Can anyone give me any info about this spot type pneumatic heat detector? Ive been in the alarm business for 35 years and never saw this spot type detector before. Im not in the pneumatic detection business but sure have been exposed to just about everything over the years.
Most unique as you can see and the tubing is housed in a wooden frame. it measures 9 inches in diameter.
