Introduction

Instructions for installation, operation and control refers to the smoke dampers (hereafter dampers) circular DKIR1 and rectangular DKIS1, the products of Systemair. It contains basic information and recommendations regarding the installation, use and inspections that need to be followed to ensure proper and smooth operation of the dampers.

Resistance class E600120 (ved i ↔ o) S500C10000 AA single is valid for all nominal dimensions of round dampers (see Fig. 8) and for nominal dimensions of rectangular dampers where W > 1200 mm (see Fig. 10).

Resistance class E600120 (ved i ↔ o) S1500C10000 AA single is valid only for rectangular dampers with nominal dimensions H × W from 200 × 200 up to 1200 × 800 mm (see Fig. 9).

NOTE: These smoke dampers have flanges width 20 mm.
Introduction

Warnings
Some damper parts can have sharp edges – therefore it is necessary to use gloves during damper installation and manipulation.
In order to prevent an electric injury, fire or any other damage which could result from incorrect damper usage and operation, it is important to:

Install the damper in accordance with the installation manual and by a properly trained employee.
Execute the damper inspection in accordance with this installation, operation and maintenance manual.
Before you can install the smoke damper, it‘s functionality must be checked according to chapter 3 Check of the functionality.
This procedure prevents installation of a damper that has been damaged during transportation or handling.

Do not install functionless fire dampers!

Operating conditions

Smoke dampers are part of the Smoke and Heat Exhaust Ventilation System (SHEVS). Functionality of the smoke damper is following. In case of fire damper:

opens and removes the heat and smoke through a special fan from the fire compartment affected by fire or
closes and prevents the spread of smoke and heat in the fire compartment unaffected by fire.

All smoke dampers have electric actuator as standard. They are designed to be installed in the SHEVS ducts in locations that are protected from weather.
Systemair smoke dampers are passive in terms of noise. There is increased noise only when closing or opening the damper in case of inspection or fire (and it takes less than 60 seconds).

Installation

The installation must be done as follows:

Duct connected to the damper must be supported or suspended so that the damper do not bear its weight.
The damper must not bear any part of the supporting construction. This could lead to damage and subsequent failure of the damper.
Actuator can be on either side of the supporting construction, but it must be placed so that it is easy to access for inspection and repairs.
Distance between dampers and building structures, distribution technology and ventilation equipment must be large enough for reliable performance of the installation, functional testing, inspection and repair.
The distance between the dampers must be at least 200 mm according to EN 1366-10.
The distance between dampers and the wall or ceiling must be at least 200 mm according to EN 1366-10.
The gap between the damper and the selfstanding grill (when installed) must be at least 200 mm according to EN 1366-10. Otherwise the damper must be tested together with the grill. The smoke dampers must be installed with horizontal blade axis.
Before the installation of the smoke damper, it‘s functionality must be tested according to the chapter 3 Check of the functionality.

DO NOT INSTALL NONFUNCTIONAL SMOKE DAMPERS!

Changes of smoke damper functionality, caused by transport or installation, aren´t reclaimable after the installation (deformations, damages, mechanical damage of the sealing material, foreign objects which can constrain the blade, wrong handling of the activating mechanism etc.)
Before connection of the smoke damper into the ductwork, smoke damper‘s functionality must be checked again (according to chapter 3 Check of the functionality).

IT IS NOT POSSIBLE TO CLAIM FAULTY FUNCTIONALITY CAUSED BY PRODUCTION, TRANSPORTATION OR INSTALLATION AFTER CONNECTING THE DUCTS TO THE SMOKE DAMPER!

During installation, it is necessary to protect the damper mechanism and its interior against dirt. The blade must be in the closed position. It is necessary to avoid deformation of the damper. Installation and setup of the dampers is always determined by SHEVS project plans that must comply with the applicable regulations.
The smoke dampers DKIR1 must be installed according to Fig. 1, the smoke dampers DKIS1 must be installed according to Fig. 2. After damper installing into the SHEVS duct it is necessary to connect electrical installation that must be done only by authorized persons – connection has to be done according to Fig. 3 – 7. The actuators have two microswitches indicating the open and closed positions of the blade – see Fig. 3 – 6.
Setup, install, repair, overhaul and inspections of the dampers must be done only by the manufacturer or by the personnel trained by the manufacturer.

Before putting dampers into service after installation (and in subsequent periodic inspections) visual inspection and functional test must be conducted. After the visual inspection and functional test a record must be made into operational diary.

Operating and Maintenance

The damper operation

After installation, the damper must be set up into the operating position – closed. By connecting a power source to activate the actuator the blade shall move. Respective switching power supply achieves entry into the operating position – closed.

Maintenance

Systemair smoke dampers are maintenance free.

Check of the functionality

Switching the supply phase according to Figure 3 – 7 damper switch to the „open“:

The blade must come to the fully open position and must remain there detented.
After reaching the end position of the blade the appropriate signaling circuit must switch on

Switching the supply phase according to Figure 3 – 7 switch damper to the „closed“:

The blade must come up to the fully closed position and remain there detented.
After reaching the end position of the blade the appropriate signaling circuit must switch on.

Now the damper is in standby mode, so it must rest for normal operation.

Inspection of the damper

Each damper should be inspected after installation and every 12 months using following steps:

Identification of damper
Date of inspection
Check of the electrical connection of the activation mechanism
Check of the the electrical connection of the end switches
Check of the damper for cleanliness and eventually treatment (where necessary)
Removing of the cover of the inspection lid.
Check of the inspection lid, cover tightness and eventually correction and record (where applicable)
Check of the blade and sealings, and eventually correction and record (where applicable)
Check of the safety damper closure – details see Chap. 3
Check of the damper functionality (details see Chap. 3) opening and closing by the control system, tracking the physical behavior of the dampers and signalization of the end positions, and eventually correction and record (where applicable)
Closing of the cover of the inspection lid.
Set up into the operating position – see Chap. 2.1
Record into operational diary (page 6) with name and signature of the checker.

The damper is part of the SHEVS. Therefore the system must be checked as specified in its operational and maintenance requirements.
