j. Visible notification is not required in single person offices, unless the office is assigned to a person with a hearing impairment that would require a visible notification appliance.

k. Visible notification is not required in bathrooms serving single person offices, unless the office is assigned to a person with a hearing impairment that would require a visible notification appliance.

l. Visible notification appliances must be provided with a clear lens marked "Alert". The use of "Fire" is not permitted.

Mass Notification System (MNS).

Refer to UFC 4-021-01.

Voice Message.

For systems using voice evacuation or combined with the mass notification system, the default fire alarm voice evacuation message\2\ should/2/ be a female voice and state the following:

(Temporal 3 Alert Tone) "May I have your attention please. May I have your attention please. A fire emergency has been reported in the building. Please leave the building by the nearest exit or exit stairway. Do not use the elevators".

<provide a 2 second pause> "May I have your attention please..." (repeat the message).

Installations with formally established and approved/published in accordance with the Service/Agency policy standard signals and messages are permitted to utilize those standard signals and messages. \2\/2/The general format must be a specific alert signal tone(s) followed by a voice announcement(s) and then repeats the cycle for a specific number of cycles or continuously as appropriate for the message.

Note 1: For single-story Facilities, delete "or exit stairway. Do not use the elevators" from the voice message.

\2\Note 2: See “Appendix E” for guidance on other messages./2/

3-19.4 Fan Coil Units and Air Conditioners.

All new buildings required to comply with these standards must have a system that allows fan coil units to be shut off in an emergency. Fan coil units and air conditioners do not require low leakage dampers.

For existing inhabited buildings required to comply with these standards, emergency shutoffs for fan coil unit heaters and air conditioners are recommended.

3-20 STANDARD 19. EQUIPMENT BRACING.

For new construction and existing buildings required to comply with these standards mount all overhead utilities and other fixtures weighing 31 pounds (14 kilograms) or more (excluding distributed systems such as piping networks that collectively exceed that weight) using either rigid or flexible systems to minimize the likelihood that they will fall and injure building occupants. Design all equipment mountings to resist forces of

0.5 times the equipment weight in any horizontal direction and 1.5 times the equipment weight in the downward direction. This standard does not preclude the need to design equipment mountings for forces required by other criteria such as seismic standards.

3-21 STANDARD 20. UNDER BUILDING ACCESS.

To limit opportunities for aggressors placing explosives underneath buildings, ensure that access to crawl spaces, utility tunnels, and other means of under building access is controlled in all buildings required to comply with these standards.

3-22 STANDARD 21. MASS NOTIFICATION.

All buildings required to comply with these standards must have a timely means to notify occupants of threats and instruct them what to do in response to those threats. To achieve that goal, provide the following:

Buildings must have a capability to provide real-time information to building occupants or personnel in the immediate vicinity of the building during emergency situations. The information relayed must be specific enough to determine the appropriate response actions. The information must be capable of being originated both locally at the building and from a remote location. Design building MNS in accordance with UFC 4-021-01.

4-3.2 ACU

4-3.2.1 Functions. The ACU is used to monitor and control the notification appliance network. At the ACU, personnel in the building can initiate delivery of pre-recorded voice messages, provide live voice messages and instructions, and initiate visual strobe and alphanumeric message notification appliances. Actions taken at the ACU take precedence over actions taken at any other location, including the LOC, or inputs from the wide area MNS on the DOD installation.

4-3.2.2 Combined System. For new construction, the ACU shall be integrated with the building fire alarm control panel (FACP) to form one combined system that performs both functions. The building PA system for smaller buildings may be integrated with the combined system so that all three functions—mass notification, fire alarm, and PA—are provided by one building system. In large buildings, however, combining the PA system will typically require the design of very complex speaker switching matrices and is not recommended. Combined systems shall meet the requirements of NFPA 72.

Note: A combined system may include an ACU and FACP supplied from different manufacturers or placed in separate equipment enclosures; however, the ACU and FACP must be integrated in their controls and performance to meet the requirements of NFPA 72 and this UFC.

Note: The Army and Air Force permit the MNS and fire alarm system to be installed as separate systems if mandated by the DOD installation. The Marine Corps normally requires the MNS and fire alarm system to be installed as separate systems unless specifically permitted by the AHJ. See Chapter 5 for technical criteria for this design approach.

