INSTALLATION OF TRACKER WITH SENSOR ALERTS
Each SPOT HUG Tracker comes with four (4) Sensor Alert inputs. These
Sensor Alert wires can be attached to sensor devices in order to monitor
high water, battery level, door opening/closing, and other equipment
that the user chooses. Sensor devices are not included with HUG but
are available as accessories at marine electronics dealers and
findmeSPOT.com. An additional fee is required to receive alert
messages from any monitored equipment.
1. Ensure the monitored device is within the voltage range of:
9.7-37.0 volts.
2. Remove appropriate fuses in the device to be monitored to avoid
potential damage to equipment and electrical shock.
3. If using Sensor Alerts, place the Tracker where the weatherproof Sensor
Alert wires can be easily accessible. Follow the sensor manufacturer’s
wire length and application specifications.
4. Attach the Sensor Alert wire to the appropriate contact and seal the
cable opening with the provided o-ring to prevent water intrusion.
SPOT HUG USER MANUAL
An OPEN contact doesn’t have electrical voltage
passing through until a relay circuit is made.
When the Tracker senses an electrical voltage,
the OPEN Sensor Alert is activated, and the
notification to the contacts commences. Below
are application examples:
• High Water monitoring
• Low battery voltage
A CLOSED contact requires a steady minimum
voltage passing to the sensor so that if the
circuit is broken, the notification to the contacts
commences. There will be a 30 second delay
before sending the CLOSED contact message.
Here are some examples of applications where
this can be used:
• Cabin door monitoring. When door opens, the
circuit is broken.
• Anti-motor theft
• Power Monitoring. When power to cabin is off,
the circuits break.

To accommodate as many sensors as possible, HUG can operate with
accessories that require “OPEN” or “CLOSED” circuits.
