Installation Guide

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 ANSI/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.
MOUNTING: PLATE & SMOKE ALARM (7139LS ONLY) LINE CORD
MODEL
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.
The 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 above diagram 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.
5. Use the enclosed cord retainer clamp as illustrated, 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 into place. Keep smoke alarm parallel to the
mounting plate so upper and lower tabs on the plate seat into the smoke alarm.
CAUTION: Failure to observe any conditions set forth may cause system malfunction and
damage to smoke alarm.
CHECKOUT & TROUBLESHOOTING
1. Turn test knob to the NORMAL position and supply house power to the smoke alarm.
The
red indicator should flash every 15-30 seconds, showing that the smoke alarm is
operating properly.
2. If red light is not flashing or the green LED is not on:
a. Check that the battery is installed.
b. Check to see if the plug is in the outlet.
c. If the power and wiring check out, but the red light does not flash or the green LED is
still off, return the device to the manufacturer. See TO RETURN A SMOKE ALARM.
3. Testing with the Test Knob:
a. Rotate test knob counter-clockwise to TEST 1 position, wait up to 20 seconds for
smoke alarm to sound and visual signal flash. If device does not sound after 20
seconds, return device for service.
b. After successfully testing smoke alarm, return test knob to NORMAL (non-test)
position and wait 20 seconds for the smoke alarm to stop sounding.
NOTICE: TANDEM INTERCONNECTING MODELS
w DO NOT connect Gentex smoke alarms to other manufacturers' smoke alarms.
w No more than 12 Gentex models 9123, 9123T and 9123H may be connected in tandem.
w No more than 6 Gentex models 7139CS, 9123F, 9123HF and 9123TF may be connected
in tandem.
w 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.
w After installation to verify proper working conditions all horns must sound in this system.
NOTICE: IF ALL INTERCONNECTED ALARMS DO NOT EMIT ALARM SIGNAL DURING
COMMISSIONING TEST, REFER TO “WIRING TWO OR MORE SMOKE ALARMS”
SECTION TO INSURE ALARM WIRING IS IN ACCORDANCE WITH TANDEM WIRING
DIAGRAM.
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 7139CS and 7139LS 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 (7139CS 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.
NOTICE: MOUNTING PLATE IS MARKED "THIS SIDE OUT" AND SLOTTED FOR
PROPER POSITIONING.
