LN-ALM23T Smart Alarm System

LN-ALM23T Smart Alarm

Independent Backup Power Design. The Ultimate Line of Defense for Your Farm's Climate.

The LN-ALM23T is an independent smart alarm device engineered for high-demand farming environments. Operating entirely independent of the main climate controller, it features a built-in high-capacity rechargeable battery pack. Even during total grid failures, it maintains critical temperature monitoring and executes power outage alarms seamlessly.

Beyond high/low temperature warnings and direct audio-visual siren driving, it is equipped with a 3-channel independent emergency ventilation control system. Upon detecting extreme heat, the alarm overrides the main system, force-starting backup fans for physical cooling, minimizing production risks.
