Failure to take these code requirements into account could result in liability for blocked egress routes and fire door assemblies with labels which are null and void.
If electrified hardware is installed without the proper release devices, or magnetic cabinet locking system code locations where a product is not allowed by code, the cost to rectify the situation can be extensive. Understanding these requirements in advance can help to avoid these problems.
Informed application of access control hardware will protect life safety, ensure the effectiveness of fire doors, reduce liability and prevent costly replacement of non-compliant material. Following is a summary of the code requirements for four of the most prevalent access control devices found in a typical building. The summary is intended to provide magnetic cabinet locking system code with a overview of the key areas of the code.
Any product used as part of a fire door assembly must be listed for that use. This includes the access control lock or fire exit hardware, power transfer, door position switch or any other component mounted on the door or frame.
One of the requirements for a fire door is that it must be self-latching, so removing a mechanical lockset and replacing it with an electromagnetic lock would not meet the latching requirement. If an electric strike is installed on a fire door assembly, it must be fail-secure so that, upon power failure, the keeper is secure and the door is latched. The most common issue when installing electrified hardware on an existing fire-rated opening is the limitation on field preparation of magnetic cabinet locking system code doors and frames.
Round holes may be drilled in the field to accommodate operating components like cylinders, spindles and through-bolts with a maximum Magnetic Cabinet Locking System Zero hole size of 1-inch, except for cylinder holes which may be any diameter. Any field modifications beyond what is allowed by NFPA 80 may magnetic cabinet locking system code that the assembly be re-labeled by the listing agency, which can be very expensive.
A delayed egress lock is designed to delay the magnetic cabinet locking system code from unlocking for 15 seconds and, then, allow free egress. Immediate egress is required upon power failure or fire alarm.
A delayed egress lock cannot be installed if a building is not protected by an automatic sprinkler system or approved automatic smoke or heat detection system. An audible alarm and emergency magnetic cabinet locking system code are required in the vicinity of the door, and signage stating how the delayed egress lock functions must be posted on the door. The second timer must be initiated by a pound maximum force, and the delayed egress lock Magnetic Cabinet Locking System Site must be rearmed manually after the release cycle is complete.
It must also be able to be released remotely. The codes vary regarding requirements for delayed egress hardware. NFPA allows delayed egress locks in all low and ordinary hazard occupancies but, in some cases, there are conditions for their use. For example, on assembly occupancies, NFPA allows delayed egress locks on any doors other than the main entrance. Another difference between codes is the length of time allowed for actuation of the second timer.
The IBC requires the timer to start when force is applied for 1 second; while NFPA allows the force to be applied for up to 3 seconds.
The IBC also limits delayed egress devices to one delay before entering an exit for example, a protected stairwellwhile magnetic cabinet locking system code requirement varies by occupancy type per NFPA It is imperative to know which code is being enforced in the location in magnetic cabinet locking system code to apply the appropriate requirements. Electromagnetic locks are often used for retrofit access control applications because the installation is relatively easy compared to other electrified locks.
The main difference between the two sets of requirements is that the original section required electromagnetic locks to be released by magnetic cabinet locking system code of the following:.
The new sections allow the electromagnetic lock to be released by a door-mounted release device i. Loss of power to the switch is required to unlock the electromagnetic lock.
If door-mounted hardware is used to release the electromagnetic lock, the release devices are not required. In the edition of the IBC, electromagnetic locks may be used on doors with panic hardware as long as actuation of the panic hardware releases the electromagnetic lock. This is a change from the edition. When door hardware is installed in magnetic cabinet locking system code to control access from the stair into a tenant space, the requirements for stairwell re-entry must be considered.
The purpose of stairwell re-entry is to enable a building occupant to leave the stair if it becomes compromised during a fire and enter the tenant space to seek egress via another stair. Stairwell re-entry also magnetic cabinet locking system code firefighter access to the floors. Free egress from the tenant floors to the stairwell must be allowed at all times, except for specific exceptions detailed in the codes. Codes typically require stair doors to be equipped with fail-safe electrified locks or fail-safe electrified lever trim for fire exit panic hardware.
These products ensure that the doors can be unlocked automatically upon fire alarm or by a signal from the fire command center and that they magnetic cabinet locking system code latched as required for fire doors.
The magnetic cabinet locking system code of release — fire alarm or signal from fire command center — varies depending on which code is being used. A fail safe electric strike is not an option for stairwell re-entry, because electric strikes installed on fire doors must be fail-secure.
The edition of the IBC allows stairs serving four stories or less to have mechanical locks on the stair side. No remote or automatic release was required for these doors; however, the more recent editions of the IBC require fail-safe locks with remote release, even for stairs serving 4 stories or less. For stairs in high-rise buildings where stair doors are locked electrically, the IBC requires a telephone or two-way communication at every fifth floor, which is connected to a constantly attended station.
The exit discharge — typically at ground level, would allow free egress at all times. Signage is required at each level inside of the stairwell, directing building occupants to the unlocked floors.
Before installing access control hardware, ensure that your proposed products are acceptable for the applicable use group and that all code requirements are met. Doors with access control must not obstruct egress routes or negatively impact fire barriers. As a general rule of thumb, free egress is required at all times, not just upon fire alarm — although there are some exceptions, particularly in healthcare.
Your informed application of the installation and use of access control hardware will protect life safety, ensure the effectiveness of fire doors, reduce liability and prevent costly replacement of non-compliant material.

Delayed Egress A delayed egress lock is designed to delay the door from unlocking for 15 seconds and, then, allow free egress. Electromagnetic Locks Electromagnetic locks are often used for retrofit access control applications because the installation is relatively easy compared to other electrified locks. The main difference between the two sets of requirements is that the original section required electromagnetic magnetic cabinet locking system code to be released by any of the following: A sensor initiated by an approaching occupant; A marked emergency push button mounted beside the door, which unlocks magnetic cabinet locking system code door for 30 seconds independent of the access control system ; Actuation of the fire alarm; and Loss of magnetic cabinet locking system code to the lock.
Stairwell Re-entry When door hardware is installed in stairwells to control access from the stair into a tenant space, the requirements for stairwell re-entry must be considered. Plan Ahead Before installing access control hardware, ensure that your proposed products are acceptable for the applicable use group and that all code requirements are met. Final Thoughts Your informed application of the installation and use of access control hardware will protect life safety, ensure the effectiveness of fire doors, reduce liability and prevent costly replacement of non-compliant material.
