U
nprecedented engineer and end user response to EST’s Genesis™ line of strobes
made this product one of the most widely talked about new products in the life
safety industry. Its sleek low profile design coupled with outstanding strobe technology has secured Genesis a significant foothold in a market that is traditionally slow to
embrace change. Winning first prize at the ISC product achievement awards in New
York just four weeks after its release in 2000 is clear indication that Genesis has taken
the industry by storm.
As we pause to catch our breath, we find ourselves in the midst of regulatory
changes that have a bearing on all fire alarm strobes. This document is intended to headoff some of the questions you may have concerning new UL 1971 requirements. It is also
an opportunity for us to provide you with new and expanded information on our new
Genesis products and their impact on Integrity – our older line of horns and strobes.
How has UL 1971 changed?
Effective November 1, 2000, two revisions to UL 1971 changed the standards of
measurement applied to new strobes submitted by manufacturers for testing. The
first change affects light dispersion properties, the other affects flash synchronization characteristics.
One of the two changes involved an adjustment to the test that measures
the light dispersion. Under the new procedures strobes are no longer tested strictly
across their horizontal and vertical planes. Instead, vertical testing also includes
compound angles 45 degrees down and to the left, and down and to the right of the
device.
The reason for this change lies with the fact that, traditionally, strobe devices did not disperse light in a smooth arc. Instead, light dispersion from early
strobes employing specular reflectors is characterized by spikes and valleys that
trace a jagged path. This results in uneven light distribution that may deliver inadequate illumination to areas that do not lie directly in the path of either the horizontal
or vertical planes.

Keeping up with
standards is like hitting
a moving target. The
good news is that
Genesis and Integrity
strobes comply right
down the line.
Application Bulletin
How do I make sure my signals meet the compound angle
specification?
If you use EST strobes, this change has no effect on your installations. If you don’t
use EST strobes, the revised UL 1971 standard could provide ample reason for
making the switch.
Thanks to FullLight™ strobe technology, the new compound angle requirement is not an issue for Genesis strobes. FullLight strobe technology provides
exceptionally even light distribution throughout the protected area of all Genesis
strobes. With Genesis, the compound
FullLight Strobe
Technology
angles exceed the new UL 1971 re-
Specular reflector
quirement. And don’t worry about
existing Integrity installations: Integrity strobes have always exceeded this new light measurement
standard, and continue to do so.
Unlike specular reflectors (above right),
Genesis FullLight strobe technology (above left)
bathes the protected area in light. This exceeds
stricter UL light measurement standards that
now include compound angles.
In what way did UL change its synchronization standards?
New synchronization requirements only affect strobes that are to be placed in a
shared field of view. It has been known for some time that individuals susceptible
to photosensitive epilepsy may suffer convulsions in the presence of two or more
strobes that don’t flash in synchronization. As of November 1, 2000, signals that
meet UL 1971 synchronization specifications are required to flash in unison within
10 milliseconds of each other over a two-hour period. We refer to this as enhanced
synchronization.

Edwards Systems Technology
Do all strobes have to meet UL 1971 synchronization
requirements?
No. Both Integrity and Genesis devices self-synchronize to pre-November 2000
standards without any external control modules. Devices installed before that date
do not have to be brought in line with the new requirements unless your Authority
Having Jurisdiction (AHJ) specifically requests this level of compliance. If such
a request is made, or if new strobes are installed, first determine which, if any,
strobes require enhanced synchronization.
How do I determine where UL 1971 synchronization is
required?
According to NFPA 72, synchronized strobes are only required wherever two or
more strobes share the same field of view. While the current Americans with Disabilities Act (ADA) does not explicitly address synchronization, proposed changes
to the law will bring its requirements in line with NFPA 72 on this matter. As a rule
of thumb, if you can see more than one strobe from any point in a protected area,
then synchronization is required.
Do EST strobes meet the new synchronization standard?
Both Genesis and Enhanced Integrity products have already been tested and
have passed the new synchronization requirements with flying colors. Enhanced
Integrity strobes are the product of recent design improvements that have resulted
in internal circuitry that is virtually identical to that found in Genesis strobes and
horn-strobes. The new Enhanced Integrity products deliver improved performance,
more versatile applications and universal compatibility with the Genesis product line.
Enhanced Integrity begins shipping August 13, 2001.

