[jbowman]

When installed panic hardware shall be mounted at a height not less than ____ inches?

a. 44 inches
b. 24 inches
c. 30 inches
d. 42 inches
e. 36 inches

I have to go with 42" Our building code only specifies NOT higher than 47" and I guess they forgot to talk about min height.

[Marcel R. Cyr]

Good trick question John.

Code minimum allowed and standard mounting heights are two different answers that are not easily interchangeable for Commercial hardware.

Under normal construction techniques those that selected 36" would be correct. However special considerations are made for Day Care centers and facilities that provide services or housing to shorter individuals. In these facilities a minimum may be as low as 24-inches.

APPROVED PANIC HARDWARE

The USBC requires that panic hardware consist of a door-latching assembly incorporating an activating device (typically a horizontal bar or push pad) that causes the door to unlatch when a force is applied in the direction of egress travel. Approved panic hardware must meet the following specifications:

1. 1. Have a maximum unlatching force of 15 pounds and be capable of one handed operation without special effort or knowledge.
   
2. 2. On standard swinging exit doors the activating portion of the releasing device shall extend at least one-half (½) the width of the door leaf (see example below).
   
3. 3. On balanced exit doors the activating device must be of the push-pad type and shall

1. not extend more than one-half (½) the width of the door leaf from the latch side.
   
2. 4. The activating device must be mounted at a height greater than 36 inches but less than 48 inches above the finished floor.

Just thought I would add this in to not cause any confusion.

Although fact that a minimum mounting height for panic devices may be 36",
Most all Commercial Hardware is installed at 41" to the center of the push bars.

Where a vertical rod device may be used, the centerline height would be at 39 & 13/16 off of finish floor. Any other height would cause the top rod or bottom rod to be short or too long.

Residential and light Commercial usually have hardware preparations on the frames and doors set up for 36" centers.

Full commercial hardware, doors and frames are always preped for 41" center hardware mounting.
Commercial hardware will not mix with Residential doors and frames unless custome ordered. Everything from templateing and mounting are usually different.

Higher the better, not exceeding the recommended code in your area.
44" on center of the bar.

[Kenneth Lott]

24"is also recommended for people confined to Wheelchairs.

Ken,

I've been looking for this information. If you don't mind would you share your reference?

I would be curious also John, for I have never heard of a panic device installed at 2'-0" AFF..

Mounting Heights

Allowable mounting heights for exit devices are the same in each model code: not less than 30" nor more than 44" above the floor. While design may dictate where the push bar is located, consideration should be given in assigning a mounting height to either the lower or upper limits. The lower height is suggested for grade schools, while the upper height may be better suited for adult use, i.e. colleges. Consider where the trim is located on the opposite side of the door, as some manufacturers may have as much as 8"-10" differences between the centerline of the push bar and the centerline of pull trim. This height difference varies, depending on locking functions and type of exit device. Also consider applicable regulations for the physically disabled, as height requirements may vary. ADA (Americans with Disabilities Act) regulations permit 48" maximum height for accessible door hardware, while some state codes have a 42" limit. Some states also require the ends of lever trim to return to within 1/2" of the door face.

NFPA 101 34"-48"
NFPA 5000 same
IBC same
BOCA SBC, UBC 30"-44"

That's a very good point regarding wheelchair accessiblity! Achieving the best of two worlds is the real challenge. The current bar design does not favor those in the chair, unless the door opens automatically for them. You could almost throw the codes out the window and inspect using our practical and common senses.

I would still stand behind my initial answer of 44" but include an automatic push button between 30"-36" from the ground as a secondary opener for those in wheel chairs.
