12. TROUBLESHOOTING GUIDE
Problem Possible cause Solution
Not all of the
alarms/accessories
produce an alarm
signal when the Test
button is pushed on
a unit.
Other interconnect-
ed hardwired alarms
do not sound.
Units signal an
alarm when no fire
is present and none
of the test buttons
have been pushed.
Units continue to
signal an alarm after
the smoke has been
removed from the
area or more than
60 seconds after a
test button was
pushed.
Devices may not all
be on the same ID.
Devices may not have
power.
Button not pressed
long enough.
There may be too
much interference
between units.
Wiring not installed
properly.
Unit is set to the
same ID as a system
nearby.
Unit is located in area
prone to cause false
alarms.
Electrical noise on the
interconnect line of
an AC alarm
Wireless Interference.
You have two RF-SM-
ACDC units installed
on the same inter-
connect circuit.
Locate the 8-position dipswitch on the back of each
unit and ensure that all of the corresponding switches
are set the same. If an ID needs to be changed:
Remove power, change the ID and reapply power.
Check to see if the Green LED is on continuously (this
tells you the alarm is receiving AC power) or that it
blinks every ten seconds (this tells you that it is receiving
only battery power). If not, make sure the batteries are
installed correctly and AC Quick Connector is installed
correctly. Contact a qualified electrician to check power
to the wires.
Press and hold the button for a minimum of 5 seconds.
Move the other units to a new location and try again.
You should try to locate the wireless units as closely to
each other as possible.
Turn off the power to the alarms’ circuit and ensure
that the wires are connected correctly. See section 3,
WIRING INSTRUCTIONS FOR AC QUICK CONNECTOR .
Change the ID of your units by following the instruc-
tions in Section 3, INSTALLATION INSTRUCTIONS, WIRE-
LESS INTERCONNECT SETUP. Make sure to turn power
off to all units before changing the switch positions.
Review section 2.LOCATIONS TO AVOID. Relocate the
unit.
Ensure that the smoke alarms are installed on a dedicat-
ed electrical circuit. A professional electrician may be
needed to correct a problem with the wiring.
Move the other units to a new location.
Only one RF-SM-ACDC unit can be connected to system
that uses a third wire to interconnect units. If two RF-
SM-ACDC units are connected to a wired interconnect
system they will interfere with each other’s transmis-
sions and can cause each other to alarm continuously.
