Fire Hydrant System/Sprinkler System Fire Fighting Systems Fire Hydrant Syst...RajyogFireServicesPv
Fire Hydrant System,System Information,Operational Information,Fire Alarm System ......
Being one of the oldest but yet the most effective and common fire fighting solution, a well designed and a well laid out Hydrant System forms the backbone of the entire fire fighting system. It comprises of heavy duty above & underground piping with accessories. External and Fire Escape Hydrant valves are provided at every strategic location. A fire hydrant is a pipe that allows water to flow from a water main with the control of a valve in order to put out a fire.
A fire sprinkler system is an active fire protection measure, consisting of a water supply system, providing adequate pressure and flow rate to a water distribution piping system, onto which fire sprinklers are connected
An automatic sprinkler system is intended to detect, control and extinguish a fire, and warn the occupants of occurrence of fire. The installation comprises fire pumps, water storage tanks, control valve sets, sprinkler heads, flow switches, pressure switches, pipe work and valves. The system operates automatically without human intervention.
It has become more apparent over the years how important it is to have adequate fire protection in every building. For most people (Non-technical), what comes to mind when they think of fire protection are Sprinkler system, smoke detectors and fire extinguishers. However, these two elements only cover a small portion of the protection services you should have at all times. There are in fact two types of fire protection: Active Fire Protection (AFP) and Passive Fire Protection (PFP). One type of protection must not be chosen over the other. On the contrary, both AFP and PFP must be used together for full fire protection. It is important to understand the difference between AFP and PFP so that you are confident that your building is protected by both types.

Messaging Brokers are intrinsic part of our infrastructure and our experience with HornetQ has not been really great.
We have experienced issues that forced us to perform restarts multiple times a day and sometimes they weren't sufficient to fix the issue and data cleanup was needed resulting in loss of important messages.
Lack of documentation, lack of proper support and lack of stability of HornetQ broker are some of the reasons for looking into new Messaging Brokers.
During this session I will present the path we have taken to Prioritize Features -> Compare Brokers -> Eliminate -> Benchmark and the findings together with recommendations.
This task resulted in implementation of generic messaging broker benchmarking tool in Java, called Benchmark.io which we are intending to open source.
