The voltage drops from 13.68V to 13.24V +-1 as though it were pulsing, Removing all attachments from the 12V & Com Voltage reads as 13.69(70)V to 13.40 (+.05)V pulsing every second or so this happens regardless of the PIR being attached The voltage rating for the PIR is anything between 12v & 30V so not sure what is going on anymore as the voltage drop is not that significant enough to cause a trigger. The only other things attached to the PSU on the SEM are: 1 X KT03 keypad 2 X SCS 6 switches The LEM & SEM board is roughly 1.5 years to 2 years old Serial Nos LEM C089008 SEM P052121 Just done the same test on main comfort Panel and it has similar voltage fluctuation but it does not trigger PIR PIR have been moved to main panel as they are not affected in the main panel (comfort II Ultra) Last edited on Monday Mar 19th, 2018 09:53 pm by Swiss-Toni |
