1. Run a minimum of 16 gauge, 3-conductor cable, plus ground
(4 wires) to the first alarm junction box from a power supply
and between all smoke alarms that are to be connected together.
Use U.L. listed Class 1 wire.
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. 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 MasterGuard Smoke Alarms to other
manufacturers' smoke alarms.
No more than 6 MasterGuard Models 380LS-C 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.
IMPORTANT WARNING:
Failure to observe any of the
conditions set forth may cause system malfunction and damage to
the smoke alarm.
MOUNTING: PLATE & SMOKE
ALARM
1. Lace the connector through the provided mounting plate and
secure the plate to the junction box.
NOTE: Mounting plate is marked "THIS SIDE OUT" and slotted
for proper positioning.

IMPORTANT WARNING:
Failure to observe any of the conditions set forth may cause
system malfunction and damage to the 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 that the wire connector is fully seated.
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 the test knob counter-clockwise to the TEST 1 position
and wait up to 20 seconds for the alarm to sound. If the
device does not sound after 20 seconds, return the smoke
alarm 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.
Figure 14
c. To test smoke alarm for high sensitivity, turn test knob
clockwise to TEST 2 position. Alarm should remain silent.
Return knob back to the normal position. If your smoke alarm
sounds during this test it means the device's sensitivity has
become too high and may cause false alarms. This could
mean your smoke alarm is dirty and should be cleaned as
described in the maintenance procedure below. If the smoke
alarm continues to alarm for TEST 2 position following
cleaning return it to MasterGuard for service.
d. To check for proper smoke entry into your smoke alarm's
sensing chamber. MasterGuard recommends using the
Home Safeguard Smoke Alarm spray.
This test should be
performed once a year and should be sprayed from a
distance no closer than 12 inches from smoke alarm.
MAINTENANCE
After your smoke alarm has been in operation for a period of time
or if it was installed prior to the completion of all building
construction, your smoke alarm may have become more sensitive
due to dirt build-up in the smoke alarm's optic sensing chamber
which could cause nuisance alarms or could cause activation from
small amounts of smoke build-up.
If this should occur, following this simple washing procedure will
restore your smoke alarm back to its original condition.
For further information, regarding frequency of cleaning and
testing, refer to NFPA 72, NFPA, Batterymarch Park, Quincy, MA
02269.
IMPORTANT: Failure to follow full cleaning instructions
could result in damage to this smoke alarm. DO NOT remove
all alarms at the same time for cleaning.
1. Rotate the smoke alarm counter-clockwise to remove it from its
mounting plate.
2. Unplug the wire connector from the smoke alarm and remove the
battery.
2. Plug the wire connector into the smoke alarm base.
3. Place the smoke alarm up to the 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 the alarm parallel to the
mounting plate so upper and lower tabs on the plate seat into the
smoke alarm.
