BEWARE READ BEFORE PURCHASE, wish we knew!!!! This will be the fifth defective fire alarm. We get false alarms all the time. We have had the fire department here wasting their time & money all due to false alarms. We have been called back home by false alarms, when even being in the hospital thinking, omg, our dogs, but no fire, just another faulty piece equipment. Five times already. Its now 3:30 a.m. and we had another false alarm. They refuse to refund us for equipment. AND They refuse to cancel our contract without charging us $479.00 We will see you in COURT!!
