To star, I have tried do wire the unit as the manual tell you. I have used an enforcer 12v unit to imput voltage in the red and black but then i have the problem that the normaly close sensors outpu voltage, and the unit dows not power on. so I am scared to wire the unit into the pgm zones in the alarm system because i do not know if this is normal. Also i do not know how to close the sensors so the unit stop reporting alarms. beacuse i have powerd it on with the optional dc imput or with the 9v ac.
