• Wood chisel
• Dry wall saw
You may not need to use all these tools on each install but having
them handy will make the overall installation process easier.
Develop the Job Estimate
It is critical that you determine the complexity of each retrofit
installation prior to developing the job estimate. It is hard to predict all
the unique situations you will encounter in the field. For this reason
M&S Systems recommends you visit each retrofit site prior to
developing a job estimate and ordering equipment. During this onsite
visit it is recommended that you complete the items listed below:
• Determine the model number and manufacturer of the existing
intercom system.
• Count the number of room, patio, and door stations.
• Determine if the door and patio stations are surface or flush
mount.
• Remove the master from the wall to see if any non-standard
installation situations might exist, including:
o Electrical running through the wall housing
o Telephone wires running through the wall housing
o Stud spacing that varies from a standard 16” on center
spacing
o The type of wire used for room, door and patio station runs
(M&S, NuTone or other such as telephone wire) - If you
encounter non-standard wire contact our Technical
Support team at 1-800-366-9422 for assistance.
o A remote transformer
o A remote door chime
The answers to the above information will help you scope, price and
install the retrofit system.
