Pepper spray traps? Really? Cool. You'll need an aux power supply all right.
It's a PC5204, and it needs it's own 16.5 VAC/40VA transformer, and battery.
Use a relay to cut the siren while the pepper spray trap is drawing it's 800
mils. I think the 1832 has zone follower attributes on the pgm outputs,
hmmm...seems I saw that. Donno.
