Model 944-17/18, 948A, & 958A

Remote alarms are available for area and process monitors to provide a visual/audible indication of a high alarm state. Remote alarm units are also available with an analog meter scale that indicate in the range of 0 to 10⁷ CPM or various mR/h ranges. Remote alarms for process and area monitors are driven by the associated ratemeter or Model 960 Local Control Unit, which provides both the analog signal (for the meter) and the alarm signal (for the visual and the audible indication). For ion chamber area monitors, the remote alarm can be electrically driven by the digital preamplifier. The remote alarm and indicator will interface to the Model 942A Universal Digital Ratemeter and a Model 943 Series Scintillation Detector. The alarm can be located up to 1500 feet from the UDR.
