Description

The DWOS-1277 is a sensor switch that uses advanced passive infrared sensor technology to detect motion based on emitted heat. It can turn on a load and keep it on as long as motion is detected. The sensor will automatically shut off the load at the end of the selected time delay. The countdown of the time delay starts after the last motion is detected. The sensor switch is customizable with dials that allow adjustment of Time Delay, Detection Range, Ambient Light Level, and a switch to change between Occupancy and Vacancy modes.

DESCRIPTION

• The DWOS-1277 uses advanced passive infrared sensor to detect heat emitted motion. The sensor switch can turn on a load and keep it on as long as it detects motion. The sensor will automatically shut off the load at the end of the selected time delay. The countdown of the selected time delay starts after the last motion detected. The sensor is customizable with dials that can adjust Time Delay, detection Range, ambient Light Level, and a switch to change between Occupancy/ Vacancy modes.

COVERAGE

• As illustrated in Figure 1, The DWOS-1277 has a 180° detection range with a maximum distance of 30’ detection in front of the sensor and 20′ on the sides. For maximum results, the sensor must be properly installed between the height of 4’ to 5’ and away from obstructions such as walls, furniture and transparent barriers like Low-E glass.

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 wires only.

WIRING DIRECTIONS

1. Connect RED wire from sensor to the LOAD wire.
2. Connect BLACK wire from sensor to the HOT wire.
3. Connect WHITE wire from sensor to the NEUTRAL wire.
4. NEUTRAL WIRE IS REQUIRED.
5. Connect GREEN wire from sensor to the GROUND wire.

ADJUSTMENT

• The control panel cover is also the push button on the switch. Remove the push-button cover plate by prying from the bottom of the push-button and pulling outward

• Time dial
  This dial adjusts the time delay. Default position: 15 Seconds (Test mode) Adjustable: from 15 Seconds to 30 Minutes (clockwise)

• Range dial
  This dial adjusts the detection range. Default position: Center at 65%Adjustable: 30% (Position 1) to 100% (Position 4).
  Note: Use the greater setting for larger coverage area.

• Light dial
  The sensor may be adjusted to operate at the desired level of ambient light.

• To do so, turn the dial to point the arrow toward the “-”sign for sensor to detect motion and operate during low light or no light. Point the arrow toward the “+”sign for sensor to operate when there’s more light in the area or even during daylight.

Off/ Occupancy/ Vacancy Mode Switch

OPERATION

Off/ Occupancy/ Vacancy Mode Switch

• The OFF position : Switch is turned off and will not detect motion. The push button will not function.

  ---

• Occupancy position : The load will automatically turn on when motion is detected and automatically turn off when the selected time delay has expired. The push button may be used to manually turn ON/OFF the load and time delay will also take effect.

• Vacancy position: The load will turn on ONLY when the push button is used and automatically turn off when the selected time delay has expired. The push button may be used to manually turn ON/OFF the load and time delay will also take effect. If the time delay has expired and the load turns off, the load will turn on again automatically if motion is detected within 30 seconds.
  NOTE: For DWOS-1277-NL, there is night light behind the Fresnel Lens and it functions as follow:

  • OFF —- The Night Light stays on constantly.
  • OCC —- The Night Light will not function.
  • VAC —- The Night Light will turn on when motion is detected and the load is off. The Night Light will turn off when load is on.

TROUBLESHOOTING

NOTE : There is a 1 minute warm-up time at initial power-up. The load may turn on/off several times.
The Load does not turn On. LED does not flash regardless of motion:

1. Push Manual On/Off Button, if the load turns On; verify that the Range dial is on high.
2. Check the wiring connections. Be sure the NEUTRAL wire is present.
3. Switch may be in Vacancy mode. Select the OCC position on the Mode Switch if “Auto ON” is what’s desired.

The Load does not turn On when LED indicator flashes and motion is detected:

1. Push Manual On/Off Button, if the load turns On; verify that the Range dial is on high.
2. Check the wiring connections. Be sure the LOAD wire is connected.
3. Switch may be in Vacancy mode. Select the OCC position on the Mode Switch if “Auto ON” is what’s desired.
4. Check the Light dial. The pointer indicates the light level the ambient light needs to drop to before the load is automatically turned on.

The Load does not turn Off:

1. Motion may be detected. The time delay constantly restarts its countdown after the last motion detected. To verify proper operation, turn the Time Delay Knob to 15s (Test Mode) and make sure there is no motion (no LED flashing). Tape may be used to cover the fresnel lens while testing.
2. Check for significant heat source emitting within six feet (two meters) such as high wattage light bulb, portable heaters or HAVC vents.
3. Check the wiring. Make sure the HOT and LOAD wires aren’t reversed.

The Load turns on when its not desired:

1. Motion may be detected. The time delay constantly restarts its countdown after the last motion detected. To verify proper operation, turn the Time Delay Knob to 15s (Test Mode) and make sure there is no motion (no LED flashing). Tape may be used to cover the fresnel lens while testing.
2. Check for significant heat source emitting within six feet (two meters) such as high wattage light bulb, portable heaters or HAVC vents.
3. If Manual operation of push-button is desired, select VAC mode on the Mode Switch.
4. If the sensor is installed in a small room, turn the Range dial lower to avoid false or unwanted detection from open window or door.
