LEGRAND Wattstopper DT-200 Manual De Instrucciones página 2

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.
The DT-200 is designed for a ceiling height of about 8-10 feet. Mounting above or below this range
will significantly affect the coverage patterns. As a general rule, each occupant should be able to
clearly view the sensor.
Masking the PIR Lens: Opaque adhesive tape is supplied so that sections of the PIR lens can
be masked. This restricts the sensor's view and allows you to eliminate PIR coverage in unwanted
areas such as hallways outside of the desired coverage area. Since masking removes bands
of coverage, remember to take this into account when troubleshooting coverage problems. The
Ultrasonic coverage cannot be masked, but you can adjust its sensitivity to reduce the coverage
area.
Each Wattstopper BZ series power pack can supply power for 3 DT-200
sensors. When using more sensors than this, multiple power packs are
required.
Refer to the wiring diagrams for the following procedures:
Connect the LOW VOLTAGE:
• RED wire (+24VDC) from power pack to the red wire on
the sensor
• BLACK wire (Return) from power pack to the black wire
on the sensor
Wiring a single lighting load controlled by
occupancy–connect:
• BLUE wire from power pack to the blue wire on the
sensor
To add a Momentary manual switch such as the LVSW
Momentary Toggle Switch, to the above applications–connect:
• Wire from one side of switch to the grey wire on sensor
• Wire from other side of switch to the red wire on sensor
Wiring the Isolated Relay (The Isolated Relay is rated for
1A@30VAC/VDC):
Connect the wires necessary to the application that requires
this output.
• Relay Common (must be used for proper operation) is the
green wire
• N.O. (Normally Open)–Closed when occupancy is
detected, is the orange wire
• N.C. (Normally Closed)–Open when occupancy is
detected, is the brown wire
