The M series was a series of sirens made by Sterling. They usually either came in 16/16 port or 8/16. They came in 2 models: The M-5 and the M-10. The M-series was produced from the 1920's up until the 1970's, when Sterling Siren and Fire Alarm was acquired by what is now Sentry Siren Incorporated.
