Acenta GEN 4 PIR wiring

[bigmadandy]

Quick question regarding in install on one of these panels. I have 4 PIR's, will I need 4 separate cables going from the panel to each PIR, or do I take 1 cable to the first PIR and then go from this to the next and so on?

Hoping someone can clarify this for me.

Thanks a lot.

Separate cable to each PIR, wired into individual zones. There are ways to put multiple PIR's on the same cable and/or zone but its not recommended.

Last two words MOST IMPORTANT.

Now I can understand the sense of setting up zones, so you'd need to use separate cables, but what if there are 2 PIRs in one room.

2 PIRs in one room

Still should use separate cables. Makes everything so much easier to maintain, fault find, replace etc... Only time I would share the same cable is a situation like door contacts on patio doors.

If you was running out of zones then you could wire detectors together (and correctly) that are in the same room/zone but I would do this at the panel and only on a DIY system.

What difference does that make? Two detectors two cables, nothing difficult there.

Thirty five years ago+ I worked for a company that was one of those, install quick & cheap to get in as many as possible so the company could be sold for a rather large amount.

To cut what could be a very long story short. I left after about 2.5 weeks because I did not want to be associated with such a cowboy company. In my short time I found multiple detectors connected to one circuit, the highest number I think was eleven, yes eleven with no latch facility. How on earth was anyone supposed to fault find. The panel of the day was the M&W CPF2! and I'm not joking.

Got home one night and decided I have to go, phoned a friend and took the vehicle back to the office, parked on the road outside, keys through the letterbox.

No further contact, started with another, better, and a national company the following week, for about 10 years, I think.

Sorry about all this, my first two lines started me off thinking and then remembered the above.

Phew, glad all that's over. Must not write any more.

Sorry bigmadandy, got carried away.

One cable, one detector.

Thanks everyone.

Cheers. On the diagram it shows the tamer connection linked, this is what make me thing you needed a cable to each PIR, and then perhaps a cable linking them via the tampers? Do you just link them out at the board using little bits of cable or something? The person I'm doing it for (family favour) has lost the instructions

You wouldn't have separate cables to the PIR, and then a cable linking them via the tampers. Each cable will supply + and - for the power, 2 cores for the tamper, and 2 for the PIR signal. If you use a cable to each PIR, then everything covered.
