1.INTRODUCTION

1.1.SCOPE AND PURPOSE OF MANUAL

This manual is designed to enable operating and service personnel to properly operate and care for the AM-255. Since applications are necessarily site-specific, operation procedures are given in general terms. Service and repair are covered to the board level. Anything more complex than this requires that the instrument or assembly be returned to TSA.

1.2. GENERAL DESCRIPTION

The TSA Model AM-255 Alarm Monitor is a self-contained unit designed for use with TSA’s personnel and vehicle portal monitors. The AM-255 provides both audible and visual alarm indication for radiation level, high and low background, low power and tamper conditions. In addition, output relays are provided to integrate the AM-255 into existing alarm systems.

The AM-255 is a dual input instrument, which will monitor two sets of pillars, or two master pillars. It has two complete sets of front panel lamps, as well as two input and two output connectors. The two systems are totally independent.

1.3. SAFETY PRECAUTIONS

WARNINGS:

The AM-255 uses 90 to 250Vac for the battery charger. Service should only be performed by qualified technical personnel.

The maximum voltage and current being switched by the relays must not exceed 0.6 amp at 120Vac.

CAUTIONS:

As with any sensitive electronic instrument, the AM-255 should not be dropped or subjected to severe mechanical shock.
