The MDH-FEM288x series of fire and smoke door magnetic holders have a titanium alloy finish and an elegant appearance. They are usually installed on fire and smoke doors in projects where doors are required to be held in the open position for both pedestrian and general traffic. The devices have to be linked into a fire/smoke alarm system.
When an alarm occurs, power is removed from the devices and the doors are returned to the closed position, preventing the spread of fire and/or smoke to other areas. The devices are fire tested to a rating of 4 hours and are supplied as either 12 or 24Vdc.
