2 9/20/2016 2:27 PM Second Revision No NFPA [ Section No ] Two releasing operations shall be permitted for educational occupancy classroom doors secured against unwanted entry in accordance with the provisions of Chapter 15. Submitter Full Name: SAF-MEA Submittal Date: Mon Jun 20 10:04:56 EDT 2016 It is the position of the TC on Means of Egress that increasing the number of latch/lock releasing operations is dangerous and could create a hazard to occupants. Technology exists that will meet the current code requirement for not more than one latch/lock releasing operation. The need for multiple operations is contrary to decades of experience resulting in fatalities in schools and other buildings. Single-action egress is an important aspect of life safety for all emergencies. Public Comment No. 42-NFPA [New Section after ]

(3)* An irreversible process shall release the electrical lock in the direction of egress within 15 seconds, or 30 seconds where approved by the authority having jurisdiction, upon application of a force to the release device required in under all of the following conditions: (a) The force shall not be required to exceed 15 lbf (67 N). (b) The force shall not be required to be continuously applied for more than 3 seconds. (c) The initiation of the release process shall activate an audible signal in the vicinity of the door opening. (d) Once the electrical lock has been released by the application of force to the releasing device, rearming the delay electronics shall be by manual means only. (4)* A readily visible, durable sign that conforms to the visual characters requirements of ICC/ANSI A117.1, Accessible and Usable Buildings and Facilities, shall be located on the door leaf adjacent to the release device in the direction of egress, and shall read as follows: (a) (b) PUSH UNTIL ALARM SOUNDS, DOOR CAN BE OPENED IN 15 SECONDS, for doors that swing in the direction of egress travel PULL UNTIL ALARM SOUNDS, DOOR CAN BE OPENED IN 15 SECONDS, for doors that swing against the direction of egress travel (5) The egress side of doors equipped with delayed-egress electrically electrical locking system shall be provided with emergency lighting in accordance with Section 7.9. (6) Hardware for new installations shall be listed in accordance with ANSI/UL 294, Standard for Access Control System Units The provisions of for sensor-release of electrical locking systems shall not apply to door assemblies with delayed-egress electrically electrical locking systems.

Submitter Full Name: SAF-MEA Submittal Date: Mon Jun 20 11:23:14 EDT 2016 The committee believes that verifying the presence of emergency lighting is appropriate, but functional testing of emergency lighting is covered in Section 7.9 and therefore does not need to be part of the door inspection procedures. The requirement for verifying the presence of emergency lighting is consistent with the other provisions in The revision also responds to CC Note 7, which replaces 'electrically' with 'electrical'. Public Comment No. 61-NFPA [Section No ]

7 3 9/20/2016 2:27 PM Second Revision No NFPA [ Section No. A ] A None of the special locking arrangements addressed in are intended to allow credentialed egress, request to exit, or similar provisions, where an occupant cannot leave the building without swiping a card through a reader. Where such an arrangement is desired to keep track of occupants, the swiping of cards needs to be procedural but not necessary for releasing the door lock or latch. Free egress needs to be available at all times. Another option to free egress is the use of a delayed-egress electrically electrical locking system. Submitter Full Name: SAF-MEA Submittal Date: Tue Jun 21 15:40:13 EDT 2016 : The revision responds to CC Note 7.

8 9/20/2016 2:53 PM Second Revision No NFPA [ Section No ] * Classroom Door Locking to Prevent Unwanted Entry. Classroom doors shall be permitted to be locked to prevent unwanted entry provided that the locking means is approved and all of the following conditions are met: The locking means is approved. (1) The locking means can shall be capable of being engaged without opening the door. (2) The unlocking and unlatching from the classroom side of the door can be accomplished without the use of a key or tool, tool, or special knowledge or effort. (3) The unlocking and unlatching requires releasing mechanism shall open the door leaf with not more than one releasing operation. (4) The releasing mechanism for unlocking and unlatching means are mounted shall be located at a height not less than 34 in. (865 mm) and not exceeding 48 in. (1220 mm) above the finished floor. (5) Locks, if remotely engaged, can shall be unlocked unlockable from the classroom side of the door without the use of a key, tool, or special knowledge or effort. (6) The door is capable of being unlocked and opened from outside the room by staff with the necessary key or other credential. (7) The locking means does shall not modify the door closer, panic hardware, or fire exit hardware. (8) Modifications to fire door assemblies, including door hardware, shall be in accordance with NFPA 80. (9) The emergency action plan, required by , addresses shall address the use of the locking and unlocking means from within and outside the room.

During the First Draft, the section was inadvertantly added with no charging statement. A statement has been added to the front of the Section to clarify that classroom doors are permitted to be locked to prevent unwanted entry only if the locking means is approved and all of the criteria in the list are met. The committee used some of the changes as proposed in Public Comment No.183 as the basis for edits to the section. Numbered items were updated with the word "shall" for editorial correction. Text was added to clarify that the unlocking and unlatching operation in the classroom cannot require the use of key, tool, special knowledge or effort which is consistent with other locking and latching provisions in Chapter 7. A minimum height for the location of the releasing mechanism, consistent with Chapter 7, was added to ensure that the mechanism was not located on the floor or low on the door and the text was updated to clarify that it is the releasing mechanism that must be located within the 34-48" range. Item 7 has been updated to delete 'by staff' from the First Revision as it was too specific. It may not just be staff opening the door, it could be first responders for example. The Workshop on School Safety, Codes and Security Final Report documented the need to lock classroom doors against unwanted entry and accepted the need that a second locking means may be needed for existing buildings. The multiple provisions proposed as part of / address the concerns for accomplishing door locking in a safe manner.

12 9/20/2016 2:53 PM The proposed language supports a safe installation and necessary guidance for situations that are already occurring in existing buildings. The language is written so that it is done to protect occupants but also to ensure the door is operable for safe and quick egress during emergencies. There are currently close to 100,000 existing public school buildings across the country. Without this guidance, non-compliant, and dangerous, installations will continue to occur. Other protection measures are required and relied upon by the Code as part of a total life safety approach. The intent of Chapter 15 is to provide those other measures necessary to ensure that total protection approach. For example, it is critical to ensure the door can be unlocked and opened from outside the room so as to not impede the ability for authorized responders to enter the classroom. The language permits not more than two releasing operations, two releasing operations are not mandatory. It is ultimately up to the local AHJ to approve the locking arrangement. Approval of locking devices may depend on individual scenarios such as classroom use, occupant load, and staffing. The committee supports this as a package of requirements that, together, provide the necessary guidance needed for classroom door locking in existing educational occupancies. The recognizes that hardware does exists, and could be used, that allows two locking mechanisms/devices with one releasing action, such as residential hotel locks.
