Smokemaster SM5 moveable smoke curtain

Smokemaster SM5 automatic smoke curtains prevent the movement of smoke and heat from one area to another in a fire by channelling or containing the smoke and heat. They conform to EN 12101-1 and have both a D120  and a DH 120 rating. Smokemaster SM5 smoke curtains are well suited to most industrial and commercial buildings as they are unobtrusive, moving to their active position only when needed.

  • High performance - Designed to operate for 1,000 cycles at normal ambient temperatures in the range from 0⁰C to 60⁰C, and to withstand hot air and smoke at temperatures up to 600⁰C for up to 120 minutes once only.
  • A wide range of options – Smokemaster can 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 page by clicking the tab above for further information.
  • Certified performance - Smokemaster is CE marked. The D120 curtain material achieves a resistance to smoke at 600°C for a minimum of 120 minutes. The DH120 curtain material achieves a resistance to heat for a period of 120 minutes, following the time-temperature curve in EN 1363-1 with a temperature of 1049°C at the end of the test. All types of material achieve class A2-s1, d0, in accordance with BS EN 13501-1.
  • Configurations and sizes - Smokemaster is available either as a 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. Standard single roller curtains are available between 1500 to 5000mm in length, and drops are between 500 and 8000mm. A requirement for lengths greater than 5000mm will be met by installing either double horizontal or double vertical units. Special units with drops of up to 15000mm are available.
  • Drive types - With the G (Gravity) version smoke curtain, the curtain falls under gravity in a controlled manner to a predetermined level either on receipt of a signal or on loss of power. With the D (Drive) version smoke curtain, the curtain drives down in a controlled manner to a predetermined level on receipt of a signal. Either type of smoke curtain can be driven down to an intermediate position, for instance over an escalator, where it is held at that position for some time before descending further.
  • Control system - Smokemaster 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 control panel. The system is fully protected and fail-safe to avoid the need for fire rated cabling. An optional 30 minute time delay maintains units in the raised position in the event of a temporary interruption to the power supply via the control system’s uninterruptible supply system. If power is not returned, units will descend to the down / default position after a time lapse in a controlled fashion.

FM1 fire resistant curtains

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.
  • A wide range of options – A FM-1 fire curtaincan 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. 
  • 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 housing 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 manufactureFM-1 fire curtains are manufactured under the ISO 9001 quality standard by Colt.
  • Design service- Colt provides a pre-order design service. Please contact Colt for more information relating to the application, specification, installation or servicing of FM1 systems.
