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.

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: MI106S, MIC1509S, MDSCN111,
MICN109, MCN108, USI-1103, USI-1203, USI-1204, USI-1208 (Part #USI-1209), USI-1213, USI-
5204, USI-3204, SS-785, SS-790, SS-795, SS-2795, SS-2895, USI-7385, USI-7390, USI-7485,
USI-7490, CD-9385, CD-9390, CD-9485, CD-9490, CD-9795, USI-7795, 5304, MI106, MDS107,
3885, 3895, MP118, MP117, USI-2430, USI-960.
When any one of these interconnected models alarms 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, MICN109, MDSCN103, MICN102, MCN105,
and MCN108, therefore a natural gas alarm will NOT trigger the alarm of non- natural gas
sensing models within an interconnected system.
The following alarms cannot reset units on an interconnected system: USI-7795, CD-9795,
USI-7385, USI-7390, USI-7485, USI-7490, CD-9385, CD-9390, CD-9485, CD-9490.

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.
The yellow wire is used only for multiple station operations with USI ELECTRIC or UNIVERSAL
Model alarms only. Connecting this yellow wire to any other circuits may result in damage
and alarm malfunction. When alarms are interconnected, all alarms must be powered from
a single AC branch circuit. If local codes do not permit, be sure the neutral wire is common
