Tane Alarm Products
1984 saw the birth of the Alarm Contact Division of Tane Services Inc. known as Tane Alarm Products. Tane uses the finest deactivated RHODIUM reeds made today to insure long life and no sticking. Our contacts have been tested to go over 400,000,000 cycles; more important, they are able to sit still for years in an unused door and operate that one critical time. Feel free to pick on our thirty plus years of reed engineering experience.
