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 CONNECTORCONNECT TO

BLACK	"HOT" side of AC line
WHITE	"NEUTRAL" side of AC line
YELLOW	Interconnect wires of other smoke alarms

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 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) alarms; 6 other initiating smoke 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. Comparable models include: 2995, 5304, MI100, MI106, MH119, MH120, MDS101, MDS107, MDSS108, MDSCN103, MDSCN111, MPCN104, MPCN110, MCN105, MCN112, MCND114, MCND113, 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 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.
