For units that are used as single 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.
This alarm can share the interconnect wire of carbon monoxide, smoke and heat alarms. The
alarm will automatically sound a smoke alarm signal if smoke is detected by this unit or any
other interconnected smoke alarm, even if the unit is already detecting carbon monoxide and
sounding the carbon monoxide alarm signal.
Interconnected units can provide earlier warning of fire than stand-alone units, especially if a
fire starts in a remote area of the dwelling. This combination alarm may be interconnected
with as many as 11 other Universal model smoke alarms such as SS-795, SS-790, SS-911,
SS-2795, SS-2895 and SS-785 and 6 other units which may be a combination of Carbon
Monoxide Alarms such as CD-9385, CD-9390, CD-9485, CD-9490, Heat Alarms/HD-130 or Relay
Modules/RM-100 for a total of not more than 18 interconnected devices.
Interconnected CO alarms will only respond if a CO alarm/event initiates the alarm. All other
alarms remain silent.
NOTE: Relay modules/RM-100 will not respond if a CO alarm/event initiates the alarm.
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: Units without battery backup will not respond during an AC power failure.

The yellow wire is used only for multiple station operation with Universal Model alarms
only. Connecting this yellow wire to any other circuits may result in damage. When alarms
are interconnected, all units must be powered from a single AC branch circuit. If local
codes do not permit be sure the neutral wire is common to both phases. The maximum
wire run distance between the first and last alarm/device in an interconnected system is
1,000 feet. NOTE: Use standard household wire (18 gauge or larger, rated at least 300V, as
required by local codes) available at all electrical supply/hardware stores.
The wiring to be used shall be in accordance with the provisions of Articles 210 and
300.3(B) of the National Electrical Code, ANSI/NFPA 70. In addition, the resistance of the
interconnecting wiring shall be a maximum of 10 Ohms.
3. Attach the mounting plate to the electrical junction box.
4. Plug the AC QUICK CONNECTOR into the alarm base. Push and turn the alarm clockwise onto
the mounting plate.
