The long standing problem with our fire alarm and sprinkler system appears to have been resolved. Despite several previous attempts, the root cause of the problem was not revealed until a fourth floor resident noticed a wet spot developing on the ceiling. Sentry Management called on a service company to investigate the source in the attic space. Two pin hole leaks were discovered and were spraying water.
The pipelines above the fourth fourth are, by design, dry and pressured with air. The only time that the system is charged with water is during testing or in conjunction with a fire alarm. After testing the pipelines are drained. It was discovered that the pipe was not completely drained and contained several gallons of water, probably due to improper slope. Corrosion compounded by the air pressure created the spray.
Upon further inspection, another pin hole was discovered in another location. A more detailed inspection is warranted. Fortunately, these leaks were very low by volume.
The faulty sections of pipe have been replaced. The fire alarm low pressure alarm also has stopped.
Please note that during this period, the building was fully protected. In the event of a fire the alarm and sprinkler systems would have done their job.
