Non-Magnetic Concealed Pendent Sprinkler from Johnson Controls for MRI Rooms

Listings and Innovations

Hospital MRI rooms pose specific challenges to fire sprinkler systems. Because of the need to protect sensitive MRI equipment from electrical and magnetic interference, non-ferrous materials must be used to protect this valuable life-saving equipment.

Johnson Controls has just launched the Tyco®  RFII-MRI 5.6 Flat-Plate Concealed Pendent Sprinkler. Used with BlazeMaster® CPVC pipe and fittings, the new sprinkler offers designers and hospital building managers an affordable non-magnetic solution.


Extended Coverage Option Allows for Fewer Sprinklers

The new non-ferrous sprinklers provide quick response in the event of a fire, and are available in standard and extended coverage models. The extended coverage option requires fewer sprinklers and less pipe, further reducing the potential for sprinkler system interference with MRI equipment.  

The sprinklers are both UL and cUL listed and are tested up to 7 Tesla (the measurement of magnetic field strength). This rating allows the sprinklers to withstand more than twice the magnetic strength of standard MRI equipment (typically 3 Tesla).

Two temperature options provide flexibility when mounting sprinklers near potential heat sources. The new sprinkler is available at 155°F (68°C) sprinkler and 139°F (59°C) cover plate as well as at 200°F (93°C) sprinkler and 165°F (74°C).

BlazeMaster CPVC Is A Reliable, Cost-Effective Non-Ferrous Choice, Too

Paired in a design with BlazeMaster CPVC pipe and fittings, the new sprinkler heads offer a reliable fire protection solution at an affordable price for MRI rooms classified as a light hazard occupancies.

Steel piping is, of course, not an option in a health facility’s MRI room. Non-ferrous metal choices included copper, brass or stainless steel, but all of these add significant expense.

BlazeMaster CPVC piping is a more cost-effective choice than virtually any metal piping. This lightweight thermoplastic is capable of withstanding prolonged exposure to high heat and elevated pressure. It does not melt or drip in a fire, nor does it allow a fire to spread. 

Installation costs and time are reduced using CPVC. Its light weight allows for easy fabrication and flexibility. Reduced maintenance is also a factor to consider; unlike metal piping, CPVC resists corrosion and scale.

Simply put, the combination of the new Tyco® RFII-MRI 5.6 Flat-Plate Concealed Pendent Sprinkler and BlazeMaster CPVC is the perfect solution for MRI room fire protection needs.
