  • Page 7 INSTALLATION An improperly installed 8410 IP Display Speaker or 8420 IP Dual-Sided Display Speaker could fall from a wall or ceiling and cause serious injury or death. Local building code may require one or more additional safety measure(s), particularly in earthquake prone regions.

  • Page 8: General

    The 8420 IP Dual-Sided IP Display Speaker has all the core components of the 8410 but double. The two-sided functionality of the 8420 is ideal for installation in corridors, large spaces, or hallways for easy opposite-facing visual and audible communication.

  • Page 9: Setup And Installation For 8410 And 8420

    2.1.2 Installation The 8410 IP Display Speaker is designed to fit on a wall bracket. Concealed wiring may enter from the wall into the wiring cavity. Alternatively, surface wiring may enter through a channel from the bottom edge. AL061-UG-GP258410-001-R0 support@algosolutions.com...
  • Page 10 Attaching the 8410 to the wall-mount bracket: 1. Set the 8410 into the wall-mount bracket. 2. Align the holes on the side of the 8410 to the holes in the wall-mount bracket and tighten the four 6-32 mounting screws securely using the Allen key.

  • Page 11: 8420 Mounting & Installation

    8420 IP Dual-Sided Display Speaker 8420 Mounting & Installation Algo’s 8420 IP Dual-Sided Display Speaker is a two-sided SIP-compliant notification device that can be mounted on the ceiling or wall for two-sided visual communication. This is ideally suited for hallways, corridors, or open spaces.

  • Page 12: Making Your First Configuration

    8410 IP Display Speaker & 8420 IP Dual-Sided Display Speaker 1. Set the 8420 into the mounting bracket by partially threading the screws into the holes next to the connector opening and mount the screws through the larger hole of the keyhole slot. Slide the 8420 into the smaller holes to lock the device in place.

  • Page 13: Power Requirements

    A recessed reset button (RST) is located at the bottom of the device below the speaker and can only be used to reset the 8410 IP Display Speaker and 8420 IP Dual-Sided Display Speaker at time of power up. To return all the settings to the factory default for the 8410, reboot or power cycle the 8410/8420.

  • Page 14: Applications

    Multicast Receiver The 8410 and 8420 are ideal for use as multicast receivers. Each alert can be mapped to multicast zones which can be associated with a display on the LCD screens to complement the audio announcements.

  • Page 15: Features

    If VLAN is used, navigate to the Advanced Settings → Network tab to set VLAN options. Important Once the 8410 IP Display Speaker is using a VLAN, you will need to be on the same VLAN to access the web interface.

  • Page 16: Multicast Overview

    An Algo 8301 IP Paging Adapter & Scheduler can be configured with a SIP Page Extension to multicast to the 8410 IP Display Speaker. When called from a phone, the SIP registered 8301 will auto-answer and play the page audio over the 8410/8420 speaker.

  • Page 17: Sip-Activated Visual Notification Alerts

    In addition to audible notifications, the 8410/8420 can multicast visual alerting with the LED flashers. When a call is made to the SIP extension, the 8410/8420 will flash the selected light pattern. Often, the flashers for the 8410 will be part of a hunt group or ring group to flash in conjunction with an audio notification.
  • Page 18 8410 IP Display Speaker & 8420 IP Dual-Sided Display Speaker For SIP TLS, no default public CA certificates are used; only the above .pem file is supported, so this certificate file must be uploaded in order for SIP TLS authentication to occur.
  • Page 19 8410 IP Display Speaker & 8420 IP Dual-Sided Display Speaker Important To verify the server, enable the ‘Validate Server Certificate’ option. This then checks if the certificate that is provided by the server is signed by any of the CAs included in the list of trusted CAs (used by the Debian infrastructure and Mozilla browsers).
  • Page 20 8410 IP Display Speaker & 8420 IP Dual-Sided Display Speaker The ‘Validate Server Certificate’ parameter can also be enabled through provisioning: prov.download.cert = 1 Encrypting SIP and RTP Communication SIP signalling is secured by setting ‘SIP Transportation’ to ‘TLS’ (under the Advanced Settings → Advanced SIP tab).
  • Page 21 8420 IP Dual-Sided Display Speaker Important For a SIP server to validate the Algo device, an additional certificate has to be manually installed on the 8410/8420. To add this user certificate file use a ‘.pem’ filetype extension and have the file named ‘sipclient’.

  • Page 22: Web Interface

    Web Interface Login Figure 1: 8410 Status The web interface requires a password to login to see the device settings. The default password is ‘algo’. This password can be changed in the Admin tab after logging in the first time.

The call will be terminated when the timeout occurs whether anyone is speaking or not. This is useful for situations when someone accidentally forgets to hang up, preventing the paging system from getting stuck in the active state.

  • Page 29: Multicast

    Select the preferred dual-tone multi-frequency (DTMF) detection method. DTMF is a technology used with touch tone phones, best known to users as the sound made when pressing a number key. In the 8410 or 8420, this is used for multi-zone selection, passcode, etc.
  • Page 30 2. Port numbers range: 1 to 65535 3. By default, the 8410 or 8420 is set to use the multicast IP address 224.0.2.60 and the port numbers 50000-50008 Make sure that the multicast IP address and port number do not conflict with other services and devices on the same network.

  • Page 31: Multicast (Transmitter/Sender Settings)

    Multicast Mode (Transmitter/Sender Selected) If Transmitter mode is enabled the 8410 or 8420 will broadcast an IP stream when activated in addition to playing the audio. (Note that the 8410 or 8420 cannot be both a multicast Transmitter and Receiver simultaneously).
  • Page 32 Select ‘Regular’ if solely multicasting to Algo SIP endpoints and/or multicast-enabled phones. To multicast page announcements solely to Polycom phones, select ‘Polycom Group Page’ or ‘Push-to-Talk’. Then, configure the 8410 or 8420 with the ‘Polycom Zone’ (IP Address and Port) and ‘Polycom Default Channel’. Note Always ensure that the multicast settings on all Receiver devices match those of the Transmitter Select ‘Regular RTP + Polycom Group Page/Push-to-Talk’...

  • Page 34: Multicast (Receiver Settings)

    Multicast Mode Multicast Mode (Receiver Selected) If Receiver mode is enabled the 8410 or 8420 will activate when receiving a multicast message. It will mimic the audio stream but use local volume settings (‘Page Speaker Volume’ in Basic Settings → Features).
  • Page 35 If using a Polycom phone as the Multicast Transmitter, a tone may be set for any of the 25 Polycom Groups configured on the Algo device. If an Algo device is used as a Multicast Transmitter, a tone does not have to be set as the Algo Transmitter will provide its own tone.
