Doorman fire damper door operator

Doorman is an electromechanical door release operator, designed to provide a safe and reliable actuation system for use in smoke ventilation of commercial and residential properties. It has been designed to be applied where doors are used as part of a smoke control scheme to allow passage of smoke and fume in corridors into smoke shafts. It is manufactured under the ISO 9001 quality and ISO 14001 environmental management standards.

What it consists of

Doorman consists of an individually addressable and controllable door actuation system linked to the fire alarm system via a Colt OPV system. Each Doorman fire damper includes the door operator and communication module, all packaged to allow easy installation on site.

It is designed to be installed onto the back of a certified fire door of a minimum 790mm width. It is suitable for fire doors requiring up to 30 Nm opening and closing torque, as Certifire Technical Schedule TS 21: Smoke Door Seals.

How it works

During normal, non-fire conditions, the system is in its monitoring mode. In the event of a fire, the Colt OPV panel operates the Doorman fire damper on the specific fire floor in conjunction with the roof mounted ventilator at the top of that shaft allowing smoke to be extracted from the fire floor. Any shaft doors on the non-fire floor(s) are kept closed.

Features and benefits

  • Its robust mechanism ensures doors stay locked when not in use but open when required.
  • Its modular design allows ease of installation and flexibility in location of components. It is supplied completely assembled, and simple installation onto the rear face of a door.
  • There’s one standard size for all doors, and that is 790mm wide (the door height would then need to be 2150mm to meet Approved Document B). A "ColtShaft" option allows for the narrower doors that are used on such systems, which is suitable for doors 600mm wide and above.
  • It has been exhaustively tested in-house.
  • There are 230V AC and 24V DC drive options.
  • A local control module and power supply removes need for fire rated cables / UPS / battery backup systems.
  • A design, install and commission service – We provide a pre-order design service. We also offer complete installation, wiring and commissioning, thus all the components are contained within one package of works and under one company's responsibility.
