A fire rated roller shutter is only as reliable as the wall and wiring around it. Before you order, confirm where the door will sit and how the control side will be wired. The points below reflect how RHIDOOR sets up these doors on site.
Where the Shutter Should Sit
Open passages and halls that link atria between buildings should use fire doors or a fire rated roller shutter rated for at least 3 hours.
When two towers or adjacent low- and mid-rise buildings meet at a fire shutter, the wall assembly needs a rating of at least 2 hours. If the facing wall on the higher building is rated 2 hours or more and already carries fire doors, windows, or shutters, you can close the gap a little—but keep it over 4 meters.
The door in front of the fire elevator should be a fire door or a fire rated roller shutter with a hold-open function.
In towers with corridors, open stairs, escalators, or other floor openings, treat the joined floors as one fire zone and keep the combined floor area within the limit for that zone. If the upper and lower openings close with fire shutters or water curtains rated over 3 hours, you do not have to add the areas together.
On escape routes, fire louvers need open-close devices on both sides and must support automatic, manual, and mechanical control.
Fire Rated Roller Shutter Wiring
Two wiring setups are common. If the shutter only needs to close fully on alarm, read the active and passive outputs of the control module and land them on the full-descent terminals.
For a half-close then full-close sequence, the 8303 input-output module needs two control modules at the panel—confirm with your panel supplier—and you must read the active and passive outputs.
In a linked-control build, a control module connects the full-descent terminal to the DIP switch inside the control cabinet, and you set the half-close and full-close points with the dial codes. The fire shutter control box wiring follows the same module logic: match the active and passive outputs to the descent terminals, and keep the low-voltage run away from the motor power cable.
