Prestart Alarm Controller

The heart of this alarm system is the power supply / controller (ALSUP_24/48). The controller is DIN-rail or foot mounted in a control cabinet and powers alarm enunciators via a two-wire supply bus. The system is totally down-line powered with no batteries or repeaters. There are several enunciator types, depending on the application and price poin...

Applications

1 Conveyor / Machine Prestart Warning

When used in conjunction with AL24X2O / AL24X3O alarm units, a two tone audible alarm is sounded at each alarm site, while ever the controller ‘red’ input is energized. With the 24V output model, up to 55 units can be connected at 100m intervals on 5mm2 cable to provide ‘overlapping’ performance (as required by AS/NZS 4024) over the entire length of a 5.5km conveyor. Greater distances and more alarms can be covered with the 48V version.
