Edwards G1M-RM — remote-mount Genesis Signal Master for strobe synchronization and independent horn control. Genesis strobes self-synchronize, but the Signal Master holds a circuit to one flash per second indefinitely and lets horns be silenced while strobes keep flashing on the same two wires. The -RM suffix is the ordering decision: it mounts in its own one-gang box, a BPS cabinet, or a SIGA-MP plate, while the plain G1M snaps onto the back of the first appliance. Output rating 3 A max — the G1M piggyback version is rated 2 A 16 to 33 Vdc, 16 to 33 Vfwr; current draw 33 mA One flash per second within 10 ms indefinitely 20 Ω max resistance between two appliances in the same viewing area Mounts in a 2-1/2" (64 mm) deep single-gang box 12 to 18 AWG; UL 1971, UL 464, ULC S525 One Signal Master per circuit; it synchronizes only appliances wired downstream of it. The strobe circuit needs a dedicated NAC that stays continuous in alarm, and horn control works with horn-strobes only.
