FUSES
There are several fuses in this unit that protect it from
shorts, spikes, and other such electrical problems that
may possibly damage the unit.
The HRT is protected internally by a 2 amp self-
resetting fuse. This is not user serviceable, but will
automatically reset once the short is removed.
The entire unit is protected by a 20 amp
automotive type fuse, located on the back
of the unit. If your unit completely stops
working, this fuse should be checked.
Seven additional fuses are located inside
the control box. These fuses protect the
seven high-current light outputs. If only
one of your outputs is not working
correctly, it may be that the corresponding
fuse for that output has blown,
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 fuses (see the diagram
below). Each high current light output is protected with a separate 20A
automotive blade fuse. Check each of these fuses to make sure they are all
working properly, and none have blown.
