wet contact

[paauto]

Is there a wet contact version of the I/O Linc available? I am trying to interface my existing Napco alarm to my ISY994 and the Napco is configured with a 24v wet contact. I can re-configure the Napco and turn the contact into a dry contact, but it will take soem work by my installer (i.e. time and $) and I may loose some functionality on how the system signals different types of alarms (burglary vs. fire).

The Sense circuit is digital (5V DC), expecting the I/O Linc GND to turn the Sensor on. The I/O Linc could be damaged if 24 AC is applied to the Sense input. Also an AC voltage would cause the Sensor to cycle even if it did not destroy the I/O Linc which I suspect it would.

Use one of these to interface the alarm to an IOLinc: http://www.smarthome.com/1299/ELK-912B- ... olt/p.aspx

Thanks. I posted on the SmartHome Forum and received the same advice. That's what I'll do.

You would want the 3 amp version
