The AN150Q is a new and improved, drop-in-replacement version of our AN100/AN125 panel mount, pre-programmed speakers. The 9-30VDC unit with quick-connect blades is capable of playing 3 separate messages (programmed at the factory) for a combined recording time of up to 3 minutes of stored sound. Messages are then played using input logic (1-0, 1-1, 0-1). In addition to increased recording time, multiple messages and better sound quality, the unit also features non-polarized input terminals. This provides a more convenient way to deliver voice instructions from a unit the size of a standard piezo alarm.
