Definitions

  • Various embodiments of the present technology generally relate to fire suppression systems.

  • Mechanical fire suppression systems are pervasive in restaurants and have been used to protect kitchen and cooking appliances from the threat of a fire.
  • these mechanical fire suppression systems work on a simple principle: a tensioned cable and a group of mechanical fuses or links are installed in the hood above the cooking surfaces and are connected to a trigger mechanism outside the hood area. Examples of fusible and mechanical links are shown in U.S. Patent Application Publication No. 2007/0246234 and U.S. Patent Nos. 3,448,808 and 3,772,499 .
  • the mechanical fuses are unaffected by normal operating temperatures or low heat levels. However, when enough heat is generated by a fire, any fuse exposed to the excessive heat breaks and releases tension on the cable thereby activating the trigger mechanism.
  • the activation of the trigger mechanism causes a cascading series of events, including the activation of a pressurized cartridge, the dispersion of a chemical suppression agent on the cooking surfaces, shutdown of the gas or electricity powering the cooking appliances, changes in air handling equipment, and potentially the activation of visual and audible alarms.

  • An example of one such sequence is the detection line tension is released, followed by a metal-to-metal vibration impact and a broader-range, extended vibration signature due to the discharge of gas.
  • This signature is highly correlated to a discharge of gas. As such, when the system detects this signature indicative of a discharge of gas, the system will not know if this is a real fire, a test or human error without additional sensor data.
  • the acoustic signature will change in both amplitude and frequency content (gas by itself has a different signature than gas and liquid combined).
  • Low- and high-pass filtering techniques along with Fast Fourier Transforms, can be used to ID the event and determine if it was a full discharge or blowdown. The ability to identify this automatically allows the system to earmark the event as a test rather than an alarm (or vice versa).

  • the provisions can be made at the remote monitoring platform to define the discharge event as Real, Test or False Discharge (with additional details) after an inspection is performed. This allows the end user to begin recording a history, which also affords parent companies, insurance providers, and equipment manufacturers an opportunity to assess the probability and types of discharge events that are happening.
  • Owners and system service providers can be notified within seconds of the discharge event.
  • User profiles enable the end user to define his or her type or types of notification and when they occur ⁇ any time versus specific times). Accordingly, the notification capabilities are not solely limited to alarm or discharge notifications.
