Hi, I just got intall an LC-151 sensor by my Alarm company, the setup the sensor and made some test but in the night the alarm goes on so i shut it down and next day i could turn on the alarm. Probably this sensor was not setup correctly but I wonder where can get some lectures to know more about it? Saludos
