The construction is made of weighted ABS material and finished with an acrylic top panel. The buttons are integrated using the capacitive touch principle without any mechanically moving parts. Selection & status LED’s are integrated below the acrylic surface, giving an indication of the selected zones and databus status. Besides the zone selectors, quick operation is allowed through the Select & Clear all buttons, while the push-to-talk (PTT) button should be pressed during the announcement. An integrated chime tone is heard before any announcement. Announcements can be made to the integrated pipe-neck microphone with a cardioid pickup pattern which can be tilted to the desired angle. The microphone should be connected to the matrix system using the fixed cable with a length of 2 meters. The distance can be extended to a maximum length of 300 meters, using standard CAT5E (or better) twisted pair cabling. Cascading of multiple paging stations is made possible using the priority-based (user-configurable) databus, when using additional junction boxes ARJ03P or CP45ARJ.
