In providing the complete rooflight package, our Mardome range includes automatic opening smoke clearance domes which provide an effective means of allowing smoke and hot air to vent out in the event of a fire, particularly when combined with low level vents. Mardome Trade, Ultra and Hilite NEW AUTUMN 2010 can be configured to operate as smoke clearance units. SV30 and SV90 automatic opening domes open to 30˚ and 90˚ respectively, to facilitate the maximum possible ventilation. Typically these automatically opening rooflights function as part of a smoke clearance system although they can also be configured to operate manually (e.g. via a wall mounted switch). Actuators operate from a 24v DC supply and are usually connected to a separate control system (for smoke clearance). Polarity to the actuators needs to be reversed to open or close, and the SV90 includes magnetic latches which require a permanent 24v supply.
