Is it possible (maybe someone has encountered this already) to trigger a false alarm on a VESDA system or photoelectric smoke detector from refrigerant discharge mixture that contains both refrigerant and oil?
I'm concerned about the combination possibly affecting the fire alarm system. Sent in anonymously for discussion. Click Title to View | Submit Your Question | Subscribe

It is possible for a refrigerant leak to cause a false alarm. I doubt oil will cause a false alarm being heavier than air.

To second Mike, I don't believe oil would set off any false alarms. 1/4/2022 09:53:16 am
In our experience we have seen accidental refrigerant leaks during recharges causing false alarms with both VESDA detectors and photoelectric spot smoke detectors. It is fairly common in data centers where there are recharges of refrigerant circuits in CRAC units from time to time. 3/16/2022 06:03:04 am
We have the same situation. Thank you for the answers! 4/14/2022 03:58:13 am
One of the most common signs of a refrigerant leak will be noticeable near the vents. If you feel weak or warm air moving through the vents while running the air conditioning, you may have leaking refrigerant. The leak may be preventing the system from producing cool air. Leave a Reply. |
