Sensorworx Line Voltage Wall Switch Sensors

Overview

Sensorworx wall switch sensors detect movement in the infrared energy that radiates from occupants. Once occupancy is identified, the sensor's internal relay switches power on to the connected lighting. Units can also be configured to operate in Vacancy Mode (e.g., require lights to be manually switched on). If equipped with passive dual technology (PIR/Acoustic), the unit's microphone is enabled to further enhance detection. An internal timer is set to keep lights on during brief periods of inactivity and is reset every time occupancy is signaled by either the passive infrared or acoustic detection technologies. Ambient daylight detection can also be enabled to hold lights off in rooms with sufficient light contribution from windows or skylights.

Installation

Wiring

• For supply connections, use 14 AWG (90° C) or larger wires.
• Risk of Electric Shock - more than one disconnect switch may be required to de-energize the equipment before servicing.
• It is recommended that wiring the unit’s ground connection be done first.
• Unit works both in installations where neutral connection is available as well as installations where only ground connection is present.
• If no neutral is present, remove the white sleeve from the wire & connect the now Green/Yellow wire to ground (see diagram below).
• The White wire (or Green/Yellow wire underneath the removable sleeve) MUST be connected to neutral (or Ground if sleeve is removed) for the unit to operate.
• The all Green wire is just for safety.
• The unit’s two black wires are interchangeable (e.g., one connects to line power, one connects to load).
• After wiring and mounting, install wall plate (not included) before turning back on power at the circuit breaker.

Standard Wiring:

* IF NO NEUTRAL PRESENT, REMOVE WHITE SLEEVE FROM WIRE & CONNECT REMAINING GREEN/YELLOW WIRE TO GROUND

Neutral to Ground Wire Conversion Detail:

* NEUTRAL CONNECTION IS OPTIONAL, CAP IF UNUSED

3-Way Wiring:

Two Sensors in Parallel

• Both sensors must time out for lights to turn off (or both buttons must be switched).
• Recommended for Automatic On (Occupancy) applications only.

WARNING: TURN POWER OFF AT THE CIRCUIT BREAKER BEFORE WIRING

Configuration Settings

There are several settings that can be modified. To change a setting, follow the below steps:

1. Press and hold the push button until blue LED begins flashing rapidly, then release.
2. Tap the button the number of times corresponding to the Function # to be changed (e.g., 2 times for Time Delay).
3. The LED will blink back white the number of times equal to the current setting (e.g., 4 times for 10 minutes). Following a short pause, this blink back sequence will repeat.
4. Interrupt blink back by pressing the button the number of times corresponding to the new setting. (e.g., 3 times for 5 minutes). The LED will blink back white the number as confirmation.
5. To exit and save, press and hold the push button until blue LED changes to white, then release. Unit will blink white twice indicating save was successful. If LED blinks twice blue, an error condition occurred.

Function #2 Occupancy Time Delay Settings

Lights are held on following all occupancy events for the selected period.

* TEMPORARY 5 SEC TIME DELAY, REVERTS AFTER 10 MIN

Extended Time Delays

** EXTENDED TIME DELAYS GREATLY REDUCE ENERGY SAVINGS

Function #3 Operational Modes

Several pre-programmed operational modes are available to accommodate both preferences and applicable energy codes.

Operation Modes Descriptions

• Vacancy Mode (Manual On / Automatic Off): This mode provides increased energy savings but requires the user to initially turn on the lights by pressing the button. Lights can also be switched off manually. Models SWX-103, SWX-104, SWX-113, SWX-123, SWX-124, and SWX-133 default to Vacancy mode.
• Occupancy Mode (Automatic On / Automatic Off): Automatic On and Automatic Off operation. If lights are switched off manually, the Automatic On functionality is disabled for ~10 seconds to allow the occupant time to leave the room before returning to Automatic On operation. The LED will blink white during this period. If during the last 5 seconds of this period the sensor detects that the occupant remained in the space, the unit will stay in a manual on state until the switch is pressed again. Otherwise the unit will return to Automatic On operation and the blue locator LED will turn on. This mode is the default operation of SWX-101, SWX-111, SWX-121, and SWX-131 models. Not available for models SWX-104 and SWX-124.
• Automatic On w/ Exit Time Mode (Automatic On/Automatic Off): If lights are switched off manually, the Automatic On functionality is disabled for a fixed 30 seconds to allow a person time to leave the room. Not available for SWX-104 and SWX-124 models.
• Override Off Mode: Automatic On and Automatic Off operation until lights are switched off manually, at which point Automatic On functionality is disabled until the button is pressed again. Not available for SWX-104 and SWX-124 models.
• Disabled Switch Mode: Automatic On and Automatic Off operation only. Switch functionality to manually turn on/off lights is disabled. Not available for SWX-104 and SWX-124 models.
• Presentation Mode: If lights are switched off manually, the Automatic On functionality is disabled until the space becomes unoccupied and the sensor's time delay expires.
• Disable Sensor (Toggle Switch Mode): The unit will not automatically turn on or off connected lighting. Lighting is toggled only when button is pushed.

