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.

The yellow wire is used only for interconnect (multiple station operations) USI Electric or
Universal model alarms. Connecting this yellow wire to any other circuits may result in
damage and alarm malfunction. All interconnect alarms must be powered from a single circuit.
If local codes do not specify, be sure the neutral wire is common to all alarms. The maximum

required by local codes. This wire is commonly available at most electrical supply and

The alarm wiring shall be in accordance with the provisions of Articles 210 and 300.3(B) of

Alarm. Actual backup time depends on the strength (freshness) of the battery. The battery backup
will not work unless a good battery is properly installed.
When the alarm utilizes battery backup power, the natural gas sensor will operate the alarm and will
sample less frequently to extend battery life. Natural gas could be present during this period between
samples without the alarm sounding, especially if there is a rapid buildup of natural gas.

OPERATION, TESTING & MAINTENANCE
OPERATION:
The alarm is operating once the AC power is connected and turned on.
READY/ACTIVE CONDITION:
The green LED is on and blinks off once approx. every 20 seconds
to indicate the alarm is properly functioning.
GREEN LED:
The green LED is off and blinks on approx. every 40 seconds whenever AC power
is turned off.
CO ALARM:
The alarm signal is 4 beeps, 5 second pause, repeat. The red LED blinks on in sync
with the cycle of 4 beeps.
GAS ALARM:
The alarm signal is 1 beep, 2 second pause, repeat. The blue LED blinks on in
sync with the horn beep.
NUISANCE ALARM:
If the horn signals and the red or blue LED’s blink on for no apparent reason
and no obvious hazard is present, please verify that the alarm is mounted in the correct location.
Reset the alarm as instructed in the Operational Summary.
CO ALARM LATCHING LED INDICATOR:
The alarm had previously detected CO and had alarmed.
The red LED is off and blinks on approx. every 5 seconds until reset. Follow the reset instructions
to remove the latching LED.
WHAT TO DO IF CARBON MONOXIDE IS DETECTED:
Actuation of your CO Alarm indicates the presence of carbon monoxide (CO), which can kill you.
In other words, when your CO Alarm sounds, you must not ignore it!
Some individuals are more sensitive to CO than others, including people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers or elderly people can be more quickly and
severely affected by CO. Members of sensitive populations should consult their doctors for advice
on taking additional precautions.
Page 8
If you hear the alarm horn sound 4 beeps, a 2 second pause (and then repeat),
carbon monoxide has been detected. Evacuate everyone from the building.
GAS ALARM LATCHING LED INDICATOR:
The alarm had previously detected GAS and had
alarmed. The blue LED is off and blinks on approx. every 5 seconds until reset. Follow the reset
instructions to remove the latching LED.
TROUBLE / SERVICE ALARM:
Periodically, the alarm measurement circuit is tested. If an error is
detected, the alarm will sound 3 chirps approx. every 20 seconds. Reset the alarm. If the unit does not
reset, replace the alarm.
END-OF-SERVICE LIFE ALARM:
When it is time to replace your alarm, which is approximately 7 years
of operation from initial power up, the alarm will sound 2 chirps approx. every 20 seconds. Replace
DODUPLPPHGLDWHO\7KHSURGXFWHQGRIVHUYLFHOLIHQRWL¿FDWLRQFDQEHWHPSRUDULO\VLOHQFHGIRUDKRXU
period for up to 20 days. After 20 days, the warning cannot be silenced. The alarm should be replaced
immediately.
RESET THE ALARM:
Press the TEST/SILENCE button for 10 seconds, or until the blue LED turns on,
and then release. This will clear the alarm latching LED’s and clear the alarm origination. Reset after
each alarm event.
TESTING:
Test by pushing the Test button on the alarm cover until the alarm sounds, then release. The
alarm will sound 4 beeps, approx. 5 second pause, 1 beep. The test sequence lasts approx. 7 seconds.
The alarm sounds if all electronic circuitry and horn are working. If no alarm sounds, the alarm may have
a power supply failure.
Test the alarm weekly to assure proper operation.
ALARM ORIGINATION:
Patented Quick Find® Alarm Origination—In an interconnected system consisting
of any of these models: MI106S, MIC1509S, 5304, MI106, MDS107, MCN108, MICN109, MDSCN111,
03LWPD\EHGLI¿FXOWWRGHWHUPLQHZKLFKDODUPLQLWLDWHGWKHDODUPVWRVRXQGGXULQJDQDODUPHYHQW
This Quick Find® feature will immediately allow you to locate the originating alarm once the alarms have
stopped sounding. To initiate Quick Find®, press and hold the test/silence button on any alarm until the
WHVWVHTXHQFHRQWKLVDODUPEHJLQV5HOHDVHWKHWHVWEXWWRQ7KHVSHFL¿FKRUQSDWWHUQVHTXHQFHLV
designated by the alarm type. Once this test sequence ends, the originating alarm continues to sound
for approximately 60 seconds, which provides ample time to locate the originating alarm. Remember to
reset the originating alarm in order to clear the Quick Find® alarm origination, and to return your system to
normal operation. Refer to the wiring instructions/model interconnect compatibility section of this manual
