Cirque du Soleil Wireless Fire Alarm Installation – Day 3
This is the 3rd and final part of our video blog, showing our wireless fire alarm installation for the world famous circus the Cirque du Soleil in Munich Germany.
Following on from our last video, we installed two wireless Expanders in the big top tent and a translator outside the security cabin. The wireless detectors, sounders and manual call points were logged on to the closest Expander. Today will be about installing the control equipment and testing the system to the German fire authorities. The fire alarm panel for this Hyfire wireless system is the Kentec Syncro addressable with Argus protocol. Furthermore, this system is to be interfaced with a scope pager system. The two panels were installed adjacent each other in the security cabin.
How is the system designed to operate?
The way the Fire Authorities wanted the system to work, was as follows: in the event of a fire alarm activation, no sounders were to operate, only the pages would activate and vibrate only. The pagers would be with the fire wardens and security personnel. The fire wardens would then investigate to establish whether it is a genuine fire or a false alarm. If a real fire were discovered, the warden would make a decision to evacuate the stadium, by giving instructions over the radio to sound the fire alarm.
The commissioning Parameters for the wireless fire alarm devices
Once the two panels were installed, the commissioning engineer wired the external Translator outside the cabin into the Kentec control panel. Now the system was complete. The engineer had to configure and inspect the radio signal strength of the wireless fire alarm devices and ensure all the signals received at the fire alarm control panel was within the acceptable limits stated by the manufacturer. The signal strength is on a scale of 1 to 5, with 5 being the best signal. The acceptable signal strength is 3 and above. The laptop is now connected to the translator outside the cabin. Reviewing the display, it enables the commissioning engineer to know the radio signal strength of each device. If any device were to be under the level of 3, he would investigate and either try to relocate the device or if this was not possible, an additional expander may be required. However, as you can see from our readings, our design was in good shape.
Testing of the fire alarm by the German fire Authorities.
The moment of truth had now arrived. The German fire authorities were in attendance to inspect the site and the fire alarm. As the system was now programmed for manual activation only, the fire alarm was activated by passing the evacuation button on the front of the control panel. The German fire authorities began testing the system and were duly satisfied with the performance of the fire alarm.
I believe this is the first wireless fire alarm system of this type in Germany. I am not aware of any German wireless fire alarm manufacturer with a product that can achieve the results as seen here.
How much work would be involved, if you had to wire the system?
Can you imagine having to wire the complete site, if opting to carry out the installation using a wired fire alarm system? For venues incorporating a large open space, the best system to use is wireless.
The wireless system can be decommissioned and used over.
This installation in effect took two days to install. On completion of the Circus show, the owners are now in a position to decommissioning the system in accordance with the manufacturer’s guidelines and use it again. I believe the next show is in Holland. Therefore, all that has to be done, is to install the equipment as per the original design and it will work repeatedly.
