Are you referring to the Map Fault issues? or just other false alarms?
My client has the same Map Fault issues (if the loop contains one or more SIGA2-PS) and hasn't been resolved to date.

We did a specific troubleshooting by removing the SIGA2-PS (only) and replacing them with the SIGA-PD, it disappears.

Siga2-PS seriously causing problematic map faults and dirty head issue. Until today UTC can provide me a solution to solve this issue until our internal team replace the detector with old model Siga- PS and some with new Siga-PD to clear the map faults. The loop cannot be mixed with Siga2-Ps otherwise you will create the loop with with map faults problem even after re-Programe. So far i haven’t seen any product recall of siga2-Ps from Edwards@UTC but they already replace the model to Siga-PD? Wonder why Siga2-Ps just a short time in the marketplace?

Update: 4-20-2020
has not had a false alarm since I tied the shields through

The site I had a problem with is using shielded cable on the SLC.
the shields were not tied through at the devices.
I wired the shield through most the devices about two years ago, no false alarms since.

IS ANYONE ELSE HAVING FALSE ALARM PROBLEMS WITH THE SIGA2-PS?
PLEASE POST

Siga2-PS Prone to False Alarms

I have a site that is using Siga2-ps that is having multiple false alarms.
it was driving me crazy until I spoke to a friend.
He said he is having the same problem with the siga2-ps devices.
his EST company rep. gave he siga-PD to replace the siga2-ps

the Siga2-ps needs to be RE-CALLED

Please add your experiences to this post.

Once a Siga2-ps false alarms it needs to be replaced, IT IS NOW BAD.
do not wait for a second or third false alarm from that device
