Introduction
The VS4820 Wireless Paging Base Station offers a cost-effective way to implement an urgent wireless communication
solution for commercial applications, such as, emergency mass notification, voice & data paging, 2-way intercom
communication, facility-wide audio/visual alerts and SMS text notifications.
With its built-in database, the VS4820 offers users the ability to program up to 1,000 automatic or manually initiated
events that can wirelessly activate a single or group of:
• Wireless PA speakers for playback of pre-programmed voice messages or live-voice announcements
• Send text messages to wireless LED message boards for highly visible public notifications
• Communicate with facility-wide wireless 2-way intercom stations
• Initiate on-time, schedule-based, break/shift bell alerts for improved productivity
• Activate and control wireless beacon lights for public visual alerts
• Send SMS text messages to cell phones for instant event notification
• Synchronize all on-site wireless analog/digital clocks to one accurate time
The VS4820 provides users with the capability to communicate with Visiplex wireless panic buttons. A received panic
button call can instantly activate a pre-defined event, such as, text messaging, voice message playback, visual alert
activations, etc.
Equipped with a built-in commercial band radio transmitter, the VS4820 is ideal as an all-in-one wireless paging solution.
This solution provides full RF coverage to communicate and activate devices for up to 1,000′. When a longer range is
needed, such as multi-building applications, Visiplex offers medium or high-power radio transmitters/repeaters that can
extend the radio signal range to a multi-mile radius, essentially covering any type of installation.
The VS4820 offers additional features and options, such as, an integrated SMS modem for text messaging and alerts,
dial-in phone access for remote event activation, a serial port for integration with a local building fire alarm system, a
built-in Wi-Fi module for interfacing with a local network, hard-wired alarm inputs and a uniquely designed paging
handset for improved voice communication and privacy.
