2.2.1 Expected Equipment Lifecycle

Notification equipment cannot last forever. Even though the Series SPB Audio Booster is
expected to last up to ten years, any of its parts or components could fail before then.

2.2.2 Periodic Testing

1. Cooper Wheelock recommends testing of the entire protective signaling system,

including the Series SPB Audio Booster panel, all notification equipment, as well as all
messages and their output channel, and priority assignment, at least twice each year, or
more often as required by local, state and federal codes, regulations and laws, by
qualified personnel.

2. If the notification equipment is not working properly, immediately contact the

installer and have all/any problems corrected immediately.

3. Replace any malfunctioning components immediately; do not attempt to repair

malfunctioning components. Return malfunctioning components for factory repair or

replacement. In the event you cannot contact the installer, contact the manufacturer.

WARNING: For proper operation in life safety applications,
perform the following: (a) Connect the Series SPB Audio Booster
panel to a listed compatible and properly operating voice evacuation
panel such as the Cooper Wheelock, Inc. SP40S panel, which controls
its activation. (b) Ensure that all equipment is properly
interconnected and operating. (c) Make sure the installer checks the
compatibility of all equipment prior to installation; otherwise, the
Series SPB Audio Booster panel and/or the voice evacuation panel
may be damaged and/or fail to operate in an emergency situation.

WARNING: Certain hardware functions on the Series SPB
Audio Booster panel are not supervised. If any such hardware
functions fail, the Series SPB Audio Booster panel may not provide
the intended warning and/or not indicate a trouble condition.

Series SPB Audio Boosters Manual, Revision A
2-2

Chapter 2: Safety Precautions

2.3 Compliance with Applicable Codes,
Regulations, Laws, Standards, and Guidelines

Comply with all of the latest applicable codes, regulations, laws, standards, and guidelines.

WARNING: Ensure that for emergency, life safety applications
using the Series SPB Audio Booster, installation, testing and
maintenance is always performed by qualified personnel in
accordance with all the latest National Fire Protection Association
(NFPA), Underwriter’s Laboratory (UL), National Electric Code
(NEC), Occupational Safety and Health Administration (OSHA),
state, county, local, province, district, federal, and other applicable
building and fire standards, guidelines, regulations, laws, and codes
including, but not limited to, all appendices and amendments and
requirements of the Local Authority Having Jurisdiction (AHJ).

It is recommended that the local Authority Having Jurisdiction (AHJ) inspect and approve the
proposed placement of all the notification appliances.

2.4 Property Insurance Recommendation

The Voice Evacuation System containing the SPB Series Audio Booster panel is not a substitute
for insurance. Make sure that you have adequate levels of life and property insurance.

2.5 Audio Output Considerations

WARNING: Audible signals may mask medical equipment
monitoring alarms. Where medical equipment monitoring alarms are
in use, do not use audible signals; provide visual notification
appliances in highly visible locations.

CAUTION: The output of the audio system may not be heard in all cases. Sound

can be blocked or reduced by walls, doors, carpeting, wall coverings, furniture,

insulation, bed coverings, and other obstacles that may temporarily or

permanently impede the output of the audio system. Sound is also reduced by

distance and masked by background noise.

The output of the audio system may not be sufficient to alert all occupants,

especially those who are asleep, those who are hearing-impaired, those who are

wearing devices that plug or cover the ears, and those who have recently used

drugs or alcohol.

The output of the audio system may not be heard by an alert person if the output

device is placed in an area which is isolated by a closed door, or is located on a

different floor from the person in a hazardous situation or is placed too far away

Series SPB Audio Boosters Manual, Revision A

Chapter 2: Safety Precautions

to be heard over ambient noise such as, but not limited to, running water, traffic,

air conditioners, machinery or musical appliances.

If live microphone announcements, audible tones and/or voice messages cannot

be readily heard and understood clearly within the protected areas as intended,

increase the number and/or sound output intensity of speakers within those areas

so that they are heard and understood clearly when activated.

2.6 RF Interference

The Series SPB Audio Booster panel has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user is required to correct the interference at his own
expense.

2.7 General

Each manufacturer's fire alarm control panel and notification appliances operate differently and
have different features. Before specifying, installing, operating, testing, maintaining, or servicing
a system, carefully read the installation, operation, and testing manual for each piece of
equipment and applicable codes.
