The RFII-MRI Sprinkler is intended for
use inside of a magnetic resonance
imaging (MRI) environment, that is, in
an MR system room and close to the
scanner unit. However, this sprinkler is
not intended for use directly inside of
the MR system, such as within the bore
of the scanner unit. During the intended
use, the RFII-MRI Sprinkler must be
mounted at the ceiling to the fixed fire
protection piping system of the MR
system room. Under these conditions,
per non-clinical testing to ASTM F2052-
15, the RFII-MRI Sprinkler was found
to be acceptable for use under a static
magnetic field of 7-Tesla or less. Stan-
dard MRI apparatus are typically in the
3 Tesla range.
Each sprinkler is comprised of the fol-
lowing separately ordered components:
• Cover plate/retainer assembly
• Sprinkler/support cup assembly
The separable, two-piece assembly
design provides the following benefits:
• Allows installation of the sprinklers
and pressure testing of the fire pro-
tection system prior to installation of
a suspended ceiling or application of
the finish coating to a fixed ceiling.
• Permits the removal of suspended
ceiling panels for access to building
service equipment without having
to first shut down the fire protection
system and remove sprinklers.
• Provides for 1/2 in. (12,7 mm) of ver-
tical adjustment to allow a measure
of flexibility in determining the length
of fixed piping to cut for the sprinkler
drops.
The RFII-MRI Sprinklers are shipped
with a disposable protective cap. The
protective cap is temporarily removed
during installation and replaced to help
protect the sprinkler during ceiling
installation or finish. The tip of the pro-
tective cap can be used to mark the
center of the ceiling hole into plaster
board or ceiling tiles by gently pushing
the ceiling product against the pro-
tective cap. When ceiling installa-
tion is complete, the protective cap is
removed and the cover plate/retainer
assembly is installed.

As an option, the RFII-MRI Standard
Response (5 mm bulb) Sprinkler can
be fitted with a silicone air and dust
seal as shown in Figure 5. The air and
dust seal is intended for sensitive areas
where it is desirable to prevent air and
dust from the area above the ceiling to
pass through the cover plate.
