Transient voltage surge suppression remote supervisor module used for the modular panel system and high joule modular panel system. Use with 52000 and 57000 series TVSS panels. Simple connection via an optically isolated, two-conductor (18 to 22 twisted pair) cable input port. Suitable for surface mounting. Mounts easily with two screws. Provides remote indication warnings (repeater or annunciator) when TVSS panel failure is detected. Failure warnings from TVSS panels installed in a remotely located area (such as in a basement or electrical equipment room) may not be seen or heard. Remote Supervisor provides an acoustic beep and flashing LED whenever TVSS panel failure is detected. When this occurs a qualified electrician should be contacted to inspect the TVSS panel and follow proper panel servicing procedures. TVSS panel products are configured so that multiple panel warning signal lines may be wired in series and terminated in one Remote Supervisor. Remote Supervisor is powered from an ordinary 1-phase 120 V, 60 Hz source, self contained cord and plug. Signal wiring is Class II wire pairs.
