Introduction

1.1 General Description

Remote Alarm and Alarm/Meter (948A-40 & 948A-50)

The 948A-50 Remote Alarm/Meter continuously indicates the level of radiation at the detector site and provides a
visual and audible indication of a high radiation level on an analog meter, light, and Sonalert. The meter of the
Remote Alarm/Meter is an analog meter scale that indicates in the range of 0.1 to 10
actuated when the radiation level exceeds the high alarm set point of the Universal Digital Ratemeter. Both models
have a momentary pushbutton to silence the Sonalert. The 948A-40 and 948A-50 enclosures are Steel. The 948A-40 is
identical with the exception that it has no analog meter. Refer to Appendix A for drawings.

1.2 Application

The remote alarm/meter is an actual component of the 945 and 945A Wide Range Area Monitoring System. A typical
Wide Range Area Monitoring System consists of the following VICTOREEN instruments: a 977-series Ion Chamber
Detector, a 946A-200 Universal Digital Ratemeter (UDR), and a 948A-50 Remote Alarm/Meter or 948A-40 Remote
Alarm. When used with 977-201 detectors, refer to Loop Diagram 945-3 for interconnection information. When used
with 977-210 detectors, refer to Loop Diagram 945A-3 for interconnection information.
