22.4 Remote Receiver/Driver Functions Inoperative

22.5 No Alarm Response

22.6 CPU Software Version Numbers

Bosch Security Systems, Inc.
1.
All receiver/drivers and functions inoperative: Verify power LED indicator on
Signal Distribution Unit is lit. If not, check fuses on front of main CPU bay power
supply. Verify the Code LED indicator flickers when control is activated by the
keyboard. If not, replace Signal Distribution Unit.
2.
Individual receiver/driver non-operative: Check green LED indicator on fuse
bracket in receiver/driver box. This signifies that AC power is applied by the
keyboard. If not, check shielded-twisted-pair cable between Signal Distribution
Unit and receiver/driver box. Confirm camera address setting in receiver/driver
corresponds to same camera number as selected by the keyboard. Perform
internal receiver/driver local test to verify operation of receiver/driver circuitry
and pan/tilt/zoom wiring.
3.
AutoDome series dome cameras are not operating in a variable speed fashion:
Verify CPU DIP switch 7 is selected for variable speed mode.
1.
No system alarms operative: Verify power LED indicator on Alarm Interface Unit
is lit. If not, check fuses on front of main CPU bay power supply. Verify the
Alarm LED indicator lights and the audible buzzer sounds (if enabled) only
when an 'alarm' is applied to the unit. If not, replace Alarm Interface unit.
2.
Individual cameras/monitors not responding when alarmed: Ensure desired
cameras are properly armed on the appropriate armed monitors in the system.
Verify alarming device and cable to Alarm Interface unit intact.
3.
Incorrect system alarm response: Verify that the desired alarm response mode
has been selected. Refer to the section on Select User Functions for instruc-
tions.
During the evolution of the system, there have been various CPU software versions
released. In certain troubleshooting cases, Factory Technical Support personnel
may ask for the version of the CPU. If it becomes necessary to obtain a CPU soft-
ware version number, follow the steps below:
CPUs supplied in systems sold after 1995 (having 1, 2, or 3 8-position DIP switches):
1.
Using a system keyboard, an operator with a level 1 priority can enter keyboard
User Function 23. Press the [User] key. Enter 23 using the numeric keypad, then
press the [Enter] key.
2.
The CPU version numbers will be displayed on the overlay of the monitor cur-
rently being controlled by the keyboard. Record number for future reference.
Very Old or current CPU Versions (having 1 or 2 8-position DIP switches):
1.
Remove the front panel of the main CPU bay by loosening the four corner fas-
teners.
2.
Turn OFF main AC power switch on power supply.
3.
The CPU module is located next to the power supply. Pull out CPU module from
the card cage until IC's containing white labels are visible. The white labels con-
tain copyright information and software version numbers. Record all numbers
from label for future reference.
4.
Re-install the CPU module and switch ON main AC power.
5.
Re-attach front panel.
