Useful Fire Rated Door

- Mar 03, 2019-

All fire doors have an additional safety feature – they must be self-closing and self-latching. This means that in the event of a fire, all of these doors will close and latch without a person's help. This is accomplished through the use of a closer or spring hinge and a fire-rated lockset or exit device. Also, fire doors can never be held open with a door stop or any device other than a magnetic hold. The magnetic hold must be tied to the fire alarm so the door will close automatically during a fire. Electric locks used on fire doors must be fail-safe, never fail-secure – that is, the doors will automatically unlock during a fire to save lives rather than remain locked to protect property.
