Before You Install or Replace One

• Confirm exact model number on the communicator label matches the install manual.

• Verify host panel family — Keybus PowerSeries, Neo Corbus, MAXSYS Combus, IMPASSA integrated, or universal dialer-capture are not interchangeable.

• Confirm monitoring receiver and account accept this communicator format (Contact ID, SIA, IP, cellular).

• Check carrier/network generation (3G sunset, LTE band, Ethernet path) for your region.

• Add communicator current draw to panel battery standby calculation where the module loads from panel bus power.

Sur-Gard System II IP receiver (central station)

This is a central-station receiver, not a premises communicator. Faults appear in receiver software, not panel [*, 2].

Panel FTC and alt-comms troubles apply to the host communicator, not this accessory — see the communicator listing for full trouble tables.
