Many times when I get calls at my home, I get a high-pitched squeal not unlike a fax tone immediately after the second ring, then the phone goes dead. Could the alarm system be causing this?
Yes, it could be the alarm. Most modern alarms have the ability to answer an incoming call from the central station (as well as make automated outgoing calls to report emergencies). The purpose of the alarm answering is to receive program changes from the dealer who may use download software to remotely program or service the alarm. Typically, the alarm control panel will be programmed to only answer a call specifically form DFT Securitys computer and does not typically interfere with regular telephone calls. It is possible that your system is either programmed to pick up after too few rings or it may have another problem. Either way, from what you describe, it sounds like the alarm is at fault. Call DFT Security to discuss how we can fix this for you.
