1. Product Description
Fire Dampers are generally used for control in air distribution system. In the event of fire, Fire Damper will shut automatically, discontinuing airflow into the room, thus, prevent spreading of fire.
This range of Marine Fire Dampers are designed according to special requirements of the Marine Industry, for use in the emergency generator system, air distribution and fire control, engine room ventilation and other related applications. The most significant characteristics of our Marine Type Fire Damper is that it comes with an electrical actuator, which enables rapid closing of the damper blade when an electric signal is sent. Once the damper blade is shut, the control system will send a message to inform the control tower. The Marine Fire Damper can be operated in three ways, the manual operation mode, the electrical operation mode and activation by thermal fuse unit.

Our Marine Type Fire Damper has attained DNV Quality System Certificate of Assessment.

OPERATION METHOD
The damper is fitted with an electrical actuator which enables rapid closing of the damper blades. It can be operated in three ways.
[1] MANUAL OPERATION MODE
[ Closing ]
Pull the MANUAL LEVER. This actuates thespring to release(ADS-B101) causing the damper blades to close momentarily.
 Closed
[ Reset ]
Turn the MANUAL HANDLE counterclockwise until the indicator reaches position "O" on the scale, locking the damper blades.
 Reset
[2] ELECTRICAL OPERATION MODE
The electrical actuator closes the damper blades rapidly once signal (D/DC 24V) is received from control centre. Once the damper is closed, confirmation signal and reporting signal will be sent out immediately at any time.
[3] ACTIVATION BY THERMAL FUSE UNIT
A temperature above 72 °C in the damper duct causes the temperature fuse to be melt. The shaft of the fusible link, in turn, unlock the fuse arm to activate the spring in the ADS-B101, thus causing the damper blades to close momentarily.
