The 301 EM configuration is simple and meets the requirements of ASHRAE 15, B-52, and international mechanical specifications. It is commonly used to optimize gas detection in computer rooms and refrigeration rooms. The complete set of sensors (including toxic gas type, oxygen type, combustible gas type, and a complete set of refrigerant sensors), alarms, strobe lights, and remote panels enhance flexibility and are suitable for various gas detection system solutions.

Compliance with ASHRAE No 15-2001 Mechanical Standard and B-52 Specification ASHRAE and B-52 Safety Standards have been established with the aim of reducing risks and protecting the environment and personnel in the data center as much as possible. Special configurations can be selected, and the 301 EM machine room controller is carefully designed to meet or even exceed these strict standards. In addition to manual fan activation, the VA 301 EM can also be configured with automatic fan, alarm, and strobe activation functions. The latch relay is used for manual alarm recognition, the mute button is used for manually disabling the alarm, the built-in 24V DC output is used for alarm operation, and two fragile glass switch accessories are used for manually activating the alarm to ensure performance.
