15.0 Troubleshooting Guide

The D6600 consists of several plug-in assemblies that you can easily replace in the field (components and
controls on individual assemblies are shown starting in Section 3.0 Card Functions and Locations on page 4).
Do not attempt to repair individual assemblies. Return any failed assemblies to Bosch Security
Systems, Inc. for testing and repair. Use this Troubleshooting Guide to identify failed modular
components.

Symptom Problem
Line Card OL/LF Telephone line, telephone
LED steadily glows connecting cord, line card, or
red or yellow. telco terminator is defective.
Take immediate action if a telephone line is out of order and is the first line in a rotary or hunt
group. Ask the telephone company to create a busy signal on the defective line at the telephone
exchange.
If emergency service is not available, call the troubled line and leave the calling handset off the
hook. Do not hang up. Incoming alarm signals see a busy signal and rotor (hunt) to another line in
the hunt group. This procedure does not work for Wide Area Telephone Service (WATS) lines.

Solution
•
Pull the line card out of the receiver, and re-insert it to ensure
the card is properly connected.
•
Exchange the connecting cord with a telephone line that
operates. If the original OL/LF LED remains a steady red or
yellow, the problem is with a plug-in card. Replace the line
card with a spare. If the OL/LF LED for the new card is a
steady red or yellow, change the line terminator card.
•
If the OL/LF LED on the original troubled card goes out and
the OL/LF indicator on the previously untroubled card lights
when you swap connecting cords, the trouble is with the
telephone line. Replace the telco line connecting cord.
If the OL/LF LED is still on, the trouble might
be in the telephone line. Report the trouble to
the telephone company.
