25 ohms or less per interconnecting wire.
Secure the APA151 to the single gang box using the two
screws provided, or directly to the wall or ceiling.
The sounder will not operate if the power is cut off for any reason.
The sounder may not be heard. The loudness of the sounder meets or exceeds the cur-
rent standards. However, the sounder may not alert a sound sleeper or one who has
recently used drugs or has been drinking alcoholic beverages. This sounder may not
be heard if it is placed in an area that is separated by a closed door, or if it is located
on a different floor from the person in a hazardous situation, or if it is placed too far
WARNING
The Limitations of Sounders
away to be heard over ambient noise, such as, traffic, air conditioners, machinery or
musical appliances that may prevent alert persons from hearing the alarm.
The sounder may not be heard by persons who are hearing-impaired. In this case, a
visual indicator shall also be used.
For these reasons, Pittway recommends that sounders (85dBA minimum at 10 feet)
used in a residence shall be placed on every level and in every bedroom that does not
have a smoke detector with a built-in sounder.

Please include a note describing the malfunction and suspected cause
of failure. The Company shall not be obligated to replace units which
are found to be defective because of damage, unreasonable use, modi-
fications, or alterations occurring after the date of manufacture. In no

damages for breach of this or any other Warranty, expressed or implied
whatsoever, even if the loss or damage is caused by the Company’s
negligence or fault. Some states do not allow the exclusion or limita-
tion of incidental or consequential damages, so the above limitation or
exclusion may not apply to you. This Warranty gives you specific legal
rights, and you may also have other rights which vary from state to state.
