you can have a wireless bell on any spare wireless zone, so in theory if a 32XP-W has only wireless bells it can have 32 of them connected.
hard wired its a little more complicated in that its about power consumption, but in SCB mode you can get over 10 times the wired bells as you would in SAB mode.
so Odyssey X not back light (40mA), excludes strobe at(100mA), would use 30mA SCB (13 bells) instead of 1 x 405mA on SAB but you get the idea.
