Packaging Properly dispose of packaging material. 12 Fire damper Type FKS-EU Parts and function FKS-EU with spring return actuator 4 Parts and function 4.2 FKS-EU with spring return actuator Fire dampers are used as safety related components in ventilation systems. The fire damper is used as a shutoff device to prevent fire and smoke from spreading through ducting. During normal operation the damper blade is open to enable air passage through the ventilation system. If the temperature increases in the event of a fire, the damper blade closes. Closure is triggered at 72 °C ( 95 °C in warm air ventilation systems). If the damper blade closes due to a temperature increase (i.e. in the event of a fire), it must not be reopened. To ensure proper functioning of the fire damper, a test can be carried out.

As long as power is supplied to the actuator, the damper blade remains open. In the event of a fire, the internal thermoelectric release mechanism closes the damper blade when at least one of the following is true: Temperature in the fire damper > 72 °C or > 95 °C Ambient temperature outside the release mechanism > 72 °C The power supply is interrupted (power off to close) As standard, the spring return actuator is equipped with limit switches that can be used to indicate the damper blade position. Functional description In fire dampers with a fusible link, damper closure is triggered by the fusible link. If the temperature inside the fire damper rises to 72 °C or 95 °C, the fusible link triggers a coil spring mechanism. The coil spring mechanism then causes the fire damper to close. As an option, the fire damper can be either supplied or subsequently fitted with one or two limit switches. The limit switches can signal the damper blade position to the central BMS or fire alarm system. One limit switch each is required for damper blade positions OPEN and CLOSED.

The thermal release mechanism closes the air transfer unit when the release temperature (72 °C) is reached. Smoke can, however, spread below this temperature. Air transfer units are installed in places where the general building inspectorate sees no risk, for example: Fig. 7: FKS-EU with spring return actuator and duct smoke detector ① ② ③ ④ ⑤ ⑥ ⑦ ⑧ ⑨ ⑩ Casing Inspection access Temperature sensor Damper blade with seal Travel stop Thermoelectric release mechanism Spring return actuator Cover grille Extension piece Duct smoke detector RM-O-3-D Functional description Functional description 4.4 FKS-EU with spring return actuator and duct smoke detector As an inlet for additional supply air in the walls of required corridors (escape routes) if the units are installed near the ground (up to 500 mm above OKFF) In installation shafts as long as they have sufficient fire resistance where they penetrate compartment floors In installation ducts as long as they have sufficient fire resistance where they penetrate compartment floors or walls (except for necessary corridors or escape routes) If the duct smoke detector detects smoke, the spring return actuator closes the damper blade. This prevents smoke from being transferred via ductwork into adjacent fire compartments even before it reaches a temperature that would trigger the thermoelectric release mechanism. As long as power is supplied to the actuator, the damper blade remains open. In the event of a fire, the fire damper shuts when at least one of the following is true: Smoke detected at the smoke detector Temperature in the fire damper > 72 °C Ambient temperature outside the release mechanism > 72 °C The power supply is interrupted (power off to close) The air transfer unit consists of the FKS-EU fire damper with general building inspectorate licence Z-19.18-2127, with a thermal release mechanism for 72 °C and with cover grilles on both sides, but without a duct smoke detector. 14 Fire damper Type FKS-EU Installation Installation situations 5 Installation 5.1 Installation situations Note The performance classes of the fire damper and the wall or ceiling slab may differ.

Fire damper Type FKS-EU Commissioning 9 Commissioning Before commissioning Before commissioning, each fire damper must be inspected to determine and assess its actual condition. The inspection measures to be taken are listed in the table on Ä on page 54. Operation During normal operation the damper blade is open to enable air passage through the ventilation system. If the temperature in the duct or the ambient temperature rises in the event of a fire (≥ 72°/≥ 95°), the thermal release mechanism is triggered and closes the damper blade. CLOSED fire dampers Fire dampers which close while the ventilation and air conditioning system is running must be inspected before they are opened again in order to ensure their correct function Ä ‘Inspection’ on page 52. Fire damper Type FKS-EU 51 Maintenance Lubricating points 10 10.1 Maintenance Maintenance The fire damper and the spring return actuator are maintenance-free with regard to wear but fire dampers must still be included in the regular cleaning of the ventilation system. General General safety notes DANGER! Danger of electric shock! Do not touch any live components! Electrical equipment carries a dangerous electrical voltage. – – Only skilled qualified electricians are allowed to work on the electrical system. Switch off the power supply before working on any electrical equipment. CAUTION! Danger due to inadvertently actuating the fire damper. Inadvertent actuation of the damper blade or other parts can lead to injuries. Make sure that the damper blade cannot be released inadvertently. Cleaning The fire damper may be cleaned with a dry or damp cloth. Sticky dirt or contamination may be removed with a commercial, non-aggressive cleaning agent. Do not use abrasive cleaners or tools (e.g. brushes). Inspection The fire damper must be inspected before commissioning. After commissioning, the function has to be tested in regular intervals. Local requirements and building regulations must be complied with. The inspection measures to be taken are listed under Ä on page 54. The test of each fire damper must be documented and evaluated. If the requirements are not fully met, suitable remedial action must be taken. Repair Regular care and maintenance ensure operational readiness, functional reliability, and long service life of the fire damper. The owner or operator of the system is responsible for the maintenance of the fire damper. The operator is responsible for creating a maintenance plan, for defining the maintenance objectives, and for the functional reliability of the fire damper. For safety reasons, repair work must only be carried out by expert qualified personnel or the manufacturer. Only original replacement parts are to be used. A functional test Ä 47 is required after any repair work. 10.2 Lubricating points Only lubricate the fire damper if the damper blade cannot be opened or closed easily. Use only oil or grease that is free of resins or acids. Functional test The functional reliability of the fire damper must be tested at least every six months; this has to be arranged by the owner or operator. If two consecutive tests, one 6 months after the other, are successful, the next test can be conducted one year later. The functional test must be carried out in compliance with the basic maintenance principles of the following standards: EN 13306 DIN 31051 EN 15423 Fig. 48: FKS-EU lubricating points The function of fire dampers with a spring return actuator can also be tested with an automatic control unit Ä ‘Functional test with automatic control unit’ on page 49. 52 ① Push rod bearings ② Damper blade bearings (both sides) Fire damper Type FKS-EU Maintenance Replacing the fusible link 10.3 Replacing the fusible link Replacing the fusible link Fig. 49: Removing the fusible link holder 1.
