Wiring of Vista 20P Panel
« on: August 12, 2017, 01:07:43 PM »
I have an active thread going (wireless sensors not being detected), but I'm getting errors when I try to post in that thread.

Since I'm not able to get system to "see" any of the wireless sensors, I was hoping that someone could look over my wiring to make sure that I have it setup correctly.  I'm replacing a Vista 20 panel with the 20P and I intended to wire it as it was on the old panel.

Here is how it's currently wired:
T1: AC
T2: AC
T3: Red from Bell, 1st Tamper Wire (I can't identify it, but I think it's a tamper)
T4: 2nd Tamper Wire (ditto), Blacks from Bell, Motion Detectors, Keypads, and Receiver
T5: Reds from Motion Detectors, Keypads, and Receiver
T6: Greens from Keypads and Receiver
T7: Yellows from Keypads and Receiver
T8: 1st Wired Door Contact (with Resistor) - Programmed as Zone 1
T9: 2nd Wired Door Contact
T10: White from Motion Detectors - Programmed as Zone 2
T11: Green from Motion Detectors (with Resistor)
T12: Jumped Resistor to 13
T13: Jumped Resistor to 14
T14: Jumped Resistor to 13
T15: Jumped Resistor to 16
T16: Jumped Resistor to 17
T17: Jumped Resistor to 16
T18: 1st Wired Door Contact (with Resistor) - Programmed as Zone 7
T19: 2nd Wired Door Contact
T20: Green from Bell (with Resistor) - Programmed as Zone 8
T21: Brown from Telephone Line
T22: Gray from Telephone Line
T23: Green from Telephone Line
T24: Red from Telephone Line

Your wiring description looks okay to me.

The one thing I would have done differently is land the EOL resistors on the negative (Lo) side of your zone loops.

The purpose of EOLRs at the end of the loop (last contact) is supervision against your loop wires being shorted (e.g. by a staple, nail or drywall screw; or by being abraded and/or pinched by/between metal pipes or air ducts where the wire is run in utility spaces and walls. That's rare, but it does happen. I've encountered it a few times--I'd say less than once a year while I was working (retired now).

Shorts from staples, nails, or drywall screws happen during installation and construction and nearly all of those cause their problems when the system is new. After a few years, it's more common (but still relatively rare) to see problems caused by being pinched or rubbed by metal pipes and/or ducts.

If you land the resistors on the negative side of your loop terminals, and ground your Vista panel (which it should be anyway), then your loops will be supervised against ground faults (shorts to ground) and  a pipe or duct pinching or abrading through your loop wire insulation will cause a problem that you can trace and locate, usually before it severs the wire.

As I said, this is rare, but if it does happen, you want an early warning, and landing the resistor on negative is a simple precaution. On the positive side of your loop, your resistor does nothing for you at all.

Hello ChosunOne,

I got your message about only using one post for multiple issues to keep the continuity going.  I told understand - you guys are a great resource for us DIYers and we need to make life a little easier when we're asking for help.

This post below was an old one and I didn't want to copy it in to my most recent post - hope you don't mind.

1. In the wiring list that I have below, there are two wires on T3 and T4 that I wasn't able to identify.  Does it make sense that those are the tamper wires?
2. You indicated below that I should land the EOL resistors on the lo side of the loops.  I tried that and I got an alarm when I powered the panel up.  I am now realizing that I was only given the EOL programming option (in *56) for 3 zones, but I reversed the wiring for 4 zones.  I have resistors on the wiring for four zones:
Zone 1 - type 1 (I was not able to select the EOL type for this zone, and I see that it is automatically set for EOL in the manual)
Zone 2 - type 4 (EOL = 0)
Zone 7 - type 3 (EOL = 0)
Zone 8 - type 7 (EOL = 0)

Should I only reverse the wiring for Zones 2, 7, & 8?

Well, this is embarrassing. I don't know how I missed this the first time I read your OP back in August, but---
T3 & T4 are for local alarm notification (siren, bell, strobe, buzzer, etc) only. Whatever the extra wires are, they aren't going to a tamper switch. Something else is receiving power when your alarm sounds.

Your panel went into alarm when it was powered up?  What zone(s)? Make sure you're pairing the zone loop wires correctly: Since the negative sides of zones beyond Z2 share a common gound, it's easy to mix up loop wiring and have, for instance Z7 & Z8 crossed with each other. I've done that myself when I wasn't paying attention.

Remove the wires at panel from any zone that goes into alarm on power-up and check to see if there's a short(continuity) to ground.

Do you have field *39 set to power up in previous state? I recommend having the panel always power up disarmed, it saves false alarms after extended power outages.

I remembered that I have two audibles on this system:  the outdoor bell and an indoor 2-tone siren.  I see the bell wiring (red/black/yellow/green) and I assume the siren wiring (2 whites going to T3 and T4) are the "unknown" wires.

Does that make sense?

Makes perfect sense. 

You have an outdoor BELL on your system?!

Maybe "Bell" isn't the correct term.

I can't attach a picture, but our alarm sounds in two places:

1. Indoor siren (two tone) - this appears to just have two wires (T3 and T4).
2. Outdoor bell - this is in a 12" by 12" metal box with the access door wired to be tamper-proof.  This has 4 wires (T3, T4, T19, & T20)
