Controls | Control system.Guidance for specification option: It is recommended that Mardome Smoke Vents are connected to the Smoke Vent control panel available from Access Building Products Ltd. The control panel is designed to be used with the actuator of the Mardome Smoke Vent and provides a battery backup and additional line monitoring functionality. A Mardome Smoke Vent can be installed alongside other EN 12101-10 compliant control systems but Access Building Products Ltd cannot provide technical support concerning the control of the product and do not keep a list of compatible control systems. Installing with an alternative EN12101-10 control system will not affect the guarantee of the product. |
Initiation | Guidance for specification option: Control panel can be activated from: Manual override switches, by dedicated smoke detectors or through integration with existing smoke detection and or fire alarm systems. |

Accessories | Not required.Control panel system.Guidance for specification option: The EN12101-10:2005 approved and certified Mardome Smoke Vent Control Panel System is available in 5A and 8A options and comes with a built-in comfort switch at the front. See TB286 for more information. Fire switch.Guidance for specification option: The Mardome Fire Switch (IP40) is developed to be used together with the Mardome Smoke Vent Control Panel System. Its function is to open the Smoke Vent and activate the alarm. It comes with a breakable glass and is available in orange colour as standard. Fireman's priority switch.Guidance for specification option: The Mardome Fireman’s Priority Switch (IP40) is developed to be used together with the Mardome Smoke Vent Control Panel System. Its function is to open/close the Smoke Vent without influencing the alarm situation. It comes with a breakable glass. Smoke dector.Guidance for specification option: The Mardome Smoke Detector allows early fire detection with a visual ‘release’ display. It is available in white as standard. Wind deflectors.Guidance for specification option: Wind deflectors manipulate the air flow over and around the AOV, helping increase the aerodynamic free area (AA) of the AOV. In all cases the wind deflectors increase the Aerodynamic Free Area, meaning a smaller AOV with wind deflectors can match or out perform a bigger AOV without. This is particularly useful when needing to achieve an Aerodynamic Free Area of more than 0.70 Aa m2 in a stairwell as per the requirement of EN 12101-2. |
