Re: Alarm Panel For Detached Garage

["bjordan" <jordanbrian@xxxxxxxxx>]

I'll need the extra power supply, because I'll want an LED keypad and
motion detection (or two twinned) in the garage.

The PC5204 manual indicates that it pulls 20mA off the keybus.  I
suppose the 1A of power it adds comes off the AUX terminal.  Can I jump
the AUX to the incoming keybus red so that the PC5204 powers itself?  I
ask because the main house system (PC5010) is already maxed out on
keybus power.

Also, can the PC5204 both power itself and add power back through the
keybus that connects it to the panel?  In other words, if a system was
overtaxed on power, can a PC5204 be added to the system with the AUX
connected to the system keybus?

The PC5204 manual is very brief!
