turn the relay on
or off.
Is the relay scheduled using the
“Photocell ON/OFF” or “Photocell and
Schedule ON/OFF” scenarios?

Remove the photocell wires or
connector and jumper from Red to Red.
Do the relays turn on/off?
Note: If using the “Photocell and
Schedule ON/OFF” remember to
adjust the clock time to be within your
occupied times before doing the jumper.
No – Call tech Support
Yes – Verify the LV wiring is not
shorted and that the photocell is
operating correctly on the roof.

I go to enter my

and I get the “You
are attempting to
enter a ON/OPEN
time that happens
after the OFF/Close

I need to remove
a sensor from the
system.
Once a sensor has been connected to
a relay driver or group switch card low
voltage input, the input will remain in
the sensor mode even if the sensor is
removed.
To restore normal operation:
1. Remove the sensor wiring from the
panel input.
2. Turn the associated relay or group
off using the red override button
corresponding to the input where the
sensor had been connected.
3. Momentarily jumper the white and
red terminals.
4. Does the relay/group turn on?
No – Call tech support
Yes – Normal operation is restored.
The input is configured for
standard low voltage switches.
