The AMT­-7 Audio, Monitor, and Tone Generator Card is installed in the DAB­-7 Motherboard of the DAN­-7. The AMT­-7 supervises all the power supplies and batteries that may be connected to the DAB­-7. The AMT­-7 monitors all riser connections, allowing Style 4, Style 6, and Style 7 operation of the analog microphone riser as well as the analog telephone riser. With the addition of the optional DVC­-7 Digital Voice Card, a Style 4 or Style 6 digital microphone riser maybe used.

The AMT­-7 can simultaneously generate three annunciatory tones. This allows an Evacuation Tone and an Inquiry Tone to be generated with the added flexibility of having a third backup tone generator. The tone generators can each generate unique selectable tones. The addition of the DMC­-7 Digital Message Card allows automatic selection and playback of up to 120 pre-recorded messages. All available audio sources can be routed to ASM­7 amplifiers and speaker circuits within the DAN­-7 node. There is no restriction on the audio source to amplifier mapping. Input/Output programming is used to determine the audio source selection for each amplifier.

The AMT­-7 provides a technician-friendly local speaker to help troubleshoot audio configuration and "listen" to any audio source. Each audio source supports a volume adjustment, allowing the audio sources to be balanced. The AMT­-7 provides an auxiliary hard-wired input zone and a Form C relay output. This input and output are available for general­ purpose functions. Jumpers enable the data commu­nication network to be terminated at the last node of the line. Indicators display power supply faults, riser faults, ground faults, and degrade mode operations.
