WebThe NASA Standard Initiator (NSI) is a pyrotechnic device used to set off other pyrotechnic devices. It is the central multi-purpose component of a modular system of detonating cords, ... (NSI) was developed from the Single-Bridgewire Apollo Standard Initiator (SBASI) which was itself based on the Apollo Standard Initiator (ASI). ... WebNo-fire is defined as the maximum electric stimulus which can be applied for a specific time to a bridgewire without firing the initiator. The typical no-fire design requirement is a one (1) Ampere minimum with an associated one (1) Watt minimum applied to the initiator’s bridgewire circuit for a duration of five (5) minutes, and which does not cause the … british 0-4-0 tank engine
