The Blurb:

The CM704B zone expansion module allows quick and easy installation of addition physical inputs to the intrusion control panel. Being LAN based the CM704B may be co-located with the intrusion control panel or remotely located.

When used in conjunction with a Solution 144 or 6000, the CM704B allows an additional 8 zones, or 16 zones with the zone doubling. You can have multiple CM704B units connected to the LAN which allows up to 144 zones. A 4 - core cable is all that is needed to relay data back to the main alarm panel which greatly simplifes cabling.
