Section 1. INTRODUCTION <br /> The ER-1200 is a permanentely installed system that continuously <br /> monitors vapors aspirated from the underground areas immediately <br /> surrounding the product storage tanks. The system is highly <br /> capable of sensing indications of leaking gasoline, diesel fuel, <br /> and other types of hydrocarbon based materials. When abnormally <br /> high hydrocarbon vapors are sensed, the ER-1200 will set off <br /> visual and audible alarms. A reset button-is provided so that <br /> the user can silence the audible alarm, but the visual alarm can <br /> only be cleared by authorized service personnel. <br /> The panel is equiped with a printer which records on tape the <br /> vapor levels, line pressure, and other conditions consequential <br /> to the proper and continual operation and manitenance of the <br /> system. This permanent record includes alarm conditions, power <br /> interruptions and even the opening and closing of the panel door. <br /> In the event of an alarm condition, the printer will tell the <br /> user exactly what has caused the condition, and direct your <br /> response accordingly. <br /> In the absence of an actual alarm, the ER--1200 will run contin- <br /> uously without need for supervision or attention. It is perhaps <br /> the simplest and most fool proof method of bringing the customer <br /> into compliance with leak detection requirements. <br /> System Specifications Size: 14" x 16" x 8 5/8" <br /> Weight 52 lbs. <br /> Mounting: Permanent Wall Mount <br /> Power: 111/120 VAC <br /> Sensor: Bulk Semiconductor <br /> vapor sensor <br /> Output Formats: 0 - 225 RAW Scalar <br /> 00-ff RAW Hex Scalar <br /> 0.00 to 1.5% Calculated <br /> concentration. <br /> Sensing Lines: `v" I.D.
