THIS SMOKE ALARM WILL NOT WORK WITHOUT 120 VAC POWER AND A
GOOD BATTERY PROPERLY INSTALLED. THE SMOKE ALARM SHOULD BE
TESTED WHEN INSTALLED AND THEN TESTED WEEKLY AFTER THAT.
INSTALLATION INSTRUCTIONS: CAUTION!! READ CAREFULLY.
Installation of this alarm must conform to the electrical codes in your area; Article 760 of
the National Electrical Code, 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 alarm 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
alarm to a 24-hour circuit may prevent it from providing constant protection.
IMPORTANT: Do not subject this smoke alarm to megger, high voltage or high-pot tests.
Remove the smoke alarm(s) before high-potting tests occur on the circuit or system.
(Ref. Section 550-17, National Electrical Code, 2002 Edition).
ELECTRICAL SHOCK HAZARD
Turn off power to the area where you will install this alarm 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.
CAUTION: THIS SMOKE ALARM IS SEALED. THE COVER IS NOT REMOVABLE!
•A mounting bracket is provided on the back of the alarm.
•Remove the mounting bracket from the back of the alarm by holding the mounting bracket and

sleeping area (in the vicinity of, but outside of, the bedrooms); and, as appropriate, heat
or smoke alarms in living rooms, dining rooms, kitchens, hallways, attics, furnace rooms,
closets, utility storage rooms, basements and attached garages. Test the alarms weekly to
assure proper operation.
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.

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 models: MI106S, MIC1509S, MDSCN111,
MICN109, MCN108, USI-1103, USI-1203, USI-1204, USI-1208 (Part #USI-1209), USI-1213, USI-

3885, 3895, MP118, MP117, USI-2430, USI-960.
When any one of these interconnected models alarms it will trigger the corresponding alarm
within the interconnected system with respect to their sensing capabilities. Natural gas
detection is only present in models MDSCN111, MICN109, MDSCN103, MICN102, MCN105,
and MCN108, 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, CD-9795,
USI-7385, USI-7390, USI-7485, USI-7490, CD-9385, CD-9390, CD-9485, CD-9490.
The following alarms cannot trigger Quick Find®Alarm Origination on an interconnected

The following alarms can trigger Quick Find®Alarm Origination, but will not indicate Alarm
Origination on an interconnected system: USI-1103, USI-1203, USI-1204, USI-1208 (Part

Interconnected CO alarms or CO alarm circuit of combination smoke and 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 smoke alarms 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 operations with USI ELECTRIC or UNIVERSAL
Model alarms only. Connecting this yellow wire to any other circuits may result in damage
and alarm malfunction. When alarms are interconnected, all alarms must be powered from
a single AC branch circuit. If local codes do not permit, be sure the neutral wire is common
