The "
BELL" output will 
shutdown if the current 
exceeds 3A.
AUX Power 
Refer to transformer requirements on page 2 for 
Aux. Power Output. To connect additional wiring to 
auxiliary power, use the red (+) and black (-) 
keypad connectors. Auxiliary power will shut down 
if current exceeds 1.1A. If the auxiliary output is 
overloaded and is shut down, you must 
disconnect all loads from the output for at least 10 
seconds before reconnecting any load back to the 
auxiliary output.
This equipment must be installed and 
maintained by qualified service 
personnel only.
For UL and C-UL warnings, refer to 
the UL and C-UL Warnings section at 
the back of the Reference & 
Installation Manual.
The sum of the current drawn 
from the BELL and AUX must be 
limited to 1.3A (40VA transformer 
strongly recommended). 
Exceeding this limit will overload 
the panel power supply and lead 
to complete system shutdown.
