Multi-leaf overhead telescopic door
EI 30 EI 60 EI 120
Designed per custom specifications
The Marc-O vertical sliding door comprises the following basic components: the door leaf, two guide rail sets, the counterweight with pulleys and carrier cables/belts, and horizontal and upright labyrinth sealing components.
The door leaf (60 or 100 mm for EI120 or EI30/EI60, respectively) comprises upright panels which can be 400 to 1200 mm wide, two side profiles, the bottom profile, bracing hardware and cladding of galvanized sheet steel.
Each door leaf panel features a modified, fire-resistant mineral wool core in class A1 with internal reinforcement formed by steel bars (a solution protected by European Patent no. W 02/079600A1).
The door leaf runs in two guide ways installed on both sides of the installation opening.
The guide rail and shaft box fascias are available in galvanized sheets coated in three basic colours, RAL 7035, 9002, 9010 and 7016
The overhead doors can be optionally provided with a man door. The standard man door version is provided with a lever tumbler lock, double-sided door handle hardware and spring-return hinges
The Marc-O overhead fire doors are intended for regulatory-compliant separation of fire zones inside and outside of buildings and across handling system flows.
The product is mainly intended for manufacturing facilities, warehouse rooms, and cultural event venues, which may include theatres and opera houses. It is a perfect wall closure solution whenever the installation clearance can only be provided above the wall opening.
The overhead doors can have optional man doors; if the parking space beneath the overhead door is limited, the door can have a 2 or 3-section telescopic leaf.
The basic door version has the leaf closed by gravity-assisted movement of the counterweight. The door can be held open with an e-mag holder wired to the on-site fire alarm control panel. In the event of a fire alarm, the control panel releases the e-mag holder and the door leaf closes the passage between the fire zones. The door can be opened manually. The door can be optionally provided with an electrical drive unit which operates the door to open and close. Small door sizes can be delivered without a counterweight.
