4100-C Single Channel Controller Panel by GfG

The 4100 one-channel and the 4-channel 4400 gas warning systems offer safe and reliable gas detection.

Alarm points

Each alarm can be adjusted separately. False alarms are eliminated with the adjustable alarm delay. The alarm point values can be freely adjusted within the detection range of the transmitter. Every alarm point value can be selected to be latching / non-latching or resettable / non resettable.

Alarm relays

The controller provides four voltage-free relays for the three alarms in addition to one fault warning. The relays may be used to control additional alarm devices like lights or horns. They can even prompt specific counter measures to prevent or limit dangers from gases or vapors.


  • Complete 1-to-4 channel controller / gas monitoring system
  • 110 VAC or 24 VAC
  • Case-mounted horn / strobe
  • Security lock
  • Slim-line design

Additional features

The 4100 control panel stores peak values and offers an additional 4-20 mA output. The 4400 control panel offers the ability to connect up to 4 transmitters and comes standard with an additional 24 VAC output for solenoid control.
