The amount of current drawn by a PIR is negligable.
You only need one pair for power.
I use COLOUR/White for +ve, WHITE/Colour for -ve.
You never know when you will need the 4th pair for something else :-)
Nothing inherently wrong with what you propose....just my ?0.02

Folks
Quick query, when using CAT5 for wiring up PIR sensors etc. Is there any
standards regarding which coloured wires to use for what. I was thinking
of doing the following:
BROWN / White & WHITE / Brown - LIVE 12V (both wires to reduce
impedance)
BLUE / White & WHITE / BLUE - 0V
ORANGE / White & WHITE / Orange - Alarm Circuit
GREEN / White & WHITE / Green - Tamper Circuit
That way the old blue / brown for neutral / live is maintained.
Any comments welcome.
Steve
