  • Prior to contracting with Electro-Motion, we did our own maintenance, which was very little due to lack of qualified staff and budget concerns. We have four diesel units at our various high schools and none were in great operating condition. Electro-Motion came in and provided us with professional services and brought our generators up to full operational capability. We are also considered emergency shelters due to unforseen natural disasters; and we need our generators to support this type of operation.

    Alarms – Secondary Containment and High-Low Fuel

    January 2, 2013

    We frequently receive calls about two types of alarms on emergency generators – Secondary Containment Alarms and High Low Fuel Alarms.  A Secondary Containment Alarm provides an alert anytime fuel enters a secondary containment vessel.  This prompts an investigation into a possible leak in the primary fuel tank so that needed repairs can be made quickly.  The High-Low Fuel Alarm is just as it sounds – providing an alert if the fuel level is too high, creating a possible overflow situation, or an alert if the fuel level is too low, so that the generator tank can be properly filled and ready in an emergency.

    Often these questions arise in response to a visit by the fire department inquiring if these alarms are in good working order and requesting a demonstration.  A comprehensive maintenance program ensures the alarms are checked each visit, at least quarterly.  Onsite facilities personnel should ask their service provider to show them how to demonstrate the alarms so that they are prepared for the question during an inspection.   

    If you have questions or concerns about your Secondary Containment Alarm or High-Low Fuel Alarm, please give us a call (650) 321-6169 or drop us an email - We’d be happy to help.
