Owner`s manual

For units that are used as single heat 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 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) 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: 2995, 5304,
MI100, MI106, MDS211, MDS201, 2985, 5303, MI200, MI210, MDS101, MDS107,
3885, 3895, MP118, MP117, 3303, 3304, MP202, MP212, MDSCN111, MDSCN103,
MICN109, MICN102, MCN105, MCN108, SS-785, SS-790, SS-795, SS-2795, SS-
2790, SS-2785, SS-2895, HD-130, USI-1103, USI-1203, USI-1204, USI-1208 (Part
#USI-1209), USI-1213, USI-2430, USI-3204, USI-5204, USI-5208, USI-5213, USI-
7385, USI-7390, USI-7485, USI-7490, CD-9385, CD-9390, CD-9485, CD-9490, CD-
9795, USI-7795 AND USI-960, RM-100 Relay.
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. Natural gas detection is only present in models
MDSCN111, MSDCN103, MICN109, MICN102, MCN108 and MCN105; therefore,
a natural gas alarm will NOT trigger the alarm of non-natural gas sensing
models within an interconnected system.
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.

2. Wiring Instructions:
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 main power to the circuit before wiring the heat alarm.
c. There are three pigtail leads (black, white and yellow) coming from the AC
QUICK CONNECTOR. The proper wire connection is as follows:
WIRES FROM QUICK CONNECTOR CONNECT TO
BLACK "HOT" side of AC line
WHITE "NEUTRAL" side of AC line
YELLOW Interconnect wires of other units
