Single Source Justification Summary

This is a Single Source Justification (Simplified Acquisition) document for a spare parts procurement by the 35th Contracting Squadron at Misawa Air Base, Japan. The contracting activity seeks to procure Federal Signal spare parts for the Misawa AB Emergency Mass Notification System, including a PCBA UV+ Controller (Q2005698G), a charger/battery unit (Q8600002236), and a sealed gel battery (80-1550000/A-04). The estimated contract cost is redacted, and the purchase request/local ID number is also redacted.

The justification establishes that Federal Signal is the only brand capable of supporting the emergency notification system due to the proprietary nature of the equipment. The contracting officer determined that a single source is reasonably available in accordance with FAR 13.106-1(b)(1). Market research through FPDS-NG and Internet searches confirmed that Federal Signal maintains the standard used by various squadrons and is the incumbent system. To preclude future single-source awards, the document recommends encouraging future interoperability with other brands, moving the base to interoperable equipment, or transitioning to an alternative brand that would meet government needs while providing better value. The contracting officer, 1st Lt. AUGUSTINE E PEREZ, USAF, signed the determination on February 18, 2026.
