Esl 1500

Hi I have a ESL 1500 fire alarm panel and I am about to get a lot of ESL smoke detectors. I do not know what to do with them any ideas? Also, does anyone know how to wire this thing?

I am also selling it for $2000 usd

If you’re interested in wiring & using it ask CoolSimasGuy: he’s got one & should know how to wire it.
