8.1 Sensaphone 1108 CottageSitter Edition

The Sensaphone 1108 CottageSitter allows you to monitor and
check on the status of your cottage or cabin from any cellular or
ordinary telephone. The Sensaphone 1108 CottageSitter also allows
you to turn a device on or off using the 1108 keypad or using your
touch-tone telephone. You can also inquire about the status of the
device during a voice status report.
This Sensaphone contains a relay contact on the rear of the unit (see
Figure 1). The relay contact supports both a normally open and a
normally closed contact, commonly referred to as a “double throw”
relay.
When the Sensaphone relay is turned ON, a connection is made
between the ON and C (common) terminals and the connection to
the OFF terminal is disconnected. When the Sensaphone relay is
turned OFF, a connection is made between the OFF and the C
(common) terminals and the connection between the ON and C
(common) is disconnected (See Figure 1). When the Sensaphone
unit is put in standby mode, the relay remains in its last known
state. If the Sensaphone is completely shut down by removing the
batteries and unplugging it from power, the relay returns to an OFF
state, connecting the OFF terminal to the C (common).
The Sensaphone relay is a low voltage relay. Only voltages less than
30 volts AC 2AMPS, or 30 volts DC 2AMPS may be switched. For
higher voltages, an additional high-voltage relay would be required.
Always enlist the services of a licensed electrician when working
with high voltages.Improper wiring can cause harm to you or
your property.
NOTE: For safety reasons it is highly recommended that
the unit only be used to switch low voltage signals (30
volts or less). If you intend to control higher voltages you
must install the unit in an NEC approved electrical panel
