Audit legacy cellular communicators for sunset radio generations and plan upgrades

Steps

1. Pull an inventory of installed communicators by model/radio generation across the account base — nationwide 2G and 3G networks have already been shut down by major US carriers.
2. Cross-reference communicator models against manufacturer bulletins identifying which units are on older, retired radio generations versus already-upgraded 4G/LTE-Cat-M or equivalent technology.
3. Prioritize fire alarm and life-safety accounts first, since a non-functioning communicator there is a life-safety compliance gap, not just a monitoring inconvenience.
4. Budget and schedule technician visits for module swaps, factoring in customer notification and any code-required documentation updates after the swap.
5. Verify each upgraded communicator successfully reports test signals to the central station before closing out the account as compliant.
