Panic & Exit Hardware in Cambridge
Someone at the front counter always has to unlock the side door by hand before the lunch rush, because the round doorknob out there was never meant to be an exit for a room this size.
Panic & Exit Hardware
In plain words
A code trigger usually starts the conversation: an occupant load over a threshold, a fire inspector's note, or a new use for a room that used to hold far fewer people. From there the visit works out which openings are affected, what device and trim suit each one, and whether a pair of doors needs a coordinator or a mullion removed. The installation follows a template, and every device is tested for release force and full latch engagement before the visit ends, with a written record of what went on the door for anyone reviewing the space afterward.
How the visit goesA padlock went on the stockroom's back door years ago for security and nobody has thought about it since, until the walkthrough this week pointed out that the same door is the room's only other way out.

How the visit goes
How the space is actually used day to day
Beyond the code question, the locksmith asks how people actually move through the door: whether it is propped open during business hours, whether deliveries come through it, whether staff dog it open for a shift and forget to release it afterward. These habits shape which options make sense, such as a keyed dogging cylinder that limits who can hold the door open, or an alarm module that tells staff the moment a door meant to stay closed has been used.
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.
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.

What affects the quote
Same fees day, night or weekend
1Weatherproofing for an exterior opening
An exterior device, strike and trim built to handle temperature swings and moisture cost more as hardware than an equivalent interior-only set, and the quote reflects that difference in the parts themselves.
2Door and frame condition
A door that has sagged, a frame that has shifted, or a strike pocket that no longer lines up needs correcting before hardware is fitted, which adds its own line to the quote.
3Access-control integration
Where the door ties into an existing access-control panel, coordinating the exit hardware's signals with that system takes planning with whoever maintains it, which the quote accounts for separately from the device itself.
Panic & Exit Hardware: questions
Can a padlock or extra deadbolt stay on a door that has this hardware?
No additional fastening should stay on an exit door that does not release the same way the primary device does. A hasp, padlock or separate deadbolt added at some point for extra security is a common finding on an older door, and removing or replacing it with something that releases under the same push is part of bringing that opening back to a single, reliable exit.
Who is responsible for keeping the hardware compliant?
The building owner or the party the owner assigns, often a facilities manager, is responsible for keeping exit hardware in working order and for the fire door assembly testing that goes with it. A locksmith installs and services the hardware and can keep records on the owner's behalf, but the ongoing duty to maintain the assembly sits with whoever holds the building.
Can I still lock the door from outside?
Yes. The releasing device only governs the inside of the door; the outside gets its own trim, a pull, a lever with a cylinder, or a keyed cylinder alone, chosen for how that door is entered. Locking or unlocking that outside trim has no effect on the inside crossbar, which always releases the latch under a push, so entry security and exit function are handled as two separate questions.
