EST EST3 v1 0 Integrity and Genesis Strobe Application Bulletin

EDWARDS SYSTEMS TECHNOLOGY Update and Genesis Strobes Bulletin July 2001 In what way did UL change its synchronization standards Do EST strobes meet the new synchronization standard Are the Integrity strobes I installed since November UL approved How do I order Enhanced Integrity products What if I need non enhanced Integrity products for and maintenance purposes Which Integrity products will remain available How can I enable UL 1971 compliant synchronization Genesis and Enhanced Integrity strobes Can I mix Genesis and Integrity strobes on the same circuit Can I synchronize multiple NACs with a single Signal Master Is the Signal Master always the best way to achieve precision synchronization Can I still use the Genesis Signal Master for horn control on circuits synchronized by the CC1S to these questions and more inside Manuals Online Update and Genesis Strobes Bulletin July 2001 has UL 1971 changed 1 do I make sure my signals meet the compound angle specification 2 what way did UL change its synchronization standards 2 all strobes have to meet UL 1971 synchronization requirements 3 do I determine where UL 1971 synchronization is required 3 EST strobes meet the new synchronization standard 3 the Integrity strobes I installed since November 2000 UL approved 4 do I order Enhanced Integrity products 4 if I need non enhanced Integrity products for service and maintenance purposes 5 do I distinguish Enhanced Integrity from earlier versions 5 Integrity products will continue to be available 6 can I enable UL 1971 synchronization among Genesis and Integrity strobes 6 I mix Genesis and Integrity strobes on the same circuit 8 I synchronize multiple NACs with a single Signal Master 9 the Signal Master be used on Class A wiring 10 the Signal Master always the best way to achieve precision synchronization 11 I use the Signal Master for horn control on circuits synchronized by the CC1S 14 the CC1S work with IRC 3 and EST2 Signature Panels 15 I need these external modules to have UL 1971 listed signals 15 does the label on the back of Genesis and Integrity seem self contradictory 16 is the temporal strobe output feature available with Genesis strobes 17 the temporal strobe output synchronized 17 next 18 else is yesterday 20 Manuals Online and FullLight Technology are of Edwards Technology Inc Systems Technology engineer and end user response to EST Genesis line of strobes this product one of the most widely talked about new products in the life industry Its sleek low profile design coupled with outstanding strobe technol has secured Genesis a significant foothold in a market that is traditionally slow to change Winning first prize at the ISC product achievement awards in New just four weeks after its release in 2000 is clear indication that Genesis has taken industry by storm we pause to catch our breath we find ourselves in the midst of regulatory that have a bearing on all fire alarm strobes This document is intended to head some of the questions you may have concerning new UL 1971 requirements It is also opportunity for us to provide you with new and expanded information on our new products and their impact on Integrity our older line of horns and strobes has UL 1971 changed November 1 2000 two revisions to UL 1971 changed the standards of applied to new strobes submitted by manufacturers for testing The change affects light dispersion properties the other affects flash synchroniza characteristics of the two changes involved an adjustment to the test that measures light dispersion Under the new procedures strobes are no longer tested strictly their horizontal and vertical planes Instead vertical testing also includes angles 45 degrees down and to the left and down and to the right of the reason for this change lies with the fact that traditionally strobe de did not disperse light in a smooth arc Instead light dispersion from early employing specular reflectors is characterized by spikes and valleys that a jagged path This results in uneven light distribution that may deliver inad illumination to areas that do not lie directly in the path of either the horizontal vertical planes Manuals Online up with is like hitting moving target The news is that and Integrity comply right the line Bulletin do I make sure my signals meet the compound angle you use EST strobes this change has no effect on your installations If you don EST strobes the revised UL 1971 standard could provide ample reason for the switch to FullLight strobe technology the new compound angle re is not an issue for Genesis strobes FullLight strobe technology provides even light distribution throughout the protected area of all Genesis With Genesis the compound exceed the new UL 1971 re And don worry about Integrity installations In strobes have always ex this new light measurement and continue to do so specular reflectors above right FullLight strobe technology above left the protected area in light This exceeds UL light measurement standards that include compound angles reflector Strobe what way did UL change its synchronization standards synchronization requirements only affect strobes that are to be placed in a field of view It has been known for some time that individuals susceptible photosensitive epilepsy may suffer convulsions in the presence of two or more that don flash in synchronization As of November 1 2000 signals that UL 1971 synchronization specifications are required to flash in unison within milliseconds of each other over a two hour period We refer to this as enhanced Manuals Online Systems Technology all strobes have to meet UL 1971 synchronization Both Integrity and Genesis devices self synchronize to pre November 2000 without any external control modules Devices installed before that date not have to be brought in line with the new requirements unless your Authority Jurisdiction AHJ specifically requests this level of compliance If such request is made or if new strobes are installed first determine which if any require enhanced synchronization do I determine where UL 1971 synchronization is to NFPA 72 synchronized strobes are only required wherever two or strobes share the same field of view While the current Americans with Dis Act ADA does not explicitly address synchronization proposed changes the law will bring its requirements in line with NFPA 72 on this matter As a rule thumb if you can see more than one strobe from any point in a protected area synchronization is required EST strobes meet the new synchronization standard Genesis and Enhanced Integrity products have already been tested and passed the new synchronization requirements with flying colors Enhanced strobes are the product of recent design improvements that have resulted internal circuitry that is virtually identical to that found in Genesis strobes and The new Enhanced Integrity products deliver improved performance versatile applications and universal compatibility
