SP ECI FI CAT I ON & DESIGN
The auxiliary power supplies are additional 15 V
power
sources that are used to power additional keypads and
contact closure interfaces, when the power supply capacity of the processor is exceeded. A 4 Series P5 processor
can power a maximum of 150 LEDs. An 8 Series P5 processor can power a maximum of 350 LEDs. Wireless series
processors do not power keypads because each RF keypad
is powered locally. For keypad LED counts, see Table 1 on
pg. 40.
