The CS2351 and CS5351 Expander Boards
The CS2351 and CS5351are plug-on Expander Boards that provide an additional
4 inputs to the DualCom. These will trigger channels 9, 10, 11 and 12.
Note that the DualCom GPRS uses channels 13, 14, 15 and 16 to report path
and polling faults to the ARC, thus only 4 extra inputs (9 to 12) can be used on
security installations.
The CS2351 is for use with 12 volt alarm systems only.
The CS5351 may be used with alarm systems supplied up to 30 volts.
