HEADSET MODULES
There are 2 different types of Headset Modules for the 3010R Series Intercom system
(Figure 5). The HM-10 is the standard module and is designed for use inside the apparatus
where it is protected from the elements. The HM-10 also has a second connection for
Daisy-Chaining (page 8).
The second type of headset module is the PP-20. The PP-20 is a water and corrosion resis-
tant module for use on the exterior of the apparatus (e.g. the pump panel, the tail-board, etc.).
Listed below are some of the items to consider when choosing the location of the headset
modules:
•
The module should be placed convenient to the user.
•
The module should be placed with the plug facing the direction of exit from the
vehicle. This may help to prevent damage to the headset plug, comm cable or the
headset module itself if the user attempts to exit the vehicle while still wearing the
headset.
•
The headset comm cable should hang clear of obstructions.
•
The module should be mounted close enough to the windows so the user may
look out the window without straining the headset module or the comm cable.
•
The module should be positioned so that routing the CA Cables to the modules
can be accomplished in a neat and orderly fashion.
•
The module should be placed to provide access to the jacks on the module for the
CA Cables. The CA Cable from the intercom will be inserted into the jack
beneath the label on the headset module.
•
If you are connecting two headset modules via a “Daisy-Chain,” allow clearance
on the side opposite the label on the HM-10 for the CA Cable to be routed to the
second headset module (page 8).
