Overview
Genesis WG4 Series speakers and speaker-strobe appliances
are among the most versatile emergency appliances of their kind.
Rated for indoor or outdoor use, they are suitable for a wide range
of wet and harsh environments with a listed operating temperature
range of as low as -31°F to as high as 151°F (-35°C to 66°C).
Field-configurable light and sound output settings add to their onsite flexibility, while optional FIRE markings make them ideal for fire
alarm applications.
These appliances are suitable for indoor and outdoor applications,
and are ideal for challenging conditions such as parking garages
and process areas. They are listed for mounting on the ceiling or
the wall, and thanks to an ingenious full backplane sealing gasket,
can be installed to recessed (in-the-pour/block) electrical boxes.
WG4 signals also mount to suitable surface boxes served by raceways. Optional color-matched trim skirts provide a clean, finished
appearance. All appliance wiring is accomplished room-side for
easy installation.
WG4 Series appliances feature highly intelligible and efficient mylar-cone loudspeakers. These are dual-voltage (25.2V or 70.7V),
and have field-selectable output taps ranging from 80.8 dBA to
90.0 dBA. The multi-candela strobes are available with clear lenses and in two output categories – standard and high-output. They
are precision-timed to meet UL 1971 synchronization standards,
and field-configurable for one of four candela intensities. Wattage
and candela settings are viewable even after installation through
an innovative sealed viewport display.

Speaker Application
The suggested sound pressure level for each signaling zone used
with alert or alarm signals is a minimum of 15 dB above the average ambient sound level or 5 dB above the maximum sound level
having a duration of at least
60 seconds, whichever is
greater. This is measured 5
feet (1.5 m) above the floor.
Doubling the distance from
the signal to the ear will
theoretically cause a 6dB
reduction in the received
sound pressure level. The
actual effect depends on
the acoustic properties of
materials in the space. Doubling the power output of a
device (e.g.: a speaker from
1W to 2W) will increase the
sound pressure level by
3dBA.

Strobe Application
Genesis clear-lensed strobes are UL 1971-listed for use indoors
as wall- or ceiling-mounted public-mode notification appliances for
the hearing impaired, and UL 1638-listed for outdoor applications.
Prevailing codes require strobes to be used where ambient noise
conditions exceed specified levels, where occupants use hearing
protection, and in areas of public accommodation.
Visible appliance synchronization is required to avoid causing
issues with people who have Photosensitive Epilepsy (PSE). Notification appliance synchronization is also generally required when
more than one strobe appliance are in the same field of view from
any one location. All Genesis strobes meet UL synchronization
requirements (within 10 milliseconds over a two-hour period) when
used with a synchronization source.
WARNING: These devices will not operate without electrical power.
As fires frequently cause power interruptions, we suggest you discuss
further safeguards with your local fire protection specialist.
Edwards recommends that these devices always be installed in
accordance with the latest recognized edition of national and local
codes. Refer to the appropriate codes and standards for mounting
height information.
Field Configuration
Genesis WG4 speakers may be set to 70- or 25-Volt operation,
and for ¼, ½, 1, or 2 watt operation. The wattage setting (represented by the letters Z,Y, X, and T) is changed by removing the
cover and simply sliding the S1 switch until the desired setting appears. The setting remains visible through a small window on the
front of the device after the cover is installed. The voltage setting
(70V or 25V) is toggled at S3. This setting is not visible after the
cover is replaced.
Genesis WG4 speaker-strobes also feature selectable candela
output. The actual light output for a given selection depends on
whether it is a high output model or a standard output model. Refer to the specification tables for corresponding settings. The candela setting (represented by the letters D, C, B, and A) is changed
by removing the cover and simply sliding the S2 switch until the
desired setting appears. The setting remains visible through a
small window on the front of the device after the cover is installed.
