[Fire-rated roller shutter] Site requirements and wiring
RHidoor’s site requirements for installing fire-rated roller shutters:
(1) Passages and halls linking atria between buildings should have grade B fire doors or fire shutters, with a fire rating over 3.00h.
(2) Where two high-rises or adjacent single/multi-story civil buildings install fire shutters, the rating is at least class 2. When the adjacent higher exterior wall has a rating of at least 2.00h and has fire doors, windows, or shutters, the fire gap may shrink a bit but should stay over 4.00m.
(3) The fire elevator front door should use a grade B fire door or a fire shutter with a hold-open function.
(4) High-rises with corridors, open stairs, escalators, or other floor openings should treat the linked floors as a fire zone; the total allowed floor area must not exceed the 5.1.1 rule. When the upper and lower openings have fire shutters or water curtains with a rating over 3.00h, the areas need not add up.
(5) Fire louvers on escape routes should have open-close devices on both sides and support auto, manual, and mechanical control.
Wiring method:
There are two wiring setups. First, if no full descent is needed, just know the active and passive outputs of the control module and connect them to the full-descent terminals.
Second, for half-descent plus full-descent, the 8303 input-output module needs two control modules at the host (ask the host seller), and you must know the active and passive outputs.
The linked-control build uses a control module to connect the full-descent terminal to the DIP switch in the control cabinet, with half-descent plus full-descent dial codes.
