Procedure H
If the green system normal LED is off, the amber system trouble LED is on, and the amber trouble indicator LED flashes a 6-blink
pattern, a ground fault has been detected. A ground fault detected error may be caused by:
1.
Contact input wiring shorted to earth ground.
2. DV-EM cable wiring shorted to earth ground.
3. RS-232 or RS-485 wiring shorted to earth ground.
4. Input power wiring shorted to earth ground.
5. Ground fault detection sensitivity is set too high.
6. Failed ground fault detection circuitry on AVL-1.
If the error was due to one of the first five causes, the trouble will clear automatically when the cause is corrected.
When a ground fault detected error is indicated, perform the following:
1.
Check all contact input wiring for ground faults.
2. Check all DV-EM cabling for ground faults.
3. Check all RS-232 and RS-485 wiring for ground faults.
4. Check all input power wiring for ground faults.
5. Decrease the ground fault detection sensitivity level, following the adjustment procedure set forth in the Ground Fault
Detection Sensitivity Adjustment section of this manual.
If, after the above procedure is completed, the trouble condition persists, the trouble condition is caused by failed circuitry on the
AVL-1. There are no field correctable failed circuitry problems on the AVL-1. AVL-1's with failed circuitry shall be replaced
immediately, following the Replacement Procedure, set forth previously in this section.
Procedure I
If the green system normal LED is off, the amber system trouble LED is on, and the amber trouble indicator LED flashes a 1-blink
pattern, a battery trouble has been detected. A battery trouble error may be caused by:
1.
Disconnected memory retention battery.
2. Failed memory retention battery.
3. Failed battery charging or supervision circuitry on the AVL-1.
If the error was due to one of the first two causes, the trouble will clear the first time the battery is checked after the cause is
corrected. Note that the battery is checked by the circuitry once every five minutes.
When a battery trouble error is indicated, perform the following:
1.
Check connection of memory retention battery.
2. Replace memory retention battery.
If after the above procedure is completed, the trouble condition persists, the trouble condition is caused by failed circuitry on the
AVL-1. There are no field correctable failed circuitry problems on the AVL-1. AVL-1's with failed circuitry shall be replaced
immediately, following the Replacement Procedure, set forth previously in this section.
Procedure J
If the green system normal LED is off, the amber system trouble LED is on, and the amber trouble indicator LED flashes a 7-blink
pattern, a telephone trouble has been detected. A telephone trouble error may be caused by:
1.
Blown Fuse (F1).
2. Incorrect call progress tones on telephone line.
3. Insufficient off hook voltage on telephone line.
4. Disconnect telephone line.
5. Missing or improperly installed Telephone Interface Kit integrated circuits.
6. A telephone message has gone unacknowledged for three consecutive times to one telephone number.
7. Failed circuitry on the digital voice module.
When a telephone trouble error is indicated, perform the following:
1.
Check fuse (F1) on digital voice module.
2. Verify that the telephone line is connected properly.
3. Verify that the two Telephone Interface Kit integrated circuits have been installed properly.
4. Verify that all activated telephone messages have been acknowledged and are no longer playing.
5. Verify that there is voltage across the telephone line when a telephone message is selected to play.
6. Verify that the telephone provides a standard dial tone when off hook and a standard ring when dialing.
If after the above procedure is completed, the trouble condition persists, reset the digital voice announcer. Activate one telephone
message and verify that it executes correctly. If the telephone message fails to play correctly and there are no problems with the
telephone line, the telephone trouble condition is caused by failed circuitry on the digital voice module.
There are no field correctable failed circuitry problems on the digital voice module. Digital voice modules with failed circuitry shall
be replaced immediately, following the Replacement Procedure, set forth previously in this section.
