INTRODUCTION
The B.A.S.I.S. V Service Manual contains essential
information to help you maintain your B.A.S.I.S. V
Locks and EX Series Exit Hardware Trim.
Throughout this manual, the term standard
B.A.S.I.S. V Locks is used to refer to 35HBV Mortise
Locks and 93KBV–95KBV Cylindrical Locks.
The term EX Series Exit Hardware Trim refers to
EXBV Exit Hardware Trim. B.A.S.I.S. EX Series Exit
Hardware Trim is available for use with the following
types of exit devices manufactured by Precision
Hardware (1000 Series and 2000 Series) and Von
Duprin (98/99 Series):
■rim
■mortise
■surface vertical rod
■concealed vertical rod.
Standard B.A.S.I.S. V Locks and EX Series Exit
Hardware Trim are available with the following types
of readers:
■magnetic stripe card readers
■smart card readers
■dual validation (magnetic stripe card/keypad)
readers
■Motorola and HID proximity card readers.
