Operating Models

Electric actuator

In the electric actuator (24 V and 230 V) system when a signal from building automation reaches the actuator or the fuse reacts to a rise in temperature (72 °C) power supply is switched off and the spring closes the damper blade. When the power supply is turned back on (e.g. during routine testing), the actuator opens the damper blade. The actuator is equipped with built-in limit switches for both open and closed position.

These actuators have a visual position indicator and fuses can be replaced from outside the device.

AC/DC 24 V (L1, F1, B1)

The Halton Exe Sturdy Circular fire damper with the 24 V electric actuator option must be connected to buildings fire damper management control system. We recommend our Modbus based network solution, Halton Safe HSM management system. This system enables the use of smoke detectors in ductwork or room spaces.

Operationally, when the Halton Safe HSM receives a signal from the fire alarm or smoke detector the power supply is turned off and the spring return actuator drives the damper blade to the closed position. When the power supply is reinstated (e.g. during routine testing) the actuator drives the damper blade to the open position.

The fire damper can also be connected to other commonly used building automation systems.

AC 230 V (L2, F2, B2)

The Halton Exe Sturdy Circular fire damper with the 230 V electric actuator option must be connected to buildings fire damper management control system.

Mechanical spring release (failsafe)

In Halton Exe Sturdy 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.

This operating model has a visual position indicator and fuses can be replaced from outside the device.

The limit switch (accessory) 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 (fail safe), 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. 

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

Function

The Halton Exe Sturdy Circular fire damper is CE certified for vertical (ve) and horizontal (ho) installation in concrete, masonry and lightweight structures. It fulfils the fire resistance class up EI 120 (ve ho i <-> o) S requirements.

General

Fire dampers are shutters in ventilation duct systems and prevent spreading of the fire and smoke from one fire department to the other. They are equipped with either an electric operating model (actuator) or mechanical spring release (failsafe). Under both options, a fuse reacts to a rise in temperature, causing a spring-return damper blade to close position.

A fire damper with electrical actuator must be connected to a common fire alarm or building automation system.

In the electric actuator (24 V or 230 V) system, when a signal from building automation reaches the actuator or the fuse reacts to a rise in temperature (72 °C), the power supply is switched off, the spring closes the damper blade and seals the duct fire and smoke tightly. When the power supply is turned back on (e.g. during routine testing), the actuator opens the damper blade. The actuator is equipped with built-in limit switches for both open and closed position.

Alternatively, the fire damper can be delivered with a mechanical spring release (fail safe) with a fuse that reacts to the rise of temperature (72 ºC) and the mechanical spring closes the damper. It needs to be opened manually.
 

Fire damper management system

It is recommended that the fire damper with an electrical actuator is connected to an automatic fire damper management system, e.g. Halton Safe. Testing for fire dampers can be done automatically in Halton Safe.

Only fire damper with 24 V electric actuator can be connected to the Halton Safe HSM control and testing system. This system enables the use of smoke detectors in ductwork or in the rooms.

Operationally, when the Halton Safe receives a signal from the fire alarm or smoke detector the power supply is turned off and the spring return actuator drives the damper blade to the closed position. When the power supply is reinstated (e.g. during routine testing) the actuator drives the damper blade to the open position.

The Halton Exe Sturdy Circular fire damper can also be connected to common building automation systems.

Servicing

No regular maintenance is required for the product.

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

A fire damper with electrical actuator must be connected to a common fire alarm or building automation system.

It is recommended that the fire damper with an electrical actuator is connected to an automatic fire damper management system, e.g. Halton Safe HSM with operating voltage AC 24 V. Testing for fire dampers can be done automatically in Halton Safe HSM.

The fuse of a fire damper equipped with an electric actuator must be replaced if the fuse has been released because of a rise of temperature in the duct. The fuse can be changed from outside the fire damper.

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

The fire damper is equipped with one inspection hatch, enabling the possibility to check the position of the damper blade. The actuators (electrical and mechanical spring release) include position indicators, open and close

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.
