The Hussmann Interface Module may be operated
from either battery power or from a 120V/12VDC
transformer. When using the transformer, connect
Module before plugging in the transformer. The
startup screen will automatically appear.

When battery operated, the Module will shut down
if the key pad has not been used for three minutes.
When a transformer is used, the hand held module
will beep and remain on.
If the battery is too weak to function, the menu
screen will become faint or not come up at all. If
the battery is completely without power, the han
held module will beep and show an alar
message. There is also a Low Battery mess
that appears at the Main Menu for Protocol™
Regardless of the power source, if Protoc

beep will sound and a COMM ERROR me
appear. If the Protocol™ system is with
the hand held module will beep a
ALARM message.
