EC-FF345 not pairing with IQ Panel 2

I’m having trouble pairing my EC-FF345 with my IQ Panel 2. I put the panel in Auto Learn Sensor mode, and following the instructions, I then clicked the learn button (not tamper) on the EC-FF345. That didn’t work, despite trying to click it several times over multiple occasions. Next I tried to pair it using the tamper switch on the EC-FF345, despite the instructions saying not to pair it this way. Still no luck.

Is the EC-FF345 not compatible with the IQ Panel 2?

As best I can tell, the EC-FF345 is not compatible with the IQ Panel 2, which explains why it isn’t picking up any signal whatsoever. I think I need the EC-FF319. Is the SLX-AD-T3 the same as EC-FF319? They seem to be identical, just sold by a different company and therefore a different SKU.

The EC-FF345 is a 345 mhz sensor that is not made for Qolsys Panels. In general Qolsys Panels use GE 319.5 sensors. 345 mhz sensors are for Honeywell and 2GIG panels.

The firefighter products are now sold under manufacturer distinct SKUs. You would indeed want the SLX-AD-T3.
