Which variant do I need?

If your network…	Order	Why
Runs ALERT2 (or this is a new network)	5391/A2	Current NHWC standard
Is an existing legacy ALERT system	5391	Matches your current receivers; upgradeable later
Needs remote polling or control	5891/A2	Same station on the two-way 50388 SCADA platform — 5891 details →
