate to the panel thickness.
The airtightness is obtained by means of using a EPDM gasket mounted between the
cover and drainpipe profiles.
The aluminium profile shapes and dimensions are patented.
The whole damper is made with the use of mounting technologies, which may be
used both in a production plant and at a stand prepared at a building site, or directly on the
building roof. The dampers may be delivered as an easy-to-transport set of ideally matched
parts, with all the connecting members needed. The mounting procedure takes place on
the basis of a clearly presented manual, by means of standard fitting tools, without the
need to use a welder or a grinding machine.

It is possible to deliver completely assembled dampers. In this case, in each damper
with a pneumatic drive, in order to make it ready for operation, a thermal trip –delivered
separately –needs to be mounted and set. Deflectors are delivered separately as well.
Moreover, the delivery of assembled dampers requires individual agreements on
installation and insulation preparation.
Smoke Dampers with the SCD-1-W Roof Hatch Function
Smoke dampers with the roof hatch function, besides all functions of standard
dampers, also enable workers to get on the roof. They are made with a straight base only,
in two versions:
Version 1 –with a single electric actuator –for dimensions 1000 x 1000 and
1000 x 1200,
Version 2 –with two electric actuators –within the range from 1000 x 1300 to
1800 x 1800. Their detailed description is presented on page 22.

St –straight base Pn –pneumatic actuator (exemplary selection. The actuator type depends on T, SL class)
Sl –sloping base El –electric actuator
Damper weight* –applies to dampers with 16 mm thick polycarbonate filling and SL 550
In exceptional situations there is the possibility of making dampers with different hole
dimensions, but only within the range of terminal dimensions shown in Tables 4 and 5.
The basic heights of the damper bases are 350, 500 or 700 mm.
It is possible to make dampers with other base dimensions, however not smaller than
350 mm. For dampers with base heights other than the basic ones, the dampers with a
lower base should be considered as valid declarations for Aa active area.

4.6. DRIVE SELECTION
In SCD smoke dampers, a basic function of emergency opening in order to extract
smoke is carried out by a pneumatic or electric 24 V actuator.
The function of damper release in order to vent for dampers with a pneumatic drive is
carried out by the 230 V or 24 V electric actuator (for dampers with maximum leaf
dimensions up to 1920 x 2500), double action pneumatic actuator or a second electric
actuator.
The power transmission from the actuator to the damper’s cover is carried out by a
special mechanism, and the cover position is set by a spring lock.
The selection of actuators for individual single leaf damper sizes is presented in
Table 8, and for double leaf damper sizes in Table 9. For intermediate dimensions or other
classification than the one given in Tables 8 and 9, it is possible to approximate actuators
meeting the durability and mechanical criteria.
