Electromagnetic Door Holders
These systems are primarily engineered to hold open self-closing fire and smoke barrier doors under normal conditions and automatically release them during an emergency.
Fire System Integration: They function independently or connect directly with fire and smoke detector alarms to automatically release the door when a hazard is detected.
Holding Force: They deliver a typical high holding force up to 80 lbs, preventing accidental closure during daily operations.
Safety Release Mech: Features a built-in manual release button allowing personnel to manually shut the door at any time, with zero residual magnetism to ensure the door never sticks during an emergency .
Mounting Versatility: Can be flush, floor, or surface mounted, and supports optional extension rods to correct minor door alignment variances.
