Electronic Alarms and Home Security Devices - Vista 20P, issue with wired contact

Hi,

I am a newbie to home security systems and have just installed a vista 20P with 5833 for wireless. I have 9 wireless contacts and 3 wired contacts. Everything seems to be working fine except 1 wired contact.

I have it configured for Zone 4, NC (normally close). This is the only contact in zone 4. Its the same config as the other 2 wired contacts but I am getting a fault on Zone 4. I have tried -

1. changing the contact to a new one but same issue.
2. I checked the cable and the cable is fine.I mean end to end connectivity is good.

Any ideas for resolution will be greatly appreciated.

Thanks.

Did you try to use just the E.O.L. in the panel? If that clears zone problem, check loop resistance and any shorts to ground or foreign voltage on the loop.

Isn't the EOLR supposed to be optional ? I am not using any on the other 2 zones and they seem to be working fine.

For some reason the wire for the front door and wire for front motion sensor were taped together. All the other wires were hanging independently. I am just wondering if that means anything. This is a new house and it was pre-wired. The installer wrote identifiers on the wire using a marker.

In the absence of a volt meter, i improvised for the wire test. I wired the power from the transformer through the wire for front door. power to the panel was ok when the door was closed but when I opened the door, the system switched off. so that meant the wire and contacts are ok.

Are the EOLR required on specific zones ?

You may have a bad zone. Try just a piece of wire acroos the zone if that doesn't work try switching to eolr put a ek resistor across the zone terminals with no wires just the resistor. if that doesn't work try disconnecting all wires but the keypad and leave the resistor across the zone with no wires if it clears reconnect everything one at a time watching the keypad as you connect them.

yes the eolr is optional. you mentioned prewire you may have a short to ground like TN mentioned follow my steps above.

So this is what I have now -

Zone 2 - wired contact - NC
Zone 3 - Wired contact - NC
Zone 4 - Direct wire connected on the panel - NC
Zone 5 - wired contact - The bad one (I shifted from 4) - NC
Zone 6 - Direct 2k resistor connected on the panel - EOL


Zone 4,5,6 show up as faulty

The resistors requirement is controlled by the setting you make for EACH zone in *56 programming (zone 1 is _always_ EOL). There's no autoconfigure for this, in the hardwire type prompt your choices are:
0 = EOL
1 = NC
2 = NO
3 = zone doubling (ZD)
4 = double-balanced (DB)

It looks for what you _tell_ it to look for.

What did you set the zone (both zone type and input type) to be when you programmed the zones?

The Zone type is 1 (Entry/Exit) and hardware type is set to 1 (NC).

This is the setting on all 3 of the wired contacts. Two of them are ok.

And what happens if you replace your field wiring with a simple wire jumper from zone 4 to common?
