Application
Intended for the compartmentalisation of public buildings (public buildings) and high-rise buildings (high-rise buildings).
Autocontrolled or remotely controlled Actuated Safety Devices (DAS), intended to restore the fire resistance characteristics of walls or floors crossed by a duct in the event of a fire and to isolate the disaster area.
Use inside buildings.
Can be mounted in any position (blade axis installed 0 to 360 °).
Range of valves validated for installation at a distance less than the minimum imposed by the European test standard, on vertical and horizontal walls.
For circular valves, the minimum distance is set at 30 mm.

CFTH: simple self-controlled mechanism
- Automatic closing of the valve as soon as the temperature in the duct exceeds 72°C (72° thermal fuse).
- Manual valve reset
- Integrated single-pole (CFTH FDCU) or double-pole (CFTH FDCB) start and end of travel contact.
BOBI: self-controlled + remote-controlled + scalable mechanism
- Automatic closing of the valve as soon as the temperature in the duct exceeds 72°C (72° thermal fuse).
- Closing using a current-release coil (BOBI VM 24/48 FDCB) or current-break coil (BOBI VD 24/48 FDCB) at 24 or 48V.
- Equipped as standard with bipolar end and start of travel contacts.
- Manual resetting of the valve.
- Remote reset possible on site with the addition of the ME BOBI Kit.
BOBI ME: self-controlled + remote-controlled + motorized mechanism
- Same as remote controlled Bobi.

UNIQ META: self-controlled + remote-controlled + motorized mechanism
- Automatic closing of the valve as soon as the temperature in the duct exceeds 72°C (72° thermal fuse).
- Closing using a current-release coil (VD) or current-break coil (VM) at 24 or 48V voltage.
- Supplied as standard in VM. Switch to VD by removing a switch.
- Equipped as standard with bipolar end and start of travel contacts.
