You can't put a price on safety - to prevent fires at home, experts recommend testing your smoke alarms at least once a month and replace the batteries at least twice a year. Hire a home service pro to ensure your smoke alarms are installed properly.
I have dealt with Safe Tech for over 20 years.
Their technicians and sales staff are knowledgeable and have always provided prompt and courteous service. I would definitely recommend safe Tech to anyone looking for a security system.
