Phone System
I do not have an alarm service yet and was doing some research to see if there were any issues/complaints about the alarm company. I want to add, that I worked for a security company for 14 years as a service technician. The way an alarm system works is a sensor connected to the main control panel triggers an alarm event when armed. This in turn, activates the dialer inside the control panel. The dialer does a couple of things then. 1 – The dailer relay which is a dry contact NO VOLTAGE what so ever, changes position/toggles to check for dial tone. When the control panel senses the dial tone, it then dials – hence the name – a preprogrammed number, just like a redial on your phone. The monitoring center is then called, again just like your phone at your house. Data is normally exchanged between the Control Panel and the Monitoring Center and then the Control Panel hangs up. The more likely cause is that the phone line probably took a surge that back fed the Control Panel, fused the relay shut and continued to the next device, the modem. This guy probably doesn’t realize this but the alarm probably took the brunt of the surge and slowed it down. He is lucky that all his phones in the house were not damaged. You see in order for the alarm to have priority over other phones in your house, it is usually the first in line if installed properly. In 14 years, I have seen my share of cooked phone lines and equipment. NEVER was it the cause of the alarm system. IT IS A LOW VOLTAGE SYSTEM! It operates in most cases at 12 volts DC and pulls realitively no noticeable current unless the siren is sounding during an alarm. The a/c transformer is usually 12-18VAC. The same as a cordless phone. Come on you Thomas Edison want to be – Don’t talk about things you don’t understand.
