Panic & Exit Hardware: how the work is done

A pair of doors is its own small project, and not every pair needs the same approach. Some rim-device pairs keep their mullion and latch each leaf independently with no set closing order. Where sequencing does matter, one leaf is chosen as the inactive leaf and closes first, guided by a coordinator so the active leaf's device can seat properly into the strike or into an astragal on the inactive leaf. Removing a centre mullion calls for a compatible replacement arrangement on each leaf, which can matter for wheelchair access or for moving equipment through.

Is this door part of a pair?

Single doors and pairs get assessed differently from the first look. On a pair, the locksmith checks whether a mullion currently splits the opening, whether a coordinator is already fitted, and whether the leaves close independently or in a set order. This decides whether the project is a straightforward device swap on each leaf or something larger, such as removing a mullion and fitting a compatible replacement latching arrangement to turn two narrow doors into one wide exit. Getting this right at the assessment stage avoids ordering hardware for a single door when the opening is really two leaves working together.

Mounting the device and fitting the strike

Installation follows the device's own template so every hole lands where the manufacturer intended, rather than adapting the door to a device that does not quite fit. Fasteners are chosen to match what the template and the door's own construction call for, and where the device specifies through-fixings, they run all the way through the door rather than biting into the surface alone. The strike is set and reinforced so it holds the latch securely under normal use. The crossbar or touchpad is aligned so it sits at a comfortable height and releases evenly across its width, not only at one end.

Electrified functions folded into the building's other systems

Any request-to-exit signal, latch retraction or alarm added during the visit now does its own specific job rather than one combined function: an alarm module can sound locally on its own power the moment the crossbar is used, latch retraction lets an authorized signal release the latch for entry, and a request-to-exit signal tells the access-control panel that the pushpad was actuated. None of them alone proves who passed through or from which side, and the exit function itself remains entirely mechanical underneath, so a power interruption still leaves the door able to be pushed open by hand from the inside.
