electrician.
MOUNTING OUTLET BOX
Use a 2" x 3" switch box or a 4" square or octagon junction box.
Mount a box for each CO alarm. If wall mounting is desired, be sure
the box screws are oriented to upper right and lower left corners. Be
sure to use supplied Mounting Plate.
WIRING ONE ALARM
1. Run a minimum of 16 gauge, 2-conductor cable, plus ground (3
wires) to the junction box from a power supply. CO alarms shall
be connected to their own dedicated circuit. Use UL Listed Class
1 wire.
NOTE: The wiring to be used shall be in accordance with the
provisions of Article 300.3(b) 210 of the National

WIRING TWO OR MORE ALARMS

Tandem Installation

NOTE: All CO alarms in a tandem installation must be controlled by the same fuse or circuit breaker. Otherwise tandem units will not operate. Tandem will operate in the event of AC power failure if battery is connected to the CO alarm.

LIMITATIONS: A maximum of 12 CO alarms (CO1209) may be connected together. Do not exceed 125 feet between each device. Do not exceed 1125 feet between first and last CO alarm.

Wire used for interconnection shall be in accordance with article

760 of the latest edition of National Electrical Code (NFPA 70) and must not exceed a resistance of 10 ohms.

1. Run a minimum of 16 gauge, 3-conductor cable, plus ground (4
wires) to the first junction box from a power supply and between
all CO alarms that are to be connected together. Use UL Listed
Class 1 wire.
NOTE: When using both tandem connections, 4-conductor
cable, plus ground (5 wires) will be used.
2. Make wire connections to the supplied plug-in connector as
follows: black to black, white to white, 3rd conductor to the
red/yellow wire for legacy Gentex products or the brown/yellow
wire for new. The red/yellow wire or brown/yellow wire should be
stripped to make the connection. Connect ground wire between

NOTES ON TANDEM INTERCONNECTING MODELS

￿ DO NOT connect Gentex CO alarms to other manufacturers' CO alarms.

￿ No more than 12 Gentex models CO1209 may be tandem interconnected.

￿ All units connected in tandem MUST get their power from the same circuit, that is, all CO alarms in tandem must be controlled by the same fuse or circuit breaker.

￿ After installation, to verify proper working conditions, all horns must sound in this system.

￿ When tandem interconnecting CO1209 Series to additional CO1209 Series, GN-503 Series or GN-403 Series and the smoke alarm horn sounds but are not synchronized and the CO horn does not sound the red/yellow wire has been used. Use brown/ yellow wire.

￿ Use red/yellow wire to tandem interconnect CO1209 alarms to Gentex legacy products. Legacy products include 9120/9123 Series, 7100/7103 Series, 710CS/713CS Series, 7109CS/7139CS Series, GN-200/GN-203 Series and GN-300/GN-303 Series.

￿ Use brown/yellow wire to tandem interconnect CO1209 Series alarms to additional CO1209 Series alarms, GN-403 Series and GN-503 Series.

￿ If the red/yellow wire is used to interconnect the GN-503 Series to additional GN-503 Series, GN-400/GN-403 Series and CO1209 Series, the units will not be tandem inteconnected. The brown/ yellow wire MUST be used.
