Application

Compartmentalization of ERP (Establishments Receiving the Public) and IGH (High-Rise Buildings).
Actuated Safety Devices (DAS) self-controlled or remote-controlled, intended to restore the fire resistance characteristics of the walls or floors crossed by a conduit in the event of fire and to isolate the disaster area.
Use inside buildings.

Control mechanisms:
- CFTH: self-controlled single-trip mechanism by 72°C fuse.
- UNIQ VD/VM FDCB: remote-controlled mechanism with 24 or 48V make or break with limit switch and bipolar start of run as standard.
- UNIQ VD/VM FDCB ME: triggering by emission or rupture 24 or 48V with end contact and bipolar start of run and reset motor.

Description

72°C thermal fuse supplied.
Manual trigger possible.
Manual reset possible (handle provided for CFTH mechanism).
Sealing class B as standard (C as an option).
Control mechanism entirely out of the wall.
Tunnel in refractory panels.
Graphite band all around the tunnel.
Intumescent seal.
30 mm frame for connection to ducts fitted with flanges (the 4 corners are fitted with elliptical holes Ø8.5 x 16 mm).
Mounting possible in all positions.

Simple self-controlled mechanism CFTH

The damper closes automatically as soon as the temperature in the duct exceeds 72°C.
The reset of the valve is done manually.

UNIQ remote control mechanism

The damper closes automatically as soon as the temperature in the duct exceeds 72°C.
The damper can also close by current emission (VD) or current failure (VM) in voltage 24 or 48V.
As standard, the mechanism will be delivered in current emission (VD), switching to a power outage on site will be done by switching a switch.
The UNIQ remote-controlled mechanism is equipped with FDCB bipolar end and start of run contacts (standard version).
The resetting of the valve is done using a 9V battery (not supplied) to be inserted in the compartment provided for this purpose.
Remote resetting is possible by adding the ME-UNIQ resetting motor kit.
The ME reset motor can be delivered factory-assembled or supplied as a kit for on-site assembly.
The UNIQ VD/VM FDCB kit allows the simple CFTH mechanism to be replaced on site by the UNIQ remote-controlled mechanism.
