The Home Security Store Informative - Home Security Devices
This store sold me a promax 45 alarm systems and the remote transmiters fail regulary like every year. And you must have thes to make the system work. The are plastic and fail to transmit causing false alarms. To replace each transmiter is 40.00. Plan on spending this money again every spring. I have ask to contact the mfg. but they will not provide the customer help line for their product. If the transmiters are ever upgraded to last this will be a good product. But for now buyer beware do buy here.
They will also no give a discount on new retransmitters I must spend 300 dollar each spring and worry when the will break down send a false alarm.
