The Department of Defense, through the Defense Logistics Agency (DLA) in Mechanicsburg, Pennsylvania, is planning to issue a presolicitation for a five-year Indefinite Delivery Indefinite Quantity (IDIQ) contract for multiple National Stock Numbers (NSNs) related to miscellaneous alarm, signal, and security detection systems. The procurement includes specific items such as detector supports, PSMC assemblies, display assemblies, control assemblies, and switch assemblies, which are critical for military operations and equipment functionality. The government intends to negotiate with only one source due to the lack of available data for competitive procurement, and interested parties are encouraged to express their interest and capabilities within 45 days of this notice. For further inquiries, Sean McDonnell can be contacted via email at sean.mcdonnell@dla.mil.
