Introduction

The CERBERUS PYROTRONICS
Model MXL Control Panel is an ad-
vanced fire protection and alarm
control panel that provides superior fire
protection, voice evacuation, and
multiplexed alarm reporting.
The basic MXL Control Panel can
monitor up to two analog loops, each
containing up to 60 CERBERUS
PYROTRONICS intelligent devices.
Through the addition of a MOM-4 card
cage, the System can be expanded.
With the addition of PSR-1 power
supplies, the System can be expanded
to as many as 34 analog loops.
The MXL Control Panel can control a
wide variety of System outputs, such
as conventional Form C relay contacts,
solid state outputs, supervised outputs
to control alarm notification appliances,
municipal tie outputs, and leased line
outputs.
The MXL Control Panel can process
logical decisions based on the status
of initiating devices. The System can
respond with customer-specified
sequences of output circuit operation.
The System continuously checks all
software and hardware for proper
operation. It continuously checks all
System memory components, control
panel electronic hardware, and the
System program. A hardwire watch-
dog circuit is provided to ensure that
System programs are functioning
properly. If a problem develops with
the program or processor, the watch-
dog circuit places the System into a
trouble condition and resets it.
To ensure reliable operation, the MXL
System is composed of independent
modules, each with its own micro-
processor. If the main panels central
processing unit stops, these modules,
operating in degrade, still annunciate
any alarm or trouble through common
lines called Any Alarm and Any
Trouble. All of the modules commu-
nicate with the MXL Panel through a
serial communications system.
All modules are continuously super-
vised for their presence and
for proper operation. Problems are
shown on the display to aid in servic-
ing and troubleshooting (See Using
the Menu in Chapter 3 - Operation).
The MXL System is designed so that
fire alarm operation has first priority
over all other modes of operation. If
the System loses battery and commer-
cial power, it automatically goes
through an initialization routine when
power returns.
