Single-blade cut-off fire dampers (BFL 230-T, 200 × 200 mm) mcr FID C

Fire resistance: EI 120 (ve ho i<–>o)S/ E 120 (ve ho i<–>o)S

Versions:

• S – cut-off fire damper

Purpose: The damper has been designed for use in general ventilation systems (intake and exhaust types), at passages through space dividing elements – walls and floors.

Control – release:

KW1 mechanism – activated by a return spring with fusible link rated at e.g. 72°C or remotely by an electromagnet (pulse or power break), reset by means of a lever or additional actuator (Vn= 24V DC or 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 or remotely, by supply power decay (power break), remote reset by supplying power (Vn= 24V AC/DC or 230V AC).

Dimensions (to the accuracy of 1 mm): width 200 – 800 mm; height 200 – 400 mm; casing length 296 mm.
