TO DEACTIVATE THE LOCKING FEATURES: To remove the 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 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 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 CONNECTORCONNECT TO

BLACK

"HOT" side of AC line

WHITE

"NEUTRAL" side of AC line

YELLOW

Interconnect wires of other alarms

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.

IInterconnected 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 interconnected, 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 and 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. Compatible models include: 2995, 5304, MI100, MI106, MDS101, MDS107, MDS211, 2985, 5303, MI200, MI210 USI-1103, USI-1203, USI-1204, USI-1208 (Part #USI-1209), USI-1213, USI-3204, USI-7385, USI-7390, USI-7485, USI-7490, USI-7795, USI-2430, USI-960, SS-785, SS-790, SS-795, SS-2795, SS-2895, CD-9385, CD-9390, CD-9485, CD-9490, CD-9795, HD-130, RM-100.

Interconnected CO alarms or CO alarm circuit of combination smoke and CO and Natural Gas alarms will only respond if a CO alarm / event initiates the alarm. All other alarms remain silent.

Interconnected combination Natural Gas Alarms will only respond if a natural gas event initiated 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 and Natural Gas 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.

MICN109, MICN109L, MICN102, MICN102L specifications

Universal Security Instruments offers a versatile lineup of carbon monoxide and smoke detectors that provide essential safety features for any home or office environment. Among their popular models are the MICN102, MICN109L, MICN109, and MICN102L, each designed with advanced technology to ensure effective monitoring and protection against fire and carbon monoxide threats.

The MICN102 is a dual-sensor alarm, combining both smoke and carbon monoxide detection in a single unit. This compact device features an electrochemical sensor for precise CO detection, as well as an ionization smoke sensor that responds quickly to fast-flaming fires. With a loud alarm of 85 decibels, homeowners can rely on timely notifications in the event of emergencies. The MICN102 is also equipped with a test and silence button, allowing for easy routine checks and the ability to silence false alarms.

The MICN109L is an enhanced model that includes a voice alert feature. This model not only emits a loud alarm but also provides clear spoken alerts, indicating whether smoke or carbon monoxide has been detected, significantly improving user awareness and response times. With its user-friendly design, the MICN109L also has an easy-to-read display that shows the current CO levels, allowing users to stay informed about their indoor air quality.

The MICN109 shares many of the same core features found in the MICN109L, including the dual-sensor technology and 85-decibel alarm, but does not include the voice alert function. This model still offers reliable and efficient monitoring, making it an excellent choice for individuals looking for solid protection without additional features.

Lastly, the MICN102L combines the effective detection capabilities of the MICN102 with voice alerts similar to those in the MICN109L. This model is particularly beneficial for larger households or spaces where quick identification of the type of threat may be crucial. Features such as battery backup ensure continuous protection even during power outages, while the easy-to-install design allows for swift setup.

Across all models, Universal Security Instruments emphasizes user-friendly operation, reliability, and effective detection, providing peace of mind for families and individuals alike. With their modern design and advanced safety features, these units stand out as trusted guardians against fire and carbon monoxide hazards, reflecting Universal Security Instruments’ commitment to quality and safety.
