Applications

1 Conveyor / Machine Prestart Warning

When audio/visual enunciators (ALUNT_IS) are used an audible and visual (red flashing) alarm is sounded at each alarm site, while ever the controller ‘red’ input is energised. In this mode up to 36 units can be connected at 100mtr intervals on 5mm2 cable to provide ‘overlapping’ performance (as required by AS/NZS 4024) over the entire length of a 3.5klm conveyor; even longer installations may be achieved with higher CSA cable. The alternate (green) state lights a solid green light at each alarm site and (if required) can be used to confirm whole current remote isolation.
