Monnit ALTA Industrial Wireless Dry Contact Sensor (900 MHz)

Meet the Monnit ALTA Industrial Wireless Dry Contact Sensor, a robust solution engineered for reliable monitoring of critical contact closures across industrial environments. Designed to detect when two wired contact points come together, this sensor gives you real-time visibility without bulky wiring runs. Pair it with an external mechanical switch or a contact plate, and you’ll receive instant alerts via SMS text or email the moment the contacts touch or a switch is triggered. With a focus on ease of installation, flexible lead lengths, and seamless integration with Monnit’s cloud platform, the ALTA sensor helps you protect equipment, improve process control, and reduce downtime in manufacturing, facilities management, and logistics applications.

  • Industrial-grade monitoring with wireless simplicity. The ALTA dry contact sensor combines rugged physical design with reliable 900 MHz wireless communication, delivering dependable status updates from remote or hard-to-wire locations without the complexity of traditional wiring. This makes it ideal for securing access points, monitoring machine guards, or tracking the closure status of emergency stops and interlocks in harsh environments.
  • Versatile installation with external switches and contact plates. Use an external mechanical switch or a contact plate to define the monitored contact points. The sensor’s dry contact input detects closure between the two wired points, enabling a wide range of applications—from door and gate monitoring to valve and actuator position sensing—without altering existing circuits.
  • Real-time alerts via SMS and Email. Configure alert rules so you receive immediate notifications when the monitored contacts touch or when a switch is triggered. This capability supports rapid response, improved safety procedures, and event logging for auditing and compliance, all delivered through your preferred communication channel.
  • Lead-length flexibility for clean installations. A variety of lead lengths are available to accommodate different mounting configurations and wiring routes. This flexibility helps you minimize clutter, reduce signal interference, and ensure a tidy, durable installation in equipment rooms, control cabinets, or outdoor enclosures.
  • Scalable, cloud-connected monitoring. As part of the Monnit ALTA family, this sensor integrates with Monnit gateways and the cloud-based platform, enabling centralized monitoring across multiple sites. You can manage sensor fleets, set global alert policies, and view historical data in a single dashboard, empowering better asset management and operational awareness.

how to install Monnit ALTA Industrial Wireless Dry Contact Sensor

  • Plan and identify the monitored contact points. Determine which two wired points will form the dry contact pair and ensure you have the appropriate external switch or contact plate in place if needed. Review the installation environment to select a mounting location with stable signal and accessible wiring routes.
  • Prepare the wiring and components. If using an external mechanical switch or contact plate, mount it securely at the designated location. Ensure the dry contact leads are ready and there is no risk of short circuits or exposed conductors.
  • Connect the dry contact to the sensor. Attach the sensor’s input terminals to the two wires representing the monitored contact pair. Follow any polarity or wiring guidelines supplied by Monnit for proper sensing. Verify that the contact remains open when not triggered and closes when the monitored points touch.
  • Mount the sensor. Secure the ALTA sensor in a protected, vibration-free position using appropriate mounting hardware. Keep it accessible for battery replacement and ensure it is within line-of-sight or within the recommended wireless range of your gateway for best performance.
  • Pair with gateway and configure alerts. Use the Monnit portal or app to add the new sensor, assign it to a device group, and configure notification rules. Choose SMS and/or Email channels, set trigger thresholds (e.g., contact closure), and tailor alert quiet periods if needed to prevent notification fatigue.
  • Test and validate. Trigger the monitored switch to confirm that the sensor reports the event in the Monnit dashboard and that the SMS/Email alerts arrive as expected. Check data timestamps and ensure the signal remains stable during normal operation.
  • Optimize placement and lead lengths. If the alerts are delayed or intermittent, adjust the sensor placement or lead lengths to reduce interference and improve signal reliability. Re-test after any changes to verify consistent operation.

Frequently asked questions

  • What is the Monnit ALTA Wireless Dry Contact Sensor used for? It is designed to monitor the closure between two wired points, enabling remote visibility of contact status for doors, gates, valves, machine guards, and other industrial interfaces. It provides timely alerts to help prevent downtime and improve safety.
  • How do I receive alerts? Alerts can be delivered via SMS text message and/or email. You configure notification channels and rules in the Monnit platform so you receive alerts when the monitored contact closes or when a switch is triggered.
  • Do I need a Monnit Gateway? Yes. The ALTA sensor connects through a Monnit Gateway to the cloud-based platform, which aggregates data, manages devices, and delivers alerts across your fleet. Gateways provide the bridge between field sensors and the internet.
  • Can this sensor be used in harsh or outdoor environments? The ALTA family is built for industrial use; however, the suitability for outdoor or harsh environments depends on enclosure rating and installation. Ensure the sensor is mounted in an appropriate enclosure and protected from direct exposure as required by your application.
  • What affects battery life? Battery life varies with reporting frequency, environmental conditions, and how often the monitored contact changes state. Increasing reporting intervals and using low-power configurations can extend battery life, while frequent triggers will shorten it.
  • How do I configure alerts and manage devices? Use the Monnit online platform or mobile app to add the sensor, assign it to a gateway, set up alert rules, and customize notifications. The platform provides dashboards, event history, and device management tools to support scalable monitoring.
