Description

The 8420 IP Dual-Sided Display Speaker provides dual-sided enhanced visual and audible intelligibility for effective communication in hallways, corridors, or large, open environments. The dual-sided design enables audible and visual communication and messaging to be projected down long corridors or hallways in opposite directions.  The combined functionality of the two-sided LCD display screen, speakers, and flashing LEDs enable voice paging, visual or audible alerting, and informational visual content, such as scrolling text messages, visual paging, or graphic images. Two-way communication can also be established through the embedded microphone, so real-time updates can easily be provided to admin staff. When idle, the Display Speakers can display a graphic image, rotate through a variety of images, display a clock face (analog and/or digital synchronized to NTP), or go to sleep.

The primary element of the 8420 is the LCD display screens. With unlimited visual possibilities, the screens can produce scrolling text, flashing announcements, full-color images, or key data points, such as dates and times. Combined with LED backlighting and wide-angle viewing, the visual display screens can be seen from anywhere in a room or along a hallway on either side. Visual displays can easily be customized to complement an audio announcement or bring communication to an audio-less environment.

For audible alerting the 8420 offers similar functionality and voice quality as any Algo speaker, delivering wideband audio (HD voice) for clear voice communication and attention-grabbing audible alerting. An embedded microphone is included to enable ambient noise response and two-way talkback capabilities.

The LED flashers provide additional attention-getting awareness to complement the display on the screen and the audio from the wideband speakers. The multicolor LED can deliver alerts in different patterns and color codes to represent a variety of messages (i.e. flashing red for lockdown).

The 8420 is a SIP-compliant IP endpoint that seamlessly integrates into most leading VoIP communication systems.

A single-sided alternative with a flush-mount installation suitable for classrooms, lecture halls, waiting rooms, and offices is available as the 8410 IP Display Speaker.

Visual Display Screen

The 8420 comprises two 15.6” LCD screens that display identical content down hallways, corridors, and large, open environments. The wide-angle LCD screens ensure effective visual communication can be optimally viewed at any angle from both directions. When not in use, the display screens can be configured to auto-dim during off-hours. With the complete flexibility of the LCD display screens, any combination of images, text, or clock can be presented.

A number of preloaded display options are available, such as lockdown, emergency, weather alerts, etc. However, the LCD screens are fully customizable to allow for communication with specific branding and environmental requirements.

The display clock can be shown as either analog or digital and is synchronized with NTP.

With a highly customizable LCD screen, communication options are endless. Common screen displays include:

• Scrolling text
• Images
• Notifications
• Clock – analog or digital
• Daily messages
• Welcome signs
• Rotating display/slideshow
