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.
