Troubleshooting

1.The bell output drops to about 3 volts in alarm.

The battery/bell circuit is protected by a PC board trace which may have burned open by reversal of the battery leads. It is on the back of the PC board just adjacent to the red & black battery leads. Send in for service if this occurs.

2.How do I remove the Keypad Sounder on Alarm?

The keypad sounder follows the Burg Output. If you need to remove the Keypad Sounder, then you must remove the Burg Output from that zone.

3.How do I activate Chime by Zone?

The Chime feature will automatically be assigned to all zones, except for the following:

3.Zones programmed as Home/Away with Delay.

Zones programmed as Exit/Entry

Followers

4.Zones programmed for 24 Hour Protection. To Activate/Deactivate the chime mode, Press A5.

4.When using a piezo on the Bell Output, it constantly buzzes.

This is due to the fact that there is a constant loop current flowing through the Bell circuit for supervision. To eliminate this, cut resistor R26 which is located directly above Terminal 9 just below the heat sink.

5.Where are the fuses?

The control panel incorporates advanced circuitry which automatically limits the current when an over current condition exists without the use of traditional fuses. The circuit will restore automatically when the over current condition is corrected.

6.The PGM Output Pulses in Alarm. When the PGM lug of the control panel is programmed for an Armed indication it also incorporates an Alarm Memory function which will indicate that the system is in an Alarm condition. If this output is being used to trigger a long range radio, it can be converted to a steady output with the use of a capacitor, negative to PGM Terminal 15, Pos to Aux. Pwr. Term 12. (220 mF Electrolytic Capacitor, 25 Volts. Increase to 470 mF if necessary)

7.I short out the bell and the system does not indicate Bell Trouble.

The Bell Supervision circuit is only designed to detect a "Bell Cut", it does not supervise for a short on the Bell.
