Fire protection systems and methods for ceiling-only high-piled storage protection. The systems and methods include a fluid distribution, detection and control sub-systems to identify one or more fluid distribution devices for controlled operation to address a fire.

Controlled system and methods for storage fire protection

Fire protection systems and methods for ceiling-only high-piled storage protection. The systems include a plurality of fluid distribution devices disposed beneath a ceiling and above a high-piled storage commodity having a nominal storage height ranging from a nominal 20 ft. to a maximum nominal storage height of 55 ft. and means for quenching a fire in the storage commodity. The stored commodity to be protected may include exposed expanded plastics. The fluid distribution devices include a frame body having an inlet, an outlet, a sealing assembly, and an electronically operated releasing mechanism supporting the sealing assembly in the outlet.

Mis-wired addressable loops are determined by enabling all loops and identifying all devices communicating on all loops. A list of all identified devices is recorded. One at a time, each loop is disconnected, a list of devices that are disabled is determined and recorded for the disconnected loop, and the loop is reconnected. When all of the loops have been processed, the lists of disabled devices are compared and those devices that are wired improperly are determined.

Method and apparatus for determining mis-wired addressable loops

Jumper and ground faults are detected within an alarm system. Jumper detection applies to devices having two or more functions (e.g., audible horn and visual strobe). When operated with a single circuit, jumpers typically remain installed in such devices to provide power to all functions. However, if the devices are installed in alarm systems equipped with multiple functions, the jumpers should be removed to allow functions to operate independently and correctly. To detect unremoved jumpers, all loops to separate functions except one are isolated. After isolation, a predetermined signal is presented to the non-isolated loop and current is compared to a reference value. If jumpers exist between this non-isolated loop and another supposedly isolated loop, the additional parallel resistance produces an abnormal signal. To perform ground fault detection, lines of devices may be sequentially isolated (i.e., disconnected) at the control panel via software control until a previously detected ground fault disappears. The line that is isolated and which causes the fault to disappear is the line containing the fault.
