2.7.1 CAC-5X Class A Converter Module
Installation
The CAC-5X Module can be used to convert five Style B (Class B) Initiating Device Circuits to
Style D (Class A) and the two Style Y (Class B) Notification Appliance Circuits to Style Z (Class
A). The module plugs into connector J2 which is located at the top left of the MS-5UD and MS-
10UD main circuit board and J7 which is located at the top center of the MS-10UD. Note that two
CAC-5X modules are required to convert all NACs and IDCs on the MS-10UD to Class A circuits.
To install the CAC-5X in the MS-5UD or MS-10UD, remove the two main circuit board mounting
screws referenced in the following illustration and replace with the two supplied male/female
standoffs in the locations indicated in the following figure. Carefully align the connector on the
CAC-5X with J2 on the FACP main circuit board and press the module securely into place. Make
certain the pins are properly aligned to prevent bending or breaking of any connector pins. Secure
the CAC-5X to the standoffs with the screws that were just removed.
To install the second CAC-5X on J7 of the MS-10UD, remove the main circuit board mounting
screw referenced in the following illustration and replace with the supplied male/female standoff.
Insert the supplied plastic standoff in the location indicated in the following illustration. Carefully
align the connector on the CAC-5X with J7 and press the module securely into place. Make certain
the pins are properly aligned to prevent bending or breaking of any connector pins. Secure the
CAC-5X to the metal standoff with the screw that was just removed.
