i had one of theses tatian alarm system installed augest 9 2011. 2 hrs after it was installed it started beeping none stopand when u pushed the disarm button nothing happend still kept peeping i went and tracted down the kid who installed the system and told him whats happening. he said he will be right back to look at it. WELL 7 months later a repair person showed up and installed a new battery then said everything is ok now NOT. 2 days after he left it started beeping at 3 am in the morning none stop untill the battery went dead. so i contacted titan and asked to have the system removed because enough is enough . now they want over 2000$$ to remove it
beware
