The Ceasefire Door Hinge is an easily installed, low cost, last line of defense fire protection product that does not require batteries or wires.

Intended to be installed as a top hinge on the various interior doors of a home (e.g., bedrooms, bathrooms, closets), the device functions as a standard door hinge, allowing the door to swing freely as normal.

When exposed to temperatures typical found in the very early stages of a fire, the device activates, closing the door and cutting off oxygen to the fire. The closed door also acts as a barrier from heat and toxic smoke, giving you more time to escape or be rescued.

After being activated, the hinge now acts as a typical spring hinge, continually acting upon the door with a gentle closing force, while allowing for normal ease of re-opening of the door.
