What is Smoke Control Systems Testing?

A smoke control system consists of mechanical and electrical components which manage the movement of smoke within a building during a fire event. These systems are designed to keep smoke out of certain areas of the building to protect occupants and first responders when evacuating.

Smoke control systems vary from building to building depending on their age and construction, but are usually comprised of pressurization fans and a series of ancillary devices like automatic door openers or a relay to disable the make-up air units. These devices are all connected to the fire panel and operate automatically when the system is in an alarm state.

This startup wants to build VR headsets with 'human eye-resolution'

Originally from techcrunch.com

Earlier this month, Google virtual reality head Clay Bavor discussed the company’s efforts on a mind-boggling 20 megapixel screen that was currently under development. The screens would be a staggering 17x resolution improvement on displays in current generation VR systems like the Rift and Vive. They would also be totally unusable, because at the frame rates needed for VR, such displays would burn through 50-100 GBs of data per second.The key for working this out would be utilizing a technology called foveated rendering to track where a user’s eyes are looking and ensure that only the area at the center of their vision is being rendered at full resolution.While this will undoubtedly be a technology that enables the future of high-end VR, it’s still one that relies on expensive displays that aren’t even widely available yet.

A Finnish startup is positing that they’ve come up with a way to bring human-eye level resolution to VR headsets through a technique that will direct a pair of insanely high-resolution displays to the center of your vision. With current technology, the company claims this will enable perceived resolutions north of 70 megapixels.Varjo, which means “shadow” in Finnish, is looking to bring this technology to higher-end business customers by next year at a price of “less than $10,000” according to the company.

Why show off this tech now? Largely because the company is currently raising cash stateside and was just awarded a few patents related to these technologies last week.I had the chance to demo a prototype of the company’s technology last week using a modified Oculus Rift headset with Varjo’s display systems embedded.I suppose the best testament to the company’s technology was that I spent most of the demo questioning whether my eye sight had actually been improved. After being dropped into an apartment scene, I was almost disturbed by my ability to read the spines of books on bookshelves several feet away.

Frequently asked
questions

Find out more about how we can help make your existing buildings safer with our engineering, testing, and verification services. If you have any questions or require additional information, we're here to assist you in making the right choice for your safety and engineering needs.

WHY DO YOU NEED TESTING PROCEDURES?

The Ontario and National Fire Codes require regular testing of the smoke control systems in a building in order to ensure that they are operating properly in accordance with operation and test procedures designed by a Professional Engineer or Architect. Buildings are required to maintain records of these tests to prove compliance.

Recent high profile high-rise building fires have increased public interest in fire safety. Fire departments have increased their scrutiny of smoke control systems and are visiting buildings around the GTA to check procedures and records. If documentation does not meet the Code requirements, buildings are served with an Inspection Order with a very tight timeline to resolve the outstanding issues.

In addition to regulatory compliance, formal specifications for testing and maintenance procedures can also be used by property managers when tendering fire alarm and HVAC service contracts to ensure the contractors are submitting competitive prices on an established scope of work.

DOES ONTARIO FIRE CODE SECTION 7.3 APPLY TO MY BUILDING?

The requirements of this section apply to all residential high-rise buildings over 18m (approximately 6 stories) in height, as well as certain commercial buildings (depending on their occupant load). This section of the OFC (Ontario Fire Code) requires smoke control equipment to be maintained to ensure that it is fully operational and tested in accordance with procedures designed by a Professional Engineer (P.Eng.) or Architect.

It is a common misconception that once an engineered procedure has been obtained, it is sufficient to complete the annual fire alarm tests as usual. In fact, the OFC requires that the inspections and tests established in the procedures be implemented. Engineered procedures require testing at prescribed intervals, usually quarterly.

HOW CAN TFG HELP?

Having all the required trades on-site at the same time is expensive, difficult to coordinate, and ultimately unnecessary. Furthermore, service personnel, while qualified to operate the equipment, may not understand how the smoke control system is intended to operate. Most of the testing procedures are best and most efficiently completed by a single qualified person. Trace Fire Group (TFG) personnel are selected and trained to provide industry-leading expertise in the testing of smoke control systems. A single member of our staff can replace two or more service contractors. By retaining TFG to complete the periodic smoke control testing, corporations can expect considerable annual savings over the cost of completing testing with service contractors.
