Seattle Department of Construction and Inspections (DCI) has high-rise requirements for a roof hatch when approved as a penthouse alternate.
Seattle DCI has the following 8 requirements:
1. Roof hatch dimensions shall be a minimum of 3'-0" wide x 12'-0" long.
2. Roof hatch shall be installed with a snow sensors/heating cables system.
3. Roof hatch shall be motorized with a remote pushbutton station located at the base of the top stair landing leading to the hatch.
4. Roof hatch electrical system shall be on building emergency power.
5. Provide switch in the Fire Command Center that unlocks the electro-magnetic locks on the hatch doors.
6. Interlock electromagnetic locks on hatch doors with fire alarm system to unlock
automatically on any fire alarm signal.
7. Ensure code compliant stairs and height for stairs is met where the stair leads to
the hatch.
8. Roof hatch shall be operable from the roof.
Has anyone out there sourced a manufacturer that can furnish such a hatch?
Thanks,
Wayne |
