WARNING
Turn the POWER OFF at the circuit breaker
before installing the sensor
Read and understand these instructions before installing. This device is
intended for installation in accordance with the National Electric Code and
local regulations. It is recommended that a qualified electrician performs this
installation. Make sure to turn off the circuit breaker or fuse(s) and make sure
power is off before wiring the device.
Use copper wire only.
The MPW-L provides a 150° coverage pattern. The coverage shown represents
walking motion at a mounting height of 10 feet. For building spaces with lower
levels of activity or with obstacles and barriers, coverage size may decrease.
The MPW-L passive infrared (PIR) occupancy sensors turn lighting on and off
based on occupancy and ambient light levels. The light level feature keeps lights
from turning on if the ambient light level is sufficient. The sensors can be
configured to turn lighting on, and hold it on as long as PIR technology detects
occupancy. After no movement is detected for the selected time delay, the lights
switch off.
The MPW-L operates on 24V supplied by the MPP-24 Power Packs (Not
Included)

WARRANTY INFORMATION
This device is warranted to be free of material and workmanship defects for 2 years from
the date of purchase. Original receipt or proof of purchase from an authorized retailer must
be presented upon warranty claim. ALL claims must be verified and approved by Enerlites,
Inc. Warranties from other Enerlites products may vary. This warranty is nontransferable
and does not cover normal wear and tear or any malfunction, failure, or defect resulting from
misuse, abuse, neglect, alteration, modification, or improper installation. To the fullest
extent permitted by the applicable state law, Enerlites shall not be liable to the purchaser or
end user customer of Enerlites products for direct, indirect, incidental, or consequential
damages even if Enerlites has been advised of the possibility of such damages. Enerlites’
total liability under this or any other warranty, express or implied, is limited to repair,
replacement or refund. Repair, replacement or refund are the sole and exclusive remedies
for breach of warranty or any other legal theory.
The Sensor Switch is programmed for Occupancy Mode only.
Automatic Turning On/Off the Load
Once the power is on, the load will be turned On according to the
occupancy settings. The sensor time delay operates as programmed.
When the load turns OFF due to the lack of motion detection, the
load can be turned ON again by occupancy detection or switch
activation.
The Sensor keeps the Load On until no motion is detected plus the
set time delay, load(s) will be turned Off automatically.
OPERATION
PIR Activity LED does not flash:
NOTE: When power is initially applied to the sensor, there is a warm-up
period of up to 1 minute before the LED is active.
WARNING: Turn off the power at the circuit breaker before
installation. Lights do not turn on with occupancy, and the
following condition exists:
1.. If the sensor’s Light Level has been turned to minimum (at positi
1), the lights connected to the Light Level Output might be held off
because of the level of ambient light in the controlled area. To test
whether the Light Level adjustment is the problem, cover the PIR lens
and PIR Activity LED with your hand to see if the lights turn on. If
the lights turn on, the Light Level setting was keeping the lights off
(see, “Sensor Adjustment” for readjustment).
2.. Make sure the wire is connected righ
1.. The sensor may be experiencing activations from outside t
controlled or from some type of interference (see “Unwanted Sensor
Activations” below).
2.. Make sure the wire is connected righ
1.. Check that the circuit breaker or any wall switch connected to t
sensor has been turned back on.
2.. Make sure that the PIR Sensitivity is set for Ma
3.. Make sure the wire is connected righ
