As the law enforcement and security arm of the U.S. Department of State (DOS), the Bureau of Diplomatic Security (DS) is responsible for providing a safe and secure environment for the conduct of U.S. foreign policy. The Security Technology (ST) directorate supports the DS mission through the application and use of appropriate technical security countermeasures. In support of these responsibilities, DS uses a Security Intercom System (SIS). The SIS is a stand-alone system that provides audible communication for security personnel. Its equipment typically assists in communications between guard personnel, other employees, and entry verification for visitors to DOS facilities. DS is seeking commercial off-the-shelf (COTS) products for this application. While potential vendors may suggest an item that is a modification of an existing product, the requirement of any future procurement will be a COTS product that is available for sale to the U.S. Government or a U.S. Government contractor or sub-contractor, in single-piece quantities. The Technology Development Branch (DS/ST/FSE/TDB) identifies, evaluates, approves, documents, and provides technical support for all Technical Security Systems (TSSs) used by the DOS at overseas facilities through a structured, validated process. TDB also provides subject matter expertise to support TSSs that are deployed in the field. OBJECTIVE If a requirement cannot be met in full, the respondent shall state to what extent a particular requirement can be met. Requirement vs target system capability definition: A “Requirement” must be met if it fits within the technical solution being proposed. A “Target System Capability” is a desired feature that would be preferable to meet but is not mandatory. RFI Deliverables All respondents are requested to provide detailed information on available systems, to include a detailed response to the requirements matrix. Respondents should state which requirements are met and which are not, technical and physical specifications of the proposed system, images of the proposed system, maturity of the technology, impact to existing infrastructure, details of current installations, and a cost rough order of scalable magnitude for a system. At this time, there is no requirement for a facility security clearance or for cleared staff under the National Industrial Security Program. However, if a respondent participates in the National Industrial Security Program and has facility and personnel clearances, that information should be provided in the response. The company must have a robust technical support group to provide user, installation, and repair documentation; technical and software updates/revisions; and training as may be needed by the U.S. Government.
