Figure 9
WIRING TWO OR MORE SMOKE ALARMS
(7109CS/CSX & 7139CS/CSX ONLY) Tandem Installation
NOTICE: All smoke alarms in 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 smoke alarm.
LIMITATIONS: A maximum of six (6) smoke alarms of model
(7109CS/CSX & 7139CS/CSX or models with the relay option (F, HF,
TF) may be tandem interconnected. Do not exceed 1125 feet
between first and last smoke alarm.
Wire used for interconnecting shall be in accordance with the
latest edition of Article 760 of the National Electrical Code (NEC) and
NFPA 70, and must not exceed a resistance of 10 ohms.
Figure 10
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
smoke alarms that are to be connected together. Use UL listed Class
1 wire. Power limited cable for multiple tandem connections are
available at many commercial electrical retail stores.
2. Make wire connections to supplied plug-in connector as follows:
black to black, white to white, 3rd conductor to red-yellow wire. The
red-yellow wire should be stripped to make this connection. Connect
ground wire between metal outlet boxes.

NOTES ON TANDEM INTERCONNECTING MODELS
DO NOT connect Gentex smoke alarms to other manufacturers'
smoke alarms.
No more than 12 Gentex models 9120/9123, 9120T/9123T, and
9120H/9123H may be connected in tandem.
No more than 6 Gentex models 7109CS/CSX & 7139CS/CSX,
9120F/9123F, 9120HF/9123HF, and 9120F/9123TF may be connected
in tandem.
All units connected in tandem MUST get their power from the same
circuit, that is, all smoke 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.
CAUTION: Failure to observe any of the conditions set forth may
cause system malfunction and damage to the smoke alarm.

BATTERY INSTALLATION

1. Remove smoke alarm from mounting plate by rotating counter-
clockwise.
2. Remove AC power connector and unsnap power leads from top of
the old battery. Snap new battery onto snaps and reinsert battery
through hole in back of smoke alarm.
3. Use only Duracell MN 1604 battery with the 7109/7139 Series
smoke alarms. Available at many retail stores.
CAUTION: Units with battery back-up will not provide power or
transmit an alarm to AC only units in the event of an AC power failure.
All battery back-up units in tandem, with good batteries, will operate
normally during an AC power failure. NOTICE: Visual signal will not
operate during AC power failure.
MOUNTING: PLATE & SMOKE ALARM
(7109CS/CSX & 7139CS/CSX ONLY)
1. Lace the connector through the provided mounting plate and secure
the plate to the junction box so that the smoke alarm snap-in tabs are
in the vertical position if wall mounted.
NOTE: Mounting plate is marked "THIS SIDE OUT" and slotted for
proper positioning.
Figure 12
2. Plug the wire connector into the smoke alarm base.
3. Place smoke alarm up to mounting plate, rotating it to about 10:00
o'clock then rotate it clockwise to 12:00. It should "snap-lock" firmly
into place. Keep smoke alarm parallel to mounting plate so upper and
lower tabs on plate seat into device.

MOUNTING: PLATE & SMOKE ALARM (7109LS/7139LS
ONLY) LINE CORD MODEL
Figure 14
The 7109LS/7139LS is supplied with a 9 foot line cord for
installation to a normal outlet. For this type of installation:
1. Care should be taken to lace cord through slots in base as shown
in Figure 14 to insure cord does not interfere with engagement of the
mounting bracket.
2. Determine proper location for smoke alarm above a receptacle that
is NOT CONTROLLED BY AN "ON-OFF" SWITCH.
3. If screw anchors are used, drill two 3/16" holes, insert the screw
anchors, and mount the plate to wall using screws.
4. Mount the smoke alarm to the bracket as illustrated in Figure 13.
5. Use the enclosed cord retainer clamp as illustrated in Figure 14
to insure the unit is not accidentally disconnected.
Place smoke alarm up to mounting plate, rotating it to about 10:00
o'clock then rotate it clockwise to 12:00. It should "snap-lock" firmly