line.
Application Bulletin
Are the Integrity strobes I’ve installed since November 2000
UL approved?
Yes. All EST strobes manufactured and installed before Enhanced Integrity was
available retain their UL listing intact. Older product installed in areas requiring
synchronized strobes (i.e.: strobes that share the same field of view) after the release of Enhanced Integrity will retain their UL 1971 listing, but not as synchronized
products.
Here’s how it works: when a UL standard changes, it is customary for UL
to give manufacturers reasonable time to comply with new standards by allowing
them to deplete existing inventory of finished goods and components or ‘works-inprogress.’ This ‘grandfathers’ the product for a short period to reduce the financial
impact the new standard might have on the manufacturer – and the effect that could
have on the cost of the product to customers. It is also common practice for municipalities to provide grandfather clauses when enacting new codes and standards.
Now that EST has submitted Enhanced Integrity strobes to UL and received their certification to the latest UL 1971 standard, the agency has required
EST to stop manufacturing strobes that claim to be synchronized but do not meet
current UL synchronization requirements – unless we place a caution statement to
that fact inside each carton with the product. All older (non-Enhanced) Integrity
cartons now contain that cautionary note regarding synchronization compliance.
Remember: Enhanced Integrity products meet the new UL synchronization requirements and do not require the cautionary note.
How do I order Enhanced Integrity products?
After August 13, 2001, all Integrity orders will be processed as Enhanced Integrity
orders. Model numbers and ordering procedures will not change. In other words,
once Enhanced Integrity products begin shipping, your orders will automatically be
upgraded to Enhanced products: you don’t need to do anything different.

What if I need non-enhanced Integrity products for service and
maintenance purposes?
After August 13, 2001, when non-enhanced product is desirable, they will remain
available from the Replacement Parts list until stock is depleted. To order older
product, add the “RI” prefix to the model number when ordering. For example,
RI 757-7A-T will get you a non-enhanced red 15/75 cd temporal horn strobe.
How do I distinguish Enhanced Integrity from earlier versions?
While for convenience, the model numbers remain the same, there are several means
of distinguishing Enhanced Integrity products from Integrity products...
• The cd marker on the underside of the strobe lens is red, not black
• The word “Synchronized” appears on the product label
• The date code is “01331” ([year][year][week][week][day]) or more recent
• The carton label reads “Meets UL 1971 synchronization requirements,” and
also bears the text “Enhanced Integrity.”
• The installation sheet identifies the device as synchronized per UL 1971.

Which Integrity products will continue to be available?
Genesis strobes will eventually replace most of the Integrity line. This shouldn’t come as
a surprise. With its advanced features and good looks, Genesis is the superior product.
And considering that it costs you less than its predecessor, the transition is already
proving to be a welcome one. Despite this, Enhanced Integrity products will continue to
fill certain niches, particularly for industrial, outdoor, and harsh applications.
The following is a summary of the impact Genesis has had, or will have, on
the Integrity product line:
Integrity products obsoleted by Genesis:*
• 682 horns – all models
• 202 strobes – 15, 30, 60 cd models only
• 692 horn/strobes – all models
• 757 PowerSaver strobes and horn-strobes – all models
• 757 temporal horn-strobes – 15 and 30 cd models only
Integrity products remaining available:
• 757 temporal horns – all models
• Enhanced 757 temporal horn-strobes – 15/75 and 110 cd models only
• Enhanced 405 strobes – all models
• Enhanced 202 strobes – 15/75, 110 cd models only
• Enhanced 965 speakers and speaker-strobes – all models
• Enhanced 964 speakers and speaker-strobes – all models
* Obsolete product will continue to be available until stock is depleted. Check with Customer Service before ordering.
How can I enable UL 1971 compliant synchronization among
Genesis and Enhanced Integrity strobes?
Thanks to the Genesis Signal Master accessory, downstream Genesis and Enhanced Integrity strobes sharing a common circuit will synchronize to within 10
milliseconds, not just for the two hours now required by UL – but indefinitely!
The Signal Master not only provides UL 1971 compliant synchronization, it
also accomplishes independent horn control over two wires for all downstream Genesis horn-strobes (as always, Integrity horn-strobes require four wires for indepen-

