Fixed System Gas Monitors, GfG

4400-C 4- 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.

Features

• 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.

2214018 CS 21 Fixed Gas Transmitter, HFC-23 (CHF3), 30 to 1000 ppm by GfG

The CS 21 transmitter uses the proven chemosorption detection principle for detection of toxic gases, vapors and combustibles. The rapid response of the transmitter provides opportunity to take counter measures and thereby limit damages. The long life of the sensors makes the CS 21 a low-cost solution for your detection needs. A transmitter can be continuously operated for more than 5 years.

Wall mount installation is straightforward. The distance between transmitter and controller can be greater than 500 m. A rugged aluminum casing protects the sensor and electronics from splashes of water and dirt. The transmitter must not be operated in EX-areas. For measurement of combustible gases in the LEL range the gas needs to be sampled by pump. In this case the EX-protection needs to be guaranteed with suitable external components (e.g.flame-protection).

• High sensitivity to a broad range of refrigerants
• Long sensor life
• Fast response

2210-030 Dynagard 25 for O2 Stand-alone System with ZD 21 Transmitter for Detecting Oxygen (O2) and GMA 41B Single Channel Controller by GfG

Simple and Effective

The Dynagard 25 Series accurately measures oxygen levels. The unit offers a local display, a horn / strobe, and a linear 4-20 mA output. The Dynagard 25 Series offers a safe and reliable gas warning system.

Alarm Points

Each alarm can be adjusted separately. The alarm point values can be freely adjusted within the detection range of the transmitter. Every alarm point value can be set to over range / under range, latching / non-latching, or resettable / non-resettable.

Alarm Relays

The controller provides four voltage-free relays for the three alarms and 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.

ZD 21 Zirconia Sensor

The comprehensive electronics allow for easy operation and maintenance and also increase operational safety and accuracy. In less than 2 seconds, the ZD 21 responds to an oxygen deficiency. The sensor has a platinum coating on the inside and outside of the ceramic cylinder. Oxygen is electrochemically reduced at the cathode.

The voltage produced is proportional to the next difference in the partial pressures of oxygen in the reference gas versus the sampled gas. This extremely short response time allows the user the time to take measures to prevent consideable damage.

Features

• Easy installation
• Local display and horn / strobe
• Adjustable alarm points
• On-board relays for external controls
• 4-20 mA output

Advanced Technology

Wherever hazards are expected, the EC 28 transmitter and GfG s proven monitoring systems are the right choice for reliable surveillance. The ATEX-certified design, an integrated, Ex-proof buzzer, and bright alarm LEDs provide the highest safety in hazardous areas by including visual and audible alarms. The gas alarm not only alerts the person in the control room of hazards, but also the person on-site.

Easy handling

Smart sensor technology allows a user to install the transmitter or to replace a sensor within a few seconds just plug the sensor into the transmitter. Adjustments are done directly at the transmitter using touch keys or with the remote control (one-person calibration).

Remote Control RC2

Ammonia and hydrogen are lighter than air. With the transmitter installed close to the ceiling, GfG can provide permanently connected cables with plugs for the remote control, which allow the user to do all adjustments without having to climb a ladder. In addition, one remote control can be used for several transmitters, which helps cut costs and increase efficiency.

The remote control display is always identical to that of the transmitter, making inspection, service, and calibration considerably simple.

The remote control reads the current gas concentration and can be used as an external display.

Integrated Alarm Saves Money on Ex-proof Alarm and Wiring!

The EC 28 D model shows the current gas concentration on-site at the display of the transmitter and also at GfG s GMA controller.

The EC 28 DAprovides additional bright alarm LEDs and a buzzer avoiding costs for a separate Ex-proof horn and an Ex-proof light. You also save money on wiring to connect the controller and alarm devices.

In combination with GfG's flexible control units, the EC 28 provides various possibilities for reliable and cost-effective gas monitoring.
