The BPR-S proximity reader is a complete surface mount reader based on the Mifare 13.56 MHz tag technology with up to 1000 fob users. The validating and voiding of users' key fobs is achieved with a shadow fob system offering Bell Custom Security Coding. The reader can output to both fail secure and fail-safe lock devices and have an input from an exit button. A single LED in green, red and blue gives a visual indication of the operational state e.g. green light for valid fob and lock active.
