s the name implies, The NightLite Sensor (WSD-NL Series) is
a combination 24/7 night light and occupancy sensor capable
of turning the lights off when the room is vacant. The NightLite
Sensor is the perfect solution for Hotel and Hospital bathrooms
where guests tend to leave the light on all night. A user programmable time delay
ensures that once the room is vacated the sensor will time out and turn off the lights.
The WSD-NL comes factory set in Semi-Automatic (Manual On) mode meaning the
button needs to be pushed in order to turn on the lights. Besides Semi-Automatic
operation, several other On Modes and Switch Modes can be programmed into the
sensor using the front push-button. For rooms with obstructions the WSD-PDT-NL
should be considered.

The NightLite Sensor
SENSOR OPERATIONS
The sensor detects changes in the infrared energy given off by occupants as they
move within the field-of-view. If the push-button is pressed (when in Manual On
mode) or if occupancy is detected (when in Automatic On mode), a self-contained
relay switches the lighting On. The sensor is line powered and can switch line
voltage (see specifications). An internal timer, factory set at 60 minutes, keeps the
lights On during brief periods of no activity. This timer is push-button programmable
from 30 seconds to 2 hours, and is reset every time occupancy is re-detected. This
state-of-the-art sensor requires no manual sensitivity adjustments.

OPERATIONAL MODES
On Modes (*Default)
Automatic On - The sensor automatically turns the lights on when the sensor
detects occupancy.
Manual On (Semi-Automatic)* - The occupant must press the sensors button
to turn the lights on.
Reduced Turn-On - The sensor is set to initially only detect large motions,
effectively ignoring any reflected PIR signals while still sensing occupants when
they enter the room. Once on, the sensor returns to maximum sensitivity.
Switch Modes (*Default)
Predictive Off - Pressing the switch overrides the lights off and temporarily
disables the occupancy detection. After an exit time delay (default 10 seconds)
the occupancy detection reactivates and monitors for an additional grace
period time (default 5 seconds). If no occupancy is detected during this period,
the sensor will revert to Automatic On operation. If occupancy is detected, the
sensor will remain in Permanent Off mode requiring the switch to be pressed
again in order to restore the sensor to Automatic On.
Permanent Off*- Pressing the push-button switch will turn the lights off. The
lights will remain off regardless of occupancy until the switch is pressed again,
restoring the sensor to Automatic On mode.
Switch Disable - Prevents user from manually turning off the lights via the
push-button. SenSor Switch, inc.

Toggle Switch controlling the Exhaust Fan. The sensors Green wire
connects to Ground. When the sensor is in the Occupied Mode, the
Exhaust Fan may be overridden Off by the Toggle Switch.

The sensor Green wire connects to ground. The sensor requires several minutes
to warm up.
AREA OF COVERAGE
The PIR collector beams view out horizontally
in a wall-to-wall pattern. The beams will see out
to 20 feet, however, the effectiveness for small
hand or body motions is 10 feet.

10 SECOND GRACE PERIOD
When in Manual On mode, if the sensor times out
and turns off the lights, the PIR detector will remain
active for 10 seconds to allow the occupant to move
and automatically turn on the lights. However, after
10 seconds, the push-button must be pressed to
activate the lights.