dent horn control, and this is the case for Enhanced Integrity products as well). The
Signal Master even synchronizes temporal horn output among downstream Genesis
and all Integrity devices.
Two Signal Masters are now available: the original Genesis “piggyback”
model, and the recently introduced remote mount model. Both perform identically,
only differing in the way they are mounted. The piggyback Signal Master simply
snaps to the back of any Genesis device. No additional enclosure is required. The
remote mount model borrows its size and shape from the familiar one-gang Signature Series modules. It mounts in a North American 2½ inch (64 mm) deep onegang box, or may be mounted to any SIGA-MP mounting plate, or directly to the
rails provided inside BPS Remote Booster Power Supply cabinets.
Case Study
Challenge: New tenants at a small shopping center with an EST2 system have renovated a store and requested Genesis strobes because of
their low profile design. Two strobes are to be replaced. The rest of the
shopping center is served by older Integrity strobes. Because new strobes
are being installed, the AHJ requires that they meet new UL 1971 synchronization requirements. What do you do?
Solution: Install a Genesis Signal Master on the first of the two Genesis
strobes in the store. This will provide enhanced synchronization for the
two new strobes, and will have no effect on the existing Integrity strobes
downstream or upstream of the Signal Master. Because each store on
the NAC is a separate area, it is not necessary to synchronize the Genesis strobes with the Integrity strobes – as long they are not mixed in the
same field of view.
What-if: What if the tenant next door sees the Genesis strobes and
wants them in his store as well? If the second store is closer to the
control panel, move the Signal Master from the strobe in the first store to
the first Genesis strobe in the second store. If the second store is downstream of the first store, just replace all the older Integrity strobes in that
store with Genesis strobes. That’s all there is to it!

Can I mix Genesis and Integrity strobes on the same circuit?
You can mix Genesis and Integrity devices on the same circuit, but only Genesis
strobes and Enhanced Integrity strobes will synchronize to the latest UL requirements. Non-enhanced Integrity products can safely reside on the same circuit as
Enhanced Integrity and Genesis products, but they should not be placed where
enhanced synchronization is required. The Signal Master has no effect on nonenhanced Integrity products.

Can I synchronize multiple NACs with a single Signal Master?
If survivability is a top priority for your system, then it is recommended that each
NAC be controlled by its own dedicated Signal Master. This kind of built-in redundancy will ensure that any problems with a single Signal Master will be limited to the
NAC it controls. Having said that, it is possible to use the Sense 1 input on the BPS
Booster Power Supply to provide enhanced synchronization to all its on-board NACs.
With this technique, all the devices that reside on all the BPS NACs will be synchronized to UL 1971 standards.
By daisy-chaining two or more Booster Power Supplies together via their
Sense 1 inputs/outputs it is even possible to extend enhanced synchronization across
multiple Booster Power Supplies. The diagram below illustrates how this is achieved.

Is the Signal Master always the best way to achieve precision
synchronization?
While the Genesis Signal Master provides an excellent synchronization solution for
conventional and analog control panels alike, there is an even better solution for
EST3 and QuickStart Signature Series NACs. That solution is the new Signature
Series CC1S Synchronization Control Module.
When used in place of the already-familiar CC1 control module, the CC1S
provides enhanced synchronization for all strobes on its Notification Appliance Circuit (NAC). And what’s more, it even synchronizes strobe flashes among other
CC1S modules on the same Signature data loop This means that all strobes – Genesis or Enhanced Integrity – connected to CC1S modules on the same Signature
data loop flash in precise synchronization within the new UL tolerances. Large
areas, such as “big box” stores, where more than one NAC serves a single protected area will certainly benefit from this innovation.
Remember: Use only Genesis and Enhanced Integrity strobes on
the same circuit. Even under the control of the CC1S, Genesis and
non-Enhanced Integrity strobes should not be mixed within the same
field of view.
The CC1S is supported by QuickStart Signature Series NACs and Signature Series NACs running under EST3 Version 2.0 or higher. Like the Signal Master, the CC1S also synchronizes temporal horn output among all devices under its
control.

Which method of synchronization should I use?
The method of synchronization best for your application depends largely on the
notification appliance circuit. If it is Signature Series controlled and running under
QuickStart or EST3, then the CC1S is likely your best choice. In this case, achieving
enhanced synchronization is simply a matter of using the CC1S in place of the CC1
control module that hosts the NAC wiring on which compatible strobes are to be
synchronized. Multiple CC1S modules on the same Signature data loop will
synchronize all compatible devices on NACs controlled by those CC1S modules.
To synchronize devices on conventional NACs, such as those provided by
EST1 and LSS4 control panels, use the Genesis Signal Master. Installing a Signal
Master on the device closest to the control panel or into a BPS Booster Power
Supply will provide enhanced synchronization for all downstream Genesis and Enhanced Integrity devices. Do not, however, mix Genesis and non-Enhanced Integrity strobes in the same field of view, as they will not synchronize with each other.

