Multi Signal Audible Alarm V2

The Multi-Signal Audible Alarm by WMC provides dynamic annunciation and signaling capability to equipment with the power to be heard over the background of the industrial environment. The alarm signal is not limited to a simple preset selection of generic tones, but instead is read from a user configurable sound files that can be any audio the user desires, from voice recordings of instruction and warnings, to any alarm sequence or tone, to full music.  (.WAV .MP3 .OGG .WMA file formats)

The system is powered by 24V  (22-28 VDC). The unit will draw up to 1.25 amps depending on volume output. The inputs are configurable in the config file to be either PNP or NPN type input.

Visual signaling is available allowing indication of alarm state, in high intensity single color, or dynamic Omni-Color.

Communications protocols can be integrated to trigger alarms and visual indication states from networks and serial links. Contact WMC for communication requirements.
