A New Controller for Two-Point Detection

The GC-532R is our new 2-channel gas leak alarm and shutoff controller. It monitors up to two FB-365 gas detectors and controls one automatic shutoff device on the gas line.

It is meant for sites where one detector does not cover the area, for example a kitchen with cooking stations on both sides of the room, but where a larger multi-channel panel is not needed.

What Connects to It

  • Power: AC 220V
  • Detectors: up to two FB-365 (LPG)
  • Shutoff device: one
  • Warning light: AC 220V, connected through the controller
  • External signal: dry-contact input for a signal from another system

Switch off the power before connecting AC 220V. Connect each detector and the shutoff device to the terminals marked for them on the controller.

Where It Fits in the Range

  • One detector: FC-531R
  • Two detectors: GC-532R
  • More detection points: EC-533R and EC-536R
