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 consideration 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.

DISCONNECTING THE MODEL 4100
(FOR SEASONAL USE OR STORAGE)
If you plan to employ the Sensaphone as a seasonal watchdog (i.e. only during the winter or
summer months), you must disconnect all wires from the unit completely to avoid damage
to the circuitry when the unit is not in use. If the unit is unplugged but left in place with all
the sensors still wired, the wires act as antennae that draw in any stray “electrical noise”
from such devices as fans, blowers, microwaves, etc.
To preserve your unit during the off season, simply remove the sensor wires at the screw
terminals (you may want to mark the wires to avoid confusion during rewiring), unplug the
unit, disconnect the battery jumper, and store in a safe place.
