INSTALLATION AND OPERATION
INSTALLATION INSTRUCTIONS: CAUTION!! READ CAREFULLY.
CAUTION: THIS UNIT IS SEALED. THE COVER IS NOT REMOVABLE
!
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.
Test alarm immediately following installation
and weekly for proper operation by
pushing the test button. The alarm will then test itself for proper operation and the red
LED indicator will flash on two 4-pulse patterns and the alarm will simultaneously sound
two 4-pulse patterns. The alarm then resumes normal operation.
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 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.
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. Using this pin will deter children and others from removing the alarm
from the mounting plate. To use the pin, insert it into the hole in the side of the alarm after
it has been installed on the mounting plate. Using long nose pliers, pull the 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
For units that are used as single alarms, do not connect the yellow wire to anything.
Insulate this wire (tape it) in place to make certain the yellow wire cannot contact any
metal parts.
Interconnected units can provide earlier warning than stand-alone units, especially if
dangerous CO (carbon monoxide) levels start in a remote area of the dwelling. This
unit will interconnect with ALL USI ELECTRIC AC carbon monoxide alarms, smoke
alarms, heat alarms and relay modules. A maximum of 18 units can be interconnected,
but there can be no more than 12 interconnected smoke alarms.
