DESCRIPTION
The PS-P24-CM 360 ° passive infrared (PIR) occupancy sensors turn lighting systems 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 the sensor detects
occupancy. After no movement is detected for a user specified or Autoset time (5s to 30
minutes) the lights are switched off. A "walk-through" mode can turn lights off after only 3
minutes, if no activity is detected after 30 seconds of an occupancy detection.
The PS-P24-CM operates on 24V supplied by PS-PP3000/PS-PP7000 Power Packs.
COVERAGE PATTERN
°
The PS-P24-CM provides a 360 coverage pattern, up to 1200 square feet. The coverage
shown represents walking motion at a mounting height of 8 feet. For building spaces with lower
levels of activity or with obstacles and barriers, coverage size may decrease.

PLACEMENT GUIDELINES
Depending upon obstacles such as furniture or partitions, the area of coverage may be less or
more than the sensing distances shown in the coverage pattern. This must be considered
when planning the number of sensors and their placement. It is also recommended to place the
sensor 4 to 6 feet away from air supply ducts as rapid air currents or the differences in tem-
peratures may cause false activations.
-01-
Mount the sensor to the ceiling. The PS-P24-CM is designed for a ceiling height of about
8-10 feet. Mounting above or below this range will significantly affect the coverage patterns. Be
With Light Level Feature aware that as you decrease the mounting height, you decrease the range and increase the
sensitivity to smaller motions. Conversely, when you increase the height, you increase the range
and decrease the sensitivity to smaller motions. At heights of more than 12-14 feet, you may start
to significantly reduce sensitivity. As a general rule, each occupant should
be able to clearly view the sensor.
Often the best location to install a PS-P24-CM in a closed
office is off-center. Avoid placing a sensor directly in line with
an open door through which it has a clear view out, as the sen-
sor may detect people walking by.
Open Office Area Coverage:
° to 131 ° F (0 ° to 55 ° C)
To get complete coverage in an open office area, install
multiple sensors so that there is an overlap with each
adjacent sensor's coverage area.
For large areas of coverage use multiple sensors.

WIRING DIRECTIONS
TURN POWER OFF AT THE CIRCUIT BREAKER BEFORE INSTALLING
Each PS-PP3000 or PS-PP7000 power pack can supply power for 6 PS-P24-CM sensors. When
using more sensors than this, multiple power packs are required.
Connect the low voltage:
44 ft
13.4m
RED wire (+24VDC) from power pack to the +24V terminal on the sensor.
BLACK wire (Common) from power pack to Common terminal on the sensor.
Wiring a SINGLE LIGHTING LOAD CONTROLLED BY OCCUPANCY - Connect:
BLUE wire from power pack to Control Out terminal on sensor.
Wiring multiple SINGLE LIGHTING LOADs CONTROLLED BY OCCUPANCY, DEPENDENT
ON LIGHT LEVEL (AMBIENT LIGHT) - Connect:
BLUE wire from power pack to Control Out terminal on sensors.
To add a MANUAL SWITCH such as a Momentary Toggle Switch, to the above applications-
connect:
1. Wire from one side of switch to Common terminal on sensor.
2. Wire from other side of switch to Man Switch terminal on sensor.

LIGHT LEVEL FEATURE
Turn the potentiometer on the sensor to the "-" if adequate ambient light exists, the output of
sensor will be inhibited, and the load can not be on; only when the ambient light is down to a
certain level the sensor will automatically turn on. Therefore, potentiometers require custom-
ers to adjust in accordance with the location and the ambient light level. This feature can
effectively turn on the load when adequate ambient light exists, in order to achieve energy-
saving. Turn the potentiometer on the sensor to the "+", regardless of the ambient light level.
The load will be on as long as there are signals from occupancy.
Avoid mounting the sensor close to lighting fixtures.

Adjust during daylight hours when ambient light in the area is at desired
level. Open the Front Cover and locate the Light Level. See Sensor
Adjustment.
MOUNTING THE SENSOR
Using an Octagonal J-Box
1. Pull the low voltage wires from the power pack into the J-Box through the conduit knockout.
2. Connect the low voltage wires to the appropriate terminals on the sensor.
3. Loosen the appliance mounting screws attached to the J-Box.
4. Align the sensor in the J-Box so that the mounting screws on the box match the key holes on
the sensor's rear housing.
5. Push the sensor up into the J-Box and twist it so that the mounting screws are seated in
the keyhole slots.
6. Tighten the two screws to secure the sensor to the J-Box.
7. Snap the front cover onto the sensor.
