After the post-epidemic return to work, the edge RHIDOOR’s fire rated electric roller shutter brings is better automatic control. Let’s get into the specifics.
The fast fire rated electric roller shutter earns its place in high-rise buildings. It seals off the fire source at stairwells or elevator lobbies and gives people a safe path out. In mid-size and large commercial buildings it also works as a fire wall. That role puts it at the center of building fire safety — and it is where the fire rated electric roller shutter advantages show up most. The notes below cover design, use, and installation.
The Fire Rated Roller Shutter: Three Control Methods
In high-rise homes and multi-story public buildings, you control the electric fast fire rated shutter three ways at once: automatic, local manual, and remote from the fire control room. Each method covers a failure mode in the others, so you do not want to run on just one.
How the Automatic Signal Drops the Shutter
The automatic signal starts with smoke and heat detectors on the ceiling on one or both sides of the shutter. The signal reaches the link control box, which sends the execute command to the shutter control box and raises or lowers the fast shutter.
Detector Placement at Elevator Lobbies
At the elevator lobby of a high-rise office or home, fire is more likely on the corridor side than the stairwell side. Put a pair of smoke and heat detectors on the corridor side, and one smoke detector on the inner elevator side. The two smoke detectors work together. When either one senses smoke, the door drops to 1.8 m above the floor. If the fire door between the lobby and the escape stairwell is also a shutter, fit a pair of smoke and heat detectors in the lobby to control that stairwell door too.
Control Voltage and Staged Drops
Watch the control voltage when you design the fire linkage. The shutter link control box is a signal output device; its working voltage is DC 24V, though some makers allow AC 36V and above for extra reliability. So the shutter carries two control voltages: DC 24V and AC 220V.
On a straight run inside one fire zone, one shutter dropping does not break the fire function. Smoke moves fast — after the first shutter drops, if the fire is not contained the smoke reaches the second shutter and drops it as well. A heat detector at that spot triggers the second-stage drop.
Grouping Several Shutters on One Run
When several shutters seal one straight fire-zone run, keep the detectors encoded in groups of three or fewer. When any pair signals, all three drop together. Then one link control box drives one shutter, and the rest sit on the automatic control line. Each shutter control box parallels the one driven directly by the link box.
Starting more than three at once draws a large current, so the relays, main switch, and wiring must scale up — wasteful, and it adds failure points that slow your fixes.
Post-Epidemic Shutter Advantages You Get
The post-epidemic shutter advantages come down to control you can trust when staff levels shift. Remote operation from the fire control room means one operator manages many doors without walking the floor. Automatic drop on detector signal removes the wait for a person. Local manual override covers the case where power or signal fails. Together these give you a fire rated roller shutter that responds the moment it needs to, not when someone happens to notice.
