Synchronized Notification

Synchronize both Audible & Visual Notification

18.4.2.5* The standard evacuation signal shall be synchronized within a notification zone.

(Sounder bases must be synchronized with corridor horns)

14


Low Frequency Requirements

18.4.5.3

Waking Effectiveness:

The low frequency signal with a fundamental frequency of 520 Hz is most effective signal for awakening people who are hard of hearing.

Low frequency 520 Hz signal awoke 92% between 55 dBA and 75 dBA.

Low frequency signal is superior to bed and pillow shakers and strobe lights.


Sleeping Area Requirements – 18.4.5

18.4.5 Sleeping Area Requirements.

18.4.5.1* Where audible appliances are installed to provide signals for sleeping areas, they shall have a sound level of at least 15 dB above the average ambient sound level or 5 dB above the maximum sound level having a duration of at least 60 seconds or a sound level of at least 75 dBA, whichever is greater, measured at the pillow level in the area required to be served by the system using the A-weighted scale (dBA).

18.4.5.2 If any barrier, such as a door, curtain, or retractable partition, is located between the notification appliance and the pillow, the sound pressure level shall be measured with the barrier placed between the appliance and the pillow.

18.4.5.3* Effective January 1, 2014, where audible appliances are provided to produce signals for sleeping areas, they shall produce a low frequency alarm signal that complies with the following:

(1) The alarm signal shall be a square wave or provide equivalent awakening ability.

(2) The wave shall have a fundamental frequency of 520 Hz ± 10 percent.


NFPA72 – 2010 EditionCh 24 – Emergency Communications24.4.1.4 Tones. The tone preceding any message shall be permitted to be a part of the voice message or to be transmitted automatically from a separate tone generator.

24.4.1.4.1 In occupancies where sleeping accommodations are provided, the pre-alert tone shall include a low frequency component of 520 Hz square wave range to accommodate the need of the hearing impaired for fire voice messages and emergency communication messages.


NFPA72 – 2010 EditionCh 29 – Single and Multiple-Station

• 29.3.8 Notification appliances provided in sleeping rooms and guest rooms for those with hearing loss shall comply with 29.3.8.1 and 29.3.8.2, as applicable.

• 29.3.8.1 Mild to Severe Hearing Loss. Notification appliances provided for those with mild to severe hearing loss shall comply with the following:

(1) An audible notification appliance producing a low frequency alarm signal shall be installed in the following situations:(a)*Where required by governing laws, codes or standards for people with hearing loss(b) Where provided voluntarily for those with hearing loss(2)*The low frequency alarm signal output shall comply with the following:(a) The alarm signal shall be a square wave or provide equivalent awakening ability.(b)*The wave shall have a fundamental frequency of 520 Hz + / −10 percent.(c) The minimum sound level at the pillow shall be 75 dBA, or 15 dB above the average ambient sound level, or 5 dB above the maximum sound level having a duration of at least 60 seconds, whichever is greater.

SLC Zones - 2013 & 2016 Updated

Added 23.6.1, introducing the concept of signaling line circuit (SLC) zones and the requirements associated with not permitting a single fault on the SLC to cause the loss of devices in more than one zone.

(The intent of 23.6.1 applies to both short-circuit faults and open-circuit faults.)

23.6.1* SLC Zones.

A single fault on a pathway connected to the addressable devices shall not cause the loss of the devices in more than 50 addressable devices one zone.

23.6.1.1 each floor

23.6.1.2 multiple zones per floor, smoke zones, fire walls, relocation areas

24


SLC Zones – 2016 Edition

Depicts a Class B SLC with four zones.

Wiring of more zones would require one isolator for each additional zone.

The isolator can be integrated into the device or a separate component.

If a single short or open occurs beyond the isolators, only one zone will be affected.

25


SLC Zone – Class A

• Depicts a Class A SLC with four zones.

• Wiring of more zones would require one isolator for each additional

• zone.

• The isolator can be integrated into the device or a separate component.

• If a single short or open occurs, only one zone will be affected.

• If a single open occurs, no devices will be affected

26


SLC Zones – Hybrid Class A with Class B

• Depicts a hybrid Class A - SLC loop with Class B - SLC branches serving four zones that is designated as a Class B - SLC.

• Wiring of more zones would require one isolator for each additional zone.

• The isolator can be integrated into the device or a separate component.

• If a single short occurs, only one zone will be affected. If a single open occurs, it might affect only one zone.

27


SLC Zone – Class B Incorrect Method

• Depicts an incorrect Class B - SLC configuration with four zones.

• If a single short or open occurs, one or more zones could be affected depending on the location of the single short.
