Sentry Custom Security is proud to announce the upgrade of old 3M 3500 library systems at the Doherty Library at the University of St. Thomas. The new Sentry RT-Controllers will save the library approximately $20,000 compared with buying completely new systems.

The RT-Controller is an upgrade for 3M 3500 and 3900 systems, as well as the Sentry WAM & MM systems, that can make old systems new again. By simply replacing the electronics with our RT Controller, your security gates are alive again with better tag detection and a remote tuning feature to perform system diagnostics, and adjustments via the internet.

The Sentry RT Controller has an optional built-in patron counter with LibraryAssist™ software that enables librarians to access detailed patron count reports using a local area network connection.

Electronic outputs add further security options, such as an alarm signal to trigger a video recorder. 

Sentry EAS equipment is manufactured in the USA.
