Pre-installation checklist
Installing the Dry Contact Sensor
❶ Before you begin, turn off power to the equipment
we are monitoring.
❷ Identify the type of float switch for the HVAC unit
in the “Wiring Diagrams” section.

Monitoring the R-wire with float switches
wired between the HVAC control board and
the thermostat
❶ Turn off power to the HVAC unit.
❷ Install or locate the existing float switches.

❸ Connect one Dry Contact Sensor wire to the float
switch wire that goes to the thermostat.
NOTE: If the unit has more than one float switch, ensure the Dry
Contact Sensor connects to the last float switch in the series.
❹ Connect the remaining Dry Contact Sensor wire to
the C terminal on the HVAC control board.
❺ The switches on the front of the Dry Contact Sensor
should be set to NC (black) and 24V (orange).
❻ Remove the battery tab from the Dry Contact Sensor.
❼ Using the screws, double-sided adhesive tape, or cable
tie provided, install the mounting bracket to a wall or
pipe near the desired monitoring area, and then
mount the Dry Contact Sensor.
❽ Turn on power to the HVAC unit. If the LEDs are
blinking in a pattern, that means the switches are
configured incorrectly. Please double check the wiring
and switch positions before testing the unit.
❾ Test the operation of the Dry Contact Sensor by
tripping the float sensor and holding it in that position
for approximately two seconds. Ensure the Alert LED
on the Dry Contact Sensor turns on for 3 seconds. If the
sensor remains in the alert state, it will continue to blink
for 5 minutes.

for approximately two seconds. Make sure the Alert
LED on the Dry Contact Sensor turns on for 3 seconds.
If the sensor remains in the alert state, it will continue
to blink for 5 minutes.
Monitoring float switches with
a dedicated alarm circuit
❶ Turn off power to the HVAC unit.

❸ Connect one Dry Contact Sensor wire to the Normally
Opened wire or terminal on the float switch
❹ Connect the remaining Dry Contact Sensor wire to
the C terminal on the HVAC control board.
❺ The switches on the front of the Dry Contact Sensor
should be set to NO (white) and 24V (orange).
❻ Remove the battery tab from the Dry Contact Sensor.
❼ Using the screws, double-sided adhesive tape, or cable
tie provided, install the mounting bracket to a wall or

Monitoring Normally Open or Closed
Dry Circuit (with no power running)
❶ Connect the wires to the dry circuit you want
to monitor.
❷ The switches on the front of the Dry Contact Sensor
should be set to NC (black) and (purple) or NO
(white) and (purple).
❸ Remove the battery tab from the Dry Contact Sensor
❹ Using the screws, double-sided adhesive tape, or cable
tie provided, install the mounting bracket to a wall or
pipe near the desired monitoring area, and then
mount the Dry Contact Sensor.

❺ If the LEDs are blinking in a pattern, that means the
switches are configured incorrectly. Please double
check the wiring and switch positions before testing
the unit.
❻ Test the operation of the Dry Contact Sensor by
placing the sump pump in alert state for approximately
two seconds. Make sure the Alert LED on the Dry
Contact Sensor turns on for 3 seconds. If the sensor
remains in the alert state, it will continue to blink for
5 minutes.
Add the sensor to the
Z-Wave newtork
Connect to the network using Z-Wave SmartStart
NOTE: An Alarm.com account is required for this process.
Power on and add devices one at a time.
❶ Power on the Hub.
❷ Log in to the MobileTech app and find the
customer account.
❸ Add the device using SmartStart and follow the
on-screen instructions.
❹ Scan the device’s QR code found on the box or sensor.
❺ Press the button on the sensor. (You will need to
remove the battery tab if you have not already done so.)
• When the network LED on the sensor turns solid green,
the sensor has been successfully added.
❻ Ensure you see the device on your account. This may
take up to 2 minutes.
Connect to the network manually
TIP: For best results, we recommend having the Hub in the same
room as the dry contact sensor you are adding.
❶ Remove the battery tab from the sensor.
❷ Put the Hub into Add mode. Refer to the Hub
documentation for more information.
❸ Press the button on the sensor to add the
device to the network. When the network LED
on the sensor turns solid green, the sensor has
been successfully added.
❹ Name the device based on its application.
This can be done on MobileTech, the Partner
Portal, or the Customer Website.

Troubleshooting
If the Dry Contact Sensor is not
communicating with the Hub
❶ Press the button on the sensor. The network LED
should turn on and then turn off within a few seconds.
If this does not happen, the Dry Contact Sensor
cannot communicate with the Hub. Follow these steps
to fix the communication problems:
a) Install a Z-Wave repeater between the Hub and
Dry Contact Sensor.
TIP: Any AC-powered Z-Wave device will act as a Repeater and
improve the range between the Hub and the Z-Wave device you
are installing.
b) If the previous step does not resolve the issue, try
deleting the sensor from the network (see next
section) and add it again.
Deleting the sensor from the network
TIP: For best results, we recommend having the Hub
in the same room as the Dry Contact Sensor.
❶ Put the Hub into Delete mode. Refer to the Hub
documentation for more information.
❷ Press the button on the sensor to delete it from
the network. The network LED on the sensor will
turn solid green and then blink to indicate the
device has been successfully deleted.
• The network LED on the sensor will turn solid
green and then blink to indicate the device has
been successfully deleted.
