Frequently Asked Questions

Exit Devices & Door Hardware – Q&A

Technically… both! Exit devices are known by many different names including the crash bar, panic bar, panic device, panic hardware, exit device, and push bar. Exit devices are designed to be installed onto the secure side of out-swinging doors.

They restrict access while they provide free egress from the building. Did you know, the exit device was developed in the United States after the loss of many lives in a number of large building fires dating back over 100 years?

There are three common types! Exit devices include the rim, mortise lock, and vertical rod. The most common is the rim exit device which is surface mounted on the secured side of the door.

The mortise lock style exit device incorporates a mortise lock body mounted within the door pocket which offers a clean look. Finally, there is the vertical rod exit device that is available in concealed or surface mount versions. The rods normally connect the device’s push pad to top and bottom latches.

High occupancy exit doors! Exit devices are manufactured for just about every door configuration and prep. Most exit devices can be installed onto wood, hollow metal and aluminum doors as long as the style is compatible with the device.

They are used in high occupancy buildings to meet egress control and must adhere to local building and fire codes as governed by your local AHJ (Authority Having Jurisdiction). In some cases, the exit hardware must also be ULC Listed for fire. Call Union Alarm to learn more about exit hardware.

Panic Bar vs Fire Exit Hardware

Panic Bar Devices and Fire Exit Hardware are two different types of exit devices, and the proper selection is determined by code requirements. A panic bar device is an exit device that is tested for use on a door that is required to have panic hardware but is not certified for use on a fire-rated door.

On the other hand, Fire Exit Hardware includes an exit device that is tested for both egress and fire conditions and is required for use on fire-rated doors where panic hardware is required by code. Fire-rated doors require door closers and UL/ULC listed hardware.

The door must be self-closing and self-latching to keep the doors closed and latched in the event of a fire. These doors are commonly found in stairwells and corridors.

Egress Delay Systems:

Notably,  retail stores will often include exit alarm doors, alarm locks or delayed egress control hardware to prevent door dash thefts and unauthorized egress from the retail floor. By code, all egress hardware must release within 15 seconds of the device being actively depressed and will also sound an audible alarm to notify store staff and managers.

Egress delay systems that incorporate magnetic locks may also require a power supply with fire disconnect relays in order to release the mag-lock in the event of a building’s fire alarm. Furthermore, the public cannot be delayed through a fire exit or fire corridor more than once during egress, and the maximum duration of delay cannot exceed 15 seconds.
