MONNIT 900 MHz Wireless Contact Closure Monitoring Sensor
MONNIT 900 MHz Wireless Contact Closure Monitoring Sensor is a wireless dry contact sensor designed to monitor the open or closed status of external contacts and switches. It can be used to track alarms, relay outputs, door contacts and other equipment with dry contact signals. By transmitting status changes wirelessly to a compatible Monnit monitoring system, it provides a practical way to monitor equipment and facility conditions without requiring a wired data connection.
The MONNIT 900 MHz Wireless Contact Closure Monitoring Sensor is designed for applications where a physical contact or switch state needs to be monitored remotely. A dry contact input can be connected to compatible external equipment, allowing the sensor to detect changes between open and closed states.
This type of monitoring can be useful when an existing device already provides a relay, alarm or switch output but does not have built-in remote monitoring capability. The sensor can provide a wireless connection between that contact signal and a compatible Monnit monitoring system.
It may be used in facilities, equipment rooms, industrial installations and other locations where operators need visibility of equipment status or alarm conditions.
How it works
- The sensor connects to an external dry contact or contact closure.
- The connected contact changes between its open and closed states.
- The sensor detects the change in contact status.
- Status information is transmitted wirelessly to a compatible Monnit monitoring system.
Why choose this product
Customers may choose this sensor when they need to add wireless monitoring to existing equipment that already has a dry contact output. It can help extend monitoring to switches, relays and alarm contacts without modifying the monitored equipment's main control system.
Benefits
- Supports remote visibility of contact status.
- Can be used with existing equipment that provides dry contact outputs.
- Suitable for monitoring simple open or closed conditions.
- Helps bring equipment and alarm status into a compatible wireless monitoring system.
- Can support monitoring across locations where a direct data cable is impractical.
