• <br />The Leak Alert System <br />Introducing Leak Alert, a highly <br />reliable, state-of-the-art system for <br />cccnntti_n�suis in�nitorin of <br />De - <br />un eerground storage tanks. De- <br />signed and developed by Universal <br />Sensors & Devices, this exciting but <br />economical new electronic system <br />provides both visual and audible <br />warnings of leaking fluids and/or the <br />vapors often generated by leaking <br />fluids. <br />PROBE <br />POWER <br />INDICATOR <br />PROBE <br />ALARMS <br />kVA <br />CONDUIT FOR <br />PROBE CABLES <br />System Features <br />■ No moving parts; noncorro- <br />sive sensor materials for <br />long service life. <br />■ Compact sensing probes <br />with flexible cables; oper- <br />ate in double -walled steel <br />or FRP tanks, wet or vadose <br />zone monitoring wells. <br />■ Simple installation; probe <br />Fan easily be removed for <br />inspection or calibration. <br />■ Models available to moni- <br />The Leak Alert System offers two <br />types of sensing probes: (1) a thermal <br />element capable of detecting the pre- <br />sence of any liquid, and (2) a metal - <br />oxide -semiconductor (MOS) sensor <br />that recognizes the prese—ne of most <br />combustible and organic gases. A <br />single alarm panel will work simulta- <br />neously with both types of sensors — <br />up to 16 channels in all, depending <br />on Leak Alert model selected. <br />NEMA 4 <br />ATHER PROOF <br />ENCLOSURE <br />VIEWING <br />WINDOW <br />MASTER VISUAL <br />ALARM <br />AUDIBLE ALARM <br />TAMPERPROOF <br />ENCLOSURE <br />SEAL (OPTIONAL) <br />AUDIBLE ALARM <br />DEFEAT SWITCH <br />CONDUIT FOR <br />AC POWER, RELAY <br />CONTACTS,& ANALOG <br />SIGNAL OUTPUTS <br />for up to 4.8 or 16 sensors per <br />alarm panel. <br />■ Field adjustable alarm set - <br />point for background vapor <br />screening. <br />■ Built-in audio & visual <br />alarms. <br />■ Auxiliary relay output for <br />remote control. <br />■ Optional analog output for <br />recording or control instru- <br />mentation. <br />
