The LEDs, Dipswitches, jumpers, and terminals functions are described
herein.
LEDs Indication
LED Description
Indicates communication status between the Power
Supply and the Main Panel.
On: Normal communication with the Main Panel.
Off: No input power
PS (Power Supply
Communication)
Flashing: Bus communication failure, system in
installation mode or PS dipswitch 4 is OFF.
Indicates communication status between the SMPS UO
module and the Main Panel.
On: Normal communication with the Main Panel.
Off: No voltage power
UO
(Utility Output
Communication)
Flashing: Bus communication failure, system in
installation mode or UO dipswitch 4 is OFF.
Indicates an actual/potential (calculated) overload.
On: Total current consumption from the AUX and
BELL/LS outputs exceeded 3A (power consumption
from both outputs will be disconnected).
Off: Normal current draw
OC
(Over Current)
Flashing: The SMSP detected a potential current
overload when calculating the total value of real current
consumption from the AUX output and expected current
consumption from the BELL/LS output.
NOTE:
To calculate sounder’s current consumption, the Sounder must be operated at
least once (recommended to be performed
upon installation completion).
