The horn will not work without power. The horn gets its power from the fire/security
panel monitoring the alarm system. If power is cut off for any reason, the horn will not
provide the desired audio or visual warning.
The horn may not be heard. The loudness of the horn meets (or exceeds) current
Underwriters Laboratories’ standards. However, the horn may not alert a sound sleeper or

one who has recently used drugs or has been drinking alcoholic beverages. The horn may
not be heard if it is placed on a different floor from the person in hazard or if placed too
far away to be heard over the ambient noise such as traffic, air conditioners, machinery
or music appliances that may prevent alert persons from hearing the alarm. The horn
may not be heard by persons who are hearing impaired.

fCC STATEMENT

SpectrAlert Strobes and Horn/Strobes have been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the equip-
ment 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 will be required to correct the interference at his own expense.
