Using Speaker Selectors with IM
Volume Controls
Although IM controls provide volume and on/off at
the volume-control location, they do not give you
central control of speakers playing throughout the
house. Speaker-selection systems give you central
control, but some speaker selectors have non-
defeatable impedance-protection circuits. Combining
IM controls with such a selector will reduce your
maximum volume substantially. To solve this problem,
specify a speaker selector with a defeatable
protection circuit (JobSite models S-4 or S-6). Then
keep the protection circuit off at all times.

INSTALLATION
1. Identify the Speaker wire and Amplifier wire. Label
the wires for future reference.
2. Strip 1/4" of insulation from the end of each wire.
Tightly twist the end of each wire until no frayed
ends remain.
3. Locate the snap and lock
connectors and remove
them if they are plugged
in.
See figures 5.
4. Use a small flathead
screwdriver or your
thumb to raise the
locking tabs, exposing the holes on the connector.
5. Insert wire into the appropriate hole and snap
down the locking tabs.
