SYSTEMS AND METHODS OF DYNAMIC LOW AIR ALARMS FOR DIFFERENTIAL TYPE FIRE PROTECTION VALVES

An alarm system includes a first pressure sensor, a second pressure sensor, and one or more processors. The first pressure sensor can detect a first pressure of a fluid supply of a dry pipe sprinkler system. The second pressure sensor can detect a second pressure of gas in at least one pipe of the dry pipe sprinkler system. The one or more processors can receive the first pressure from the first pressure sensor and the second pressure from the second pressure sensor, determine a target minimum pressure based on the first pressure, compare the target minimum pressure to the second pressure, and output an indication of an alarm condition based on the comparison.
