Installation
IMPORTANT:
Electronic devices are susceptible to lightning and power station electrical surges from both the AC
outlet and the telephone line. It is recommended that a surge protector be installed to protect against such surges.
Programming

Referring to the diagram in
Installation
, section
B
(above), configure shunt
JP1
to set up the trigger
input for the proper input polarity. For a positive going input, put the shunt on the (
+
) side. For a
negative going input or dry contact closure, leave the shunt on the (
-
) side (factory default).
A. Trigger Inputs
Step 1.
Unsnap the plastic cover
(see

Step 2.
Loosen the screw and ro-
tate the circuit board to the
left, exposing the two
mounting holes in the base
(see
Diagram B
right).
Step 3.
Screw the base to the wall,
etc. using (2) #6 flathead or
sheetrock screws.
