Secondary Alarm Board Upgrade Kit 8620-323
Overview
MC5600-BC upgrade kit 8620-323 is for use with the MC5600-C Series controller.
This kit, when used along with kit 8620-321, will convert the MC5600-C
controller into an MC5600-BC (see Table 1).
The 8620-323 kit consists of:
- 8612-069 Secondary Alarm Board
- 11″ Cable
- Standoff Purse Lock Wire Tie
- Phillips Head Screws (4)
- Upgrade Identification Label
- 7960-898 Supplemental Instructions
The MC5600-C controller includes features for remote communication and alarming using the Ethernet port located on the back of the display. The 8620-323
upgrade kit allows the user to expand the alarming capability of the
controller by adding additional NO/NC alarm dry contacts. See the latest
version of MC5000 Series Installation and Operation Instructions 2100746 for
the full list of alarms located on the secondary alarm board.
This upgrade kit, along with kits 8620-321 and/or 8620-322, can also be used
to convert an MC5300-C or MC5300-BC controller into an MC5600-BC (see Table
1).

IMPORTANT: Bard recommends the use of personal grounding straps to prevent static electricity shorts to electronic controls.
