Can I bypass individual zones without disarming the entire system?
No, the system must be disarmed before you can bypass zones. After bypassing the desired zones, you then arm the system as usual. Bypassed zones are automatically unbypassed when the system is disarmed, and the system will not allow fire zones to be bypassed. (Page 22)
