Round Fire Damper CR60-L500
Optimised round fire damper 60-90′
The CR60-L500 round fire damper has a tunnel casing extension at the wall side. This casing extension of the round fire damper is used to facilitate the connection to the duct when the supporting construction is thicker than 100 mm. This round fire damper is available in diameters from 100 mm to 315 mm and ensures 60 or 90 minutes of fire resistance.
Available diameters 100mm > 315mm
Benefits:
- CR60-L500 round fire damper is easy to install
- Optimal free air passage and minimal pressure loss
- CR60-L500 round fire damper ensures an optimal acoustic performance
- Higher net building volume through compact size
- Air-tightness class C according to EN1751
- EIS60 classification

Spring return actuator ONE 24V (with fusible link) + bipolar beginning- and end-of-range switch - ONE T 230 FDCB
Spring return actuator ONE 230V (with fusible link) + bipolar beginning- and end-of-range switch
UNLOCKING
- manual unlocking
shortly press the unlocking button (1) once. - automatic unlocking
the fusible link reacts as soon as the temperature in the duct reaches 72°C. - remote unlocking
by interrupting the power supply.
RESETTING
- manual resetting
open the battery compartment (4) and press a 9V battery against the contact springs. Hold this position until the LED (3) emits a continuous light. Check whether the indicator (2) shows that the damper blade is in the open position. Remove the battery, the LED fades away. Close the battery compartment. - motorised resetting
switch off the power supply for at least 5 sec. Power the actuator (respect the prescribed voltage) for at least 75 sec. The resetting stops automatically when the end of range is reached (damper open).

UNLOCKING
- manual unlocking
shortly press the unlocking button (1) once. - automatic unlocking
the fusible link reacts as soon as the temperature in the duct reaches 72°C. - remote unlocking
via ZENiX controller
RESETTING
- manual resetting
Open the battery compartment (4) and press a 9V battery against the contact springs. Hold this position until the red LED (3) emits a continuous light. Control whether the indicator (2) indicates that the damper blade is open. Remove the battery. Close the battery compartment. - motorised resetting
via ZENiX controller. By applying voltage during first use.

 | The spring return actuator BFL(T) is especially designed to operate fire dampers remotely. The BFL(T) variant is intended for fire dampers with smaller dimensions (CR60, CR120, CR2 with ø ≤ 400 mm, CRS60 with ø ≤ 315 mm, CU2 / CU2-15 / CU4 with B+H ≤ 1200 mm or for CU-LT and CU-LT-1s). For Markage FD with H = 200 mm or H = 2200 mm (in combination with BFT motor).

OPTIONS – SWITCH
- SN2 BFL/BFN
Auxiliary limit switch ‘open/closed’
UNLOCKING
- manual unlocking
place the locking button on “unlock”. (In case of BFLT: the damper can alternatively be unlocked by pushing the “test” button on the thermo-electric fuse) - automatic unlocking
the thermo-electric fuse reacts as soon as the temperature reaches 72°C (type BFLT). - remote unlocking
by interrupting the power supply.
RESETTING
- manual resetting
turn the enclosed handle anti-clockwise. To block the motor, place the locking button on “lock” - motorised resetting
switch off the power supply for at least 10 seconds. Supply the actuator (respect the prescribed voltage) for at least 75 seconds. The resetting stops automatically when the end of range is reached (damper open) – it takes about 60 seconds to reset the damper – or when the power supply is interrupted.
