I am working on a very old fire alarm system that uses an EST LSS1 panel. The panel itself is still functional but there are some EOL's missing etc. and even though I want to do a full upgrade and bring the system up to code, the customer doesn't want to spend the $, so repair is the only option. Does anyone know where I can get documentation for this panel? Also is this panel comparable to the LSS4?
Thanks in advance!
