Multizone Intercoms
Valcom’s multizone intercom systems are designed for applications for two-way communications to multiple rooms or areas. Whether your organization is midsize or large, multizone intercoms systems easily integrate with your existing infrastructure and phone system.
Multizone intercoms are easy-to-use and provide the flexibility to program up to 72 zones of two-way intercom, one-way paging, schedules, automated events, clock synchronization, emergency tones and messages.

Analog
Analog Multizone intercom systems require dedicated proprietary cabling and are often referred to as “legacy”. Dedicated cabling must be homerun from the analog talkback speakers located throughout a building back to the Multizone Intercom Controller. An analog system can be stand alone using a basic 2500 type phone for access or connected to a C.O. line port or FXO. Set-up is manual or programmed with a Windows® based software tool. Changes including speaker audio volumes, zones, etc. require physical and/or cable changes on smaller systems (6 zones or less). For larger systems (24-360 zones), many changes including zones, or groups can be controlled by software, however volume changes must be adjusted on the speakers. Analog systems are often used in smaller buildings with 1-6 zones or larger applications with only basic intercom needs and an average of 48 zones.

IP Backbone / Retrofit
IP backbone / retrofit multizone intercom systems are a combination of existing analog speakers and cabling connected to IP retrofit gateways on existing or new network infrastructures. This type system allows use of existing analog infrastructure / speakers, and provides the advantage of migration to IP control. IP backbone system deployment is much faster than analog and offers the benefit of using software to make changes such as volume levels, zoning, etc. Access to make page announcements can be stand alone phones, Interactive Consoles, as well as FXO, FXS, and SIP. IP backbone retrofit intercom systems also provide the ability to connect IP speaker endpoints that work simultaneously with the analog talkback speakers. This type system is often used when a full IP control is desired and the existing speakers and cabling are in satisfactory condition. IP backbone retrofit multizone intercom systems are utilized in both small and large applications ranging from 8 to over 1,000 zones.

Full IP / SIP
Full IP multizone intercom systems are modern, flexible, easy to install, and utilize new or existing network infrastructures. Each speaker simply plugs into a PoE network port. All communications and power is provided with this single PoE port which makes installation fast and simple. Set-up and programming is software controlled and managed. Making changes is simple and done with the click of a mouse including speaker volume levels, zones, etc. Access can be stand alone 2500 type phones (Valcom IP FXS gateway required), IP Interactive Consoles, FXO, or SIP. A full IP system has no limits on zones and doesn’t require an intercom zone controller. This type multizone intercom system is used in all types of applications including small buildings with a few zones or large facilities / campuses with hundreds or thousands of speaker intercom zones.
