Re: ansel system
An Aunsul system is the "generic " name for a fire suppression system designed for use in food service exhaust hoods. You may best recognize the heads that you may see poking down over the grille at your local fast food restaurant's kitchen. The systems usually have a mechanical trigger that employs eutectic, [melting at a specific temperature] links, as well as manual "pull-stations". The "control" cabinets usually have relays or dry contacts for interfacing with various shutdowns, and alarm triggers. Ansul is the name of the fire suppression company that popularized this system.
