A fire curtain is used where, if there is a fire, it is necessary to create a temporary barrier within an opening which seals off the area on fire. The curtain descends and prevents any fire and smoke from spreading from one area to another. It also allows people access to protected escape routes without any loss of fire resistance.
A FM-1 fire curtain comprises a flexible fire-resistant fabric which is wound around a circular tube. Upon receiving a signal from the fire alarm system or on loss of power the curtain automatically unwinds to its operational position.
FM-1 fire curtains have been tested as fire barriers in accordance with EN 1634-1, providing protection for a defined period and at a defined maximum temperature.
High and certified performance - FM-1 fire curtains have been tested as fire barriers for either 60, 120 or 180 minutes resistance, in accordance with EN 1634-1. They have E60-C, E120-C and E180-C ratings in accordance with EN 13501-2, thereby achieving an integrity rating for either 60, 120 or 180 minutes.
A FM-1 fire curtain has achieved a successful a continuous life cycle test (10,000 cycles) in accordance with DIN 4102-18.
The E120-C and E180-C versions also have class EW 30 in accordance with EN 13501-2, which demonstrates that the fabric re-radiates only a limited amount of heat.
No power needed to operate it – A FM-1 fire curtain unwinds to its operational position under the influence of gravity in a “gravity fail-safe” manner without the need for power.
Compact and low in weight – A FM-1 fire curtain is lightweight and compact, which enables it to be installed easily in a place with space constraints such as a false ceiling. Such a roller fire curtain is much more unobtrusive than a roller shutter with a comparable performance.
A wide range of options – A FM-1 fire curtain can easily be adapted to the physical constraints of the building. All system components – headboxes, fabric, bottom bars, drive systems – can be customised to your needs. See our options tab and leaflet for further information.
Easy to install and maintain - A FM-1 fire curtain is delivered in modular form and as such is easy to install. The bottom of the headbox is closed off with a panel which also allows the entire length of the system to be accessed for servicing.
Virtually invisible when rolled up –There are no visible fixings either on the underside of the headbox or on the bottom bars. The headbox, the bottom bar and the side guides can be powder-coated to a RAL colour to blend in with the building.
Can accommodate thermal movement – All major components are fitted with expansion joints, which enables the curtain to function at high temperatures.
Robust manufacture – FM-1 fire curtains are manufactured under the ISO 9001 quality standard by Colt.
A FM-1 fire curtain is available either as single unit, or as either a double horizontal or a double vertical unit for continuous runs, where fabric is overlapped to form a continuous barrier.
Overall curtain lengths for single units are available from 1000 mm to 5000mm, and drops are available from 500 mm to 6000mm.
Double vertical and double horizontal units are unlimited in length and drops are available from 500 mm to 6000mm provided that curtains overlap.
The fabric is fire-resistant and comprises one of the following options:
There are three bottom bar options. All are virtually invisible when the curtain is rolled up.
A side guide system provides a seal between the sides of the curtain fabric and the walls, ensuring that any positive or negative pressures created by a fire will be resisted by the curtain and so that it won’t deflect significantly. Side guides can be integrated either into or onto a wall / soffit or into a recess / niche. The FM-1 side guide roller system has been designed to ensure that the curtain will move to its closed position easily even when there are significant air velocities around the curtain.
A FM-1 fire curtain can be made capable of operation as an integrated part of a smoke control and fire management scheme, with emergency power units and the facility to interface directly with a fire alarm system.
There are 2 control options.
Option 1 – basic system
The curtain installation is fully protected and fail-safe to avoid the need for fire rated cabling. The control system maintains the curtains in the raised position in the event of a temporary interruption to the power supply if an optional uninterruptible power supply (UPS) has been supplied and connected. If power is not returned, the curtains will descend to the down / default position for a predetermined period (nominally 30 minutes) in a controlled fashion.
If signalled to descend during this period, the curtains drop under the force of gravity in a controlled manner to their fire operational position in a fail-safe manner. Once the curtains have descended, they can then be driven up.
The panel also has a switch for service and maintenance purposes, so that the installation can be individually checked without having to interfere with the FAS.
Option 2 – advanced system
The control panel is as described above, but with additional features and functions. It has been tested to BS 8524. It is designed to meet the requirements of the pr12101-9 product standard. It has a local power supply system to maintain all control functions over a period of at least 72 hours, meeting the requirements of EN 12101-10.
The panel is modular and can be configured to provide any of the necessary functions needed for a project.
It monitors cables for wire-break and short circuit in accordance with EN 12101-9. It can function as a standalone system when connected to smoke/heat detectors and break glass push buttons. It has 3 indication lights and a buzzer and push buttons for manual operation.
The panel also can include various options such as:
We provide a pre-order design service. We also offer complete project management, installation, wiring and commissioning, which means that we take complete responsibility to ensure that the product is in full working order within one package of works.

Electrically operated automatic fire curtain, which seals off an area which is on fire, thereby preventing that fire from spreading from one area to another.
The curtain falls under gravity in a controlled manner to a predetermined level in a fire situation or on loss of power.
The unit is equipped with side guides which provide a seal between the curtain fabric and the building, ensuring that any air pressures created by a fire will be resisted. They can be fitted:
