Abstract: In one aspect, the invention provides an access panel that comprises one or more access control boards, each of which provide at least an interface for controlling access to one or more building entry points or zones (via associated sensors) and for monitoring intrusion prevention devices. The access panel includes at least one connector that provides communications coupling between at least one of the control boards and the aforementioned sensors or intrusion prevention devices (e.g., detectors, electrified locks, etc.). That connector permits that coupling without requiring that a field technician, or other person installing the panel at a site, pass wire through the enclosure in order to establish that communications coupling.
