Committee Statement:
The revision incorporates the changes to 7.2.1.5.10 in PIs-161, 428, 462, as revised, by moving the proposed reference to ANSI/BHMA A.156.41 to Annex A for guidance rather than mandating compliance, and 479.
Current A.7.2.1.5.10: The provision adds “locks” to Annex for consistency with proposed text revisions in PI 428 . Revising “electromagnetic” to “electrical” to not prescriptively suggest devices other than electromagnetic locks are prohibited.
Moving / deleting last sentence of Annex to 7.2.1.5.10.3 to become mandatory requirements consistent with ANSI A117.1, as proposed in PI 428.

7.10.2 * Directional Signs.
A. 7.10.2
Directional signage that has capability to change the displayed information based on real-time conditions presents a series of tradeoffs . The potential benefit of a changing message sign would be to deter occupants from a direction of travel that might be blocked or otherwise unavailable due to adverse conditions such as fire, structural collapse, or other unsafe conditions that may warrant avoidance.
However, the potential problems of such a “solution” include the reliability and likely partial level of the information available; the decision making ability of the individual (if human) or algorithm (if machine) responsible for changing the sign’s message; the capacity and condition of the remaining egress paths;
the training and habitual behavior of some building occupants who might not detect the change or might choose to ignore the sign’s information and thus create conflicting movement patterns; the increased probability of sign failure or malfunction due to its enhanced electronics; and the uncertainty for liability if the sign’s change of information leads to injuries or other adverse impacts that otherwise might have been avoided.
Directional signs for egress are used at all times of building occupancy. Only a very small percentage of building evacuations would likely benefit from this sign information enhancement. It is also likely that an unavailable egress path will make itself known through other means (such as smoke or other occupants moving away from it), although this might not provide as much advance notice to some occupants approaching from a distance.
The product standard for listing exit signs, UL 924 (referenced by 7.10.7. 1 ), does not currently permit this feature; it requires (clause 41.7c) that a directional indicator be “…secured in a manner that cannot readily be changed.” This requirement deters changes to the building evacuation plan after approval by the AHJ.
A system that can change based on changing conditions modifies the role of the AHJ by inserting a new intermediary responsible for providing occupant egress information.
7.10.2.1
A sign complying with 7.10.3, with a directional indicator showing the direction of travel, shall be placed in every location where the direction of travel to reach the nearest exit is not apparent.
7.10.2.2
Directional exit signs shall be provided within horizontal components of the egress path within exit enclosures as required by 7.10.1.2.2.

Committee Statement
Committee Statement:
Technological advances in sensors, controls, and artificial intelligence algorithms are being designed into emergency lighting systems to allow them to adjust to changing building circumstances. But neither the Codes nor the product standards have regulations for evaluating the actual efficacy and reliability of these “solutions”. The situation is somewhat analogous to the use of GPS wayfinding systems for changing driving routes due to traffic congestion. But in this circumstance, the data set used for making decisions must be customized to the individual building (where are the sensors to be located and what conditions do they detect?) and the consequences for errors may be more severe than arriving late to an appointment. Some systems may involve humans in a central control area monitoring video cameras and making decisions, while other systems may be fully automated and utilize artificial intelligence algorithms to calculate optimized evacuation strategies. Both approaches, and any combination, has both potential benefits and pitfalls. This proposal for an Annex note is to stimulate discussion and the development of regulations that respond to this new deployment of advanced technology.

All locks, latches, and all other fastening devices on a door leaf shall be provided with a releasing device that has an obvious method of operation and that is readily operated under all lighting conditions.
7.2.1.5.10.1 [7.2.1.5.3.1]
The releasing mechanism for any latch locks and latches shall be located as follows:
(1) Not less than 34 in. (865 mm) above the finished floor for other than existing installations (2) Not more than 48 in. (1220 mm) above the finished floor
7.2.1.5.10.2 * [7.2.1.5.3.2]

A. 7.2.1.5.10. 2
An example of a releasing motion in a single linear direction, as described in ANSI/BHMA A156.41, Standard for Door Hardware Single Motion for Egress, is pushing on a panic bar to release the locking/latching hardware to allow a door to be opened. An example of a releasing motion in a single rotational direction is turning a lever-operated handle of a door lockset in either a clockwise direction or a counterclockwise direction, but not both directions, to unlock/unlatch the door.
7.2.1.5.10. 3
*
[7.2.1.5.3.3]
The releasing mechanism for new installations shall be capable of being operated with one hand and shall not require tight grasping, tight pinching, or twisting of the wrist to operate.
7.2.1.5.10.3 * [7.2.1.5.3.4]
Egress door assemblies from individual living units and guest rooms of residential occupancies shall be permitted to be provided with devices, including automatic latching devices, that require not more than one additional releasing operation motion , provided that such device is operable from the inside without the use of a key or tool and is mounted at a height not exceeding 48 in. (1220 mm) above the finished floor.
7.2.1.5.10.4 [7.2.1.5.3.5]
Existing security devices permitted by 7.2.1.5.10.3 shall be permitted to have two additional releasing operations motions .
7.2.1.5.10.5 [7.2.1.5.3.6]
Existing security devices permitted by 7.2.1.5.10.3, other than automatic latching devices, shall be located not more than 60 in. (1525 mm) above the finished floor.
7.2.1.5.10.6 [7.2.1.5.3.7]
Two releasing operations motions shall be permitted for existing hardware on a door leaf serving an area having an occupant load not exceeding three, provided that releasing does not require simultaneous operations.
7.2.1.5.10.7
Where permitted by Chapters 11 through 43 , two releasing operations shall be permitted for doors secured against unwanted entry.
