Panic Bar Installation

What a Panic Bar Does and When Codes Require One

A panic bar is a horizontal touchpad or crossbar mounted across the inside of an exit door. Pressing anywhere along it retracts the latch, so the door opens without twisting a knob or knowing which way a lever turns. Devices listed under UL 305, the panic hardware standard, must open with modest force so a crowd pressing against the door still gets out.

Building codes commonly require panic hardware on doors serving assembly or educational spaces above a certain occupant count - often 50 people under the International Building Code. Quality also matters: ANSI/BHMA grades exit devices, and Grade 1 units are built for heavy daily use on schools, storefronts, and back-of-house exits.

Rim, Mortise, and Vertical Rod Exit Devices

The right device depends on the door and frame:

• Rim devices mount entirely on the door surface and latch into a strike on the frame. They are the most common and simplest to install on single doors.
• Mortise exit devices use a mortise lock case cut into the door edge. They suit heavy-traffic openings that need a stronger latch.
• Surface vertical rod devices latch at the top and bottom of the door - the usual answer for pairs of doors with no center post (mullion).
• Concealed vertical rod devices hide the rods inside the door or in aluminum storefront stiles for a cleaner look.

Older crossbar styles still exist, but modern touchpad designs are smoother and easier to maintain.

Fire-Rated Doors and the Dogging Feature

Two details trip people up. First, dogging: many panic bars have a hex-key or key-cylinder dogging feature that holds the latch retracted, so during business hours the door works as a simple push/pull. Second, fire-rated doors are different. A fire door must positively latch to hold back smoke and flame, so it takes fire exit hardware - devices tested to a fire standard - and mechanical dogging is not allowed on them. If your door has a fire label on its edge, that label decides which hardware is legal, not looks or preference.

What Professional Installation Involves

Installing an exit device means more than screwing on a bar:

• The device is sized to the door width and often cut down to fit; templates locate the mounting holes and latch height.
• Strikes, rods, and latches must align so the door latches every time it swings shut - a panic bar that does not latch is a security hole.
• Outside access is set up with trim: a keyed lever, a pull with a cylinder, or exit-only with no outside hardware.
• Electrified options exist, including alarmed devices that sound when the bar is pushed and electric latch retraction for access control systems.

A locksmith can look at your door material, fire label, and traffic level and recommend a matched device. Call (916) 913-5080, describe your door and building use, and confirm whether this service fits before anything is scheduled.

Frequently Asked Questions

Can a panic bar go on any exit door?

Most doors can take one, but the device must match the door. Hollow metal and solid wood doors take rim or mortise devices; aluminum storefront doors with narrow stiles usually need a concealed vertical rod device made for that stile width. Fire-labeled doors require fire exit hardware, not standard panic hardware. Door width matters too - devices are sized and cut to fit, and very narrow doors limit the options.

What is dogging, and why is it banned on fire doors?

Dogging holds the latch retracted so the door acts as a push/pull during open hours - handy for storefronts and busy corridors. It is done with a hex key or, on cylinder-dogging models, a standard key. Fire doors must positively latch every time they close to block smoke and flame, so mechanical dogging is prohibited on them; fire exit hardware is built without it.

Can I still lock a panic bar door from the outside?

Yes. The egress side always opens with one push - that part can never be locked - but the outside is controlled by the trim you choose: keyed lever trim for regular entry, a pull with a key cylinder, or exit-only with no outside hardware at all. Some devices also accept electrified trim so a keypad or card reader controls entry.
