I’ve tried wiring like this but when I do a walk test it won’t pick up the pir as zone 1, I’ve linked across the tamper in the control panel and only connected to the zones and + and -Resistors are built in in the texecom pir and values can be selected to suit different panels. For texecom is 2k2 and 4k7
For testing purpose set the pir to guard and do all the tests. When confirmed that all is OK change to whatever you need to be
