At that basic level, specifying hardware to meet applicable code coverage is apt to be fairly simple. Once designers and specifiers begin to include more sophisticated and secure electronic access control systems, however, the ante goes up.<\/p>\n<p>This approach moves the installation closer to full security integration\u2014potentially incorporating such diverse elements as access recording, remote access control and alarming, video monitoring, and card or proximity reading. This is in addition to numerous higher-tech architectural hardware elements that may be incorporated, including magnetic locks and tamperproof or hidden hardware elements.<\/p>\n<p>At these higher degrees of complexity, the specifier\u2019s job becomes correspondingly more complicated. In particular, specification writers can benefit from familiarity with code materials governing three categories of the architectural door hardware\/integrated security interface:<\/p>\n<ul>\n<li>access-controlled egress doors;<\/li>\n<li>electrically controlled egress doors; and<\/li>\n<li>delayed egress doors.<\/li>\n<\/ul>\n<p>Within <em>MasterFormat<\/em> Division 08 70 00\u2013Door Hardware specifications, it is a common practice to cite multiple model codes to adequately define all life safety and security compliance requirements.

Understanding how to balance security with egress is critical.<\/span><\/figcaption><\/figure>\n<p>While the code bodies have worked hard to reconcile and harmonize, subtle differences exist among various definitions and descriptions. The access control and door hardware specifier, acting as the overall life safety and security consultant, must be aware of these subtle variations when designing an electronic access control security plan.<\/p>\n<p>For electronically controlled door assemblies, many considerations must be taken into account to achieve the overall life safety and corresponding security desired for the building. The types of controls can include controlled ingress and egress, including when, why, and by whom. Properly specified, installed, and maintained, the system complies with all life safety codes while providing a comprehensive security solution for the building.<\/p>\n<p>Electronic access control hardware is designed to be employed in conjunction with widely used architectural door hardware such as traditional door locks, exit devices, and door closers. For example, to monitor an entry door and determine if it is locked, a latch-bolt-monitoring device can be integrated into the door frame using standard locks with built-in switch, or an electric strike or door position switch or sensor.<\/p>\n<p>The idea behind monitoring and confirming true latch-bolt latching and locking is basic. Even when part of the most sophisticated plan that deploys the latest in surveillance technology, a door that is not properly latched and locked presents a major security breach. Use of a latch monitor switch, door position switch, or door position sensor offers a simple but effective solution for remotely monitoring the door\u2019s status, detecting whether it is actually latched and locked.<\/p>\n<p><strong>Access-controlled egress doors<\/strong><br \/>\nThe subject of access-controlled egress doors is addressed in substantial detail in both the <em>International Building Code<\/em> (<em>IBC<\/em>) and National Fire Protection Association (NFPA) 101, <em>Life Safety Code<\/em>. The relevant material in the latter is in Chapter 7, Section 7.2, Paragraph 7.2.1.6.2 (\u201cAccess-controlled Egress Door Assemblies\u201d), which governs multiple aspects of door hardware specifications. It requires all the following elements be included:<\/p>\n<ul>\n<li>sensor on the egress side that is set up to unlock the door leaf in the direction of egress when an occupant approaches;<\/li>\n<li>door leaves that automatically unlock in the direction of egress when power is lost to the sensor or the access control system;<\/li>\n<li>locks that can be unlocked using a manual release device (NFPA 101 provides specifics concerning the nature of this device, mandating its location, signage support, and its ability to directly interrupt power to the lock, independent of locking system electronics);<\/li>\n<li>automatic unlocking of the door leaves in the direction of egress when the building\u2019s fire protective signaling system, fire detection system, or sprinkler system is activated (locks must remain unlocked until the signaling system is reset); and<\/li>\n<li>emergency lighting on the egress side of such doors, except in the case of existing access-controlled egress doors.<\/li>\n<\/ul>\n<p class=\" wp-image-3754\">Subsection 5 of Chapter 7, Section 7.2, Paragraph 7.2.1.6.2 asserts the activation of manual fire alarm boxes that activate the building fire-protective system shall not be required to unlock the door leaves. Subsequent language in the code explains the intentions of the paragraph, including the mutually supporting characteristics it entails.<\/p>\n<p>In contrast, <em>IBC<\/em> Section 1008.1.9.8 is briefer, and is not immediately followed by in-depth supporting language. Nevertheless, it covers much of the same ground, addressing the ways in which the locking system must be unlocked when the building\u2019s fire detection, alarm, and sprinkler systems are activated. Subsection 6 states directly that entrance doors in buildings with four specified groups of occupants \u201cshall not be secured from the egress side during periods that the building is open to the general public.\u201d The defined occupancy groups are further discussed later in this article.<\/p>\n<figure id=\"attachment_3754\" aria-describedby=\"caption-attachment-3754\" style=\"width: 232px\" class=\"wp-caption alignright\"><a href=\"http:\/\/www.constructionspecifier.com\/wp-content\/uploads\/2014\/05\/WilsOffice_0013.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-3754\" src=\"http:\/\/www.constructionspecifier.com\/wp-content\/uploads\/2014\/05\/WilsOffice_0013-666x1000.jpg\" alt=\"In healthcare applications, the access control and door hardware specifi er often acts as the overall life safety and security consultant.

