Fire protection systems and methods of fire protection systems for protection of a stored commodity. The systems and methods included a plurality of fluid distribution devices disposed above the stored commodity and configured for selective identification and controlled actuation in response to a fire. The systems have a hydraulic demand defined by at least one of: i) a hydraulic design area having a minimum operational area of less than 768 square feet; or ii) less than twelve hydraulic design devices.

Wet fire protection systems and methods for storage

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.

A sensor guard and method of using the sensor guard to protect a sensor element of a fire sensor. The sensor guard includes one or more legs that extend in a direction that is oblique to a central axis of the fire sensor. The fire sensor includes a housing and the sensor element, extending from the housing, for detecting an indication of fire. The sensor guard is mounted on the housing for protecting the sensor element.

Fire sensor having a sensor guard for heat and smoke detection applications

A smoke detector system that includes an airflow barrier installed between a detector base unit and a mounting surface to ensure there is separation between the detector base unit and the mounting surface. The barrier isolates and seals the smoke detector to prevent the formation of condensation in or around the smoke detector. The barrier further includes a cavity that can collect condensation if condensation does occur. The condensation is then directed to a channel that extends around the periphery of the airflow barrier. Additionally, the channel includes weep holes so that condensation has a means to exit the detector.

Smoke detector with airflow barrier

A device and method for facilitating convenient measurement of airflow in a duct detector. The device may include a detector assembly and an airflow sensor mounted within the detector assembly. The airflow sensor may be coupled to a remote control device, such as via control circuitry. A method for testing airflow in the duct detector may be performed by measuring airflow in the detector assembly, generating a signal that corresponds to the measured airflow in the detector assembly, and determining whether the generated signal exceeds a predetermined threshold signal level. If the generated signal does not exceed the threshold signal level, alarms may be activated and/or blowers in a ventilation system may be deactivated.

Duct detector with remote airflow test capability

A device and method for facilitating convenient functional testing of a duct detector is provided. The device includes a duct detector having a remote-controlled test light mounted in a housing thereof, and a detector chamber defined by a filter screen and a plurality of labyrinth members that allow light emitted by the test light to enter the detector chamber. A functional test of the duct detector can be conducted by activating the test light. If the detector is functioning properly, an amount of light emitted by the test light will be detected by the light detector, thereby simulating the presence of an excessive amount of particulate within the detector chamber. The light detector will then generate an output signal that will cause the actuation of alarms and/or the deactivation of a blower system, thereby indicating functionality of the duct detector.
