05-437 Primalert 35 area radiation monitor

When the preset level is exceeded, personnel are alerted by bright flashing red lights (visible over a 180° field) and a loud intermittent audio signal. The alarms stop automatically when the radiation level falls below the preset value. A front-panel switch permits the selection of both the visible and audible alarms or just the visible alarm. Fail-safe operation is assured by a light which continuously indicates background radiation and provides visual proof that the unit is functioning. The monitor will not jam or show false readings in high radiation fields. The Primalert 35 contains an energy-compensated GM detector, and features a convenient, automatic alarm reset. A mounting bracket and a 110 volt AC adapter/power converter are also included. The optional Primalarm Remote Alarm provides the same audible and visible signals as the Primalert 35, up to 100 feet from the monitor.
