Fire Shutter and Frame
Designed to prevent the spread of fire between separate compartments.
The fire shutter (MAY502A) is made of 16 gauge zintec steel and has a fire rating of one hour. It is designed to fit between the front cover of the fan and the main body. It must be used in conjunction with the fire protected building in frame (MAY907 A).
The fire shutter is gravity operated and is held open by a fusible link.
If heat increases above specified temperature, the link breaks and the shutter will close, sealing the duct.
NOTE: Full installation and wiring instruction are included with each fan. |
