Cover Removal
- Remove
the three Philip head screws
located on each side of the
unit. DO NOT REMOVE
THE SCREWS ON THE
BOTTOM OF THE UNIT!
Slide the top cover off of
the unit. This cover can be
removed completely from
the siren unit. Carefully
slide the cover off and set it
aside.
After the cover has been removed, find the location of the option jumpers (see the
diagram below).
Auxiliary Input Polarity
- The auxiliary input (green wire) is normally activated
by applying a positive voltage to the wire. To activate it by connecting it to
ground (negative), move the jumper from the "AUX-POS" pins to the "AUX-
NEG" pins.
