ARM-911
The ARM-911 is a DSP based audio digital signal processing audio mixer and a digital message player. Up to 4 remote paging stations can be connected to the ARM-911. The ARM-911 can accept independent audio inputs from a telephone paging port, and two (mic/line) auxiliary or BGM input sources. The output is balance audio on a 3 position eurobloc connector. The audio output is variable and features a pad selector with level from -50dB, -10dB and +4dB making interfacing to any type of audio inputs on mixers and amplifiers.
Each input is fitted with volume controls and equalizers. All audio inputs features VOX activation and priority override according to user programmable settings (ideal when using a cordless microphone, or receiving audio from other emergency messaging devices such as fire alarm panels) Ten monitored contact closure or alarm inputs making it possible to obtain 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-911 can also be used for either electronic School bell or automated message playing.
- Direct broadcasting of Emergency Message
By pressing one of 10 instant play buttons, message file can be directly played.
- SD Card Backup
Backup SD card is installed inside so that Front SD card can be copied to the backup SD card.
- MP3 Decoding
MP3 file format is supported.
- Remote Control by Network
Using Network, ARM-911 can be controlled at remote place.
- Remote Control by RS-232C
Using RS-232C, ARM-911 can be controlled at remote place.
- Remote Control by Tel In (DTMF)
Using telephone, 10 front buttons can be controlled and voice can be broadcasted.
- Scheduling by Network
Using Network, scheduled broadcasting can be done.
- Variable Input sensitivity of AUX Input
Using GUI (Graphic User Interface), the Input sensitivity can be selected -50dBu, -10dBu or +4dBu.
- Contact Input
Using 10 Contact Inputs, 10 front buttons can be controlled.
- Contact Output
The contact closures can be programmed as external trigger if any messages and schedaled broadcasting is set
to trigger the contact closure when it activates in web browsing interface.
- Fault Output
NO, NC fault dry contact is provided.
