Pre-installation checklist

Installing the Dry Contact Sensor

1. Before you begin, turn off the power to the equipment we are monitoring.
2. Identify the type of float switch for the HVAC unit in the “Wiring Diagrams” section.

Wiring diagrams

Monitoring the R-wire with float switches wired between the HVAC control board and the thermostat

1. Turn off power to the HVAC unit.

2. Install or locate the existing float switches.

3. 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.

4. Connect the remaining Dry Contact Sensor wire to the C terminal on the HVAC control board.

5. The switches on the front of the Dry Contact Sensor should be set to NC (black) and 24V (orange).

6. Remove the battery tab from the Dry Contact Sensor.

7. 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.

8. 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.

9. 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.

Monitoring the R-wire with float switches wired between the HVAC transformer and the HVAC control board

1. Turn off power to the HVAC unit.
2. Connect one Dry Contact Sensor wire to the R terminal on the HVAC control board.
3. Connect the remaining Dry Contact Sensor wire to the C terminal on the HVAC control board.
4. The switches on the front of the Dry Contact Sensor should be set to NC (black) and 24V (orange).
5. Remove the battery tab from the Dry Contact Sensor.
6. 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.
7. 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.
8. Test the operation of the Dry Contact Sensor by tripping the float sensor and holding it in that position 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

• Terminals may be labeled differently or may not appear on the device. Please consult the monitored device installation instructions.

  1. Turn off power to the HVAC unit.
  2. Install or locate the existing switch with an alarm circuit.
  3. Connect one Dry Contact Sensor wire to the Normally Opened wire or terminal on the float switch
  4. Connect the remaining Dry Contact Sensor wire to the C terminal on the HVAC control board.
  5. The switches on the front of the Dry Contact Sensor should be set to NO (white) and 24V (orange).
  6. Remove the battery tab from the Dry Contact Sensor.
  7. 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.
  8. 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.
  9. Test the operation of the Dry Contact Sensor by tripping the float sensor and holding it in that position 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 Normally Open or Closed Dry Circuit (with no power running)

• Terminals may be labeled differently or may not appear on the device. Please consult the monitored device installation instructions.

  1. Connect the wires to the dry circuit you want to monitor.

  2. The switches on the front of the Dry Contact Sensor should be set to NC (black) and (purple) or NO (white) and (purple).

  3. Remove the battery tab from the Dry Contact Sensor

  4. 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.

  5. 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.

  6. Test the operation of the Dry Contact Sensor by placing the sump pump in an 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 network

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.

1. Power on the Hub.

2. Log in to the MobileTech app and find the customer account.

3. Add the device using SmartStart and follow the on-screen instructions.

4. Scan the device’s QR code found on the box or sensor.

5. 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.

6. 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.

1. Remove the battery tab from the sensor.
2. Put the Hub into Add mode. Refer to the Hub documentation for more information.
3. 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.
4. 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.

1. Put the Hub into Delete mode. Refer to the Hub documentation for more information.
2. 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.
