Mircom 306b Key

MIRCOM 306b key. Used Mircom pull stations and firefighter telephone systems. 

• Key sleeve labeled as 'M'

Note: The Mircom 306b key can sometimes work in Simplex locks if pushed in firmly, but success varies and isn’t guaranteed. The Simplex B key will usually operate Mircom locks if it’s inserted almost fully and then slightly withdrawn. Both keys are available, but if you can only have one, the Simplex B is the more versatile choice. See second photo for an illustration.
