The fob has a maximum operating range of 75’.
NOTE:
When the 75 Function is in Normal Mode, it operates as a standard
classroom lock. Construction Access, Manual Lock Programming, and Proximity Credential
functions all operate the same as they do for a standard classroom/storeroom lock; however,
when the 75 Function is in Lockdown Mode, only a pass-through function may gain temporary
access. In this state, any other credential function makes the Schlage button blink red
(12 times) and the door will not unlock.
