Optex AX-70 With 5816-OD Transmitter

Can anyone tell me how to wire and configure an Optex AX-70 beam with a Honeywell 5816-OD to trigger a Lynx panel? As of now, I have the beams on and aligned. I have wires connected to "Alarm" on the receiver beam with NC on the 5816-OD. I can send signals from loop 2 but nothing from loop 1.

Does the AX-70 require a separate relay?
