Application

The principal functions of a fire-separating barrier such as a Fire Curtain FM1 fire curtain are:

  • To maintain any compartmentation of buildings needed to limit the spread of fire and smoke; and
  • To allow access to protected escape routes, without any loss of fire resistance, and to limit smoke entry into these routes, e.g. protected corridors and protected shafts.

In the event of fire, such a barrier can also be partially deployed to control the movement of smoke within a building, prior to being fully deployed as a fire barrier.

Description

A Colt Fire Curtain FM-1 is designed to seal off an opening between two areas where there is a fire and to prevent that fire from spreading from one to the other area. It operates automatically when connected to a suitable control and power system and correctly specified, commissioned and installed.

The fire curtain has fixing options to suit all types of walls and can be integrated either into or onto a wall or into a recess. It remains hidden until required.

The fire curtain comprises a flexible heat resistant fabric which is impervious to smoke and hot gases, wound around a circular tube and positioned within a compact galvanized steel headbox. Upon receiving a signal from the fire detection system the curtain automatically unwinds to its operational position under the influence of gravity in a 'gravity fail-safe' manner without the need for power.

Applications:

The principal functions of a fire-separating barrier such as a Fire Curtain FM1 fire curtain are:

  • To maintain any compartmentation of buildings needed to limit the spread of fire and smoke; and
  • To allow access to protected escape routes, without any loss of fire resistance, and to limit smoke entry into these routes, e.g. protected corridors and protected shafts.

In the event of fire, such a barrier can also be partially deployed to control the movement of smoke within a building, prior to being fully deployed as a fire barrier.

Motor drive unit:

The fire curtain commences movement either upon initiation or upon any power or system failure and moves to the fire operational position.

The 48V DC motor drive unit includes a gearbox assembly and electronics which control the speed of descent, overload shutdown, switching over in holding current, switching off and motor protection. The unit is pre-wired to enable simple 'plug and play', thereby reducing on-site installation time.

Controls and operation:

The control system ensures that the curtain stays in place when rolled up. In the event of mains power failure, if an uninterruptible power supply (UPS) has been supplied and connected, the curtain remains retracted for a predetermined period (nominally 30 minutes). If signalled to descend during this period, the curtain drops under the force of gravity in a controlled manner to its fire operational position in a fail-safe manner. Once the curtain has descended it can then be driven up.

The curtain descends in a controlled fashion with a velocity of 0.15 m/s in order to avoid dangerous guillotine/ free-fall deployment.

The control system can be configured to allow the curtain to drop to an intermediate position where it can be held for some time before descending further. Once the curtain has descended it can then be driven up at a roll-up speed of 0.06 m/s.

Fire-rated cabling is not required between the control panel and the curtain.

  • Power supply for 24V DC output for direct connection to the fire alarm system.
  • Enables a scheme of fire curtains to be made capable of operation as an integrated part of a smoke control and fire management scheme.
  • A fascia-mounted key switch for manual operation of the connected curtain(s). Can be connected to a 230V uninterruptible power supply to maintain the curtains in their raised positions in the event of a temporary interruption to the power supply.

Bottom bar:

  • A bottom bar comprising two sections of folded 2 mm galvanized angles attached to the lower edge of the curtain material ensures that the curtain unrolls correctly and stays stable, level and fully extended when rolled down whilst reducing any deflection which might be caused by air currents.
  • When the curtain is rolled up, the bottom bar provides a clean finish. Can include either a fabric loop closure arrangement to ensure a tight seal even with uneven floors, a stainless steel spring in order to accommodate any unevenness in the soffit or a simple channel arrangement. See below for the detailed options.

Side guides:

The curtain is always equipped with side guides which ensure that the curtain does not deflect significantly. See below for the detailed options.

Delivery:

All single headbox and single roller units may be completely pre-assembled in the factory. Side guides ordered are delivered separately. All fixings are provided. Otherwise the unit is supplied in partially pre-assembled modules for on-site assembly.

Installation:

  • Installation is by Colt-certified installers and commissioning engineers working to quality standards in compliance with the requirements of prCEN/TR 12101-4 and BS 7346-8.
  • The design and dimensioning is carried out according to local constraints and the temperature class of the system.
  • The unit is installed using special brackets either for wall or ceiling mounting.

Standards:

Fire Curtain FM1 fire curtains are tested as fire barriers for 60, 120 or 180 minutes resistance, in accordance with EN 1634-1. Therefore they are available with E 60-C1, E 120-C2, E 180-C2 and EW-30 fire resistance ratings according to EN 13501-2, providing protection for a defined period and at a defined maximum temperature. They have passed a 10,000 cycle reliability test.

Manufactured under the ISO 9001 quality standard.

Headbox:

- SI:

The fire curtain comprises one 1.25 mm thick galvanized steel headbox assembly containing a single 70 mm diameter roller, fabric and bottom bar.

- DH:

The fire curtain comprises a series of 70 mm diameter rollers mounted next to one another in a horizontal configuration to form a continuous run of curtains, set within a 1.25 mm thick galvanized steel headbox. The fabric of any two adjacent curtains is overlapped, thereby preventing any gaps between them and forming a seamless barrier during a fire. This configuration is especially suited to where ceiling heights are constrained.

- DV:

The fire curtain comprises a series of 70 mm diameter rollers mounted above one another in a vertical configuration to form a continuous run of curtains, set within a 1.25 mm thick galvanized steel headbox. The fabric of any two adjacent curtains is overlapped, thereby preventing any gaps between them and forming a seamless barrier during a fire. This configuration is especially suited to when gaps have to be minimised in cases where curtains abut up against walls.

Bottom bar:

- ID:

Includes a fabric loop closure arrangement to ensure a tight seal even with uneven floors when the curtain is lowered.

- UK:

The bottom bar has a stainless steel spring in order to accommodate any unevenness in the soffit when the curtain is raised.

- U:

The bottom bar has a simple channel arrangement that simply rests against the soffit when the curtain is raised.

Side guides:

- FR:

The rollers mounted on the sides of the curtain ensure that it is fixed tightly into the side guides and so provide additional stability.

- FS:

The loops attached to the side of the fabric work together with the vertical 20 mm diameter guide tubes to hold the fabric tightly within the side guides, and so provide additional stability. As a result there is minimal air leakage around the edge of the curtain.

Side guides can be designed either for installation into a wall opening, onto a wall opening (face fixing) or into a recess in the wall to give a flush finish.

Colour/ finish:

One or more components can be additionally powder coated. Consult with Colt for further details and RAL colours available.
