Sentry 8501 Portal Monitor

A built-in red strobe light (with a visible range of up to ½ mile) and an audio alarm are activated when the alarm trigger threshold is exceeded. This feature may be disabled via a menu selection. In either case, a report is recorded in an event log on the hard drive. The logged incident report may be viewed at anytime at the monitor. The log contains specific information for each event: Time and date, count levels, threshold setting, multi-channel analyzer spectrum, isotope identity and a photograph(s) of the violator. This log may be wirelessly transmitted via LAN to remote processors, such as a cell phone, PDA, computer, etc. with internet capabilities. 

Available modes of operation include a continuous radiation monitor, a “sleeping watchdog” monitor (becomes active only upon a violation), and a latching monitor that requires a supervisor to reset the monitor after an event occurs. In each case, an event is recorded in the event log.

The NEMA security enclosure provides a tamperproof, water resistant and lockable enclosed space for the system electronics and internal detector. Password protection prevents unauthorized access to the system software.

Once initial set-up is complete, the system will operate without operator intervention. The set-up procedure requires no computer skill and is user friendly. When the power is turned on, a diagnostic routine is initiated, a background reading is acquired and the monitor mode begins to cycle displaying counting information at 1 second intervals.
