Most fire doors are kept closed at all times, however some doors are held open with magnetic devices and will shut automatically upon the activation of a smoke detector, fire alarm system, or sprinkler system. The movement (opening and closing) of a fire door must never be impaired by a door wedge/chock or other obstacle. The use of chocks in this manner is illegal and will incur a penalty. If a unit owner wishes to have their fire door open, they should contact their service agent to install a device that, on the activation of a smoke detector in their unit, or in the common area of the building, will release the fire door allowing it to automatically close fully
