hello im new here. I have an Ademco Vista 20p alarm panel and I would like to add the module for arming, disarming, checking my alarm via telephone. I really want to be able to disarm the alarm from my cell phone as i drive up in my car. its hard to get to the keypad sometimes with kids groceries etc.. I would also like to be able to disarm and arm the panel on days when i expect serice or deliveries to the house.

you need the Honeywell 4286 VISTA Interactive Phone Module (VIP)
