The AU-340-P Power Supply is the 3.5 Amp, 24 VDC internal power supply for a SigCom Voice Evacuation and Paging system. Utilizing the AU-340-P will provide a built-in DC power source for most small-end systems. Larger systems may utilize an external UL Listed power supply. The AU-340-P includes three LED indicators for AC, DC and Fault indications and a Common Fault contact for supervision of the power supply and batteries via the AU-360 and AU-380 series amplifier module.

A green LED indicates DC power is available from either the power supply or the batteries. A red LED indicates that primary AC voltage is available. A yellow LED will light if both AC power and a Fault are present. The Fault contact will be in the fault state if the batteries are shorted, open below minimum acceptable voltage or if the AC power has dropped below brownout voltage (90 VAC).

The amplifier is a supervised voice/alarm signaling interface that provides alarm signal tones which may be overridden by voice messages. The amplifier is attached to the reverse polarity bell circuit of a fire alarm control panel. The amplifier, signal generator, and speaker lines are continuously supervised. When a trouble condition occurs in the voice system, it is automatically indicated on the fire alarm control panel.

The microphone is attached to the amplifier and mounted in the cabinet. It provides the system with the ability to generate voice evacuation messages and paging instructions.

The digital message repeater broadcasts a prerecorded message over the system’s speakers upon receipt of an alarm condition. The unit initially broadcasts a “Slow Whoop,” waits for five seconds, then plays the recorded message. On the standard unit, the five-second pause and the message are repeated three times. The message and number of times it is repeated are programmable.

The zone splitter provides a mechanism to separate the speaker wiring configuration into four independently supervised loops, thus avoiding a long, continuous wire run through multiple areas. Separation of the speaker loops will allow selected alarm notification and paging and improve serviceability.

The system is designed to operate from the fire alarm control panel’s power. However, it may be desirable to provide an independent power supply for the voice/alarm signaling system. The optional unit available is a 24 VDC 3.5 amp power supply with an integral battery charger. Batteries are available separately. Minimum requirements are two 7A/H 12-volt batteries.

When approved by the authority having jurisdiction, the remote microphone station provides the system with the ability to have Day-to Day paging capability. When an alarm condition occurs, the remote microphone will be automatically disabled, so as not to interfere with alarm signal messaging.

The AU-DM is a state of the art, microprocessor controlled Digital Message Repeater. Many of the features of the AU-DM are field programmable and are easily accomplished through the use of dip switches. Examples of field programmable functions include the initial delay, number of message repeats, pause between message playbacks and the tone to be used in conjunction with the message.
The voice message is pre-recorded at the factory. A variety of messages are available. In addition, custom messages may be recorded based on a user provided script. The digital message is easily upgraded in the field by replacing an EPROM on-board the AU-DM.

Upon initiation of an alarm condition (polarity reversing bell circuit), the AU-DM enters the message playback cycle. A typical message playback cycle consists of five (5) seconds of the evacuation tone, the first playback of the message, five (5) seconds of the tone, the second playback of the message, five (5) seconds of the tone and the third and final message playback. The evacuation tone will then continue as long as the alarm condition exists.
The playback cycle will be aborted if the alarm condition is cleared before the cycle is completed. Live voice paging using the voice evacuation system master microphone will override the playback cycle. When live voice paging occurs, the message playback cycle ends, but the tone will continue until the alarm condition is reset.
