4204 issues

Hey all. Have 2 4204 modules on a 128BPT and I’m having issues of the modules activating. Here’s the setup, there’s 1 4204 on partition 1 and other is on partition 2. Partition 1 for security and partition 2 for fire. I have the partition 2, relay #1 programmed to activate the bells in the event of a fire under 39 = fire alarm but for some reason anytime the system is in a fire alarm event on partition 2 the relay refuses to activate however the onboard bell circuit is going off. I have confirmed 13 volts on the relays at all times even during alarm events (both relays are powered by a separate power supply and the data bus is wired in series). Any way to solve this issue?
