Stockton Service Ce* <br /> PG&E <br /> MONITORING DOUBLE-WALLED TANKS: (continuation) <br /> 2. If a leak is detected, a "BUZZER ALARM" will sound. The <br /> probe sensing the leak will display a RED LIGHT in the <br /> appropriate channel indicator on the panel. Investigate the <br /> alarm condition. <br /> A. To investigate the alarm, remove the appropriate probe <br /> from the tank. If oil is leaking the probe will be wet to the <br /> touch, feeling and smelling "oily". If the probe is wet to <br /> the touch, but does not feel or smell oily, a water leak into <br /> the containment tank can be suspected. If neither of these <br /> conditions exist, a system malfunction can be suspected. <br /> Reinsert the probe and perform a circuit test. <br /> B. To perform a circuit test, press the switch labeled LIQUID, <br /> located at the bottom right format of the system panel. If <br /> performing properly, both channel indicators will show a <br /> RED LIGHT. If only one, or neither of the indicators <br /> respond, the system is representative immediately. <br /> Emergency Response Coordinator <br /> Mel Byrd <br /> 4040 West Lane <br /> Stockton , Ca 95204 <br /> (209) 942-1566 <br />
