Battery Backup on the 49-450 and 49-450A is accomplished with
10 "C" size NiCd or 8 "C" size alkaline batteries inside the unit.

Battery Backup on the 49-450B and 49-450C is accomplished with 
2 6V 2.5AH NiCd batteries (23-181) stored inside the panel. The
batteries are connected to the panel by a red and a black lead
and not by screw terminals.

Keypad Connections (49-535, 49-535A, and 49-537) using 6 conductor wire:

Note: When connecting multiple keypads or running keypads long distance,
      ensure that the "Key Switch NO" and "Key Switch Common" use a  
      twisted pair wire type or intermittant operation may result.
