Gas Alarm GX-D1

GX-D1 CO₂ Alarm: The Subtle Ventilation Reminder for Fresh Air in Schools, Offices & Clinics

When the air gets stuffy, performance drops – and the GX-D1 from Elektrotechnik Schabus GmbH & Co. KG makes that audible before anyone notices it.

Simply plug it into a wall socket (upper outlet = less sensitive, lower outlet = more sensitive), wait 3 minutes, and you’re ready to go.

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!

High-quality NDIR infrared sensor, 230 V continuous operation, no battery, no installation required. Ideal for classrooms, open-plan offices, waiting rooms, medical practices, or workshops – anywhere many people spend time together. The GX-D1 is the simplest and most reliable reminder for better air and clear minds.

The technology behind the GX-D1 is practical and discreet: a precise NDIR sensor continuously measures the air and reacts accurately at 2,500 ppm – early enough to prevent fatigue and lack of concentration, but without constant beeping.

The alarm tone is distinct, and the red LED flashes softly – perfect for waiting rooms and medical practices where bright flashing could cause distraction. After ventilation, it stops automatically.

Powered directly from a plug socket, it’s always ready for use and can be positioned flexibly: higher for larger rooms, lower for faster response.

The GX-D1 is more than a device – it’s the silent air saver. Whether it’s 30 students in a classroom, 20 colleagues in an office, or patients in a waiting room – at around 1,400 ppm the air becomes “very poor”, and the GX-D1 gives an early warning. Teachers open windows, managers start ventilation, and patients remain comfortable.

Parents, employers, and doctors appreciate the instant setup and the clear, simple alert – no complicated operation. Its robust design and German engineering make it a long-lasting device. It’s the difference between being “tired after two hours” and “focused until the end of the day.” With the GX-D1, you’re investing in well-being – and you can feel it immediately.

The GX-D1 at a glance:

• Alarm at 2,500 ppm: Half the MAK value – early warning before fatigue starts.
• Subtle alert: Clear tone + softly flashing red LED – ideal for waiting rooms.
• Plug & Play: 230 V socket – ready in seconds, no installation needed.
• NDIR infrared sensor: Precise, durable, maintenance-free.
• Flexible positioning: Upper socket = less sensitive, lower socket = more sensitive – adapts to the room.
• Ready in 3 minutes: Short warm-up time – immediate protection.
• No battery: Continuous operation – no replacements necessary.
• Made in Germany: Top quality and reliability by Schabus.

Applications: Where the GX-D1 ensures fresh air

The GX-D1 is the ideal ventilation reminder for all busy indoor environments:

• Classrooms & schools: Students stay alert – teachers ventilate in time.
• Large & open-plan offices: Productivity instead of the afternoon slump.
• Waiting rooms & medical practices: Subtle alarm – keeps patients calm.
• Conference & meeting rooms: Clear minds during long sessions.
• Workshops & production areas: Clean air for craftsmen – sustained performance.
• Kindergartens & seminar rooms: Beneficial for both children and adults.
• Co-working spaces: Many people, one GX-D1 – everyone stays fit.

With the GX-D1, fresh air starts at the power socket, and fatigue disappears. It’s the simplest and most cost-effective investment in health and performance.

Scope of delivery

• GX-D1 Gas Alarm Device
• User Manual

Safety instructions

• Before installing or operating the device, read the user manual carefully.
• Packaging material is not a toy. Keep it away from children.
• Do not open the device, it contains no user-serviceable parts.

Intended use

• The GAS ALARM GX-D1 with integrated sensor is a CO₂ detector for carbon dioxide from exhaled air, giving an early reminder to ventilate well before concentrations reach a hazardous level.
• This monitoring system is therefore set to a sensitivity level appropriate for its intended purpose.
• The device is suitable for normal domestic use and must not be used in explosive or industrial environments.
• The GX-D1 is primarily intended as a reminder to ventilate.
• Any use other than that described above is not permitted.
• This device does not replace proper installation, operation, or maintenance of CO₂ systems including associated ventilation and exhaust systems.