Five conditions must be met in order to integrate electronic access control hardware:<\/p>\n<ul>\n<li>the lock\u2019s occupant release is affixed to the door leaf;<\/li>\n<li>hardware must have an obvious method of operation readily operated in the direction of egress;<\/li>\n<li>hardware is capable of being operated with one hand in the direction of egress;<\/li>\n<li>operation interrupts the power supply directly to the lock, unlocking the door assembly in the direction of egress; and<\/li>\n<li>loss of power to the listed releasing hardware automatically unlocks the door in the direction of egress.<\/li>\n<\/ul>\n<p>This last provision refers to a function designed as \u2018fail safe,\u2019 meaning that when power is cut off from the device, the locking device unlocks, enabling occupants to exit the building unimpeded and first responders to gain free access to the building. Additionally, this section also requires the use of separate power to control the electric door hardware shall be listed in accordance with Underwriters Laboratories (UL) 294, <em>Access Control System Units<\/em>.<\/p>\n<p><a name=\"note2\"><\/a>In comparison, <em>IBC<\/em> Section 1008.1.9.9 (\u201cElectromechanically Locked Egress Doors\u201d) offers additional guidelines defining doors in the means of egress, listing specific occupancy groups.<a href=\"#note1\"><sup>1<\/sup><\/a> Among these groups, A, B, E, M, R-1, or R-2 (and doors to tenant spaces in these categories) are permitted to have electromagnetically operated locks if equipped with listed hardware that incorporates a built-in switch and meets the requirements below:<\/p>\n<ul>\n<li>listed hardware affixed to the door leaf has an obvious method of operation readily operated under all lighting conditions;<\/li>\n<li>listed hardware is capable of being operated with one hand;<\/li>\n<li>operation of listed hardware directly interrupts the power to the electromagnetic lock and unlocks the door immediately;<\/li>\n<li>loss of power to the listed hardware automatically unlocks the door; and<\/li>\n<li>where panic or fire exit hardware is required by Section 1008.1.10, operation of the listed panic or fire exit hardware also releases the electromagnetic lock.<\/li>\n<\/ul>\n<p>In other words, despite some differences, the applicable code sections are quite similar in language and in effect. Both NFPA and <em>IBC<\/em> invoke the term \u201clisted\u201d to mean UL-listed to the appropriate standard. In the case of electric strikes and shear locks, these devices would be listed to UL 1034, <em>Burglar Resistant Electrically Operated Door-Locking Systems<\/em>, and UL 10C, <em>Positive Pressure Fire Tests of Door Assemblies<\/em>, for fire ratings (when used with appropriately listed doors).<\/p>\n<p><strong>Delayed egress<\/strong><br \/>\nBoth <em>IBC<\/em> and NFPA 101 allow for one exception to standard means of egress\u2014\u2018delayed egress,\u2019 which prevents a door from being opened for either 15 or 30 seconds. Building occupants may attempt to open egress doors in emergency or non-emergency situations. The intention with delayed egress is to deter the residents of assisted living facilities and some healthcare facilities from exiting the premises, but without putting their lives at risk.<\/p>\n<p class=\" wp-image-3750\">A wandering Alzheimer patient, for instance, cannot normally be permitted simply to push an exit device touch bar and freely leave. In certain emergencies, however, that patient\u2019s life may depend on being able to open the door after a delay. <em>IBC<\/em> and NFPA 101 allow for the 15- or 30-second delay before the locking device unlocks. An alarm will sound and, in non-emergency situations, the alerted staff can assist the patient who is attempting to open the door.<\/p>\n<p>Again, the codes address the issue in notably different ways. NFPA 101 Chapter 7, Section 7.2, Paragraph 7.2.1.6.1 (\u201cDelayed Egress Locking Systems\u201d) permits installation of approved, listed delayed-egress locking systems on door assemblies serving low and ordinary hazard contents. However, this is only true in buildings protected throughout by an approved, supervised automatic fire detection system in accordance with NFPA 101 Section 9.7, and where permitted in specified chapters of the code. Further, all the following criteria must be met:<\/p>\n<p><span style=\"font-size: 12pt; font-family: times new roman,times;\">(1) The door leaves shall unlock in the direction of egress upon actuation of one of the following:<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(a) Approved, supervised automatic sprinkler system in accordance with Section 9.7<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(b) Not more than one heat detector of an approved, supervised automatic fire detection system in accordance with Section 9.6<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(c) Not more than two smoke detectors of an approved, supervised automatic fire detection system in accordance with Section 9.6<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(2) The door leaves shall unlock in the direction of egress upon loss of power controlling the lock or locking mechanism<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(3) An irreversible process shall release the 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 7.2.1.5.1.10 under all of the following conditions:<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(a) The force shall not be required to exceed 15 lbf (67N).<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(b) The force shall not be required to be continuously applied for more than three seconds.<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(c) The initiation of the release process shall activate an audible signal in the vicinity of the door opening.<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(d) Once the lock has been released by the application of force to the releasing device, relocking shall be by manual means only.<\/span><br \/>\n<span style=\"font-size: 12pt; font-family: times new roman,times;\">(4) A readily visible, durable sign in letters not less than 1 in.
