Panic & Exit Hardware: inside the visit

Electrified exit hardware adds a layer without changing the basic behaviour of the door: a person inside can still leave under one motion of the hand, every time. A request-to-exit switch tells an access-control panel that the pushpad or crossbar was actuated, usually paired with a door-position contact so the panel can also tell a normal exit from a forced or propped door. Electric latch retraction lets a fire-rated opening behave like a push-pull door for staff, provided it relatches automatically on a fire-alarm signal, since that kind of door never carries a mechanical dogging function. An alarm module sounds when the device is used.

Accessibility and reach at the door

The assessment also looks at who has to operate the door: mounting height, the force needed to release the touchpad or crossbar, and whether the outside trim's lever or pull suits someone with limited grip or reach. A door that meets a code minimum can still be awkward for the people who use it every day, so this check asks not only what is required but what will work well for the staff and visitors who pass through the opening.

Handling a pair of doors

On a pair, a coordinator is fitted only where the hardware needs the leaves to close in a set order, letting the active leaf's device seat into the strike or into an astragal carried on the inactive leaf; many pairs latch independently and skip this step entirely. Where the plan calls for one wide exit instead of two narrow ones, the centre mullion is removed and vertical-rod devices are fitted to each leaf instead, arranged so both close and latch reliably. Either way, both leaves are tested together, not only on their own, before the visit is called finished.

A door that opens under one motion, every time

What the space has afterward is straightforward: anyone inside can leave through that door with a single push on the crossbar or touchpad, no key, no second step, no need to remember which way a lock turns. Staff can be shown the motion once and it stays intuitive, because that is exactly what the hardware is built to do. Outside, entry still works the way it was set up to, through the trim chosen for that door, entirely separate from the exit function inside.
