NOTES ON TANDEM INTERCONNECTING MODELS
w DO NOT connect Gentex CO alarms to other manufacturers' CO alarms.
w No more than 18 Gentex models CO1209 may be tandem interconnected.
w 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.
w After installation, to verify proper working conditions, all horns must sound in this
system.
w When tandem interconnecting CO1209 Series to additional CO1209 Series, S1209
or GN-503 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.
w Use red/yellow wire to tandem interconnect CO1209 alarms to Gentex legacy
products. The CO1209 Series can be tandem interconnected with the following
Gentex legacy products: 9123 Series, 7139CS Series, GN-300 and GN-303 Series.
w Use brown/yellow wire to tandem interconnect CO1209 Series alarms to additional
CO1209 Series alarms, S1209 Series and GN-503 Series.
w If the red/yellow wire is used to interconnect the CO1209 Series to additional
CO1209 Series, S1209 Series and GN-503 Series, the units will not be tandem
interconnected. The brown/yellow wire MUST be used.
w Do not tandem using both the red/yellow wire and brown/yellow wire. Only 1
tandem interconnect wire is needed between units.
NOTICE: IF A CO1209 OR GN-503 SERIES UNIT IS ANNUNCIATING FOR A CO
EVENT, LEGACY PRODUCTS WILL NOT ACTIVATE AND WILL REMAIN SILENT.
CAUTION: Failure to observe any of the conditions set forth may cause system
malfunction and damage to the alarm.
LIMITATIONS: Maximum of 18 CO alarms may be connected together. Do not
exceed 125 feet between each CO alarm. Do not exceed 1125 feet between the first
and last CO alarm.
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 ANSI/UL Listed Class 1 wire. Power limited cable for
multiple tandem connections is available at many commercial retail stores.
NOTICE: 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 metal outlet
boxes.

Tandem Installation
NOTICE: 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 18 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.
