Trouble
When a trouble condition occurs (such as cut wiring for a point or AC power fails), the
sounder beeps every 10 seconds. The Trouble LED lights and the LCD shows the trouble
condition. When you back out of the detailed screen when the [4/<] key is pressed the group
is entered and shows TROUBLE (XXX). The system can diagnose and show a variety of trouble
conditions, including those affecting the input points, NAC circuits, power, battery, system
grounding, and internal operations of the fire control panel. Notify your installing company
immediately if the system trouble message appears.
Press the [Acknowledge] key to silence the system trouble beep.
Fire Silence/Reset
Danger!
Fire Alarm!
During a fire alarm, exit from the premises immediately. Do not enter the premises unless ac-
companied by the appropriate emergency services' personnel, or until they have given the OK
to enter.
DANGER!
When it is determined that there is no fire, you can silence the horns or bells to allow more
investigation of the devices that initiated the alarm, or you can reset the system to return it to
normal operation.

Notice!
Before resetting fire alarms
Before using the [Reset] key, determine which smoke detector sounded the alarm so that the
monitoring company can check that the system is operating correctly. If the control panel is
being used as an addressable control panel, use the [History] key to determine which address
is in alarm.
NOTICE!
If the system is configured to allow alarm silencing, the [Silence] key turns off the horns or
bells, but does not reset the alarm status and does not return the activated input to normal
service. Detectors that were activated stay in alarm and can be checked (usually by observing
an LED on the device) to see which detector caused the alarm. When the detectors causing
the alarm are identified, reset the system to return it to normal service.
The [Reset] key clears the system alarm status, and briefly turns off power to the detectors to
reset them. This command is required after any fire alarm affecting a point programmed for
latching operation (which is the normal configuration). This operation is also required to reset
Class A, Style 6 multiplex (SLC) wiring fault troubles.
The software automatically supervises the system software for proper operation. If the system
fails, a CPU FAULT message appears, and the nature of the failure can be optionally recorded
in the history buffer. To enable history buffer recording for CPU faults, program Output Zone
D of onboard Relay 2 to Zone 51 (unused). The history buffer message, if enabled, shows
CPUFLTxxx, where xxx is an error code. If the display shows CPU FAULT, contact Bosch
Security Systems, Inc. Technical Support and report the history buffer code along with a
description of the operations that caused the fault. Unusual conditions during programming
and debugging operations can result in a CPUFLT message in the history buffer. If, this occurs
when the control panel is in service, report it to Technical Service.
