INSTALLATION INSTRUCTIONS SL SERIES CEILING MOUNT HORN HORN STROBES AND CLEAR AND AMBER LENS this product according to this instruction manual Please keep this instruction manual for future reference Siemens LED based SL Series LED3 SLHC horn SLSC strobe and SLHSC horn strobe appliances are designed for easy instal All models are for 24V operation The SLHC horn is also for 12V operation SLSC and SLHSC are designed for ceiling mounting SLHC may be mounted on the wall or ceiling Please read these instructions carefully before using this product Failure to comply with any of the following in cautions and warnings could result in improper application candela setting installation and or operation of these in an emergency situation which could result in property DSCage and serious injury or death to you and or others Siemens LED based SL Series meets NFPA 2016 20 millisecond light pulse duration code requirements In addition the Siemens based SL Series product line has been UL ULC listed as compatible with all Fire Alarm Control Panels FACP and acces that have been determined to be compatible with Siemens model ST Strobe based products including the ST CH SE SEF SA STH ZR and ZH Series The maximum number of SL Series devices per NAC is determined by divid maximum current rating of the FACP NAC divided by the total appropriate current rating for the selected candela output of the SL devices with a maximum of 105 SL Series devices per NAC Refer to FACP installation instructions for more detail The Siemens based SL Series strobes may be installed in the same notification zone and field of view with any ST Strobe based product Characteristics Patterns Sound Output Power 1 Specifications SLHSC UL 1971 ULC S526 16 SLSC A UL1638 ULC S526 16 SLHC UL 464 ULC S525 16 Use

Listed as They are intended to be used with Fire Alarm Control Panels FACPs notification circuits are UL Listed as Refer to the FACP instructions or the Siemens Strobe Compatibility Data Sheet PN for special application and strobe synchronization compatibility These appliances were tested to the regulated voltage limits of 16.0 33.0 Volts for 24 volt models and 8.0 17.5 Volts for 12 volt models filtered dc for the 12 volt range and either filtered dc or unfiltered dc for the 24 volt range voltage Do not apply voltage outside of this Check the minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the circuit resistance to determine the applied voltage to the strobes The maximum wire impedance between strobes shall not exceed 35 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 Circuit NAC DSC sync module or Siemens power supplies does not exceed the power sources rated or the current ratings of any fuses 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 could result in property damage and injury or death to you and or others AND MOUNTING BASE All strobe appliances have in out wiring terminals that accept two 12 to 18 American Wire Gauge AWG wires at each screw termi Strip leads 3 8 inches and 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 wiring diagrams is for the operation of the appliances The polarity is reversed by the FACP during supervision 2 Wire Connection Figure 1 LED Horn strobe Wiring Wiring method shall be in accordance with CSA C22.1 Canadian Electrical Code Part 1 Safety Standard for Electrical Section 32 Do not fully back out terminal screws AND MOUNTING SETTINGS The SLHSC and SLHC are factory set for the most common application of High dB and Code 3 The SLHSC and SLSC are factory to 15 candela Candela factory settings are shown in Figure 4 Output Horizontal and Vertical Values 3 SLHSC SLSC SLSC A Expected Light Output Figure 4 Horn Strobe Candela Selector Check that the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit espe if sheathed multiconductor cable or 3 4 inch conduit fittings are used the limits shown for the mounting option comply with the National Electrical Code NEC Siemens recommends use of the larg backbox option available and the use of approved stranded field wires whenever possible to provide additional wiring room for easy 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
