PRISM® COMPACT THERMAL SUPPRESSION
OVERVIEW
The Prism® Compact indirect low
pressure thermal suppression system
uses an extinguishing agent commonly
known as Novec 1230. It is a colorless
low odor fluid, low in toxicity, electrically
non-conductive, leaves no residue, and
is an extremely effective fire
suppression agent.
The unit utilizes a UL recognized
component (per UL standard 521), a
Linear Heat Detector known as Firetrace
Automatic Fire Detection Tubing, which
when pressurized with Dry Nitrogen, will
allow the fire suppression valve to
remain in the closed position. This
tubing acts as a continuous linear
thermal detector that ruptures upon
direct flame impingement or at
temperatures above 212°F when
pressurized to 195 psi. Once the
detection tubing is ruptured, the valve
automatically opens, allowing the Novec
1230 agent to flow through the
discharge piping, distributing the extin-
guishing agent through the nozzles into
the protected volume.
When the system’s smoke detector is
activated or the detection tubing is
ruptured, the integrated controls quickly
shut down the fan and close the two
dampers to create a protected volume.
A LED strobe light provides visual
notification of any system discharge.
The stack light also gives visual
feedback on any system malfunction as
detailed in the Operations and
Diagnostics section.
The thermal suppression system
components are identified on page C-2.
