Proper FA wire for EST- 3 devices

[deestech]

I think the ducts are on the same SLC. Thanks for the good advise. We will try another loop. I'm still skeptical of the FA MC cable.

Thanks so much

I have a concern regarding DGP panels. We did not add any DGP to our new FA system, and the FA cable is a bit long. Will adding DGP solve the issue.

Are the new duct detectors (47 units) going into alarm (at random) because there is no DGP installed?

Thank you

siga-sd's are the problem. Keep swapping the bad ones out, after 6 months or so you wont have any more problems. same with mapping fault and siga2-ps detectors.

Try replacing the slc card. Had a new system we just did and it ended up being the cause. I was getting random comm faults on detectors.

I would not see the wire as an issue unless you are talking 10k feet plus

What to Do
1. SuperDuct Smoke Detectors that experienced false alarms and trouble signals caused by
excessive condensation will need to be replaced with a different smoke detector model as
indicated in the table below.
Affected Model Replacement Model
SIGA-SD SIGA-DH Intelligent Duct Smoke Detector Housing
SD-2W 6260A-CU Housing and EC30DU-3 Detector
