1.1 INTRODUCTION
The Model 2350 and 2360 series Gas Monitors provide continuous monitoring of Methane (and other Combustibles)
and Carbon Monoxide gas simultaneously in a confined space to provide safety for personnel and to reduce the hazard
of gas explosion. Both models are designed to operate from a -48 VDC power source typically available in telephone
equipment applications. The monitors are designed for use primarily in telephone equipment cabinets.
Model 2350 has one sensor which is factory calibrated to detect Carbon Monoxide at 100 PPM and has cross sensitivity
to Hydrogen and Methane (CH
4
). Model 2360 has both a Carbon Monoxide sensor factory calibrated to 100 PPM
Carbon Monoxide and a Combustible Gas sensor calibrated to 5,000 PPM Methane.
Models 2360-00 (figure 1.1) and 2350-00 (figure 1.2) are designed for installation in a customer supplied three position
electrical junction box.
Features of the Models 2350 and 2360 include:
w Local visual and audible alarms.
