Chapter 2: Installation
Connecting the Battery
The battery connection is for monitoring the voltage of your boat
battery and it also provides power to the unit in the event of a power
failure. The battery connects to the terminals labelled 12VDC.
If you have the Installation Kit, use the 2-conductor cable supplied.
Otherwise, use a 2-conductor marine grade cable 16-22AWG. Attach
the red wire to the positive (+) terminal on the Boat Remote and the
black wire to the negative (-) terminal. At the other end of the cable
attach the red wire to the positive terminal on the battery and the
black wire to the negative (-) terminal. Refer to Fig. 2.2.
Connecting the Telephone Line
Plug one end of the telephone line cord into the PHONELINE jack of
the Boat Remote, and plug the other end into a modular wall jack.
See Fig. 2.2.
Power Surge Protection
The Boat Remote can be damaged by power surges and lightning
through the telephone line and the 120 VAC power supply. Although
the unit has built-in surge protection, we recommend that additional
protection be obtained for the unit and for any electronic equipment
that is attached to your power supply and telephone lines. Power
surge protection is especially important if your boat is in a lightning
prone area. The ISOTEL Surge Protector Model IB-4 is available
through Phonetics. See Accessory Appendix.
Connecting Accessories
High Water Float Switch
The float switch is used to monitor for high water levels in the bilge.
When choosing a location for the float switch, remember that it’s
purpose is to alarm you when the water level has reached an
unusually high or unacceptable level. Installing the float switch too
low could cause frequent false alarms. We recommend the Rule
model 33, this float switch will trip when the water level has reached
2 1/2" above the base of the switch. DO NOT connect the float
switch to your bilge pump or battery. The float switch need only be
connected to the Boat Remote to operate properly.
