Operating Model

Mechanical spring release (failsafe)

In Halton Exe Fold Circular fire damper with mechanical spring release, the fuse reacts to the rise of temperature (72 ºC) and the mechanical spring closes the damper blade. It needs to be opened manually.

The limit switch (accessory, see Fig.1.) indicates the damper blade position. When the damper blade is open (safe position), the limit switch indicates this position. If the damper blade is closed (failsafe), the limit switch sends an impulse to the monitoring system. This system triggers an alarm and/or stops/starts fans, depending on the designed system. The limit switch has no influence on the thermal fuse or release mechanism. 

Fuse can be replaced by removing the fire damper from the duct and placing it back after adjusting.

The maximum operating voltage and current is 230 V, 5A.

Function

The Halton Exe Fold Circular fire damper is CE certified for vertical (ve) installation in concrete, masonry or lightweight walls fulfilling the fire resistance class up to EI 120 (ve ho i <-> o) S requirements.  Also certified for horizontal (ho) installation in concrete or masonry ceilings/floors fulfilling the fire resistance class requirements EI 60 (ve ho i <-> o) S.

Fire dampers are shutters in ventilation duct systems and prevent spreading of the fire and smoke from one fire department to the other.

The fuse reacts to a rise in temperature, causing a spring-return damper blade to close position. Once the fire damper has closed, the blade and sealing close the duct tightly, effectively preventing the spreading of flue gases and fire.

The mechanical spring release fuse release temperature is 72 °C. It needs to be opened manually.

The fire damper with limit switch (as accessory) can also be connected to common building automation systems.

Installation

Please see/download Installation Guide for this fire damper from section Downloads.

Servicing

No regular maintenance is required for the product.

To ensure proper operation of fire dampers, an inspection must be carried out regularly according to local building codes. The minimum recommended inspection period is every 6 months. Documentation of testing must be saved for future needs.

If the fuse of a fire damper with a mechanical spring release (failsafe) is worn out it must be replaced.

Fuse can be replaced by removing the fire damper from the duct and placing it back after adjusting.

Upon failure during testing of the fire damper, maintenance service shall be ordered from an authorised Halton representative to ensure appropriate operation of the product.
