LEAK DETECTORS
The JCI product range offers Leak detectors ( in order to comply to the EU F-gas Directive ) for the following gases :
• Ammonia ( NH3 )
• Synthetic refrigerants HFC ( R134a , R410a etc ) as shown in this catalogue
• Carbon dioxide ( CO 2
)
• Hydro Carbons ( R290 , R600 )
The MPU multi point units need to be used in combination with the MP series of detectors . The GD / GS series of detectors are standalone detectors and have 3 alarm relays that are factory calibrated depending on the gas type .

The HFC detector alarm levels are set for R134a . But they also indicate for HCFC and CFC although at slightly different levels . Detectors can be adjusted for other gases and customized alarm levels . In this case contact your Johnson Controls representative for information .
NOTE
Sensors are a consumable part . Expected sensor lifetime ≈ 5 years . Sensors can be easily replaced and are available as a spare part . Maintenance : at least once a year ( normal operation / environment ). For details or questions contact your Johnson Controls representative .
