(also PANIC DEVICE) – A door locking or latching mechanism that is designed to always be operable from the inside or EGRESS side of the door by applying pressure on a PUSH BAR or CROSS BAR. Fire rated/labeled PANIC DEVICES have been tested, certified and approved for use on fire rated doors. A PANIC DEVICE can differ in function of the latching features and may be “Rated for Panic” only and not be suitable for use on a fire rated, labeled door opening.

RIM TYPE – Has the locking mechanism and latch located on the inside or push side of the door.

MORTISE TYPE – Has the locking mechanism mortised into the edge of the door. The latch projects from the door edge much the same way as a mortise lock.

VERTICAL ROD TYPE – May be either surface or concealed (referring to the exposure of the top and bottom rods). The latching mechanisms are attached to the ends of rods extending to the top and bottom of the door leaf and are connected to the active case of the device located on the inside face of the door, much like the Rim Type device. When the bar is pushed or depressed the rods are retraced thereby allowing the door to open.
