Well I was meaning, maybe you did this.  Pull the fuse, put the fuse
back in, the moment you put it in does the LED flash?  Maybe the alarm
control unit is seeing a low voltage and "turning off" the logic,
therefore everytime the voltage drop ends (end of beat impulse) the LED
flashes as if the power was re-applied.
