CAUTION: Remove all power (AC and DC) before installing or removing modules or wiring.

2.6.1CAC-4 Class A Converter Module (MS-4 only)

2.6.1.1Installation

The CAC-4 Module can be used to convert the four 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 J1 which is located at the top right of the MS-4 main circuit board.

Install the three supplied standoffs in the holes on the main circuit board as indicated in the following figure. Carefully align the connector on the CAC-4 with J1 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.
