Q. Can other sensors be integrated into the system now or at some time in the future?

A. Yes, the STU we utilize for magazine monitoring has 4 I/O (in/out) contacts. One contact is used for each door sensor, the remaining “dry” contacts can be used for any sensor capable of providing a “change of state” (e.g. moves from NC – normally closed to open, or from NO – normally open to closed). Digital sensors (e.g. PIR – passive infrared sensors) can be utilized if there digital threshold output is provided as a “trigger” signal.
