Programming Guide
CONTROL SCHEME
The following schemes can be programmed via CONTROL setting of the SRP-281. Depending on the connection of wired Low Voltage Occupancy Sensor (LVOS) and
grouped OS-NET Sensor (ONS)/OS-NET Button (ONB), the ON-PPU may control the load in slightly different patterns.
DEVICE LED ACKNOWLEDGEMENT
The device will acknowledge the setting success or failure with following
indications by device LED in BLUE or GREEN. BLUE means the device is
unlinked and GREEN means the device is network linked.

Following are basic wiring diagrams for typical controls, consult with an
IR-TEC team member for correct wiring diagram if a more complex control is
required.
A. Occupancy/Vacancy Sensing Control
NOTE: For Vacancy Sensing Control (VSC), at least one OS-NET Button
should be installed and grouped with the ON-PPU-301 to enable
manual-on control.

All line voltage wiring connections should be
made inside of junction box.
To obtain optimal wireless communication,
avoid placing the device behind a metal
mesh/plate.
To enable wireless network control, the
ON-PPU-301 must be grouped and linked with
the other OS-NET devices. An “ungrouped”
ON-PPU-301 with low voltage occupancy
sensor connected will only operate in
standalone control.

CONTROL = ON/OFF
The load will be switched ON when ON-PPU receives 1) control signal from a wired
LVOS, or 2) wireless command from a grouped ONS/ONB, and switched OFF when
programmed delay time elapses or receives the OFF-command from a grouped OSB.
If the load was switched OFF via an OSB, the ON-PPU will operate in Presentation
Mode. The load will remain OFF if motion is detected before the delay time elapse.
The ON-PPU will resume to auto-ON, auto-OFF control after delay time elapsed.

CONTROL = VSC
VSC refers to Vacancy Sensing Control. This control requires user to turn ON the load
by pressing a grouped OSB, and the ON-PPU will turn OFF the load when delay time
elapses or receives the OFF-command from a grouped OSB.

CONTROL = PLC
PLC refers to Plug Load Control. The ON-PPU will enable the plug load power when it
receives 1) control signal from a wired low voltage occupancy sensor, or 2) wireless
command from a grouped OS-NET Sensor/Button, and switch OFF the plug load
power after the area is vacant and programmed delay time elapsed.

The DELAY timer of ON-PPU will only be activated by receiving the wireless command
from grouped OS-NET devices.
The ON-PPU will transmit OCC signal wirelessly for group control when wired LVOS
detects occupancy.
To prevent unintentionally shutting off the power for plug load control, ensure to set the
DELAY of the ON-PPU longer than the setting of grouped ONS.
Under PLC mode, all OFF-command from the OS-NET Button will be ignored.
