INSTALLATION AND OPERATION
INSTALLATION INSTRUCTIONS: CAUTION!! READ CAREFULLY.
CAUTION: THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE!
• This combination smoke/CO alarm requires constant 120 Volt AC power AND/OR a working
9 Volt battery to operate properly. This combination smoke/CO alarm WILL NOT work if AC power
is not connected or if it has failed or been interrupted for any reason AND the battery is removed,
drained or improperly connected. DO NOT use any other kind of battery except as specified in
this manual.
NOTE: AC/DC combination alarms offer added protection in the event of a power failure or a
drained battery.
• Test alarm immediately following installation and weekly for proper operation by pushing the
test button. The alarm will then test itself for proper operation. The alarm then resumes normal
operation.
• A mounting plate is provided on the back of the alarm.
• Remove the mounting plate from the back of the alarm by holding the mounting plate and twisting
the alarm in the direction indicated by the "TURN TO REMOVE" arrow on the side of the alarm
base.
Installation of this unit must conform to the electrical codes in your area; Article 760 of the
National Electrical Code, NFPA 720/CO Alarms, NFPA 72, 101; SBC (SBCCI); UBC (ICBO);
NBC (BOCA): OTFDC (CABO), and any other local or building codes that may apply. Wiring
and installation must be performed by a licensed electrician. Failure to follow these guidelines
may result in injury or property damage.
This unit must be powered by a 24-hour, 120V AC 60Hz circuit. Be sure the circuit cannot be
turned off by a switch, dimmer or ground fault circuit interrupter. Failure to connect this unit
to a 24-hour circuit may prevent it from providing constant protection.
IMPORTANT: Do not subject this alarm to megger, high voltage or high-pot tests. Remove the
alarm(s) before high-potting tests occur on the circuit or system. (Ref. Section 550-17, National
Electric Code, 2002 Edition).

ELECTRICAL SHOCK HAZARD
Turn off power to the area where you will install this unit at the circuit breaker or fuse box
before beginning installation. Failure to turn off the power before installation may result in
serious electrical shock, injury or death.
TAMPER LOCKING PIN: To make your alarm somewhat tamper resistant, a locking pin has been
provided (break-away part of mounting plate). Using this tamper pin will deter children and others
from removing the alarm from the mounting plate. To use the tamper pin, insert it into the hole in the
side of the alarm after the alarm has been installed on the mounting plate. Using long nose pliers,
pull the tamper pin out of the hole. It is now possible to remove the alarm from the mounting plate.
1. Turn the alarm counterclockwise in the direction indicated by the "TURN TO REMOVE" arrow
on the side of the alarm base to remove it from the mounting plate. NOTE: The alarm is sealed
and the cover is not removable.
2. Wiring Instructions:
a. The appropriate power supply is 120 Volt single phase power supplied from a non-switchable
circuit NOT protected by a ground fault circuit interrupter.
b. Turn off main power to the circuit before wiring the alarm.
c. There are three pigtail leads (black, white and yellow) coming from the AC QUICK
CONNECTOR. The proper wire connection is as follows:
WIRES FROM QUICK CONNECTOR CONNECT TO
BLACK "HOT" side of AC line
WHITE "NEUTRAL" side of AC line
YELLOW Interconnect wires of other units
