POWER PACK CONNECTED TO SWITCH (requires -AX option)
 Some energy codes require Manual On (also called Vacancy) operation where an occupant is required to initially switch on lighting. The sensor then ensures lights are
turned off once the space is unoccupied
 Interfacing momentary switches such as the SWX-801-xx or SWX-803-xx are recommended, however maintained switches can also be utilized
 For momentary switches, the power pack will react on the leading edge of a pulse on the brown input wire
 For maintained switches, any change of state on the brown wire that lasts longer than 0.5 seconds will be read by the power pack as one action
 If no sensor is present, tie power pack low voltage white wire to low voltage red wire
POWER PACK w/ SWITCH SIGNAL FROM EXTERNAL SYSTEM
 Typical for Hold On and Hold Off applications
 BROWN switch input can be activated by external signals +5VDC or higher (i.e. logic high)
 For hold on and hold off applications, switch input can also be congured to activate on logic low
 If no sensor is present, tie power pack low voltage white wire to low voltage red wire

SWX-900 series power packs can supply power to several occupancy sensors and additional secondary relay packs. Following the below formula ensures adequate power will
be available. Note the SWX-900’s relay has already been factored into the formula.

TESTING & TROUBLESHOOTING
TEST MODE
To test unit by toggling the relay, press and hold
pushbutton. LED will turn blue while the button is held.
Release button to return to normal operation.
RESET
To restore factory settings, press and release the push-
button 3 times, wait 2 seconds, then press and release
the push-button 3 times again.
LED INDICATION
 During normal operation, the LED regularly ashes
white as a status “heartbeat”.
 The LED will ash blue once when the unit switches.
 If the LED repeatedly double ashes blue, the power
supply is overloaded. This is probably due to having
too many sensors or secondary relay packs connected.
Remove excess low voltage load from the red wire
until blue double ash stops.
 If the LED regularly ashes blue, both blue relay wires
are connected to power when the relay is open. This
indicates probable miswiring.

Five-Year Limited Warranty.

CONFIGURATION SETTINGS ___________________________________
OPERATIONAL MODES
Standard power packs (model SWX-900) and secondary packs (model SWX-910) close
their relays automatically when a connected sensor signals occupancy. Versions with the
Auxiliary Switch Input option (e.g. model SWX-900-AX) have several additional modes of
operation that are listed below. Auto On/Auto Off (Setting #2) is the default mode.
TO CHANGE THE OPERATIONAL MODE
1Read through the above list and note the number of the desired setting
2Press and release the unit’s pushbutton twice, then wait 2 seconds.The White LED will
blink back the number of the current setting (e.g. 2 = Auto On / Auto Off).
3Press the pushbutton the number times equal to the new desired setting (e.g. 3 =
Manual On / Auto Off). The White LED will blink back the new setting as conrmation.
4New setting is saved after White LED blinks conrmation 3 times. If Blue LED double
ashes at any time, start process over.
LED OPERATION
To disable the LED from continuously ashing white as a “heartbeat”, press and release the
push-button 4 times, wait 2 seconds, then press and release the push-button 4 times again.
RELAY LOGIC
The power pack’s relay closes in response to occupancy being detected. To reverse this
logic (such that the relay opens in response to occupancy), press and release the push-
button 5 times, wait 2 seconds, then press and release the push-button 3 times again.
ADDITIONAL OPERATION NOTES
 When in Auto-on/Auto-off mode, if lights are manually switched off when there are still occupants in a space (to show a presentation for example), they will remain off until either
switched back on manually or the sensor times out once the space is empty.
 When in Manual On / Auto Off mode, if the switch is pressed but no occupancy is ever sensed, the lights will come on for 1 minute and then shut off. If no occupancy sensor is
present, tie the power pack’s white input wire to red (+VDC).
SETTING # MODE DESCRIPTION
2 Auto On / Auto Off Mode* (Occupancy Mode) Lights come on automatically when occupancy is detected and turn off automatically after sensor's time delay expires.
3 Manual On / Auto Off (Vacancy Mode) Lights must be manually switched on via a connected switch, but turn off automatically after sensor's time delay expires.
4 Unused NA
5 Override On / Logic High Lights are held on when auxiliary switch input wire is logic high (5-24VDC). Occupancy is ignored.
6 Override On / Logic Low Lights are held on when auxiliary switch input wire is logic low (< 5VDC). Occupancy is ignored.
7 Override Off / Logic High Lights are held off when auxiliary switch input wire is logic high (5-24VDC). Occupancy is ignored.
8 Override Off / Logic Low Lights are held off when auxiliary switch input wire is logic low (< 5VDC). Occupancy is ignored.
