Both Artex ME406 and Kannad 406AF-Compact include mounting rack provisions for upgrading from the Narco ELT10. Kannad offers a 2-wire switch option (RC-102) as an easy upgrade from the Narco ELT10.
As of April 2012, Artex has not released a similar switch. Please Note, the existing 121 MHz ELT must be replaced by a 406 MHz model.
