Obstruction Obstruction
Adding Remote Motion Sensors
Situations that would need remote sensors to be connected to the Flex-
Stat include:
• Areas too large for adequate coverage by the FlexStat’s built-in sensor.
• Areas with obstructions that block sensor coverage.
• Use of FlexStat models that do not have a built-in sensor.
Remote motion sensors can be connected to one of the FlexStat’s avail-
able inputs. (Custom programming is required.) Multiple remote sen-
sors with dry (relay/switch) contacts can be wired in parallel to monitor
a variety of dierent zones.
An example Control Basic program (for BACstage or TotalControl) that
turns occupancy override on from remote sensors is:
IF AI2 < 1 THEN START BV40 : REM START EXTERNAL OCC
SNSR BV IF INPUT IS SHORTED
IF AI2 > 1 THEN STOP BV40 : REM STOP EXTERNAL OCC
SNSR BV IF INPUT IS OPEN
IF BV40 AND NOT BV1 THEN START BV2 : REM IF EXTER-
NAL OCC SNSR BV IS ACTIVATED AND FLEXSTAT IS NOT
IN OCC, START OVRD MODE
NOTE: The application must have one unused input. Input #2 is used
in this example and assumes Normally Open relays/switches
in the remote sensors. In such a case, the input pull-up resistors
should be set to 10K ohms, and SNSR2 in the Application menu
must be set to NOT USED.
NOTE: To trigger the occupancy override, the remote sensor contacts
must stay closed for two seconds or longer.

the time to less than 0.5 hours

trol to change AV16’s present
