SYSTEM DESIGN GUIDE
SITE SURVEY
This Site Survey Check List will help to determine the paging
system equipment needed for installations. Photocopy this page
and bring it with you when you visit installation sites. You may
need several copies of this chart for each installation.
Section I –SYSTEM NEEDS concerns the requirements of the entire installation.
Section II – SPECIFIC AREA NEEDS concerns specific areas within the installation.
NOTE: Installations that contain areas with different style environments or
sound levels may require Section II to be filled out separately for each area.
Be sure to make enough photocopies of this page for this purpose.

Designing a system and determining an installation’s requirements are quite simple. After you set up your first system, the
steps will appear logical and soon the process will become routine. However, before you begin designing or quoting a job you will
need some basic information regarding the site and the end-user’s needs. Use the Site Survey Check List below to ensure that
you collect all the information you will need to complete the design of the paging system. When you have completed the check
list, create a bill of material for the equipment you need for the installation’s sound system. Refer to the Easy Design
™
Guide
(pages 17-21), page 67 for 70V systems, or page 69 for 24V systems.
Tools Needed (for Site Survey Check List below)
You will need to bring the following tools with you when you visit the installation site:
• measuring wheel/tape measure • sound pressure meter • calculator
• Bogen Products catalog • Photocopies of Site Survey Check List (this page)
Obtain a copy of the floor plan, or create sketches of any
areas that may require special design considerations (high shelving,
speaker mounting locations, exposed beams, amplifier location, etc.).
A successful paging system depends on more than just understanding the physical requirements of the installation site, it also
depends on knowing which special paging features the user will benefit from and use on a daily basis. These include zone paging,
tone controls, night ringer, feedback elimination, ambient noise sensors, multiple inputs, etc
