Multicast provides cost effective scalability using a minimum of SIP registered endpoints, as only the endpoint designated to send the multicast needs to be registered. Devices configured to receive the multicast do not need registration.
Support is available for RTP multicast, in addition to Polycom Group Page, Singlewire InformaCast (part no. 8138-IC). Revolution support will be available in Q3 2020.
Multicast zone paging for up to 50 zones can be configured from a single 8138 strobe light. Zones can be selected one of two ways. One option is to map multicast page zones to individual SIP extensions on the endpoint. Fifty (50) page extensions are available for this purpose. Alternatively, in order to minimize SIP registrations, multicast page zones can be configured in the SIP strobe light as a DTMF key press selection using the dial pad of telephone making the page call.
Alert Notification in Transportation, Education, Manufacturing & Other PA Applications
Together with the Algo 8301 SIP Paging Adapter & Scheduler, a PA system requiring multiple zones with scheduled bells / announcements can be easily configured and synchronized with IP clocks using the 8138 and other Algo IP speakers.
If desired, the 8301 IP paging adapter can also provide audio to a legacy analog paging system via its line-level output, and simultaneously multicast this audio to additional Algo IP endpoints.
IP Visual Ring Alerting
The Ring extension on the 8138 is used for telephone visual ringing / ring alerting. The 8138 will flash when this extension is called. Typically the strobe light will be configured in a ring group to include a telephone(s). The strobe light will flash for the duration of the ring event until the call is answered. Fifteen(15) flash patterns, each with three intensity levels, are available to choose from.
Up to 10 Ring extensions are available to register on a single strobe light, thereby allowing one device to act as a visual alerter for several telephones by configuring different ring groups for each registered Ring extension. Each registered extension can of course be configured to flash a specific color, flash pattern and intensity to effectively distinguish each telephone ring event.
Where audible and visual telephone ring alerting is required, the 8138 can be combined with an Algo strobe light using multicast or a relay.
Emergency Notification Alerting
For notification alerting of safety, security and emergency events there are two activation options available: Dial an Emergency Alert extension or connect a button to the strobe’s relay input.
Up to 10 Emergency Alert extensions are available to register on the alerter, allowing for different types of alerts to be activated when the extension is called (e.g., lockdown, evacuation, shelter, all clear, etc.). The multi-color configuration options of the 8138, in addition to multiple flash patterns and intensities, allow this IP alerter to align with specific alerting events. This capability improves situational awareness and response time.
An Emergency Alert can be configured to activate the alerter for a timed duration. Alternatively, the alert be activated until cancelled. This feature uses a Call To Cancel extension to stop activating the strobe light when desired.
Upon calling an Emergency Alert extension the user does not have to remain on the phone. As soon as the call is made the 8138 alerter will flash as configured. This ensures emergency alerting is simple and efficient from any telephone or device in the UC environment. If the Call to Cancel extension is configured, the same cancelling extension will apply to any of the Emergency Alert extensions registered.
As an alternative option for emergency alerting, any button providing a contact closure, including the Algo 1202 and 1203 buttons, can be wired to the 8138 relay input using a 24 gauge single twisted pair. Two configuration options are available via strobe’s relay input upon button activation:
- Flash and/or multicast an alert.
- Call a target extension and play a tone / announcement.
Power for the Algo 1202 and 1203 buttons is provided by the available PoE from the 8138 IP Coilor Visual Alerter.
