OAC AND VAC MANUAL MODE OPERATION:
1. SWITCHES ARE REQUIRED TO TURN
CORRESPONDING LOADS ON.
2. LOADS TURN OFF WHEN SENSOR
TIMES OUT OR WITH SWITCHES.
3. IF DAYLIGHT SENSOR IS ENABLED AND
LIGHT LEVEL IS ABOVE SETPOINT,
SWITCHPACK CONNECTED TO YELLOW
LEAD WILL NOT TURN LOAD ON.
OAC AUTOMATIC MODE OPERAT ION:
1. WHEN SENSOR ACTIVATES, BOTH
LOADS TURN ON.
2. SWITCHES CAN BE USED TO TURN
LOADS ON OR OFF.
3. IF DAYLIGHT SENSOR IS ENABLED AND
LIGHT LEVEL IS ABOVE SETPOINT,
SWITCHPACK CONNECTED TO YELLOW
LEAD WILL NOT TURN LOAD ON.

* When creating a sensor coverage layout in a cubicle space, best
practice is the use the minor motion coverage pattern as maximum
coverage area. Results may vary based on cubicle height and ceiling
height. (Cubicle wall height should not exceed 71 inches).
