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 smoke 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
Early warning fire detection is best achieved by the installation of fire detection equipment in
all rooms and areas of the household as follows: A smoke alarm installed in each separate
sleeping area (in the vicinity of, but outside of, the bedrooms) and heat or smoke alarms in
living rooms, dining rooms, kitchens, hallways, attics, furnace rooms, closets, utility storage
rooms, basements and attached garages. Test the smoke alarm weekly to assure proper
operation.
3. Attach the mounting plate to the electrical junction box.
4. To activate 9 volt battery and alarm, hold the QUICK DRAW
(R)
battery drawer closed, pull and
remove the PULL-TAB. Discard PULL-TAB.
5. Plug the AC QUICK CONNECTOR into the alarm base. Push and turn the alarm clockwise
onto the mounting plate.
6. See "TAMPER LOCKING PIN."
For units that are used as single smoke 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 of fire than stand-alone units, especially if
a fire starts in a remote area of the dwelling. This smoke alarm may be interconnected with
as many as 11 other USI ELECTRIC model smoke alarms such as USI-1103, USI-1203, USI-
1204, USI-1209, USI-1213, USI-2204, USI-3204 and 6 other units which may be a combination
of Carbon Monoxide Alarms such as USI-7385, USI-7390, USI-7485, USI-7490, USI-7795, Heat
Alarms/USI-2430 or Relay Modules/USI-960 for a total of not more than 18 interconnected
devices.
Interconnected CO alarms will only respond if a CO alarm / event initiates the alarm. All other
alarms remain silent.
Interconnected smoke alarms, heat alarms and relay modules will only respond if a smoke
alarm / event or heat alarm / event initiates the alarm. All CO alarms remain silent.
Note that units without battery backup will not respond during an AC power failure.
NOTE: Relay Modules/USI-960 will not respond if a CO alarm / event initiates the alarm.

The yellow wire is used only for multiple station operation with USI ELECTRIC Model alarms
only. Connecting this yellow wire to any other circuits may result in damage. When alarms
are interconnected, all units must be powered from a single AC branch circuit. If local codes
do not permit be sure the neutral wire is common to both phases. The maximum wire run
distance between the first and last alarm/device in an interconnected system is 1,000 feet.
NOTE: Use standard household wire (18 gauge or larger, rated at least 300V, as required by
local codes) available at all electrical supply/hardware stores.
The wiring to be used shall be in accordance with the provisions of Articles 210 and 300.3(B)
of the National Electrical Code, ANSI/NFPA 70. In addition, the resistance of the interconnecting
wiring shall be a maximum of 10 Ohms.
