The Intrasonic Technology Retrofit system is designed to work with most existing
housings. To determine if you can use the existing wall housing measure the inside height
and width of the existing housing. If it measures between 14 1/8 inches to 14 3/8 inches
in width and at least 5 ¾ inches high, you should be able to use the existing housing.
If you find that you can not use the existing housing, you will need to remove the old
housing and install an Intrasonic Technology I1000H Rough-In kit.
Some old systems have the power coming in to a box that hangs from the bottom of the
wall housing that contains one or two transformers. The Intrasonic Technology Retrofit
system does not use transformers. You will need to carefully remove these transformers,
bring the Romex up into the housing for connection to the Intrasonic Technology master.
Note: Do not remove the old transformer housing and if there was a cover you will need to
save it. The cover should be replaced once the Romex is wired to the Intrasonic
Technology wires.
If you are using the original housing, you will need to install the Intrasonic Technology
mounting straps. These come with Retrofit RETRO-M master. Be sure to install them with
the flat side facing the chassis. As closely as possible mount them with the mounting screw
hole centered between the top and bottom. If there are holes available you can use them
to screw the mounting straps to the chassis. But be careful not to mount them too far
towards the back. The mounting strap needs to be no more then 1/2” from the front end
of the chassis. If there are no holes, drill holes to mount the mounting strap.

mounting the left side strap, make sure the left and right straps are level. This will insure that the
master is level when installed.
