Smartel Tank-Check RF-⁠431 Compressor Failure Alarm

HVAC Number: 4575310

Tank-Check RF-⁠431 Compressor Failure Alarm is an easy-to-install and multi-purpose wireless device failure monitor that is designed specifically for monitoring the operation of compressors in wastewater treatment systems. The alarm’s vibration sensor detects unwanted shutdown of the device and wirelessly notifies the indoor unit when the monitored device has been off for 2 minutes or 45 minutes continuously. The device-specific delay is programmed during the manufacturing process, so remember to indicate your choice regarding the delay when ordering the product. The range of the strong wireless LoRa connection is up to 100 meters. Battery life up to 10 years. The RF-⁠431 series models have two alarm transfer relays for, for example, 4g or 5g modems. One transfer relay is for compressor shutdown and the other for loss of wireless connection between the indoor and outdoor units of the device failure monitor. Made in Finland. 24-⁠month warranty.
