Gas Alarm GX-D2

GX-D2 CO₂ Alarm: Flexible Ventilation Reminder with External Sensor for Perfect Air in Schools & Offices

The best air measurement is the one that happens right where people are. The GX-D2 from Elektrotechnik Schabus GmbH & Co. KG makes exactly that possible.

Simply plug the device into a power socket, place the external NDIR sensor flexibly near the floor or higher up (depending on the desired sensitivity), wait 3 minutes – done.

At 2,500 ppm CO₂ (half the MAK value according to TRGS 900), a clear piezo tone sounds and a red LED flashes gently: time to ventilate! Precise infrared sensor, 230 V continuous operation, no battery required. Ideal for classrooms, open-plan offices, waiting rooms, medical practices, and workshops – everywhere many people spend extended time together. The GX-D2 is the smart, flexible reminder for fresh air and a clear mind.

The GX-D2 technology is clever and flexible: an external NDIR infrared sensor with cable allows measurement exactly where the air stagnates or people are breathing. The alarm tone is distinct, the red LED flashes gently, and it is perfectly suited for sensitive areas such as waiting rooms and clinics.

After ventilation, it silences automatically. Outlet operation means it is always ready for use, and the sensor position can be adjusted – near the floor for faster response or higher up for larger rooms.

The GX-D2 is more than a device – it’s the invisible air saver with perfect placement. Whether 30 students in a classroom, 25 colleagues in an open office, or patients in a waiting room: around 1,400 ppm the air becomes “very bad,” but the GX-D2 warns much earlier and exactly where it matters.

Teachers open windows, managers start ventilation, and patients stay relaxed. Parents, employers, and doctors love the instant installation and targeted measurement. No drilling required – just optimal placement of the sensor. The robust design and German quality make it a long-lasting performer. It’s the difference between being “tired after 90 minutes” and “energized until the end.”

The GX-D2 at a glance:

• External NDIR sensor: Flexible placement – near the floor or higher, depending on room layout.
• Alarm at 2,500 ppm: Half the MAK value – early alert before fatigue begins.
• Discreet alarm: Clear tone + softly flashing LED – ideal for waiting rooms.
• Plug & Play: 230 V socket – installation takes only seconds.
• Precise infrared sensor: Durable, maintenance-free, and accurate.
• Ready in 3 minutes: Short warm-up time – instant protection.
• No battery: Continuous operation – always ready for use.
• Made in Germany: Highest quality and reliability from Schabus.

Applications: Where the GX-D2 ensures fresh air precisely

The GX-D2 is the perfect ventilation reminder for all busy areas with high occupancy:

• Classrooms & schools: Sensor at breathing height – students stay focused.
• Open-plan offices: Optimally placed sensor – productivity stays high.
• Waiting rooms & medical practices: Discreet alarm – keeps patients calm.
• Conference & meeting rooms: Clear thinking during long meetings.
• Workshops & production areas: Flexible sensor positioning – workers breathe freely.
• Daycare centers & seminar rooms: Beneficial for both children and adults.
• Co-working spaces: Many people, one sensor – everyone stays alert.

With the GX-D2, fresh air begins exactly where it’s needed – and fatigue disappears. It is the flexible, precise solution for anyone wanting healthier indoor environments.

Scope of delivery

• GX-D2 gas alarm device with external sensor
• User manual

Safety instructions

• Before installing or operating the device, carefully read the user manual.
• Packaging material is not a toy. Keep it away from children.
• Do not open the device; it contains no user-serviceable parts.
• CO₂ from exhaled air disperses well throughout the room; the ideal sensor position is at average nose height of people in the room.

Intended use

• The GAS ALARM GX-D2 with external sensor is a gas detector for carbon dioxide from exhaled air, reminding users to ventilate long before reaching a dangerous level.
• This monitoring system is therefore tuned to a high sensitivity suitable for its intended use.
• The device is suitable for normal household use and must not be used in explosive or industrial environments.
• The GX-D2 primarily serves as a reminder to ventilate.
• Any use other than those described above is not permitted.
• The device does not replace proper installation, use, or maintenance of systems using CO₂ cylinders, including corresponding ventilation and exhaust systems.
