Wiring Sensaphone
A Sensaphone is used to notify the user via telephone, cell phone, or pager whenever the sensors reach the
user programmed temperature alarm limits.
1. Open up the front panel to the 90 deg. position, as shown in Figure 4.5. Make sure the cable supports the
front panel securely.
2. Find a location that is near the controller.
3. Run the free end of the cable to the controller unit.
4. You may extend the cable as needed, but make sure to use an adapter and wire approved by Link4 to
make any extensions (the wire and adapter can be purchased from Link4).
5. Carefully insert the cable through the left most watertight fittings at the bottom of the enclosure. It is easy to
strip insulation and/or break wires when pulling cable. Use UV protected “tie wraps” (typically blue or black),
and do not over-tighten.
Note:
If any splices are needed to extend cable length, make certain they are WATERTIGHT. Water or fertilizer
infiltration WILL cause unstable sensor readings.
6. Keep cables away from interference sources, including high voltage power wiring, inverters, motor
controllers, mercury arc, or sodium lamp circuits.
7. Connect the wires as shown in Figure 4.20.
8. Make sure you test the
Sensaphone by programming a high and low limit and then make the alarms go off
to see if the Sensaphone will contact the right number. After testing remember to unplug the iGrow
1600/1800 before continuing to install other sensors.
9. Refer to the Sensaphone installation instructions for programming the unit.
