Do not go with this company if you need customer service! We have been trying to get service for a repeated alarm going off (need a new battery) for 3 months. We have been lied to on 2 occasions that someone is on their way. We have yet to see a technician. In the meantime, we have employees that are trying to work with an ear-piercing, shrill alarm. Plus, we have no idea if the system will even work in an emergency or if it will release a dangerous fire retardant without any type of warning.
