60 Amended: Jan 2014Locating a fault on a loopIf the fault is a short circuit middle or a open circuit on the loop the check auto-config function can beused. This is in the supervisor level on the others section of the display. When this function is usedthe panel will go round the loop from the start until it cannot communicate with a device it will thenshow an open circuit at an address, this will help locate a short/open circuit in the middle of a loop. Ifcheck auto-config shows a fault at the end of the loop but no short or open can be found, the problemmay be a resetting detector, see 'loop voltage drop' above in “Open circuit” Positive/Negative sectionabove. Alternatively run the Intermittent fault search in the high level menu.If an address is suspected as been faulty or dual addressed the test device function can be used tolocate the device. Test device is in the engineer level under testing. When a device is put into test itsLED should light up, two will light up if both devices have the same address. If the tested device is asounder it will sound continuous. Sometimes the faulty device will not respond if this is the case testthe device before the faulty one and the one after the faulty one to help locate the exact device.
