The loop tester 620 can be used not only as a continuity checker but also as a tone generator
When it is used as a continuity checker, the 620 can be connected to a closing or opening loop pair and it gives out in the case of an alarm state an unequivocal signal tone
As a tone generator, the device gives out a conventional variable tone, which is connected through the 50 cm long red and black test cable or a conventional 6-pin modular plug
The signal loop function represents an uncomplicated method for capturing the occasionally turning up faults and for remote monitoring the functioning of switches
In the signal storage mode the 620 captures the alarm status and goes on emitting a warning tone till the testing apparatus is reset
The practical, magnetic rear wall makes it possible, to fix the model 620 directly to the control cubicle or at the door
