Zone Trouble when zone linked out

[ComfortGeek]

Hi - I have a problem with trouble condition on zone 5.

Even when I link the zone out and move the jumper towards the terminals so it knows there are no EOL, it still goes into a trouble condition.

Any ideas why? Could the zone be broken?  That\'s a pain as I need it!

Thanks

There may be an external voltage on the zone terminals or wires

Remove the wires from the zone and see if the trouble remains

Thanks.

Yes, I\'ve tried that and I still get a trouble condition.

Here\'s what I\'m doing.

1. Moving jumper close to terminals so it knows there\'s no EOL resistors.
2. Putting a piece of continuous wire between the zone terminals so the zone is closed.
3. Set the zone as type doorwindow and it goes into trouble alarm
4. I set to zone type switchNO and switchNC to see if that makes any difference and still there is a trouble alarm whatever I do

I cannot see any other wires touching the terminals. Of course, zone 6 is connected to the shared common terminal as zone 5. There\'s never been a problem with the zone 6 which is a normally closed heat detector.

I have removed zone 6 and the problem still occurs.

Do you have any other ideas what it could be?

Hi.

Update on this issue

If I set the zone as door window or switch NC, and the zone is left open, ie no link wire, and reset comfort , there is no trouble alarm. As soon as I close the circuit by putting a wire across the zone terminals, there is a trouble alarm.

Any ideas what this could be?

Thanks as always

Do you have a multimeter to take some voltage measurements?

1. with the shunts in NO EOL position ie closer to the terminal blocks (as you have now), open the zone (remove the shorting wire) and measure the voltage from Zone to common,
2. with the shunt in Double end of line position ie away from terminal block, open the zone (remove the shorting wire) and measure the voltage from Zone to common
3. Remove the shunt completely, open the zone (remove the shorting wire) and measure the voltage from Zone to common

This will tel us if there is a fault

Hi.

The readings were as follows;

1. 0.596 volts - shunt in no Eol position
2. 1.22 volts - shunt in eol position
3. 1.22 volts - shunt totally removed

Any ideas?

Thanks

The voltages are too low. It appears like the input is damaged.

Do you have a spare zone that you can use?

[ComfortGeek]

Unfortunately not, I need all 64 now.

Good to know I\'m not doing it wrong though

You can have a maximum of 5 slaves so total of 96 zones now

Thanks

But it buy a Slave just for one zone is a bit excessive!
