TROUBLESHOOTING

If an LED fails to respond:

1.

Check DS17 on the back of the module for
activity. If there is no activity, it means there
is a module with possible problems, such as
incorrect address, missing or incorrect
wiring, no power at the module, or some
system problem.

2.

Remove the module from its backbox to
examine the DS17 LED. 

Do not touch the

screw terminals to anything or damage
could result.

3.

Check the control panel for proper annuncia-
tion of the alarm, supervisory, or trouble
condition.

4.

Check the wiring between the module and
the control panel.

5.

Check the address setting on switch S1,
which is located on the back of the module.
Remove the module from its backbox to
examine S1.

6.

Check that there are 24 volts between the
TB1 terminals 

+24V

 and 

-V

.

7.

If the problem continues, replace the module.

8.

Check the new module for correct wiring and
check the address settings on S1 before
powering up the system.

If Fault Code 8 appears on the SXL-EX
display:

1.

The module is connected but is not configured.
Refer to the LED-3/4 Programming instructions.

2.

The module is configured but is not connected.
