Automated Remote Messaging Unit

The ARM-911A responds to public address requirements and Voice Alarm Messaging for small to medium installations. The ARM-911A is a high performance highly versatile stand-alone automated remote messaging controller. This unit is an ideal add on to any existing or new installation PA system and useful to easily initiate code blue paging or lockdown procedures. Up to 4 remote microphones can be connected to the ARM-911A. The microphone can be used for live instant voice messaging. 10 buttons on the microphone station are used to activate any messages. A telephone paging input allows the ARM-911A to be connected to the paging port of a PBX for live telephone paging and message triggering. Each input is fitted with volume controls, High pass filter, equalisers and user programmable input priority settings. 2 auxiliary inputs allow connection to a cordless microphone, background music source or receiving audio from other emergency messaging devices such as fire alarm panels. Ten contact closure or alarm inputs make it possible to obtain external trigger and broadcast pre-programmed message from any remote devices. A built in programmable timer allows for scheduled payback of any of the 10 recorded message and other web-browser control panel up-loadable files. The ARM-911A can also be used for both electronic School bell and automated message playing.
