NOTE:
For any location, make sure no door or other obstruction could prevent the carbon monoxide
or gas from reaching the alarm.
WHERE THIS ALARM SHOULD NOT BE INSTALLED
To avoid causing damage to the unit, to provide optimum protection, and to prevent
unnecessary alarms. Do NOT locate this alarm:
•
,QJDUDJHVNLWFKHQVFUDZOVSDFHVDQGXQ¿QLVKHGDWWLFV$YRLGH[WUHPHO\GXVW\GLUW\RUJUHDV\
areas. Installation in these areas could lead to nuisance alarms, may expose the sensor to
substances which could damage or contaminate it, or the alarm may not be heard by people in
other areas of the home, especially if they are sleeping.
•
In the garage, vehicle exhaust can contain some carbon monoxide. These levels are higher when
WKHHQJLQHLV¿UVWVWDUWHG:LWKLQKRXUVRIVWDUWLQJDYHKLFOHDQGEDFNLQJLWRXWRIWKHJDUDJHWKH
levels present over time can activate the alarm and become a nuisance.
•
In the kitchen, some gas appliances can emit a short burst of CO or gas upon startup. This is
normal. If your CO and Natural Gas Alarm is installed too close to these appliances, it may alarm
often and become a nuisance.
•
Keep alarms at least 20 feet (6m) from the sources or combustion particles (stove, furnace,
water heater, space heater), if possible. In areas where a 20 foot (6m) distance is not possible
(in modular, mobile or smaller homes for example), it is recommended the alarm be placed as far

Ventilate these areas as much as possible.
If you must install the alarm near a cooking or
heating appliance, install at least 5 feet (1.5m) from appliance.

•
In extremely humid areas. This alarm should be at least 10 feet (3m) from a bath or shower,

•
In turbulent air, such as near ceiling fans, heat vents, air conditioners, fresh air returns or open
windows. Blowing air may prevent CO or natural gas from reaching the sensors.
•
Good ventilation is recommended when household cleaning supplies or similar contaminants
are used.

THIS ALARM WILL NOT WORK WITHOUT 120 VAC POWER AND A GOOD
BATTERY PROPERLY INSTALLED. THE 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 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 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 CO AND NATURAL GAS ALARM IS SEALED. THE COVER IS
NOT REMOVABLE
!
• A mounting bracket is provided on the back of the alarm.
• The alarm deactivation key will not be used for this model.
• Remove the mounting bracket from the back of the alarm by holding the mounting bracket and

the alarm base.
OPTIONAL TAMPER RESISTANT FEATURES:
There are two separate tamper resistant locking
features provided for this model. Activating one or both of these features deters someone from
removing the alarm from the mounting bracket or removing the battery from the alarm. The
breakaway locking pins are clearly marked and molded into the mounting bracket. Refer to the
diagram on the next page.
TO ACTIVATE THE LOCKING FEATURES:
Do not activate the locking features until you have
activated the battery, mounted the alarm to the bracket and tested the alarm. Refer to OPERATION,
TESTING & MAINTENANCE instructions on Page 6.
1. Detach the breakaway alarm locking pin from the mounting bracket.
TO DEACTIVATE THE LOCKING FEATURES:
To remove the alarm for cleaning or servicing or to

DO NOT TAMPER WITH WIRES WHEN POWER IS ON!
For alarms that are used as single non-interconnected, stand-alone 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.
INTERCONNECTION & COMPATIBILITY: Interconnected alarms can provide earlier warning
than stand-alone alarms, especially if a hazard is present in a remote area of the dwelling.
When alarms are interconnected, all alarms will sound when the initiating alarm sounds,
providing more time to escape safely. 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
brand model smoke alarms or combination smoke and carbon monoxide (CO) alarms or
smoke and carbon monoxide/natural gas alarms; 6 other initiating alarms which may be
a combination of USI Electric or Universal brand CO alarms and heat alarms; and 6 other
non-initiating devices such as USI Electric brand relays.
This alarm can be interconnected with the following compatible alarms: MDSCN111, MICN109,
MCN108, SS-2895, USI-1103, USI-1204, USI-1208, USI-1209, USI-5204, USI-3204, USI-7795,
5304, MI106, MDS107, MP117, USI-2430, USI-960, MI106S, MIC1509S.
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.
Interconnected CO alarms, or the CO alarm circuit of combination smoke, CO and natural gas
alarms, will only respond if a CO alarm event initiates the alarm. All other alarms remain silent.
Interconnected combination CO and natural gas alarms will only respond if a natural gas
event initiated the alarm. All other alarms remain silent. Natural gas detection is only present
in models MDSCN111, MICN109, MCN108; therefore, a natural gas alarm will NOT trigger the
alarm of non-natural gas sensing models within an interconnected system.
The following alarms can trigger Quick Find® Alarm Origination, but will not indicate
Alarm Origination on an interconnected system: USI-1103, USI-1204, USI-1208,
USI-1209, USI-1213, USI-5204, USI-3204, USI-2430, USI-7795.
The following alarms cannot be reset through an interconnected system because they do
not have Quick Find® Alarm Origination: USI-1103, USI-1204, USI-1208, USI-1209,
USI-5204, USI-3204, USI-2430, USI-7795.
Interconnected smoke alarms, heat alarms and relays will only respond if a smoke alarm
event or heat alarm event initiates the alarm. All CO and natural gas alarms remain silent.
NOTE: Alarms without battery backup will not respond during an AC power failure.
NOTE: The relay, model USI-960, will not respond if a CO or natural gas alarm event initiates
the alarm.
