NOTE: UL only evaluated this product to the stated operational voltage range. It was
not evaluated to 80% to 110%. of the voltage range.
The visual strobe models have an on-axis visual strength rating of 200 candela. For
the light dispersion pattern, refer to Tables 3 and 4 on the following pages.
The units can be mounted on a wall or ceiling and have no mounting orientation
restriction. For specific installation and wiring requirements,refer to local codes

Cable Entry Devices
(cable glands, stopping plugs, etc.)
Cable entry devices shall be equipment
certified as flameproof. To maintain the ingress
protection of the flameproof beacon enclosure,
we recommend the cable entry device be IP66
certified.
For the flameproof beacon enclosure, cable
entry devices shall be equipment certified
as flameproof. To maintain the ingress
protection of the flameproof beacon enclosure
we recommend the cable entry device be
IP66 certified. For the increased safety
terminal enclosures (terminal boxes), cable
entry devices shall be equipment certified
as increased safety and shall maintain an
IP rating of IP54.
Cable entry devices for the Beacon and
terminal enclosures shall be equipment
certified as dust protected. To maintain the
ingress protection of the beacon and terminal
enclosures the cable entry devices shall be
IP6X certified.
