Exceder LED3 series LFHNK3 Sounder and LFHSK3 Sounder Strobe appliances are designed for easy installation All are for 24V operation The LFHNK3 Sounder and LFHSK3 Sounder Strobe are rated as low frequency devices per UL 464 suitable sleeping areas per NFPA 72 The LFHNK3 sounder may be wall or ceiling mounted Please read these instructions carefully before using this product Failure to comply with any of the following instruc cautions and warnings could result in improper application candela setting installation and or operation of these products an emergency situation which could result in property damage and serious injury or death to you and or others Wheelock Exceder LED3 Series meets NFPA 2016 20 millisecond light pulse duration code requirements In addition the Wheelock Exceder LED3 product line has UL ULC listed as compatible with all Fire Alarm Control Panels FACP and accessories that have been determined to be compatible with Wheelock model RSS based products including the RSS CH E EH ET ST HS MT S8 SA STH and Z Series The maximum number of LED3 devices per NAC is determined by divid the maximum current rating of the FACP NAC divided by the total appropriate current rating for the selected candela output of the LED3 devices with a maximum of LED3 devices per NAC Refer to FACP installation instructions for more detail The Wheelock Exceder LED3 Series strobes may be installed in the same notifica zone and field of view with any RSS Strobe based product 1 Specifications UL 1971 CAN ULC S526 16 UL 464 CAN ULC S525 16 Use Only 0 C 49 C 32 F 120 F 93 R H line

appliances were tested to the regulated voltage limits of 16.0 33.0 Volts for 24 volt models using filtered DC or unfiltered DC Do apply voltage outside of this range Check the minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the circuit wir resistance to determine the applied voltage to the strobes The maximum wire impedance between strobes shall not exceed 35 ohms Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off Make sure that the total RMS current required by all appliances that are connected to the system primary and secondary power notification appliance circuits DSM sync modules or Wheelock power supplies does not exceed the power sources rated capacity the current ratings of any fuses on the circuits to which these appliances are wired Overloading power sources or exceeding fuse ratings could result in loss of power and failure to alert occupants dur an emergency which

connect to screw terminals Break all in out wire runs on supervised circuits to ensure integrity of circuit supervision as shown in Figure 2 The polarity shown in 3 the wiring diagram is for the operation of the appliances The polarity is reversed by the FACP during supervision Figure 2 Wire Connection Figure 3 LED Strobe Wiring Wiring method shall be in accordance with CSA C22.1 Canadian Electrical Code Part 1 Safety Standard for Electrical Installations 32 Do not fully back out terminal screws The LFHSK3 and LFHNK3 are factory set for the most common application of Code 3 Sounder

and with sheathed multiconductor cable or 3 4 inch conduit fit are used the limits shown for the mounting option comply with the National Electrical Code NEC Cooper Wheelock recommends use of a square backbox and the use of approved stranded field wires whenever possible to provide additional wiring room for easy installa and minimum stress on the product from wiring Do not over tighten mounting screws Excessive torque can distort the base and may affect operation When using power tools to screw down the mounting plate to the electrical backbox ensure the torque is set to the lowest available OPTIONS Remove the lens protector tape and the speaker protector before replacing the appliance cover grille Connect field wiring to contacts on back of device Dress wires back into backbox Install device as shown in Figure 6 to a 4 inch square backbox Figure 7 to a surface mount backbox or Figure 8 to a single gang with the provided pan head screws Snap beauty cover over device backbox must be recessed or flush with the wall surface Device only has one mounting orientation LED light element should be pointed towards ground To remove the appliance insert a small flat bladed screwdriver into
