ANSI Standards: M-Series locks meet all requirements for installations in doors and frames prepared in accordance with
ANSI specifications A156.13, 2005
Metal Doors: Suitable reinforcement is required to support lock case in center of door and to prevent door from compressing
when trim is tightened. (See ANSI A115.1)
Thick Doors: Locks for non-standard door thickness may require special instructions
Lead Lining: When M-Series locks are ordered with lead lining, add 56" (3) to the width of the mortise cut-out on the lock case cover side of
installation
Electrified Locks: Provisions must be made to route low voltage wire to the lock. Attach wires to the 6" (152) pigtail of the solenoid.
Power transfer unit and low voltage wiring are not furnished