4-3.3 LOC. A LOC is a unit designed to allow emergency response forces and building occupants to operate the individual building MNS, including initiating delivery of pre-recorded voice messages, providing live voice messages and instructions, initiating visual strobe and alphanumeric message notification appliances, overriding external voice announcements, and terminating mass notification functions. A LOC is usually contained in a small, wall-mounted enclosure. Not all functions that could be performed at the ACU are necessarily available at a LOC.

4-3.4 Notification Appliance Network. A notification appliance network consists of a set of audio speakers, strobes, and text signs (when required) that are located to alert occupants and provide intelligible voice and visual instructions.

4-3.4.1 Audio Appliance Network. Speakers are provided at all locations in the building and also around the building at entrances/exits and other outdoor areas (such as courtyards) commonly used by the building occupants. Important design considerations for the audio speakers include intelligibility and audio intensity.

Note: Outside notification more than 5 m (16 ft) from the building should be provided by the wide area MNS.

1123921123C Highlight

Change 1, January 2010

Install a LOC at those facility entrances/exits that will be used when building access is limited because of elevated terrorism threat levels.

Note: This LOC is intended to enable immediate notification of building occupants when unauthorized building access is threatened or has occurred at this location.

Army and Air Force: Provide a LOC so that occupants do not need to travel more than 61 m (200 ft) horizontally or to travel to other floors to access a

LOC.

Army and Air Force: Make a LOC available for use by visitors in those facilities open to unescorted visitors or to the public.

Navy: Provide no more than one LOC (if necessary) in addition to the ACU.

Locate the LOC as directed by the responsible fire protection engineer.

Marine Corps: Provide no more than one LOC (if necessary) in addition to the ACU. Locate the LOC as directed by the AHJ.

4-5.2 Design Features. The LOC shall:

Have a remote microphone station that emulates operation of the MNS from the ACU.

Have an easy method (such as individual manual activation push buttons) of activating the MNS pre-recorded messages. Signage shall be provided to allow rapid recognition of the means of initiating the pre-recorded messages.

Activation of MNS pre-recorded messages is not required for Marine Corps

LOC.

Provide a single switch or operating mechanism capable of shutting down all HVAC equipment in the facility in accordance with the requirements of UFC 4- 010-01. If permitted by the DOD installation, this shutdown capability may be provided at only one LOC when multiple LOCs are installed, or be deleted from all LOCs if the capability is otherwise provided at a location readily accessible to building occupants.

Be protected in a small, wall-mounted enclosure.

Have supplemental heating and ventilation for those enclosures located outdoors or in areas where the LOC will be exposed to temperatures or humidity outside of the manufacturer’s design limits.

Be protected from tampering by use of a break-glass, thumb-lock, tamper wire, tamper alarm, or equivalent protection. This is not required in those

Change 1, January 2010

5-7.2.1 Navy-Specific Requirements

Provide clear strobes marked with the word “ALERT” for shared use by the facility’s MNS and FACP.

Provide LED text signs. Text signs are required over the door to each egress stairwell and over (or adjacent to) the substantial means of egress from the level of discharge. Exterior exit doors from a single room (e.g., mechanical or electrical rooms) do not require a text sign. (See Chapter 7 for operational requirements and information on message content.)

5-7.2.2 Marine Corps-Specific Requirements

Contact the AHJ for guidance on visual notification appliances.

5-7.2.3 Army- and Air Force-Specific Requirements

Provide amber-colored strobes marked with the word “ALERT” to alert the hearing impaired. Provide these strobes in addition to existing clear strobes provided for the building fire alarm system.

Amber strobes activated in conjunction with the delivery of a pre-recorded voice message shall operate continuously until message termination. Amber strobes activated in conjunction with the delivery of a live voice message shall operate during the message and for not less than 15 seconds after the message ends.

Clear/white strobes activated by the fire alarm system shall not operate during those periods when the amber strobes are in operation, but otherwise shall operate continuously until the fire alarm system is reset.

5-8 INTERFACES WITH WIDE AREA MNS. The individual building MNS shall be capable of interfacing with an existing wide area MNS. If a wide area MNS is not presently provided on the DOD installation, the individual building MNS shall be designed to allow future interface with a wide area MNS procured from another manufacturer. The electrical requirements, computer codes, or other protocols that are needed to interface the systems shall be provided to the DOD installation. At a minimum, the wide area MNS shall be able to provide and the individual building MNS shall be able to receive an audio line-level input. The individual building MNS shall not be activated or controlled by a giant voice system unless the giant voice system also meets the design and performance requirements of a wide area MNS.
