The sensor will hold the lights ON as long as occupancy is detected. The time delay countdown starts when no
motion is detected. After no motion is detected for the length of the time delay, the sensor will turn the lights OFF.
This button is used to select the operating mode for the FS-555.
• A momentary press invokes the Test Mode.
• Press and hold for 5 seconds to invoke the lamp Burn-In Mode.
• Press and hold for 15 seconds to Override the sensor output.
The LED lights to indicate how long the button is held. Initially, the LED is cleared when the button is pressed. After 5 seconds it will turn
ON for 1 sec, then OFF for 1 sec, and after 15 seconds the LED stays ON.
Test Mode
The purpose of the test mode is to be able to quickly determine the coverage area of the sensor without waiting for a lengthy time delay.
Test Mode is a temporary state that provides a 5 minute test period. During the test period, the Time Delay is only 5 seconds. After
5 minutes the sensor returns to the time delay set on the Time Delay switches. To exit from the Test Mode, push the button again or wait
for it to time out.
Override
To override sensor functions so that the load stays ON, push and hold the button for 15 seconds. Depending on the setting of the
Occupancy Mode switch, the output could be overridden ON or OFF. The LED is ON in a steady state when the sensor is in the Override
Mode. To turn off the Override Mode, momentarily push the button again.
Some lamp and ballast manufacturers recommend running lamps at full output for their first 100 hours of operation. The burn-in function
initiates a 100-hour burn-in period. To start the burn-in process, push and hold the button for 5 seconds. The lamps will stay on for
100 hours continuously regardless of occupancy status. After 100 hours, the sensor returns to normal function. To indicate the sensor
is in burn-in mode, the LED flashes rapidly and continuously for the full 100 hours. To turn off the burn-in mode, momentarily push the
button again.
When the sensor is used with a normally closed relay, the Occupancy Mode Switch can be set for fail-ON functionality, or reverse-
occupancy operation. To use the normally closed relay, wire the lighting load to the NC and COM terminals as shown in Figure 9.
To enable Fail-ON functionality, set the Occupancy Mode Switch to ON and wire the load as shown in Figure 9. In this configuration,
the sensor works normally, meaning that it turns ON the lights when there is occupancy, and turns OFF the lights when the Time Delay
expires. Should the sensor fail, the lights turn ON.
If the switch is set to OFF in the N/C wiring configuration, the operation will be reversed. The lights turn ON when there is no occupancy,
and turn OFF when there is occupancy.
