DO NOT TAMPER WITH WIRES WHEN POWER IS ON!
For alarms 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 alarms can provide earlier warning of fire than stand-alone alarms, especially
if a fire starts in a remote area of the dwelling. When alarms are inter- connected, all alarms
will sound when one alarm first goes into alarm. This alarm may be interconnected with a
total of not more than 24 interconnected devices, i.e., as many as 11 other USI ELECTRIC
or UNIVERSAL model smoke alarms or combination smoke and carbon monoxide (CO) or
smoke and carbon monoxide / natural gas alarms;
6 other initiating alarms which may be a combination of USI ELECTRIC or UNIVERSAL CO
Alarms and Heat Alarms; and six other non-initiating devices such as USI ELECTRIC Relay
Modules.
This alarm can be interconnected with the following compatible alarms: MDSCN111CN,
MICN109CN, 5304CN, MI106CN, MDS107CN, MP117CN, USI-960, MI106SCN, MIC1509SCN,
MP116SCN, MPC122SCN, SLW127CN.
When any one of these
interconnected models goes into alarm, it will trigger the corresponding
alarm within the interconnected system with respect to their sensing capabilities. Natural gas
detection is only present in models MDSCN111CN, MDSCN103CN, MICN109CN, MICN102CN,
MCN108CN, and MCN105CN, therefore a natural gas alarm will NOT trigger the alarm of
non- natural gas sensing models within an interconnected system.
The following alarms cannot reset units on an interconnected system: USI-7795-CAN,
CD-9795-CAN, CD-9785-CAN, USI-7385, USI-7390, USI-7485, USI-7490, CD-9385, CD-9390,
CD-9485, CD-9490.
The following alarms cannot trigger Quick Find

system: USI-7385, USI-7390, USI-7485, USI-7490, CD-9385, CD-9390, CD-9485, CD-9490.
2. Insert the pin into the hole for the feature you are activating. Refer to the diagram below for
correct placement.
TO DEACTIVATE THE LOCKING FEATURES:
To remove the smoke alarm for cleaning or
servicing or to replace the battery, you must first remove the appropriate locking pin, if it has been
installed.
1. Turn off AC power to the circuit.
2. Use long nose pliers to pull the locking pin out of the hole.
3. It is now possible to remove the smoke alarm or replace the battery.
WIRING INSTRUCTIONS:
1. 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 AC power to the circuit before wiring the smoke alarm.
c. There are three pigtail wires (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 smoke alarms
