Gas detector DD-FR/AP HFC (Refrigerants), 1000/2000/2500ppm R410A, relay output, p-p sensor, 12V power supply (for burglary alarm systems)

Gas detectors for alarm systems – reliable safety

This gas detector is designed for continuous monitoring of refrigerant (Freon) presence in enclosed spaces, integrated with a burglar alarm system. The device cyclically measures the gas concentration in the air, and if defined thresholds are exceeded, it activates an optical and acoustic alarm and transmits information to the alarm control panel via a contact output. This is a key solution to ensure safety in places of potential leakage, such as refrigerant storage facilities, server rooms or air-conditioned rooms.

Wide application and solid construction

The DD-FR/AP detector finds application in many areas where monitoring refrigerant concentration is important:

• Refrigerant storage facilities: monitoring potential leaks and protecting against hazards.
• Rooms with air conditioning and refrigeration units: early detection of failures and minimizing losses.
• Server rooms: protecting sensitive equipment from damage caused by leaking gases.
• Refrigeration industry: process control and ensuring work safety.
• Garages: detecting dangerous gas leaks from vehicles or devices.

The detector's construction has been designed for easy installation and long-term operation. A replaceable sensor module facilitates maintenance and reduces device maintenance costs. The housing made of high-quality ABS plastic ensures durability and resistance to environmental conditions. The possibility of wall or flush-mount installation in a Ø60mm box increases installation flexibility.

Key features and benefits

• High sensitivity: detection of R32 or R410A refrigerants in the range of 1000/2000/2500 ppm.
• Intelligent sensor: ensures measurement stability and long life (estimated at 10 years).
• Built-in microprocessor: guarantees reliable operation, temperature compensation and the ability to read the history of alarm states (available from the manufacturer).
• Three alarm thresholds: standard calibrated thresholds A1, A2 and A3 allow for precise adjustment of the detector's sensitivity to specific needs.
• Contact output: enables integration with a burglar alarm system or other alarm devices.
• Optical and acoustic signaling: informs about exceeding alarm thresholds, ensuring a quick response in case of danger.
• Calibration every 3 years: ensures measurement accuracy and reliable device operation – exceeding the deadline is signaled optically.
• 12V DC power supply: compatible with most alarm systems.

The DD-FR/AP detector is an investment in safety that allows for quick detection of potential hazards related to refrigerant leaks, minimizing the risk of equipment damage and protecting human health. The device is calibrated in its own GAZEX Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which confirms its high quality and measurement accuracy.
