VFR-400 • 5403548 • REV D • 10/07
Design Guidelines
People trained in the design of special hazard systems shall determine the selection and placement of the initiating devices and
notifi cation appliances connected to the VFR-400. This responsible party shall also be familiar with the premises being protected.
The equipment shall be installed in accordance with the manufacturers instructions, the applicable version of NFPA 72 and all
local codes and ordinances. For systems employing cross zoning of smoke detectors for the activation of the release circuit, this
can include but is not limited to the installation of photoelectric and ionization types of detectors on separate zones. One of each
type of detector on separate zones shall be installed in the coverage area selected for a single detector. The detectors would be
installed in close proximity to each other.
The responsible party shall also determine the theory of operation regarding the programming sequence.
General Description
The model VFR-400 is a listed and approved, microprocessor based fi re control/releasing panel. It is primarily designed for use
as a releasing panel for pre-action, Surefi re
®
, Firecycle
®
III, and deluge, water based extinguishing systems. They may also be
used as stand alone fi re control panels. These units comply with NFPA-13, NFPA-15,NFPA-72, and NFPA-750.
The VFR-400 complies with UL Standard 864, ULC S527-77, Canadian Electrical Code Part 1 C22.1, ULC S524, FM, CSFM
and NYMEA.
