PAL-AT®
Application

Leak detection controller that can detect leaks for wide range of applications for water, corrosive liquids and hydrocarbons.

Description

A versatile leak detection controller with advanced features that can detect leaks for wide range of applications for water, corrosive liquids and hydrocarbons.

Can operate as a standalone leak detection system, as part of an enterprise solution of multiple networked PAL-AT® systems monitored by PALCOM® software or as an integrated solution with third party BMS systems via ModBus or BACnet.


Features and benefits:


  • Accurate detection of multiple leak locations simultaneously.
  • 24/7 continuous monitoring.
  • FM Global-approved fuel (diesel) detection FM 7745.
  • Cable and point sensor-capable.
  • Relay out-capable.
  • Remote alert-capable.
  • ±1% accuracy.
  • IP52 rated as standard, IP66 outdoor option.
  • Modbus TCP, BACNet, Modbus RTU and Modbus RTU over TCP protocols for third party integration.
  • Built-in intelligence and monitoring to detect breaks and shorts.
  • Heads up display to provide system health status.
  • Comprehensive events and logs stored locally with simple download function.
  • Dust and dirt proof to eliminate false alarm.
  • Customizable security logins to ensure maximum security.
  • Optional Zener barrier panel for intrinsically safe requirements.
  • Hazardous locations rating: Class I, Division 1, Groups C & D, Zone 0 and Group IIB.
  • CE marked and UL listed.


Installation:

Wall mount through holes on back of panel.
