Troubleshooting
Phone Won’t Ring
Step
1.
Check the A: and B: attributes and the architectural number for the line and verify they are
correct (refer to the Programming Section).
Step 2.
Note:
Make sure pin 3 of the line hybrid is intact and the line hybrid is properly inserted.
For trunk lines, always cut pin
3
of the LLM serving a
COA.
Failure to do so will cause damage
to the COA.
Step
3.
The Direct Seizure Modification may be installed in Key systems with 4OOE cards. Check
wiring and ensure a common ground exists between the key system and the TCIV. Contact
Sales Engineering for more information on this modification. For new designs, consider using
the TCIV King Trip Adapter.
Step 4.
Step 5.
A faulty hybrid may be the problem, remove and replace it and then retest.
Another port may have the same architectural number, use the #72 function to see if another
number appears (refer to the Programming Section).
Time Tones Do Not Work
Step 1.
Step 2.
Connect jumpers from the Z terminal to the zone inputs on MIO. If no time tone go to Step 3.
If the tone activates, check the master clock and ensure it activates input by going lower than
. 6 vdc for .5 sec. If more than one zone, make sure the master clock activates all necessary
zones at the same time.
Step 3. Insure programming of locations Codes for length of Time Tones (64082 through 64096) is
correct for each zone
.
Step 4. Check amplifier input level to ensure it is not turned off. Check circuit breaker on amplifier.
Step 5. If MTG is installed, try manual activation with #ll thru #14.

Problem
Amplifier audio in/out can be traced through MI0 relays (refer to detail on Drawing KC 1461).
Relays can be operated using the computer and monitor functions explained earlier in this
section.
Step 1. Check for output from the LLM Port #2 and ensure the Fire Alarm Control Panel is reset, if a
USR2126 is installed.
Step 2. Ensure the MI0 is properly seated into its rear connector and that no connector pins are
bent.
Step 3.
Step 4.
Step 5.
Check the amplifier input level control and circuit breaker.
If using an electronic key phone, make sure it allows # as a first digit.
Use the computer aided diagnostics program to check receivers for proper decoding.
