Please note: This is a Sole Source Notification. Peifer Security Solutions. The District 4 TSM&O program requires the purchase of 201 additional Cyberlock cylinders in support of the completion of the I-95 3A1 project. These devices secure the roadside cabinets that house CCTV devices, network and camera equipment for use in the TSM&O daily operations. From the estimations on the plans, there are 96+ cabinets. Each cabinet requires two cylinders (front/back). There are other cabinets located above/below the existing cabinets that are not easily identifiable on the plans and have been estimated to be an additional 8 Cyberlocks. This brings the total to 200. The lock cylinder for the hub building is a different model from the standard roadside cabinets. This brings the total to approximately 201 and should be sufficient to complete the project.
