Panic & Exit Hardware
The new access-control reader at the staff entrance works fine going in, but nobody has sorted out the door's exit side, and right now a card reader and a pushbar exist as two separate ideas.
In plain words
Which device goes on a door depends on what the door already is. A single interior door usually takes a rim exit device and a simple pull or lever outside. Listed fire-exit hardware covers many tall, narrow-stile and fire-rated openings too, so a mortise or vertical-rod device is chosen for its latching arrangement or the door's own preparation, not from height or fire rating alone, and a fire-rated opening can never be held open by a mechanical dogging function. Reading the door correctly before ordering hardware is most of the job; fitting it well is the rest.
How the visit goesAfter the fit-out, the gym floor now holds more people than the old office space ever did, and the exit door at the back still has the same turn-lock it had when the room held desks.

How the visit goes
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.
Labelling, signage and the dogging key
Any signage the opening needs, such as a label identifying the door as an exit or noting an alarm, is fitted alongside the hardware rather than left for later. Where the device carries a dogging function on a standard opening, the key or keyed cylinder for it is handed to whoever the building's management names as responsible, along with an explanation of when dogging is appropriate; on any door that sits in a fire separation, mechanical dogging is left off the device entirely and is never installed as a management choice.
Room to grow into the next change
If the space changes use again, adds seating, or the occupant load creeps upward with a future renovation, the hardware fitted now is already suited to a use that requires it, rather than something that will need revisiting the moment the room grows busier. Keeping a note of the occupant load the current hardware was specified for means a future change can be checked against that number before it becomes an inspector's finding rather than a planned upgrade.

What affects the quote
Single door or a pair
A pair of doors that needs ordered closing calls for a coordinator or an astragal, and one being converted into a single wide exit needs a mullion removed and replaced with vertical-rod devices on each leaf, both of which add work beyond a single-door installation.
Number of openings involved
One door with a single device is the simplest case. A building with several affected exits, such as doors from a stairway plus an assembly-room exit, is quoted as the sum of each opening's own work.
Access to the opening
A ground-floor commercial door is straightforward to reach. An opening behind scaffolding, up a stairwell with no elevator, or in a space still under active construction takes longer to work at.
What to have ready
- Is access control or an alarm system planned for any of these doors?
- Do you want outside entry by pull, lever or keyed cylinder?
- What is the room's intended use and approximate occupant load?
Panic & Exit Hardware: questions
QuestionsHow high should the crossbar or touchpad be mounted?
Exit-device makers publish a mounting range for their own models, and in practice a crossbar or touchpad sits no higher than about 1200 mm above the finished floor. The locksmith sets the hardware inside the maker's range and below that ceiling, allowing for anyone in the space who needs a lower reach, a wheelchair user or a shorter staff member among them.
When does a door actually need this hardware rather than a regular lock?
It comes down to occupancy and occupant load rather than preference. Rooms used for assembly, such as banquet halls, places of worship or gyms, and doors serving a stairway in a busier building, are where this hardware becomes the standard choice instead of a keyed lock on the exit side. A fire inspector or building official is the practical way to confirm whether a specific room has crossed that line.
What happens with a pair of doors instead of one?
It depends on the pair. Some latch independently and need nothing extra. Where the hardware calls for a set closing order, a coordinator lets the two leaves close in the right sequence, letting the active leaf's device seat properly into a strike carried on the inactive leaf, or into an astragal. Alternatively, the centre mullion can be removed and a vertical-rod device fitted to each leaf, turning the pair into one wide exit. Whichever applies, both leaves are tested working together, not one at a time.
