Electromechanical door release 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.
Its robust mechanism ensures doors stay locked when not in use but open when required. Its modular design allows ease of installation. A local control module and power supply removes need for fire rated cables / UPS / battery backup systems.
