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 ser-
vice if this occurs.
2. How do I remove the Keypad Sounder
on Alarm?
The keypad sounder follows the Burg Out-
put. 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 follow-
ing:
1. Zones programmed as Home/Away
with Delay.

Zones programmed as Exit/Entry
Followers
2. Zones programmed for 24 Hour Pro-
tection. To Activate/Deactivate the
chime mode, Press
.
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 cur-
rent 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 Elec-
trolytic 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 de-
signed to detect a "Bell Cut", it does not
supervise for a short on the Bell.
