Communications Dead on DSC PC3000

Just switched to a new Alarm Monitoring company last Monday. On the Tech call we got everything working but the wired in Smoke/Heat Detector (ESL 445CT). During the call the tech had me short across the resistor on the ESL 445CT that jumps terminal 3 and 4. We did this 3 times and although the system dialed into the Alarm Station, no Fire signal received. Tech then stopped, was going to consult his peers. Another tech called on Tuesday and we did the same test twice, however we let the alarm go off for 30 seconds. (Installation manual states that Fire alarm must go off for 30 seconds before signal transmission.) However this time the system didn’t even dial into the Alarm Station, but did lock my system at no phone line. So, since last Tuesday, once I arm my system, my phone line goes dead. After disarm, system will release phone line (dial tone back) after 5 minutes. Trouble code is ‘Unsuccessful communication attempt with monitoring station.’

Today, at 12pm EDT, I will have a call with a senior tech from the monitoring company. I would welcome any thoughts as to what the original test might have done. We reset the system twice by unplugging from power and battery (once for 6 hours) with no effect last week. That is all we did.

Any and all thoughts welcomed and appreciated! Thanks!

PC3000 is a solid panel.

You really need to do some troubleshooting. Specifically, listening in on the call to see if a call is being made and what happens. A skilled tech can identify what is occurring by listening to the call progress and the different tones. Programming may need to be checked. That 3000 can only report 4+2 format which is pretty universal but requires programming for each event that is reported.

That’s what I was thinking. Probably wrong event code is programmed