Function #4 Ambient Light Override (Photocell)

Sensor will prevent lights from automatically turning on when measured light level exceeds selected setpoint (e.g., ambient light threshold). This value is user selectable (see values in table below) or can be chosen by the Auto-Setpoint function. The unit's LED blinks blue every 10 seconds when lights are being overridden. If ambient light level falls below threshold for more than 45 seconds, lights will switch on. During transition time, the LED will blink blue at an increasingly faster rate. Once on, lights will stay on until occupancy time delay expires, regardless of ambient light level.

Manual Setpoint Options

Note for this function, the value of the setpoint will be blinked back in two alternating digits:

Blue LED = 10's digit (1-9 blinks or rapid blink for 0)

White LED = 1's digit (1-9 blinks or rapid blink for 0)

Auto-Setpoint Selection Details

1. Press and hold button until LED flashes rapidly. Release and press button 4 times. Tap button 3 times to select setting 3 "run auto-setpoint", pause, then exit programming mode by pressing button until LED changes from blue to white. The sensor's LED will flash white twice confirming programming change.
2. The sensor's LED will begin to alternate blue and white for 30 seconds. During this time user should move away from sensor.
3. Lights will then be cycled in order for sensor to calculate the controlled (artificial) light level. This is done by subtracting the light level with the lights off (relay open) from the light level with the lights on (relay closed).
4. A setpoint will then be chosen using the following conditions:
   • If controlled level is less than 3 fc, the application is considered open loop and the setpoint will be set to 25 fc.
   • If controlled level is between 3 and 100 fc, setpoint will be set to that level x 1.25.
   • If controlled level is greater than 100 fc the setpoint will be set to 125 fc.
5. To check auto selected setpoint, press and hold button again until LED flashes rapidly. Release and press button 4 times. Setpoint will be blinked back in two alternating digits:
   • Blue LED = 10's digit (1-9 blinks or rapid blink for 0)
   • White LED = 1's digit (1-9 blinks or rapid blink for 0)

Function #5 Auto On Sensitivity

This setting indicates the sensor's PIR sensitivity when the lights are off. Typically this setting should be FULL, but if reflective surfaces (like windows) are causing false-ons the REDUCED setting should be used. Note that the unit returns to full sensitivity after initial detection.

Function #6 Microphone

Dual technology (i.e. PIR + acoustic) sensors prevent non-occupant sounds from resetting the time delay by dynamically reducing the microphone's sensitivity at specific frequencies. In some environments, decreasing the sensitivity across all frequencies so that lights go off sooner, may be preferred. A unit's microphone can also be disabled (effectively changing sensor to a PIR only version).

Function #7 LED Functionality

By default, the sensor's LED will be solid blue when the unit's relay is in the open/off state. This serves as a switch locator. Once the lights are on, the LED will blink white whenever the sensor detects PIR motion. A unit with dual technology will also blink the LED white when it acoustically detects occupancy. The blue and/or white LED functionality can also be disabled.

Function #8 Factory Reset

Operational Notes

Test Mode

A test mode with a 5 second time delay is provided in order to efficiently perform walk testing. The sensor will blink white on any detected PIR event and blue on any detected acoustic event, although its time delay will only be reset by a PIR event. While in test mode, the blue locator LED also will not be lit when the lights are off (i.e. relay open).

To Put a Sensor in Test Mode for 10 Minutes:

• Press and hold the push button until blue LED begins to rapid flash, then release.
• Press sensor's pushbutton 2 times, then wait two seconds.
• Press button 1 time to select Test Mode.
• To exit and save, press and hold the push button again until blue LED changes to white, then release. Unit will blink white twice indicating save was successful. If LED blinks twice blue, an error condition has occurred.

After 10 minutes, the sensor's time delay will revert to previous saved time delay.

Vacancy Mode

• If sensor is configured for vacancy (manual on) operation, the ambient light override setting will be overwritten to "DISABLED" and any attempted modifications to the setting will trigger an error condition (indicated by double blue LED flash after exit/save). The ambient light override feature (i.e. photocell) can only be enabled when the sensor is in an automatic on operating mode.
• There is a 15 second "grace" period after the sensor times out when the sensor will switch lights back on automatically. After 15 seconds the sensor will revert to vacancy (manual on) operation. The blue LED locator (if enabled) will not come on until this grace period has expired.

Microphone Grace Timer

• As an added safety and convenience feature, a sensor with acoustic detection will keep its microphone enabled for an additional 15 seconds after lights are automatically turned off to enable voice reactivation. The LED will not be lit during this period, but once the 15 second grace timer has expired, the LED will come on solid blue (if locator functionality is enabled).