Can I still use the Genesis Signal Master for horn control on
circuits synchronized by the CC1S?
Absolutely. Synchronization provided by the CC1S takes precedence, leaving the
Signal Master only providing two-wire horn control for its downstream Genesis
devices. This does not affect the operation of the CC1S.

This wiring configuration uses the SIGA-CC1S to provide enhanced synchronization to
NACs on a Booster Power Supply. It will synchronize either Genesis or Enhanced
Integrity strobes while providing independent horn control for resident Genesis devices.

Will the CC1S work with IRC-3 and EST2 Signature Panels?
The CC1S is compatible only with EST3 and QuickStart Signature Series NACs. Only
the Signal Master will provide precision synchronization for IRC-3 and EST2 applications, as well as for conventional panels such as EST1, LSS4, and QuickStart QSC.
Case Study
Challenge: You are installing strobes in a parking garage. The control
panel is an EST2. Enhanced Integrity strobes are the best choice because they are rated for outdoors and harsh environments. You need
precision synchronization, but you can’t use the CC1S because it’s not
supported by EST2. What do you do?
Solution 1: Install a remote mount Signal Master in a one-gang box or
BPS Booster Power Supply. Run the wiring from this device out to the
Integrity devices in the parking garage. The Signal Master will synchronize all the connected Enhanced Integrity strobes to UL 1971 synchronization standards.
Do I need these external modules to have UL 1971 listed
signals?
No. Keep in mind that even without the Signal Master or the CC1S providing precision synchronization, all EST strobes meet UL 1971 listing requirements. This
has always been the case, and remains so. Separate components are only necessary where two or more strobes share the same field of view and when your AHJ
requires the project to be brought up to the latest code (NFPA 1999).

Why does the listing label on the back of Genesis and Integrity
devices seem self-contradictory?
Looking at the label as a whole, it is contradictory. On one line it says “Not to be
used as a visual public mode alarm notification appliance.” Below that it says “Signaling appliance for the hearing impaired.” Which is it?
The answer is both. UL 1638 is the standard that governs private mode and
outdoor visual signaling, but it does not cover signaling devices for use in the public
mode or for the hearing impaired. UL

ments cannot be deviated from under
any circumstances – even if the label is
unclear as a result. To meet a wider
range of applications, Integrity and Genesis strobes are listed to both UL
1971 and UL 1638 and the labels must bear the required text for each of the two
standards. Despite what the label says, both Integrity and Genesis strobes are listed
for signaling in the private mode and in the public mode for the hearing
impaired. In fact, this is nothing new for EST. A similar label has appeared on
Integrity products for years.
Here’s a rule of thumb to follow when looking at one of these confusing
labels: put your thumb over the part of the label that doesn’t apply to your application. Then look again.

What is the temporal strobe output feature available with
Genesis strobes, and how can I use it?
Snipping the circuit board configures the device to flash in time with the temporal
horn output, (i.e.: flash, flash, flash, pause). This method is currently approved for
private mode applications only. That’s why
Genesis strobes are listed to both UL 1638

steady to temporal

to edge of circuit board

cut from circle J1
to edge of circuit board
(private mode) and UL 1971 (public mode).

Coordinating both the audible and
visual output of the device provides a more
ordered and less distracting signal. Because
one in four flashes is skipped in the temporal mode, there is also a 25 per cent reduction in operating power. While this will have

no bearing on current draw calculations, it will cut battery requirements.
For example, if 3 amps worth of continuously-flashing (i.e.: non-temporal)
strobes were operating for 30 minutes, then 1.5 ampere hours would be required (3
x ½ hours). If those same strobes were set to follow a temporal pattern that produces only 75 per cent of the output over the same period of time, then only 1.125
ampere hours would be required (1.5 ampere hours x 75 per cent). This reduction
can cut costs and save installation time by reducing the backup battery requirements
across the system.
Is the temporal strobe output synchronized?
UL 1638, the standard governing private mode signaling, does not require enhanced
synchronization at this time. Nonetheless, all Genesis devices are self-synchronized
without the need for external modules. If, however, UL 1971 level enhanced synchronization for temporal strobe output is desired, this too can be achieved with the
Signal Master or CC1S as described above.
