Description

Access to the enclosure is requested when the user swipes his access card onto the card reader. The system communicates to the back office where the back end software verifies whether the user is authorised to access the enclosure at the requested time. If yes, the device emits a short beep and the front panel door unlock allowing access. If access is denied, then a long beep is emitted and access is denied. The rear door is unlocked via a push button from the front which releases the rear lock if and only if the user has authorisation for rear access.

All events are logged onto the back end software and on the memory of the device. The memory operates on First In First Out (FIFO) queue and old data are replaced by the latest access information. If any of the doors remain open the door switches will report the event since the switches are wired in series.
