I used to have ADT and it was such a breeze to set the alarm to HOME or AWAY. You just need to hold the button down for 3 seconds. If you’re in the house, why do you need a passcode to SET an alarm? Passcode should only be used to deactivate.
For example, someone (guest, child) is staying in the house. They cannot remember the passcode but either need to leave or need to stay and be safe inside. They should not need a passcode for this.
Please take the hassle out of setting the alarm. The easier, the safer, the better.
