TROUBLESHOOTING GUIDE TROUBLESHOOTING In case loss of PASSWORD at 3L-SP/AP panel, contact ELSA office for master PASSWORD. Liquid leaked is detected when there is no obvious liquid presence. The possible reasons are as follows (it is highly recommended to replace the affected section): ... -
Page 26: Troubleshooting False Alarms After Installation
TROUBLESHOOTING FALSE ALARMS AFTER INSTALLATION ELSA liquid (incl. water) leak sensing cable is a conductive type of sensing cable. Any liquid or solid materials that are conductive can trigger the alarm accidentally or unintentionally when in contact with the two black sensing wires (i.e.: shorted). Such false alarms can appear in two possible scenarios, such as, Continuous or Intermittent false alarm. -
Page 27: Continuous False Alarm - Possible Scenarios
6.2.1 CONTINUOUS FALSE ALARM - POSSIBLE SCENARIOS: Figure 12: Leak false alarm due to chemical stains The above pictures show residues of chemical (e.g. paint, corrosive liquids) stained on the sensing cables which causes the continuous leak alarm. Recommended Solution: ... - Page 28 Figure 13: Leak false alarm due to the contact with metallic parts If part of the sensing cable touches some metallic parts (e.g.: Bracket/clamp, metal pedestal of raised floor panels, grounding strip, aluminum foils, screws, bolts & nuts, etc.) or even metallic burrs that accumulated around the sensing cables, they can cause false leak alarm.
-
Page 29: Intermittent False Alarm - Possible Scenarios
Figure 15: Cable break alarm due to broken wires Cable dented and wire broken due to heavy objects placed on the sensing cables or sharp objects (eg: worker using pen-knife) accidentally cut through the wire while working nearby. If any one of the wires breaks-off (i.e.: open circuit), there is no way to repair. - Page 30 Figure 17: Leak false alarm due to coiling of excess sensing cable There is a tendency that coiled sensing cable can cause intermittent false alarm. The sensing wires may touch each other momentarily, especially when there are strong wind and/or vibration affecting the sensing cables.
- Page 31 If not possible, then insulate with PVC spiral sleeve wrap or hold-down clip or both If there are still interference from these HV sources and/or poor grounding installation in the building (especially retrofitted old building), then install ELSA supplied ferrite-core filter and AC filter to minimize it.
- Page 32 Please make sure that the laid sensing cable can be physically access and check, in order to have a better opportunity to eradicate the false alarms. If after faithfully going through the above troubleshooting guides, the false alarms still cannot be eradicated, please feel free to contact ELSA for further assistance and advice.
