- Contact us to find out more
- Carefully read the following instructions prior to installation of this device
- Always keep this pamphlet for future reference
- Ensure that the gas detection system is wired correctly and is only used for the purpose for which it is intended
- Operation When the HCF100 senses the presence of freon gas it sends a 4 - 20mA signal to the detector proportional to the level of gas
- The detector then operates a pre-alarm relay used for remote sirens or visual indicators if the level of gas continues to rise
- The main alarm relay is activated to break the electrical supply to a safety shut off valve, and is fixed at 300ppm of freon R134a
