A fire curtain is used where, if there is a fire, it is necessary to create a temporary barrier within an opening that 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 that 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.
There are three bottom bar options. All are virtually invisible when the curtain is rolled up.
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:
The fabric is fire-resistant and comprises one of the following options
Option 1 - basic system
Curtain installation fully protected and fail-safe to avoid the need for fire rated cabling. Curtains maintained 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, curtains 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.
Panel has a switch for service and maintenance purposes, so that the installation can be individually checked without having to interfere with the fire alarm system.
Option 2 – advanced system
As above but with additional functions. Control panel tested to BS 8524. Designed to meet the requirements of the pr12101-9 product standard. 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. Modular build to accommodate the specific needs of the project. Monitors cables for wire-break and short circuit in accordance with EN 12101-9.
