273 Branchport Avenue Branch NJ 07740 631 2148 Thank you for using our products INSTALLATION INSTRUCTIONS SERIES NS MCW TWO WIRE APPLIANCE MOUNT VERSION this product according to this instruction manual Please keep this instruction manual for future reference Series NS MCW Horn Strobe Appliance requires only 2 wires for operation of the horn and strobe appliance The NS provides four selectable candela settings 15 30 75 110 The NS MCW is the ideal choice for applications where the audible feature is required The NS MCW Appliance is UL Listed under Standard 1971 for Signaling Devices for the Hearing Impaired UL Standard 464 for Audible Signal Appliances It is listed for indoor use only and equipped with an NS Mounting Plate NSMP can be mounted to single gang double gang 4 backbox 100mm European backbox or SHBB surface backbox See Mounting This strobe model is Listed for wall mounting only The NS MCW Appliance uses a Xenon flashtube with solid state enclosed in a rugged Lexan cid 210 lens to provide maximum visibility and reliability for effective visible signaling horn portion of the NS MCW Appliance can be field set to provide either Continuous Horn or Code 3 Horn The sound output be field set for High HI or Low LO dBA NS MCW Horn Strobe can also be used with a Sync Module SM Dual Sync Module DSM or Power Booster PS 12 24 8 to synchronized strobe and synchronized Code 3 signal strobe model is designed for use with either filtered DC VDC or unfiltered Full Wave Rectified VRMS input voltage All inputs polarized for compatibility with standard reverse polarity supervision of circuit wiring by a FACP 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 Ratings 2 dBA Sound Output for 24VDC Per UL 464 dBA at 10 Feet Horn 3 Horn The Strobe will produce 1 flash per second over the Regulated Voltage range Anechoic dBA is measured on axis in a non reflective free field test room using fast meter response For peak dBA measured peak meter response add 5dBA to anechoic values as shown in Table 2 Reverberant dBA is a minimum UL rating based on pressure measurements in a reverberant test room This model is UL Listed for indoor use with a temperature range of 32oF to 120oF 0oC to 49oC and maximum humidity of 85 WARNING OPERATING THE NS AUDIBLE APPLIANCES SET ON CODE 3 HORN LOW dBA AT MINIMUM VOLTAGE WILL NOT MEET THE 75dBA MINIMUM UL REVERBERANT SOUND LEVEL REQUIRED FOR PUBLIC MODE FIRE SERVICE NOTED BY IN TABLE 2 THIS SETTING IS ACCEPTABLE ONLY FOR GENERAL SIGNALING NON ALARM USE USE THE HIGH dBA SETTING WITH THIS TONE FOR PUBLIC MODE SERVICE C 1 of 8 2000 Wheelock Inc All rights reserved C 2 of 8 THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS OF 16 33 VOLTS FOR 24V MODELS FILTERED DC OR UNFILTERED FULL WAVE RECTIFIED FWR DO NOT APPLY 80 AND 110 OF THESE VOLTAGE FOR SYSTEM OPERATION CHECK THE MINIMUM AND MAXIMUM OUTPUT OF THE POWER SUPPLY AND STANDBY BATTERY AND THE VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE THE APPPLIED VOLTAGE TO STROBES THE MAXIMUM WIRE IMPEDANCE BETWEEN STROBES SHALL NOT EXCEED 35 OHMS THE MAXIMUM NUMBER STROBES ON A SINGLE NOTIFICATION APPLIANCE CIRCUIT SHALL NOT EXCEED 47 CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT 3 Rated Average Current AMPS with High dBA Setting Peak Current The time duration for the peak current is 1 millisecond In rush current is less than rated peak current 3A Rated Average Current AMPS with Low dBA Setting MAKE SURE THAT THE TOTAL AVERAGE CURRENT AND TOTAL PEAK REQUIRED BY ALL APPLIANCES THAT CONNECTED TO THE SYSTEM PRIMARY AND SECONDARY POWER SOURCES APPLIANCE CIRCUITS SM DSM SYNC AND PS 12 24 8 DO NOT EXCEED THE POWER SOURCES RATED CAPACITY OR THE CURRENT RATINGS OF ANY ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED OVERLOADING POWER SOURCES OR EXCEEDING RATINGS COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY WHICH RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND OR OTHERS calculating the total average or peak currents Use Table 3 and 3A to determine the highest value of Average Current an individual strobe across the expected operating voltage range of the strobe or use Table 3 to determine the highest value of 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 peak current exceeds the power supplies inrush capacity the output voltage provided by the power supplies may drop below the voltage range of the appliances connected to the supply and the voltage may not recover in some types of power supplies For an auxiliary power supply that lacks filtering at its output stage either via lack of capacitance and or lack of battery backup 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 C 3 of 8 DISTRIBUTION PER UL 1971 4 Horizontal Plane in deg Min 15cd UL Min Typ 30cd UL Min Typ 75cd Min 110cd 4A Vertical Plane in deg Min 15cd UL Min
