What are exit devices?

Exit devices are used to secure openings while at the same time providing immediate egress in the case of emergency. An exit device is a piece of hardware mounted on the push side of a door. It is designed to release a latching mechanism in the event of panic. Exit devices are intended to operate without prior knowledge or training when pressure is applied to horizontal bar or push pad mounted to the door. Because of their direct effect upon life safety, exit devices are one of the most important hardware items in a building.

How many designs of exit device are available?

Exit devices are available in two design styles: The contemporary touch bar type The touch bar type usually is a one-piece assembly consisting of a rectangular body extending from the lock stile to the hinge stile. A portion of the body protrudes away from the unit, acting as a touch bar (touch pad/contact from the unit, acting as a touch bar (touch pad/contact surface). Pressure against this touch bar will retract the latch or vertical rods at the end of the assembly. The traditional cross bar type The crossbar type has two cases, a lock stile case and a hinge stile case. A conventional round cross bar connects horizontally across the door to both of them. Pressing the crossbar toward the door retracts the latch.

Panic Hardware & Fire Exit Hardware

What is the difference between Fire Exit Hardware and Panic Hardware?

Panic Hardware and Fire Exit Hardware are two different types of exit devices, and the proper selection is determined by code requirements.

Panic Hardware: Panic Hardware is an exit device which is tested for use on a door that is required to have panic hardware, but cannot be used on a fire door. Panic hardware typically has the dogging feature, which allows the latches to be held retracted to create a push/pull function.

Fire Exit Hardware: Fire Exit Hardware is an exit device which is tested for both panic and fire conditions and is required to be used on fire doors where panic hardware is required by code or desired for durability.

Fire Exit Hardware shall be listed in accordance with UL 10C and UL 305; Fire Exit Hardware intended to keep a fire door latched to prevent the spread of smoke and fire, thus maintaining the integrity of the fire assembly.

Since fire doors require positive-latching,fire exit hardware does not incorporate mechanical dogging.If a push/pull function is desired for a fire door, electric latch retraction hardware may be installed, as long as the latch projects automatically upon fire alarm.

The International Building Code (IBC) and NFPA 101 – The Life Safety Code contain similar requirements for locations where panic hardware is installed:

Panic hardware shall be listed in accordance with UL 305;
Fire Exit Hardware shall be listed in accordance with UL 10C and UL 305;
The actuating portion of the releasing device shall extend at least one-half of the door leaf width;
The maximum unlatching force shall not exceed 15 pounds (67 N).
If balanced doors are used and panic hardware is required, the panic hardware shall be the push-pad type and the pad shall not extend more than one-half the width of the door measured from the latch side.

Tests & Label

To be listed as acceptable for these uses, a sample device must pass a series of tests. The two most important are that the device operates for a specific number of cycles, and that the opening pressure(force required to release the device) must not exceed certain levels. Both Panic hardware and Fire Exit hardware must pass this portion of the test. The maximum force to unlatch the device is specified in most model building codes.

Before a device can listed as Fire Exit hardware it must pass further testing. Complete assemblies of doors, frames and hardware are put together in a wall to form an assembly on which a laboratory fire test will be performed. Depending on the length of the fire test, the devices will be listed as 3 hour(A Label); 1½ hour(B Label) or possibly a shorter time.

Note: Doors which are constructed to accept fire exit hardware will bear a label noting this fact. The label of the device also will indicate it is a Fire Exit Hardware device.

Construction:

While Panic hardware and fire exit hardware can appear to be aesthetically the same, there are significant internal differences in their construction.

The latching assemblies on fire exit hardware have to be constructed in such a manner as to ensure the doors will be held in the closed and latched position during a fire.

Dogging:

Another difference between panic hardware and fire exit hardware is that panic hardware is permitted to have a feature called dogging. The dogging feature holds the latchbolt（s）in the retracted position so that the doors may be used as push/pull. Dogging is accomplished either by a hex key or cylinder installed on the body of touch bar devices, or by a hex key in the hinge and lock cases of crossbar devices.

Dogging is prohibited on fire-rated devices because it prevents the latch-bolt from keeping the door in the latched position.

Q D&D panic bar suitable for what size of doors?

A Suitable for doors width from 650mm to 1000mm, door thickness from 44.5mm to 50mm, standard door height is 2100mm (door higher than standard, please contact D&D).
Q What material is the panic bar made of?

A It is available in stainless steel 304 and painted steel.
Q What finishes are available for panic bars?

A Our panic bars are available in a variety of finishes, such as satin, polish, black, gold, powder coating, steel painted etc.

Q What are the factors that influence the choice of exit device?

A
The following lists a few of those factors.

1. Door Design

2. Door Size

3. Door Glazing

4. Building Code and Owner Requirements

5. Overlapping Astragals
Q How do we know when we shall use fire exit hardware?

A
The requirement for using “exit device” or fire exit hardware usually is based on the occupancy classification of the building or area and the occupant load (quantity of persons using the facility).

The National Fire Protection Association (NFPA) publishes the Life Safety Code, which designates when exit devices are required to be used in a building or space.

• Exit devices are required to be used on openings serving an occupant load of 100 people or more, and high hazard areas with occupant loads of 5 or more.

• NFPA 101 requires fire exit hardware to be installed on fire-rated openings in a means of egress.
Q When an exit device is not functioning properly, what problem could it be causing that?

A
When an exit device is not functioning properly, the problem usually can be traced to one of the following factors:

• Poor fitting or alignment of door and frame

• Wrong lock or case

• Door prepared incorrectly

• Frame and/or door reinforcement incorrect

• Improper cylinder or installation

• Not mounted level

• Latch case not aligned

• Vertical rods not aligned

• Fasteners of wrong length

• Fasteners too loose or tight

• Operating trim not installed properly or binding
