LEDs: Switch 7
When enabled, the red PIR and green Ultrasonic Activity LEDs on the sensor will
light when the associated technology detects motion.
PIR Sensitivity: Switch 8
• Minimum forces a reduced detection range for the PIR.
• Max./SmartSet causes the DT-300 to monitor the controlled environment and
automatically select the maximum sensitivity that will provide reliable operation
without false detection. This setting is constantly updated.
MANUAL ON FUNCTION
The Manual ON function is facilitated by installing a momentary switch such as
Watt Stopper LVS-1 Momentary Toggle Switch, or RS2-3 Low Voltage Momentary
Switch. The switch connects to the sensor's Manual (Man.) Switch and Common
terminals as shown in the wiring diagram. Each time the switch is pressed, the load
changes state. The sensor's operation as related to the manually operated switch is
determined by DIP switch settings for Occupancy Logic.
Manual Mode (Trigger Option 6 or 7): In this mode, the switch is required to turn on
the load. The sensor keeps the load on, based on occupant activity. After the time
delay ends, the load turns off and the manual switch must be used to turn the load
on, if there is no movement detected within the 30 second re-trigger period.
Automatic Mode (any Trigger Option except 6 or 7): These options use occupancy
triggers as well as switch activation to turn the load ON. A manual switch provides
the following additional functionality:
a. The load can be turned ON using the manual switch and it stays on according to
the occupancy logic setting. The time delay operates as programmed. When the
load turns OFF due to lack of occupancy detection, it can be turned ON again by
occupancy detection or the switch.
b. Activating the manual switch while the load is ON turns the load OFF.
• When the load is turned OFF manually, as long as the sensor continues to
detect occupancy the load stays OFF. Five minutes after the last occupancy
detection, the lights stay off and the sensor reverts to the automatic-on mode.
• When the load is turned OFF manually, pressing the switch again turns the
load ON and the sensor reverts to the automatic-on mode.
• Once returning to automatic-on mode, either the switch or occupancy
detection can turn the load ON.
