Fig.1. Halton SCS, model M = Actuator with insulated box, for manual activation system.


The Halton Sec Compact Rectangular a motorised rectangular smoke control damper that allows smoke to be extracted from the single compartment space by dedicated smoke extraction system.

The smoke damper is made of fireproof materials with incombustible glass fiber blade gaskets. They are preventing the air to infiltrate the extraction ducts to collect smoke from closed dampers.

The Halton Sec Compact Rectangular smoke control damper shall be connected to the control and testing system delivered by Halton or to common building automation systems. The smoke control damper can be used in fully automatic (SCS/A) or manual activation (SCS/M) systems.

In case of fire sequence of operation is important, smoke extract fans should not be started before the smoke control dampers are opened.


Smoke control damper Halton Sec Compact Rectangular can be installed on the certified single compartment ducts. Damper can be also installed on the wall or floor surface. The blade direction may be either horisontal or vertical.

The correct operation of the smoke control damper must be ensured before and after installation.

After fixing the smoke control damper check the diagonal dimension.
The damper should be cleaned after installation.

Detailed installation instructions, as well as an installer’s installation certificate form, are supplied with each product.

See also the section Documents for detailed installation guidance.

Installation on the single compartment duct

All dampers are delivered with an installation flange, which is used to fasten the fire damper with screws to the surface of steel duct or to a connection.

The gap between the damper and the supporting structure is filled with fireproof seal rock wool or firestop mastic, after fixing of the damper.

When Halton Sec Compact Rectangular is used as manual activated (MA) smoke control damper, connect the connection cables for electrical actuator inside of heat insulated box. Use nonflammable cables

Use M10 threaded rod for supporting the smoke control damper. See drawings below.

No regular maintenance is required for the product.

Regular testing with the separate testing system is recommended twice a year.
Upon failure during testing of the smoke damper, a Halton representative shall be connected to ensure appropriate operation of the product


Multi-blade-type single zone smoke control damper Halton Sec Compact Rectangular for rectangular and circular ducts with electric actuator and position indicator.

Damper has to fulfill the requirements from harmonized product standard EN 12101-8 and tested according to demands in standard EN 1366-10 and be labeled with CE Mark.

Damper has to be classified as:

E600 120(hodw-i↔o) S 1500C10000 AAsingle

E600 120(hodw-i↔o) S 1500C10000 MAsingle

E600 120 (vew-i↔o) S 1500C10000 MAsingle

The casing and blades of the smoke control damper shall be made of galvanised or stainless steel and the blade gaskets made of incombustible material.

The smoke control damper shall be installed horisontal and vertical position, CE marked, single compartment duct with incombustible sealing mass to ensure tightness of the connection
