So I've just installed a Pyronix Euro 76 alarm panel (Confiqured and running the system in the DEOL mode with 4.7KΩ for alarm and 2.2KΩ for tamper) in my new house and zone 4 which has two detectors wired in series according to the below (other than the tamper jumper on the second PIR is set to 2K2 not 4K7), caused a Masking error on the system.
With the two detectors wired like the above, should both detectors be triggerd at the same time, it causes a Masking error on the panel. I had a look in the programming refrence and in the settings on the panel it's self, but could see no setting to disable masking errors on a given zone.
Now being that the Euro 76 pannel will generate a maksing error between 11.6KΩ and 22KΩ when in the 4k7/2k2 DEOL range as I have it set, the fact if both PIR's are triggerd will result in 4.7KΩ (Alarm PIR 1)+ 4.7KΩ (Alarm PIR 2) + 2.2KΩ (Tamper PIR 2) = 11.6KΩ, it's not suprising to me that it generated a Masking error.
Whilst I managed to fix the issue by setting each PIR's Alarm value to 2.2KΩ on the given zone in question, which stays within the "Burglary Alarm" resistance range regardless if just one or both of the PIR's are triggerd at given moment, I am not sure if this is the correct or best fix to my issue?
How would you have resolved the masking errror, same way as I have done or difrentley?
