The complete solution for Mechanical Rooms. Monitor up

to 20 sensors for Refrigerant, Toxic and Combustible gases.

The 301EM-20 acts as a controller for up to 20 remote

sensors and suits a variety of gas detection system solutions

for Mechanical Rooms.

Particularly configured to meet ASHRAE 15. B-52 and International

Mechanical Code requirements, the 301EM-20 is commonly used

to optimize gas detection in mechanical and chiller rooms. A full

complement of sensors (including toxic, oxygen, combustible gases

and a full line of refrigerant sensors), horns, strobes and remote

panels provide added flexibility to suit a variety of gas detection

system solutions.
