Chameleon Product Information

The Chameleon Audio Visual Notification Module (AVN-1) produces audible and/or visual indication of user-defined system alarm conditions. The module can play soundtracks stored in its onboard non-volatile memory or amplify a signal from an external audio input in response to internal or external alarm triggers. A high-intensity LED also provides visual indication of the alarm condition. The visual alarm can be configured to remain steady on or flash on and off at a user-configured frequency. The high-brightness LED can be factory ordered in several colors, including white, red, or green.

The AVN-1 can store up to three 30-second audio soundtracks. The playback of each soundtrack can be individually triggered via its discrete inputs or via backplane commands from a neighboring module. Audio tracks are stored in standard Waveform file format (.wav) and can be downloaded to the device over its wireless infra-red interface.

When the AVN-1 is combined with the Chameleon Alarm Switchboard Module (ASM-1), they form an ideal replacement for legacy Navy IC/SM alarm panels. The standard IC/SM alarm sound is one of the default soundtracks stored on the unit.

Both the audible volume and LED intensity can be adjusted with pushbuttons on the front face of the device. The current volume and intensity settings are indicated on a pair of ten-element bargraphs. The pushbutton controls can be disabled and the brightness and volume settings can be pre-configured to fixed levels.

The AVN-1 contains sync input and sync output channels that allow coordinated alarming between daisy-chained units (i.e., coordinated soundtrack playback and light flashing).

As with all Chameleon modules, the AVN-1 offers unequaled ruggedness. It is specifically designed for sustained operation in severe environments, including those characterized by extreme shock, vibration, electro-magnetic interference, temperature, and/or humidity. Its fully-sealed enclosure (sealing end-caps not pictured) ensures long-lasting operation in the grimiest settings.
