Repair and Exchange Program

Our DSA system is a modular design that can be serviced & repaired in the field by your maintenance staff if a problem does arise. Just remove the cover, unplug the DSA module, Install the replacement. Within 10-mins the DSA is back to normal.

We have a repair/exchange module that can be shipped overnight to minimize your down time. Also, if (6) or more units are purchased, we will include one (1) spare module free of charge that can be ready to installed at moments notice, so you will always “Be Heard”.


The DSA is warranted to be free from defects in manufacturing for 1-year from purchase date. Any failure to any part of the DSA will be replaced by CSS, a CSS Service Tech, or by overnight UPS delivery to the client. Warranty is limited to product defect or failure. Warranty does not cover any abuse, misuse, normal wear and tear, flood, fire, or rain damage caused by missing screws. Please Note: CSS does not take responsibility for any non-working message that may have caused damage or accident to person(s) or property caused by a non-working DSA. This system is a tool, all safety announcements are the responsibility of the facilities owner, the operator. CSS will warranty the repairs for 1-year, and the shipping with a repair/exchange unit at no charge. After the warranty has expires a repaired/exchange unit will sent at a flat repair rate charge with overnight shipping.
