Abstract
The virtual accelerator is for detecting an alarm condition within a pressurized gas sprinkler system. It has a pressure monitor for monitoring pressure within the pressurized gas sprinkler system, and generating a pressure signal representative of the pressure thereof; a sampler for sampling the pressure signal at a given frequency during a predetermined period of time, and generating a series of pressure values; and a detector for detecting variations of the pressure values, and generating an alarm signal if the variations are within a predetermined range. A method for detecting an alarm condition within a pressurized gas sprinkler system is also proposed.

A virtual accelerator for detecting an alarm condition within a pressurized gas sprinkler system, comprising:
- a pressure monitoring means for monitoring pressure within the pressurized gas sprinkler system, and generating a pressure signal representative of the pressure thereof;
- sampling means for sampling the pressure signal at a given frequency during a predetermined period of time, and generating a series of pressure values;
- and
- detecting means for detecting variations of the pressure values, and generating an alarm signal if the variations are within a predetermined range, the detecting means further comprising a low pass filter for low pass filtering the variations of the pressure values, and generating a first positive signal if the variations are within a low pass filter range.
A method for detecting an alarm condition within a pressurized gas sprinkler system, comprising the steps of:
- (a) monitoring pressure within the pressurized gas sprinkler system, and generating a pressure signal representative of the pressure thereof;
- (b) sampling the pressure signal at a given frequency during a predetermined period of time, and providing a series of pressure values;
- and
- (c) detecting variations of the pressure values, and generating an alarm signal if the variations are within a predetermined range, the step of detecting variations further comprising the step of (i) low pass filtering the variations of the pressure values, and generating a first positive signal if the variations are within a low pass filter range.
