Sulku palopellit mcr FID S (BFL 230-T, 125 mm)
Single-plane cut-off fire damper and damper for fire ventilation systems.Tekninen informaatio
Fire resistance: EIS 90, EIS 90 AA, EIS 120, EIS 120 AA – depending on method of manufacturing, as well as method ja place of installation.
- S – cut-off Palopelti
- V – for fire ventilation systems (smoke exhaust)
- M – double-function for combined systems
- palopeltiä of the mcr FID S/S p/P, mcr FID S/S p/O Tyyppis with a thermal release unit are designed to be used in general ventilation systems, where these systems run through osaitions. In the event of fire, these palopeltiä enable the osaition, through which ventilation ja air-conditioning ducts run, to retain its fire resistance properties. In normal operating conditions damper’s screen is open. If a fire breaks out, the damper is closed.
- palopeltiä of the mcr FID S/V p/P Tyyppis can be manufactured without a thermal release unit. They are used in fire ventilation systems. In normal operating conditions, the damper’s screen is closed. In the event of fire the screen opens, therefore smoke ja fire gases can be exhausted through the device.
Tyyppis of palopeltiä:
- mcr FID S/S p/P; mcr FID S/V p/P – rectangular palopeltiä with an insulating separator,
- mcr FID S/S p/O – round palopeltiä with an insulating separator.
Control – release:
KW1 mechanism – activated by a return spring with fusible link rated at e.g. 72°C tai remotely by an electromagnet (pulse tai power break), reset by means of a lever tai additional actuator (Vn= 24V DC tai 230V AC). RST mechanism – activated by a return spring with fusible link rated at e.g. 72°C, manual reset by means of a lever.
Electrical actuator – activated by a thermocouple rated at e.g. 72°C tai remotely, by supply power decay (power break), remote reset by supplying power (Vn= 24V AC/DC tai 230V AC).
Electrical actuator – activated remotely, by supplying power (pulse), remote reset by resupply of power (Vn= 24V AC/DC tai 230V AC).
