Lockwood FD484 for Double Doors with Coordinator and Electromechanical Hold-Open Device

The FD484 is designed for applications such as hotels and hospital corridors, where both door leafs are usually kept open. The FD484 is designed for double doors with hinge distance 1100-2100 mm.

In normal day use both doors are open. The hold open angle for inactive door can be adjusted 70°- 130 °. The hold open device keeps the inactive door open whereas the coordinator keeps the active door open. The maximum hold angle for the active door is 150°. When the power is switched off, i.e. when the smoke detectors react to smoke, the inactive door closes first and when it is almost closed, the active door starts to close. The Hold open device includes adjustable hold open force. Current consumption 60mA (24 VDC).
