The FD-CON-2 fire damper switch is a control unit for Halton Marine fire dampers.
The FD-CON-2 fire damper switch is a control unit for Halton fire dampers. The control unit is installed near the damper in a place where personnel has easy and logical access to it. Two or more FD-CON-2 units can be connected in series. This allows the damper to be locally controlled from both sides of the bulkhead or deck as per SOLAS regulation.
The FD-CON-2 is mainly intended for electrically operated dampers, but it can also be used for pneumatic dampers. In this case the FD-CON-2 unit controls the solenoid valve that controls the supply air to the damper actuator.
