Wiring bell box INT500s to scantronic panel

As below ….there isn’t much room in those contacts and things can get shorted…
I would never use this type …either a multi version with built in resistors or elmdene QST -RD contacts
Just wired it as you’ve drawn and tbe only options on the key panel that turn green once i set it are Log, security and tamper return…. The rest just stay red……. Any ideas ?
