I bought a 2001 on ebay, and I’ve been trying to find a manual for it, but to no avail. I mostly just need a wiring diagram.
Also, do 2001’s work without coder/march time cards in it, as the panel doesn’t seem to have one. Thanks 
Also, if a picture is needed, I can link some from the auction.
Hopefully this may be of assistance. http://firealarmresources.com/simplex-4208-2001-2100/
I have some 2001-8023 information. I will PM some dropbox links to you later.
Yes, a 2001 will function without a coder or march time module. However, if the panel had one that was removed, the modifications made to make it work will have to be undone.
Pictures would be handy so I can what cards are in the panel.
I wonder, what is the Simplex part number on that horn/strobe bypass switch!
Not sure, but I will be able to tell you soon 
looks like a CUST-001 module.
Not to mention the pieces of black electrical tape covering up all those pesky trouble LEDs! “Panel looks ‘normal’ to me!” Lol
And the trouble switch set to “silenced” :lol:
