SA-430-17  Installation and Operating Instructions 

 

 

CP5010A 

08/05/08  

 

This unit is designed to provide years of reliable service under even the worst conditions.  

Many times there may appear to be a problem with the unit when the true problem is in the 

speaker(s) or improper installation.  The following chart shows typical symptoms and possible 

causes. 

A blown amplifier fuse doesn't necessarily mean that the unit is bad.  If a speaker or speaker 

lead is shorted this fuse will blow before the unit is damaged.  Disconnect the SPKR leads and 

replace the fuse.  If the siren emits a sound when in the Yelp position it is OK.  Check the 

speaker(s) or leads for possible shorting.
