Materials Alerting Communicators of America (ACA)
As last reported, ACA planned to ship the first 10 control panels on March 5th.
Due to design problems with the siren control circuitry, they were not able to ship on this date.
Subsequent modifications were made to the controls. On March 10th & lith, a modified control panel and encoder were l
brought to our offices by an ACA Field Engineer. He supplied l
us with information on installation and testing of the siren equipment and also demonstrated the operation of the modified
{
control panel. During the demonstration, the decoder in the control panel failed to operate properly. ACA worked March 12th J
through the 14th to solve the problem, and are presently making
/D another modification. This has delayed shipment of the control pancis. ACA received all of the modified siren motors on March 15th, 3hh O
