Multiple NO. inputs are typically TEMPº ALERTs to monitor the tempera-
ture in several different locations simultaneously.

AUXILIARY TEMPERATURE I ALERT INPUT 4

The auxiliary terminal, marked AUX on the terminal strip, is a dual
purpose terminal. It can function as either a status-only temperature
input, or as a fourth dry contact input. If the AUX input is used as a
temperature input, it is only used in a status report and WILL NOT initiate
a dial out process. If the AUX input is used as a fourth dry contact input,
it WILL initiate a dial out process.
To use the terminal as a status-only temperature input, wire one lead of
the remote temperature sensor (FGD-0005) to the AUX screw and the
other lead to GND. If you use the terminal with a remote temperature
sensor, you cannot attach a dry contact sensor.
To use the AUX terminal as a fourth dry contact input, wire any NO. or
N.C. dry contact sensor to it. The Model 1100 will adapt to NO. or N.C.
sensors when the unit ID number is programmed. The unit will dial-out
with the message "Alert condition four exists." See pages 9-10 for instruc-
tions on how to wire a sensor to an alert input, If you use the terminal as
a fourth dry contact, you cannot attach a temperature sensor.

OUTDOOR WIRING

When wiring sensors outdoors, DO NOT let your wiring run freely in open
air. This will surely damage your Sensaphone® during a lightning storm.
Depending on how far your outdoor wiring must travel, serious consider-
ation should be given to using shielded wire inside a metal conduit. The
shield and conduit should both be connected to earth ground. This will
prevent any lightning induced voltage from damaging your
Sensaphone®.
