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.
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.
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.
Addressable smoke shaft door operator for smoke ventilation from corridors, lobbies and stairwells into smoke shafts. Designed to allow the passage of smoke from such areas into smoke shafts, by opening the shaft door(s) on the fire floor and keeping any shaft doors on the non fire floor(s) closed.
Each unit individually addressable and controllable, and able to communicate back to a central panel. Each operator includes actuator, communication module, local reset switch and adjustable fixing brackets which allow release of the mechanism from the corridor if necessary. (Front fix option only).
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.
Actuator tested and has successfully completed 10,000 operations at full design load. Incorporating a 230 V ac or 24 V dc electric chain drive motor. Suitable for use where a maintained mains electrical supply is installed in the building.
