What a fire shutter is, where the by-laws allow one, how it must close and who is responsible.
A fire shutter is a fire-rated roller shutter that closes automatically in a fire to keep a compartment intact; it is a life-safety system, not a shop shutter with a thicker curtain. Under by-law 136A of the Uniform Building By-Laws 1984, a fire shutter may protect an opening in a compartment wall or floor, or act as a compartment wall, but not for means of escape such as an exit staircase or smoke lobby. It must meet MS 1073: Part 3 or BS 476: Part 22, close by gravity or by motor on a fire signal, and match the fire resistance of the wall, including insulation, except in areas with no intended fire load. The fire consultant, a specialist supplier and the authorities decide the rest; a ClickBina site visit is RM150, waived if you go ahead.
A building is divided into fire compartments so that a fire in one part is held there long enough for people to escape and firefighters to act. Every opening in a compartment wall is a weak point. A fire door protects an opening people walk through; a fire shutter protects a wider opening that has to stay open during normal use, such as the link between two parts of a warehouse, a loading area, a counter opening or the edge of an atrium, and closes when a fire is detected.
It looks like a roller shutter, but it is a tested, certified assembly with its own release mechanism, controls and interface to the fire alarm. An ordinary shop shutter, however heavy, is not a fire shutter. ClickBina's guide to choosing a new roller shutter covers ordinary shutters, and the fire-rated door guide covers doors in compartment walls.
By-law 136A of the Uniform Building By-Laws 1984, as amended in 2021 in the consolidated text published by the Ministry of Housing and Local Government (KPKT), sets out the rules. In summary:
The KPKT text itself warns that it is a model by-law: each state's own by-laws, the approved building plans and the fire authority decide what applies to a particular building. Treat this page as a map, not a compliance ruling.
By-law 136A names three common kinds and requires them to comply with MS 1073: Part 3 or BS 476: Part 22, the test standards the by-law names:
| Type | How it moves | Where it tends to be used |
|---|---|---|
| Vertical fire shutter | The curtain descends from a roll above the opening, like a roller shutter | Wall openings: warehouse links, loading areas, counters, lift lobbies |
| Horizontal fire shutter | Closes across a horizontal opening in a floor | Openings between floors, such as an escalator or hoist void |
| Lateral fire shutter | Runs sideways across the opening | Wide openings where there is no room above for a roll |
Which type, which rating and which details suit an opening is a design decision for the building's fire consultant, confirmed with the authority, not a catalogue choice.
By-law 136A describes two ways a fire shutter closes:
| Gravity-operated vertical shutter | Electrically operated shutter | |
|---|---|---|
| What starts it | The fire alarm system or a fusible link releases the mechanism | The fire alarm system signals the motor |
| How it closes | The curtain descends under gravity at a controlled rate | The motor drives the curtain or leaf closed |
| Power | Once released, the curtain falls by its own weight | Must be backed up by an emergency power supply |
| Cabling | Alarm interface where required | Power and signal cables must be fire-rated |
| Fusible link | Acceptable in some locations | Not required |
The controlled descent matters: a fire shutter that crashes down is a hazard to anyone underneath, which is why the release, the governor or brake and the alarm interface are tested together.
By-law 136A also ties the trigger to where the shutter is used:
Search terms such as “fire insulated roller shutter” reflect a real distinction. A fire shutter that protects an opening in a compartment wall or floor must match the wall's fire resistance including thermal insulation, so the far side does not get hot enough to ignite stock or harm people. Only in areas without any intended fire load, such as atrium edges, escalator voids and car park driveways, may the shutter be without insulation. An insulated fire shutter is heavier and more complex, which affects the structure above, the headroom and the motor or release gear.
A closed fire shutter can hide an exit or a directional sign. By-law 136A requires exit directional signage with an arrow and the word “KELUAR” to be painted or pasted on a fire shutter or smoke curtain to redirect occupants to the nearest exits where the activated shutter obscures the exit or sign. The signage must be reflective, with letters at least 100 millimetres in height. Check this is included when a shutter is installed or replaced.
A fire shutter sits inside the building's fire strategy, so the roles are the same as for other fire systems. The fire consultant or submitting person decides where shutters are needed, their type, rating and trigger, and makes the submission. A specialist fire shutter supplier provides a tested assembly and installs and commissions it with the fire alarm contractor. Bomba and the local authority review and approve, and inspect where required. ClickBina's commercial renovation permit guide notes that anything affecting escape routes or fire-rated compartments needs Bomba review, and the fire safety equipment guide covers the related alarms and extinguishers.
The builder's part is the opening itself: a structure above that can carry the shutter, straight and fire-stopped reveals, a clear path under the curtain, and making good around the frame without breaking the compartment.
A fire shutter that cannot close is worse than none, because everyone assumes it will. The common problems are simple: stock, racking or a trolley parked under the curtain; the guides damaged by forklifts; the release disconnected because of false alarms; a fusible link painted over; the controls or battery back-up neglected; or a new ceiling, duct or cable tray fixed across the roll. Keep the drop zone marked and clear, report damage at once, and have the shutter tested with the fire alarm by the specialist, keeping the records with the building's fire safety file. ClickBina's roller shutter repair guide explains why a shutter in the fire strategy is a matter for the fire consultant, not a general shutter technician.
