Download Census Model 4821: User manual

System Overview
Congratulations! You’ve just purchased the Model
4821, a state of the art electronic access control
system, designed to provide you with many years of
round-the-clock protection.
Your Model 4821 system has been custom
programmed and installed using the options and
features that most closely meet your needs. If you
have any questions about your system, talk to your
installation company representative.
This manual provides basic instructions for daily
system operation. For your convenience, separate
operating instructions are included for single-area
and multi-area configurations (your installer will tell
you which type of system you have).
Some operating procedures are marked with a box
( ) to indicate that the feature is optional. You or
your installer can use these boxes to show which
features have been included with your system.
Knowing how to fully operate your system will
enable you to maintain the highest degree of security
and prevent false alarms.
…
Keep this manual in a secure place for future
reference. If the instructions in this manual differ
from what your installation company representative
has told you, follow your representative’s
instructions.
Your Model 4821 security system can protect your
building using sensing devices such as door contact
switches and motion detectors. These devices
provide 24-hour electronic surveillance detection
and reporting.
The 4821 can monitor up to 400 separate zones,
which are simply protected areas in your building
such as doors and windows. Through touchpads and
audible signals, you can quickly identify which part
of your system is in alarm. You can also disarm
selected areas in your building, while other areas are
still armed.
Touchpads are normally installed in main office
areas and building entries for convenient operation.
Programmable in many ways, they provide an
extremely high degree of tamper-resistant security.
