Compare the two non-B single-channel packages
Both packages name an MWR12 receiver. Compare the exact transmitter, its low-battery alarm and its specified battery chemistry: the MWT12 option lists alkaline cells; the MWTA12 option lists lithium cells. These are non-monitored systems with a two-wire normally open edge input. The source's transmitter NEMA 4 rating does not rate the receiver, and the similar B-suffix packages remain separate references.
