3.3.1. SoniStrip Mounting for Ceiling Installations
The following is an example of an installation for a large area immersive room environment.
Important Note:
For customers upgrading existing MiniTrax systems to work with wireless MicroTrax devices – an
InterSense acoustic timing adjuster (ATA) must be inserted in series with the rails in between the
processor and the first beacon in the chain. The ATA allows users with revision 3.0 rails to use
wireless MicroTrax devices more effectively (improves tracking at close range). New systems
using the revision 3.1 rails do not need this ATA.
Most applications for IS-900 systems are best realized with a ceiling mounting of several
SoniStrips in either a grid-like pattern or a staggered pattern as depicted in Figure 18 below. In
both cases, 6-ft. SoniStrips are mounted to the ceiling using InterSense provided ceiling clips that
attach directly to most all suspended ceiling systems.
The SoniStrips are mounted approximately 2 to 3 feet apart, depending on the ceiling height. For
ceilings that are 8 feet high, mount SoniStrips with 2 ft separation. For lower ceilings, consider
using 4-ft. SoniStrips mounted 2 feet apart. For ceiling mounts from 9 to 12 feet high, mount 6-ft
SoniStrips approximately 3 feet apart and plan on using external power boosters to maximize the
acoustic measurement range of the IS-900.

In Figure 18, the coordinate system is shown from a “top down view”, identical to the default
Constellation Array view used with the InterSense set up software ISDEMO. Each SoniStrip is
wired in sequence from the lower left hand corner of the SoniStrip Constellation Array connecting
to Port 5 on the IS-900 Processor.
Definition of the SoniStrip ID numbers come from the wiring sequence, or “daisy chain”, and IS-
900 Processor port number that is used to connect to the Constellation Array. Here, the SoniStrip
