Consider this
As concern for crisis preparedness grows, K-12 facilities often
require both an emergency notification system and a
bell/clock/intercom system. A cost effective approach is
selecting an emergency notification system that also offers all
of the functions of a bell/clock/intercom system.
Benefits of this approach include:
1) Labor savings. Stand-alone emergency notification
systems, even supervised systems, must be tested
periodically to verify operation. By utilizing the system
daily
for
intercom
and
general
announcements,
operational testing requires little or no additional effort.
2) Significant cost saving:
a. Using speakers, visual messaging LED signs and
core equipment for both emergency notification and
daily intercom/paging saves on equipment and
infrastructure costs
b. Installation cost to install one comprehensive
system will be less that installation cost for 2
separate systems
3) One system results in less maintenance.
4) One system results in less training.
5) Daily use means that periodic refresher training is
unnecessary.
The minimal information required to design a school intercom system is: Is this a new or retrofit system?
How many classrooms?
Are call buttons required in the classrooms? How many offices will need an intercom speaker?
What type ceilings are in the different areas? Specifically, are they 2 foot wide drop ceiling?
How many outside horns do they need?
How many speakers and what type will be required for other areas like the cafeteria, gymnasium and auditorium.
How long is each hallway and how high are the ceilings in the hallways.
In addition to this minimal information, a much better design requires the following info: 1) Which classrooms, hallways and other areas will connect to which IDF, or to the MDF.
You can determine this by looking at the prints, picking logical IDF locations and assigning the classrooms, offices and common areas to each based upon logical wire routing.
2) Any and all locations that will require clocks – and what type of clocks they want. 3) How the school would like to zone the hallways. This could be anywhere from a single
zone for each hallway to a single zone for all hallways.
4) Any other “special” requirements (door unlock, VoIP distributions, CD player, local sound reinforcement for the gym, etc)
The following questionnaire may be used as a guide in
determining this information
www.ValcomES.com 5614 Hollins Rd. Roanoke, VA. 24019 Page 5 of 34
When designing a public address/intercom system with limited information such as speaker & clock counts, speaker & clock types and the total number of zones for each area, you have to make assumptions. Assuming that all of the control equipment will be physically located in one location (MDF) will typically result in a less than ideal design.
The diagrams above represent designs with one zone, two zones and six zones respectively with all of the control equipment located in the MDF. Determining the equipment lists for these would be very simple, however, since all speakers and clocks are being powered from the MDF, your installation costs would increase due to the need for more and often heavier gauge, cabling.

A better design would involve knowledge of each IDF’s required speaker & clock quantity, speaker & clock type and zone count. This way, it’s possible to design so that control & support equipment may be selected on a “per IDF” basis.
This reduces cost by minimizing required cable gauge and the number of MDF distribution cables.

Sometimes analog designs involve using Ethernet to distribute audio. This may be accomplished by using VERCA cards, VECPU6-EXP cards, VoIP audio gateways, and/or IP speakers. If the design has only one zone per IDF, as shown in Figure 7, then we’ll need to know how many IDFs will be involved, and the quantity and types of speakers & clocks that will be connected to each.
If the design involves multiple zones per IDF, as shown in Figure 8, then you will need to know how many IDFs will be involved, the quantity and types of speakers that will be connected to each and how many zones each IDF will serve. It’s common to have both single zone IDFs and multi-zone IDFs in the same design.
Figure 9 Figure 10
If a design is fully IP based, meaning every speaker and horn is an endpoint on the network, then you just need total speaker counts per type. Full IP systems are, by far, the easiest type to design and implement.
If a design is IP based, but involves audio gateways to analog speakers, then the same questions will apply:
If the design has only one zone per IDF, as shown in Figure 9, then you need to know how many IDFs will be involved, and the quantity and types of speakers that will be connected to each.
If the design involves multiple zones per IDF, as shown in Figure 10, then you simply need to know how many IDFs will be involved, and the quantity and types of speakers that will be connected to each and how many zones each IDF will serve.

School System Questionnaire
Here are some guidelines for speaker selection:
Ceiling speakers spaced at twice the ceiling height provide the most even sound coverage.
Areas with 2' wide drop ceiling - use lay In ceiling speakers spaced at twice the ceiling height.
Areas with concrete ceilings - use square surface mount ceiling speakers spaced at twice the ceiling height or wall speakers spaced 20 feet apart.
Any area with 1 or 2 speakers may be talkback (it may cost less than one way if the zones are available).
For gyms and outside, use 5-Watt horns (one per 10,000 square feet).
Areas that may get wet should use horns. Smaller areas that require horns may use Flex Horns.
Cafeterias with 2' wide drop ceiling - use lay In speakers spaced at twice the ceiling height. Otherwise use 5 Watt horns (one per 10,000 square feet).
How many classrooms?
How many classrooms will require call buttons? How many classrooms will require a new speaker?
What type?
If ceiling speakers, what type ceilings does the school have?
If speakers exist, what type are they?
What correction protocol do they use?
Does the school need new clocks? Quantity required?
Would the school like a large display for the office area to indicate incoming calls?
Would the school like to add a microphone for general one-way announcements?
Would the school like a Program Distribution Panel to simplify music source adjustment, provide command switch inputs for emergency tones and provide a user-friendly microphone input?
Does the school want the system to control Electric Door Locks? If so, how many?
How many vacant loop start line ports are available on the school's telephone system?
_______ Ports _______ System will be stand-alone
In the case of retrofits, is the school using the current intercom to control their media retrieval system? If so, a new media retrieval system will be required.

If your VECPU5 design will incorporate VETCM, XPETCM24 or VETCS Station cards located in Ethernet accessed remote IDFs, the MDF and each Remote IDF (RIDF) will be set up to provide between 24 and 360 zones each. The sum of all zones must not exceed 360. Use this chart to determine which increments of 24 zones will originate from the MDF and each RIDF. Also note if the range of stations will be one-way only, talkback only, or a combination of one way and talkback. Copy the chart as required to assign each
zone (station) to either the MDF or to a RIDF (see example below). We suggest that you review the system organizational chart shown at the end of this example prior to reviewing the 4 example worksheets.

Ethernet Based School Intercom Systems
Ethernet based intercom systems are also known as Full IP Intercoms. If these
systems include analog speakers and other non-IP equipment connected to end points they are referred to as “hybrid” systems.
Analog speakers, clocks and other non-IP equipment may require AC Power and or space for power supply or other support device installation.
Ethernet Distribution Points, known as EDPs, allow users to define locations where amplifiers for 25-volt speakers, power supplies for One Way Self Amplified Speakers, equipment racks and any equipment required for correcting wired clocks will be installed. For your convenience, EDPs should be provided with names representative of their physical location.
All system EDPs will contain end points that interconnect via POE switch ports on a fully multicast enabled, switched 10/100MB LAN or VLAN.
Ethernet based intercoms that do not feature wired clocks or non-IP (analog) speakers only require a single EDP.
In Ethernet Based Intercom Systems, multiple locations are interconnected via an Ethernet network.
Ethernet Distribution Points must be added for each combination of endpoints that will share a common location for locations where amplifiers for 25-volt speakers, power supplies for One Way Self Amplified Speakers, equipment racks and any equipment required for correcting wired clocks will be installed.
There are a variety of system gateways are available for interface between the VoIP and analog portions of your design.
