Branchport Avenue Branch N J 07740 631 2148 Thank you for using our products INSTRUCTIONS ET SPEAKERS AND STROBE SPEAKERS this product according to this instruction manual Please keep this instruction manual for future reference Series ET Speakers and Strobe Speakers are UL Listed under Standard 1971 for Signaling Devices for the Hearing Impaired UL Standard 1480 for Speaker Appliances The LSM strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela on axis with low current draw The Series ET is designed for multiple power requirements with high dBA output at each power All ET models offer a choice of field selectable taps 1 8 to 8 Watts for either 25.0VRMS or 70.0VRMS audio systems The Series design incorporates a high efficiency speaker for maximum output at minimum power across a frequency range of 400 to 4000Hz and a sealed back construction for extra protection and improved audibility All inputs are compatible with standard reverse supervision of circuit wiring by a Fire Alarm Control Panel FACP Series ET Strobe Speakers incorporate a Xenon flashtube solid state circuitry enclosed in a rugged Lexan cid 210 lens to provide maximum reliability for effective visible signaling The Strobe are available with a choice of four UL Listed strobe options Series LS LSM MS and IS All models are Listed for indoor use models are Listed for ceiling or wall mount and LSM models are Listed for wall mount only with the backboxes specified in instructions see Mounting Options All CAUTIONS and WARNINGS are identified by the symbol All warnings are printed in bold capital letters READ THESE INSTRUCTIONS CAREFULLY FAILURE TO COMPLY WITH ANY OF THE FOLLOWING CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION INSTALLATION AND OR OF THESE PRODUCTS IN AN EMERGENCY SITUATION WHICH COULD RESULT IN PROPERTY DAMAGE AND INJURY OR DEATH TO YOU AND OR OTHERS 1 UL Listed Models and Ratings dBA at 10 Feet Strobe Voltage Watts models are UL Listed at 15cd and meet 75cd on axis Min Nom 15 15 1 dBA is rated per UL Standard 1480 for Speaker Appliances 2 Four 4 watt rating is only available with 70.0VRMS input 1993 1997 Wheelock Inc All rights reserved E 1 of 7 WHEELOCK STRONGLY RECOMMENDS THAT THE VOLTAGE APPLIED TO THESE PRODUCTS BE WITHIN RATED INPUT VOLTAGE RANGE THE APPLICATION OF IMPROPER VOLTAGE MAY RESULT IN DEGRADED OR DAMAGE TO THESE PRODUCTS WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY DEATH TO YOU AND OR OTHERS UL Listed Rated Input Voltage is 20.0 31.0VDC using either filtered DC or unfiltered full wave rectified FWR voltage Check minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the circuit wiring to determine the applied voltage to the strobes All VFWR voltages are measured with DC volt meter Multiply VFWR by 1.11 to convert to VRMS 2 Strobe Current Requirement AMPS Average Current Peak Current Inrush Current MAKE SURE THAT THE TOTAL AVERAGE CURRENT TOTAL PEAK CURRENT AND TOTAL INRUSH REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM PRIMARY AND SECONDARY SOURCES AND SIGNALING CIRCUITS DO NOT EXCEED THE POWER SOURCES RATED CAPACITY OR THE RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED OVERLOADING SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT DURING AN EMERGENCY WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR TO YOU AND OR OTHERS calculating the total average peak or inrush currents Use Table 2 to determine the highest value of Average Current an individual strobe across the expected operating voltage range of the strobe or the highest value of Inrush Current or Peak Current whichever is higher of an individual strobe across the expected voltage range of the strobe then multiply the by the total number of strobes be sure to add the currents for any other appliances including audible signaling appliances by the same source and include any required safety factors the inrush current or peak current exceeds the power supplies inrush capacity the output voltage provided by the power supplies drop below the listed voltage range of the appliances connected to the supply and the voltage may not recover in some types of supplies For example an auxiliary power supply that lacks filtering at its output stage either via lack of capacitance and or lack battery backup across the output may exhibit this characteristic Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off In addition to the inrush current shown in Table 2 the 75cd strobes also produce a brief inrush current that lasts about 15 with a peak value of 2.0 Amps 2.8 Amps for FWR input E 2 of 7 DISTRIBUTION in
