17.1 Introduction

The PC4020CF is a UL/ULC Listed panel for [1] Central
and Remote Station Fire Monitoring [2] Local and Central
Station Burglary Alarm Monitoring and [3] Access Control
(in conjunction with PC4820). When used as a fire panel, all
fire functions must be configured to take priority over Bur-
glary, Access Control and other auxiliary functions.
The PC4020CF has a number of system functions estab-
lished as default values. These functions must be main-
tained to ensure the Life-Safety integrity of the installation
meets all applicable codes and standards.
To ensure an appropriate installation, all applicable NFPA,
UL and local codes and standards should be reviewed.
Local AHJ (Authority Having Jurisdiction) should also be
consulted prior to installation to determine specific local
requirements for a fire alarm installation.
Information in this manual is intended to describe the fire
functionality of the equipment. Further information on the
overall system is contained in the companion manuals for
this product and must be consulted for a full understanding
of operation, installation and programming.
This manual lists a number of alarm initiating and alarm
notification devices for use with this equipment. Use of
devices other than those listed herein must be carefully
evaluated for compatibility. 2-wire smoke detectors other
than those listed in this manual cannot be used without
voiding the listing status of the equipment.
Remote downloading of a fire panel, once it has been put
into operation and is protecting a premises, is severely lim-
ited. See the Upload/Download section of this manual for
information on this topic.
