These products combine nitrogen dioxide
(NO2) and carbon monoxide (CO) detection into an energy saving unit. Diesel
engine exhaust is a common producer of NO2, and gasoline engine exhaust is a
common producer of CO. In accordance with recognized National
Standards the permissible exposure limit of NO2 is 1 PPM and for CO the
limit is 100 PPM. The Brasch Combination Detector utilizes a dual sensor
system that monitors both harmful gases. The easy to read digital
display continuously oscillates between NO2 and CO concentration readings.
As target gas levels increase, contacts are provided to
actuate ventilation equipment and an audible internal alarm will activate if
levels continue to rise. Since ventilation equipment is only required when
levels are elevated, energy costs for HVAC operation are significantly reduced.
The Brasch Combination Detector accepts two sensor inputs and
may be provided with both signals integral (local), one integral and one remote
or both remote. When a remote signal is desired, the Detector is provided
with Brasch Gas Transmitter(s) as required.
