Controls a single door through a single reader input. Allows any magnetically encoded card programmed with a Start Sentinel (SS, BH) in the first position access into the vestibule.  A potentiometer located on the MSLR1 control board may be adjusted to select the number of seconds the door will be unlocked after a valid card is swiped.  Optionally, the MSLR1 may be configured/populated with up to 3 numeric switches which in turn allow the system to check for up to 3 specific characters following the SS.  However, this optional configuration is rarely used because most banks encourage the use of their own ATM’s by holders of non-member ATM cards.
