Standard low voltage installation

with remote power pack
in accessible tile ceiling

SPECIAL NOTES: One Power Pack can operate 4 sensors and all

low voltage wires are connected in parallel. Some existing lighting
systems are wired directly from Breaker Control Cabinet and there­fore have no light switches. For this type of lighting system, it is
sometimes more convenient to install Power Packs close to the
Circuit Breaker Control Cabinet. This allows for ease of circuit identi­fication, and also wiring of low voltage cable to sensor units.

TRPS are UL Listed.
