Hello all, as you may be aware from my other posts, I've been upgrading an old G3 alarm system using the installed wiring but all new components and have installing a Texecom Premier Elite 24 using Texecom Premier Elite Compact PIRs (and some other stuff). This post is specific to the PIRs.
The good news is that the system is working. I've wired it double pole (because that is basically how the old system was wired and the two PIR zones (3 PIRs per zone) have a global tamper using the Aux/Tamp and it all works. The PIRs are programmed as 'normally closed' as is, of course by default, the Aux/Tamp circuit. It's all tested, alarms when expected, shows tamper when I pop off a PIR cover, etc. so I'm happy and *could* leave it all working.
However, I'm retired, we are in lock down (in Wales) and it's raining (it's Wales) so I'm sorely tempted to rewire the PIR circuits using an EOL approach which is the approach recommended by by the professionals. I've been reading up on this an my understanding is as follows:
Each PIR zone forms a single loop and only two terminals (1 & 4 in the image below) are used. The zone wire leaves the control panel terminal, comes into terminal 1 of PIR 1 and then out of terminal 4 to the next PIR terminal 1 and so on until the end of the line when the wire exiting terminal 4 on the final PIR goes back into the remaining zone terminal on the control panel. This is then programmed as EOL/Double Pole.
The circuit is completed between terminals 1 & 2 by a 4K7 resistor and between 2 & 3 by a 2K2 resistor and between 3 & 4 by the nature of the lid being on and therefore the tamper circuit being closed. So far, hopefully, so good.
I understand that these PIRs have inbuilt resistors which I believe to be the jumpers on the left numbered 5 & 6 above. With 5 being the alarm and 6 being tamper. However, try as I might, I've been unable to understand why there are four sets of jumpers (A, B, C & D) per set.
I think (from viewing pictures of other installations) that set A are the correct values (i.e. 4K7 for alarm & 2K2 for tamper). However, if that is correct, I fail to understand why B, C & D are provided. What is the point of them?
I've failed to find this information either in the manual or online.
Any guidance gratefully received.
