Pyronix Euro Mini - install question

[3george]

Just setting this up to replace an old Gardtec 800.

I have a choice of DP or DEOL for the input wiring and I'm just wondering what method is best. I have individual 6 core cable to each of the PIR / door contacts.

Any reason I should be choosing one over the other - what's the best practice I should be following here ?

PS - Gardtec is currently wired with resistors in each PIR which I'm assuming is DEOL but I think the values are different.

Many Thanks - David.

Your Euromini comes with a resistor pack
Replace the resistors in the pir with the correct value 2.2 tamper and 4.7 alarm and connect to panel.
If you choose double pole the you need to take jumper of pcb
EOL is the preferred way to wire alarm

Back in the "good old days" each zone on a (decent) alarm panel had two input pairs - an 'alarm' input & a 'tamper' input. A PIR would link back to the panel with 6 wires (3 pairs) - 2 power, 2 alarm loop & 2 tamper loop. Since each zone had an individual tamper loop as well as alarm loop it was easy to diagnose problems.

Although the Euromini can be wired in this manner it can only support a global tamper loop (and then at the cost of one zone). The downside of this is, that if used in DP mode, it cannot differentiate which zone has gone into tamper - only that there is a tamper event.

Wiring EOL alllows the panel to differentiate between alarm & tamper events using only a single pair of wires (since a different value of resistance is offered by the sensor for each event). You should use EOL.

And back in the old days pcbs where 4 times the size....
