rln36 alarm but no video

user_639868941582417

I have the RLN36 with a RCL823A. Now playing with the alarm outputs to switch on lights thu wireless Thrust switches. That seems to work fine. However I notice I get short alarms, alarm out is activated, light goes on for up to 10-12 seconds, but no video recording. Also LED spot lights on the 823 are not activated. On longer alarm durations the lights go on, recording starts, and LED spot lights go on. I can't figure out what is causing this?

I have modified the RLN36, removed the cooling fans and fitted a SSD. I used a 320mm long 20x20x20 aluminium U section I had as heatsink. Measured with a fluke infrared, the processor stays at 45-47C surface temp, the U section is at 30C on top of it, and 28C at the ends. This at 20C ambient. Also used two pieces of light foam as a spring between the U section and cover, it ensures a minimal contact force with the processor. The fan connectors are impossible to remove due to the red glue. I've cut the wires at the connector and used tape as insulation as the alu profile sits right above it. The RLN36 now makes no noise at all, except for the alarm relay when activated. It only records on alarm.
