ISM07 input as virtual input

[Howser]

I have an input connected to a ISM07 submodule that I have configured as RIO Input and have setup on/off responses  (SCS/RIO).

I have a need to use this input as an alarm input, and I cannot physically wire this, so I thought of using one of the alarm inputs as a virtual input.

What would be the ideal way of doing this?

1.  Change the input from RIO Input to Virtual Input on the ISM07? Would I still need to flag the alarm input as virtual?
2. Add actions (Virtual Input on and off) to the existing responses and set the flag of the alarm input as virtual?

Setup:

• Comfort Model: CM9001-ULT
• Comfort Version 8.005
• ScsRio (IRIO) Version 7.024

yes make the IRIO input a virtual input mapped to an unused zone on comfort. The comfort input would automatically becine a virtual input and you can use its on and off responses

I have done that, thanks.

I have set this input as an Entry Path, but it triggers the alarm immediately.

can you send the cclx file to support@cytech/biz?

[Howser]

Done.

I suspect it\'s because it\'s working as a N/O switch instead of a N/C switch. Setting the Zone Type to either Digital N/O or Digital N/C makes no difference.

This is a tricky one as you can\'t seem to change the behavior for Active/Inactive states unless you have a Door switch that is N/O by default - which I don\'t think is a good idea.

The other problem is that on reset it doesn\'t update the virtual zone state to what the iRIO has detected which is undesirable. (testing with iRIO with 7.027).

N/O or N/C does not make any difference for Zone Trouble. Zone Trouble is caused by wiring problems or mismatch between Zone shunts settings and EOL resistors eg if you have the zone shunts set to to EOL and you have EOL resistors on the zone or vice versa.

Your event log shows that you have zone trouble on zones 14 to 16 ie the LEM connected to Comfort.  You say that this is LEM01B without any shunts.  To test these zones, remove all the wires from zones 14 to 16, then use a short wire to short and open the zones and check if this causes zone trouble. If zone trouble occurs without any wires then it is due to a fault in the LEM01B. If there is no zone trouble then it is a fault in the wiring
The LEM on Slave 2 is an old LEM01-M2 without shunts so it cannot be used with SEM01C without EOL shunts

[Howser]

The challenge is that these zones do not always report Zone Trouble. I have to figure out what conditions do.

[slychiu]

If you have used the short/open method of testing the zones, and they do not report zone trouble, then tou can eliminate the LEM01 as the cause of the problem

[Howser]

When I test each LEM with short/open they do not report zone trouble.
