Figure 1 The DA as part of the X-618 system
The procedures of the DA as part of the X-618 Public Address and Voice Alarm system are shown
The DCS sends an audio signal to the DA. The DA then amplifies the signal.
The DA sends an amplified 70V or 100V audio signal back to the DCS, which in turn
distributes the signal to each speaker circuit zone.
The DCS sends a 22 KHz signal to the DA, which monitors the system for faults.
