ALTA Wireless Control Units Configuration and Installation Guide

Sensor Overview

ALTA Wireless Control Units feature two separate relay switches, allowing for individual control through iMonnit. The ALTA Control Unit relays can be switched on/off manually through iMonnit or automatically by any ALTA Wireless Sensor notification assigned to a single sensor or group of sensors when a specified condition is detected.

The ALTA Wireless 15 Amp Control Unit has two latching relays that will maintain their position even when the unit is powered off. Once their position is electrically set, they will stay there until they are commanded to change it. This is useful when the relays must maintain a position even when power is lost.

The ALTA Wireless 10 and 30 Amp Wireless Control Units have non-latching relays that will return to their original state when powered off. This can be useful as a failsafe when relays must shut off during a power outage.

Please consider the following recommendations and instructions for a successful deployment when configuring, installing, and operating an ALTA Control Unit.

Settings to Configure

  • Name—Enter a unique name for your ALTA Control Unit to easily identify it in many iMonnit views and notifications.
  • Heartbeat Interval (Minutes)—Set the expected time between communication from the device to the gateway while in the Normal State and without any data-triggering events.
  • Poll Interval(Minutes)— The frequency when the device contacts the gateway to ask if control messages await action. It doesn't create a data message.
  • Relay 1 Title—The display name of Relay 1.
  • Relay 2 Title—The display name of Relay 2.

Installation Steps

Step 1.

Remove the Control Unit from the package. Attach the antenna.

Step 2.

Register the Control Unit in iMonnit. Don't power it on until told to do so in iMonnit.

Step 3.

Determine the unit's installation location. Were commend placing the unit in the location and ensuring it reports to the gateway before final installation. See this article if you're using an ALTA Site Survey Tool to perform a site survey to determine unit installation location.

Step 4.

After ensuring that the unit is communicating with the gateway, mount the unit using the supplied screws or double-sided tape.

Step 5.

Verify that the device isn't connected to power, then connect the control unit's relays to the devices you wish to control.

Connecting the Relays

Each relay acts as a switch on the line for your power source. The relays are, by default, NORMALLY OPEN, so there isn't a connection (lights for the relays will be off to indicate this). See the edit page in iMonnit and adjust your relay settings if you wish for the default state to be NORMALLY CLOSED.

The relay allows the current to pass through, so it will be installed inline on the power wire. It isn't connected to power and ground.

Step 6.

Apply power to the unit and set the conditions in iMonnit that will activate the relays.
