Even to the trained eye, it can be difficult to immediately pinpoint the exact cause of a false fire alarm and know the cure to fixing it. Although every situation is different, we can typically narrow down the common causes to a few scenarios that often reoccur. In the video below, Fire Protection Expert Lee Kaiser explains a some of the most common causes of false fire alarms, as well as the top five causes of unscheduled emergency service calls for ORR technicians.
Recently, ORR Protection Systems has fielded an increased number of questions regarding Video Smoke Detection and Video Flame Detection through our "Ask an Expert" portal. Since the interest seems to be increasing we thought it would be helpful to post the most frequently asked questions about this type of detection.
Corrosion exists in almost every fire sprinkler system installed. Some systems are always filled with water – wet pipe systems. Some systems have air in the pipes until the system is called to fill with water – dry pipe and pre-action systems. Both wet and dry systems have corrosion issues, but they are dramatically worse in dry systems.
Traditional smoke detecting technology, such as beam detection or spot smoke detectors, has a history of being problematic in large open areas. These massive spaces have issues such as smoke stratification caused by high ceilings and/or dilution of the smoke due to high airflow making it difficult for conventional detection devices to operate. Not to mention the significant effort that is necessary just to test and inspect these devices per code requirements.
