Hi all, I have a dry contact wired up to my EA5 as per the manual on the +12 and SIG terminal on Contact 1 on the EA5 terminal block. The contact type is one of those that is typically used by alarm systems on doors and windows (uses a magnetic connection). It is on my front gate and is a simple dry contact that shows the gate open or closed. This has worked really well for over 4 years. On Gate open (contact > open) I send a notification via 4sight to notify me the gate is open with a snapshot of the gate camera. Last two weeks it’s been going nuts. Random notifications and false alarms that the gate is open through notifications. So this is where the journey that is driving me nuts started. This is what I have done to trouble shoot: 1. Checked that the contact is making the right contact and the gate isn’t bent or too far away from the contact. There is less than 1mm between the two parts of the dry contact, no play on the gate. 2. Changed out the dry contact (just to make 100% sure) at the gate with the same make/model - same issue. 3. Because 2 didn’t work - took the wire out the terminal at the EA5 on +12 & SIG and cleaned it up stripped some new wire and reinserted - Same issue. 4. Because 3 didn’t work - Pulled a new wire (over 40M) incase there was some sort of breakage for some reason in the wire between the dry contact and the terminal on the EA5 - same issue. 5. Because the physical connection side hasn’t worked - I have even added a 10 second delay on the programming of electronic gate > Open, incase its some sort of movement on the dry contact, then it checks gain to see if the gate is open > delays another 10 seconds before doing one more if open check to send me a notification - I keep getting random notifications,. So what happens with the notifications - it can go the whole day without notifications then randomly (and I am starting to notice a pattern of late at night say 10pm on wards) I get about 40 notifications of gate open with a snapshot (which shows gate was never actually open). Not sure what else to check or if I have missed some updated setting on this contact driver to make it more/less sensitive? So on such a simple thing a bit stumped here…. willing to try any suggestions. I also have a C4-Z2IO almost in the mood to take the dry contact that is connected to the EA5 Terminal block out and try it on the C4-Z2IO incase its something gone wrong on the EA5 - but surely it cant be a dry contact is like one of the dumbest things
