Genesis EG4 Series

Overview

The Genesis line of life safety signals are the smallest, most
compact audible-visible emergency signaling devices in the world.
Protruding no more than one inch from the wall, Genesis speakers
and speaker-strobes blend with any decor.

Life safety appliances feature textured housings in architecturally
neutral white or traditional life safety red.

Thanks to patented breakthrough technology, Genesis strobes do
not require bulky specular reflectors. Instead, an exclusive design
channels and conditions light to produce a highly controllable
distribution pattern.

Speaker-strobes feature selectable candela output with a conven­iently-located switch on the bottom of the device. The candela
setting remains clearly visible even after final installation.

All Genesis speakers include a DC blocking capacitor to allow
electrical supervision of the audio distribution circuit. The speaker
with its sealed back construction provides extra durability and
improved audibility.

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-mounted public-mode notification appliances for the hearing
impaired. 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.

All Genesis strobes meet UL synchronization requirements (within
10 milliseconds over a two-hour period) when used with a syn­chronization source. Synchronization is important in order to avoid
epileptic sensitivity.

Field Configuration

Genesis speakers may be set for ¼, ½, 1, or 2 watt operation. The
wattage setting is visible through a small window on the bottom
of the device and is changed by simply sliding the switch until the
desired setting appears in the window. The speaker does not have
to be removed to change the wattage.

Genesis speaker-strobes feature selectable candela output. The
output setting is visible through a small window on the bottom of
the device and is changed by simply sliding the switch until the
desired setting appears in the window. The speaker-strobe does
not have to be removed to change the output.

Installation and Mounting

All models are intended for indoor wall mounted applications only.
Speakers and speaker-strobes are flush mounted to a North­American 4” square electrical box, 21/8” (54 mm) deep or a Euro­pean 100 mm square box. Signals may be surface mounted to a
Genesis surface-mount box (see ordering information for details).

Two tabs at the top of the signal unlock the cover to facilitate
mounting. The shallow depth of Genesis devices leaves room
behind the signal for extra wiring. Once installed with the cover in
place, no mounting screws are visible.

Edwards recommends that these speaker-strobes always be in­stalled in accordance with the latest recognized edition of national
and local codes. Refer to installation sheet for mounting height
information.

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.

Genesis speaker-strobes may also be configured for temporal
flash. This battery-saving feature is intended for private mode
signaling only. To set the device for temporal flash, snip the circuit
board as shown in the Jumper Locations diagram above.
