Cardea Wireless Locking System


Cardea Wireless Locking System System installation in a bank office

This case study outlines phase one of a Cardea Wireless Locking System installation in a metropolitan bank office. Customer goals and Idesco’s evaluation and solutions are accompanied by a site floor plan displaying egress, access control points and product placement locations. By conclusion of phase two, installation had expanded to two Idesco Controller Units and 17 Cardea readers for two distinct sites (second building floor plan not included), all programmed to interrogate over 1000 tags.

Assessment of Customer Requirements

Interview with customer established scope and nature of their lock management requirements. Customer desired a simple yet utterly secure deployment solution with minimal need for administrative oversight, seamless integration with existing population of over 1000 tags and ability to adapt to future structural changes.

Customer’s phase one site comprised a fairly condensed cluster of over 17 entrances with 12 private offices, four semi-private rooms (e.g. meeting room, kitchen, etc.) radiating roughly out from a shared lobby/foyer. Outer walls were uniform concrete while interior dividing walls were primarily a mix of 2.5 meter high wood and glass partition walls with a small percentage of solid concrete or full-height glass walls.

Visual assessment of customer’s security requirements confirmed all requested lock control points would easily fall within effective broadcast range of a single, centralized controller unit. Each doorway possessed satisfactory reader mounting sites (wood or concrete) for convenient tag swipe positioning.

Controller-reader communication tests conducted in proximity to available power sources determined optimal siting of the Idesco Controller Unit per customer’s preferences and a necessity for ensuring robust communication with all readers.

Solution Development

Customer’s universal access tag rule enabled access by any existing tag through 17 doors for which the customer requested readers by end of phase 2. Customer’s tags were determined to possess a shorter data standard. Cardea readers’ software was updated to ensure compatability to customer’s standard. A new database was populated with customer’s tag data and imported into Idesco Controller Unit. Lastly, a tool was provided to customer for creating future additional tag databases.

Features of Installation

The completed system deployed at both sites was designed to readily accommodate future changes to building structure. Two Idesco Controller Units, programmed to function independently (without event logging) were placed in central locations at both sites, assuring robust communication with all 17 readers.

Readers were installed proximal to 17 doors at bank office’s two sites. FET outputs were connected to time relays and magnetic locks. Communication between Idesco Controller Units and all 17 doors successfully tested against a sample population of customer’s tags. Installation was evaluated a success by both customer and installer.

Installer at bank premises: “Installation was quick – we never needed Idesco’s help. In fact, we’ve never had such an easy job before.”
