SECTION IGENERAL DESCRIPTION

The Model PA300 Series can drive one or two 11-ohm impedance, high power (100 W) or low power (58 W) speakers. When two speakers are used, they must be connected in parallel and in phase.

The Tap II feature allows the driver to change the siren sound from Wail to Yelp (or vice-versa) via the vehicle horn ring. Tap II provides especially effec-tive traffic clearing capability. In addition to Tap II, additional alternate sounds can be activated in two other selector-switch positions by pressing and hold-ing the horn ring for as long as the alternate sound is desired. The charts in Section IV of this manual illustrate the operation of these features more fully.

Other special features of the Model PA300 Series include:

• Highdegreeofreliabilityisachieved through the use of integrated circuits and silicon output transistors.

• Controlpanelisilluminatedwith LEDs.

• Newlydesignedprintedcircuitboard provides improved performance and durability under a wide range of environmental conditions.
