Hello, while trying to revive an old Safewatch 3000/20P system and configure two new 5800CO detectors the keypad (6160) is not allowing me to enter any zone type from 11 - 19. I've had success with this panel and programming other devices in the past. Any ideas? Thank you

---House is wired with a Safewatch 3000en WA3001-2.5 chip. ---We are building a detached garage. ---I would like the garage and house security systems to operate independently. An example, I'm in the house doing my thing with the house security off, she comes home to a garage with the security on and it is triggered as she enters. She feels safe, disarms the alarm with a fob and unloads groceries or whatever and then rearms the garage with the fob and enters the house. To do what I want I'm imagining the easiest solution is just to leave the house security and its monitoring as it is and to add a Honeywell Lyric system to the garage and pay a nominal fee to self-monitor the garage. I understand I could probably switch out the chip in the house Safewatch 3000 and add a part and have garage wireless sensors communicate with the house control panel and maybe have a keypad in the garage. In this case, though, it's my understanding as they would be the same system I couldn't really operate them independently as I would prefer. Any thoughts or advice? Thanks!
