2 ASA-72 Hardware Manual

1 Introduction

An access control system provides a means to replace traditional key and lock systems, which

are easy to defeat because of the ease of copying of keys and use by unauthorized personnel.

With electronic access control, the exact areas a person is able to access as well as during what

time is configurable through a central control system. In addition to the power of greater control, a

historical record is maintained which is useful in the case of a system security breach or for other

purposes including calculating work time and facility use costing.

1.1 Overview

The status panel provides alarm status monitoring for up to 72 alarm zones. The ASA-72 contains

an on board processor and a serial link (RS-485) for host communication.

The ASA-72 monitors and displays alarm, trouble, and non-alarm status. It may also be

configured to display access control status and configuration information such as access granted,

access denied, duress, on-line, off-line, tamper, held-open, forced-open and auxiliary alarm.

The ASA-72 contains an audible alarm and provides front-panel switches for alarm

acknowledgement (ACK) and for LED test (TEST).
