Model WV450XL Series
Failure to follow all safety precautions and instructions may result in
property damage, serious injury, or death.
Overview of Model WV450XL Series
The Federal Signal Model WV450XL Series is ideally suited for
explosive atmospheres and harsh environments. It is designed to serve
the demanding needs of offshore marine and land based industrial
applications. The housing is made of corrosion resistant components,
which dramatically reduces the cost of long-term maintenance.
The WV450XL Series beacons use all of the latest techniques in
non-metallic housing construction. The body of the product is
glass reinforced polyester (GRP) and 316 stainless steel hardware.
The use of GRP in the design improves corrosion resistance and
reduces weight as compared to traditional metal housings. The GRP
construction also saves time and money over the life of the product by
reducing or, in most cases, completely eliminating the need to perform
regular eld inspections of the ame path.
The WV450XL Series comes standard with metric entries, a 316
stainless steel dome guard and an extended life LED emitter.
The ameproof “D” versions come standard with a 316 stainless
steel mounting brackets and two M20 entries for eld cable gland
connections. The increased safety “E” versions have the added feature
of a terminal chamber with three M20 entries. The increased safety
design allows for quick eld termination and pass-through wiring.
There are seven dome colors: amber, blue, clear, green, magenta, red,
and yellow.
Product features:
• 316 stainless steel mounting bracket included
• Available voltages: 24 Vdc and 110-220 Vac
• Eight selectable ash patterns (Table 1 on page 18)
