MONNIT Wireless Dry Contact Sensor with AA Battery Power
MONNIT Wireless Dry Contact Sensor with AA Battery Power is a wireless dry contact sensor designed to detect contact between two wired endpoints and send the resulting status through Monnit's ALTA 433 MHz wireless system. With AA battery power and a 12 inch lead or 3-foot lead, it is suitable for connecting to existing switches, relays and contact devices. It provides a practical option for organisations that need to monitor equipment or contact status remotely without relying on a direct wired connection to the monitoring location.
The MONNIT Wireless Dry Contact Sensor with AA Battery Power is part of Monnit's ALTA wireless sensor range and is designed to monitor a dry contact connection. The sensor detects whether contact exists between its two wired endpoints and transmits the resulting data wirelessly to a compatible gateway and monitoring system.
This makes it suitable for monitoring existing equipment that provides a dry contact output, including switches, relays and contact plates. Rather than requiring the contact point to be located beside the monitoring equipment, the sensor uses wireless communication to send status information from the monitored location.
The exact model listed by Monnit uses ALTA 433 MHz communication, standard AA battery power and a 12 inch lead or 3-foot lead. The supplied product configuration is housed in Monnit's standard AA enclosure.
How it works
- The sensor connects to two wired endpoints associated with a dry contact.
- It detects whether contact is present between those endpoints.
- The detected status is transmitted using Monnit ALTA 433 MHz wireless communication.
- The data can then be received by a compatible wireless monitoring system.
Why choose this product
- Suitable for integrating wireless monitoring with existing dry contact devices.
- Uses AA battery power for the supplied configuration.
- Provides a single input for straightforward contact status monitoring.
- The MNS2-4 version uses the 433 MHz ALTA frequency identified by Monnit for the Asia-Pacific and Australian region.
Benefits
- Helps bring contact status information from distributed equipment into a central monitoring system.
- Can be used with existing switches, relays or contact plates.
- Supports remote monitoring of a simple contact condition.
- The wireless design can reduce the need to run a communication cable from the monitored contact point to the receiving location.
