I have a site with quite a few system sensor sounder bases and when we hook up slc the panel says there is a short.

When metering the circuit we found a read of 310k.

We chased that down to an area of 10 sounder bases.

We pulled new wire in this area and started slowly re wiring the sounder bases back up, we get about 5 bases in and we get a reading of 300k and it climbs up to about 650k and then it seems to discharge and go down to 1.2m

If we re do this "experiment " and remove the last device when the meter shows 300k. The meter still shows 300k and keeps climbing then drops to 1.2m

I have 0 clue what is going on any input would be appreciated.

Posting to see if anyone has encountered a silent knight 6820, that the mics do not pass the audio through.

When the system is in alarm, and you press the mic button the fire message cuts and panel stops beeping but i can not speak through the mic.

Mic gain is set to 5 and we tried bumping it up.

Any ideas would be appreciated.

Thank you
