The model 490S
The model 490S-1280T and 490S-120T
strobe lights are UL listed for use in Class I & II, Division 2 hazardous
locations. Division 2 locations are defined by the NFPA as shown below. These
units have a Lexan® lens and base and are suitable for use in NEMA 4X outdoor
locations. They may be operated in any position and feature a 1/2” pipe mount
hub. This model is an economical strobe for the listed hazardous locations. The
flash intensity of this model is suited to indoor applications, or where the
strobe flash would have limited competition for visibility from bright ambient
light or light outdoors (e.g. direct or indirect sun light). Compare Joule flash
energy and or candela effective (ECP) rating when comparing different models for
your application.

NFPA Definitions:
Class I, Division 2. A location (1)
in which volatile flammable liquids or flammable gases are handled, processed
or used, but in which the liquids, vapors or gases will normally be confined
within closed containers or closed systems from which they can escape only in
case of accidental rupture or breakdown of such containers or systems, or in
case of abnormal operation of equipment; or (2) in which ignitable
concentrations of gases or vapors are normally prevented by positive
mechanical ventilation, and which might become hazardous through failure or
abnormal operation of the ventilating equipment; or (3) that is adjacent to a
Class I Division 1 location, and to which ignitable concentrations of gases or
vapors might occasionally be communicated unless such communication is
prevented by adequate positive–pressure ventilation from a source of clean air
and effective safeguards against ventilation failure are provided. [See
Section 500–4(b) of NFPA 70, National Electrical Code.] Class II, Division 2.
A location in which (1) combustible dust will not normally be in suspension in
the air in quantities sufficient to produce explosive or ignitable mixtures
and dust accumulations are normally insufficient to interfere with the normal
operation of electrical equipment or other apparatus; or (2) dust may be in
suspension in the air as a result of infrequent malfunctioning of handling or
processing equipment and dust accumulations resulting therefrom may be
ignitable by abnormal operation or failure of electrical equipment or other
apparatus. [See Section 500–5 (b) of NFPA 70, National Electrical Code.]
Architect and Engineer Specifications:
Hazardous Location visual signaling
beacon shall be Tomar model number series 490S-1280T, 490S-120T or approved
equal. The beacon shall be UL Listed Class I, Division II, Groups A,B,C, and
