757 Series
Overview
EST’s Integrity Series life safety and mass notification/emergency
communications (MNEC) re-entrant speakers and speaker-strobes
are high quality appliances for emergency voice communications,
as well as alert and alarm tone signals.
Integrity’s rugged plastic housing is made from durable and fire retardant, high impact plastic with a slightly textured surface. Housings are rated for outdoor use and are available in red or white.
Integrity’s ingenious mounting plate firmly holds the device in place
with a single screw. This ensures quick and attractive installation.
A separate trim plate is not required. Speaker terminals accept up
to #12 AWG (2.5mm²) wire for polarized connections. Strobe connections are made to color-coded wire leads.
Integrity MNEC appliances offer emergency signaling with amber
lenses. They are ideal for applications that require differentiation
between life safety and mass notification alerts.
Life safety strobes are shipped with standard wall mount style FIRE
lens markings. Where ceiling orientation, other languages, or different lens markings are required, Edwards offers optional LKW and
LKC series Lens Marking Kits. These optional lens markings simply
snap on to the strobe. Consult Edwards for availability of special
lens markings.
Integrity strobes are designed for 16 to 33 Vdc operation and
must be connected to signal circuits that output a constant (not
pulsed) voltage. A diode is used to allow full signal circuit supervision.

Standard Features
• UL 1971-listed synchronizing strobe
Integrity strobes synchronize to the latest UL 1971 requirements when used with a synchronization source.
• Genesis-compatible
All Genesis and Integrity strobes on the same circuit meet UL
1971 synchronization requirements when used with an external
control module.
• MNEC models with amber lenses available
• Listed for public and private mode applications
UL 1971-listed as signaling devices for the hearing impaired
and UL 1638-listed as protective visual signaling appliances.
• 98 dBA Output
High efficency driver produces a loud 98 dBA at 15 watts.
• Multiple Output Taps, 25 or 70 Volt Models
Easy to select for 2, 4, 8, and 15 watt operation. Integrity
speakers are supplied with a DC Blocking Capacitor for audio
circuit supervision.
• Outdoor rated
Durable red or white Noryl front plate is ideal for outdoor, industrial or harsh environments.
• Field changeable field markings
Lens language or standard “FIRE” marking is easily changed
with optional LKW (wall orientation) and LKC (ceiling orientation) lens kits.

NOTE: The installation of visible and audible signals are subject to national and local standards, codes, and ordinances.

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 ef-
Typical Sound Output Distribution
dBA measured in anechoic cham-
ber
fect 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.
Strobes
Edwards clear strobes are UL 1971-listed for use indoors as wall- or
ceiling- 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.
Consult with your Authority Having Jurisdiction for details.
As part of the Enhanced Integrity line of products, 757 Series
strobes exceed UL synchronization requirements (within10
milli-seconds over a two-hour period) when used with a
synchronization source. Synchronization is important in order to
avoid epileptic sensitivity.
Integrity strobes are fully compatible with Edwards Genesis signals.
MNEC Applications
Integrity MNEC appliances are available with amber lenses. They
are ideal for applications that require differentiation between life
safety and mass notification alerts.
NOTE: The flash intensity of some visible signals may not be adequate to
alert or waken occupants in the protected area. Research indicates that
the intensity of strobe needed to awaken 90% of sleeping persons is approximately 100 cd. Edwards recommends that wall-mounted appliances
in strobes in sleeping rooms be rated at at least 110 cd.
WARNING: These devices will not operate without electrical power. As
fires frequently cause power interruptions, further safeguards such as
backup power supplies may be required.
Typical Wiring
The strobe must be connected to signal circuits which output a constant (not pulsed) 24 Vdc voltage. Depending on the model, the
speaker must be connected to either 25 or 70 V audio circuits.

Current Draw Notes and Comments
1. Current values are shown in mA.
2. UL Nameplate Rating can vary from Typical Current due to measurement methods and instruments used.
3. Edwards recommends using the Typical Current for system design including
NAC and Power Supply loading.
4. Use the Vdc RMS current ratings for filtered power supply and battery AH calculations. Use the Vfwr RMS current ratings for unfiltered power supply calculations.
5. Fuses, circuit breakers and other overcurrent protection devices are typically
rated for current in RMS values. Most of these devices operate based upon
the heating affect of the current flowing through the device. The RMS current
determines the heating affect and therefore, the trip and hold threshold for those
devices.
Sound level output notes
• All values shown are dBA measured at 10 feet (3.01m).
• UL1480 values measured in reverberation room.
• Average values are measured in anechoic chamber.
