The Feature Module does not
work.
The Feature Module is con-
nected properly, but the door
speaker does not work.
When you connect your Door
Intercom Adapter, the station
is not assigned as you wish, or
the magnetic lock does not
stay unlocked for the duration
you wish.
Other problems.
Check all connections and make sure that they are secure-
ly in place. Check to make sure that the status indicator
lamp is blinking. If it is not, unplug and then replug the AC
power cord. If the status indicator still fails to start blinking,
check your wall jack by plugging another device such as a
lamp into the outlet to make sure that the outlet is working
properly. Check to be sure that the feature module is con-
nected to the System’s line 1 telephone number.
The problem may be with the telephone wiring:
If possible, check your jack wiring by testing a telephone at
the jack where you installed the Feature Module. If this
standard telephone does not work, then local telephone
company lines or your own wiring may be causing the prob-
lem.
The problem may be with your door speaker:
Check to make sure that it is a Nutone brand door speaker
of model type ISB-64 or IS-69. Make sure that it is con-
nected properly to the wiring block (see page 19, and make
sure that the wiring block is securely connected to the Door
Intercom Adapter with the included 8-wire cord.
The problem may be with the DIP Switch settings on the
back of the module:
Please confirm that the DIP Switches on the back of the
Door Intercom Adapter are set properly. Refer to page 15
for instructions on setting them properly.
Make sure that you have followed the instructions in this
User’s Guide. If you continue to have problems, call TMC’s
toll-free customer support line at 1-800-TMC-1638.
