Automation Components, Inc. (ACI) creates, manufactures, and distributes building automation sensors for the heating, ventilation, and air conditioning (HVAC) Industry. Dpstar is ACI Authorised Distributor in Malaysia. Our product lines include Temperature Sensors, Relative Humidity Sensors, Current Sensors, Pressure Sensors, Gas Sensors, and Wireless Sensors.

ACI’s most rugged single-zone controller, the LD1000 provides reliable leak detection, preventing facility and equipment damage, costly business outages, and downtime.

What Sets ACI’s LD1000 Apart?

  • Zone leak detection system alarms when water comes into contact with the attached sensing cable or spot detector. It is the right fit for spaces where sensing cables and spot detectors are visible so leaks can easily be located.
  • A supervised system, the controller continuously monitors the cable for leaks, breaks, and disconnects and sends an alarm notification when one is detected.
  • Local alarm annunciation and Modbus integration. Onboard audible and visible alarms and a Modbus output allow the LD1000 to notify users of leaks and faults in real-time and deliver that information directly to a LD5200, LD2100, or a larger BMS system.

Applications

  • Facilities where the sensing cable or spot detector is exposed or leaks can easily be located.
  • Areas that require a more durable, robust, industrial single zone leak detection controller.
