INSTALLATION INSTRUCTIONSSL2 LOW FREQUENCY SOUNDER STROBES AND SOUNDERSWITH PRE-WIRE/PRE-TEST (WALL MOUNT)Siemens Industry, Inc.Building Technologies Division2 Gatehall DriveParsippany, NJ 07054PN P85753-001ASiemens Canada LimitedBuilding Technologies Division1577 North Service Road EastOakville, Ontario, L6H 0H6CanadaPN P85753-001A Page 1IMPORTANT: All audible and visual signaling appliances must be installed in accordance with all applicable national and local fire alarmcodes and any other required regulatory agencies.The Siemens SL2FS Sounder (520Hz) and SL2FSS Sounder Strobe (110/177cd) appliances are designed for easy installation with a pre-wire capable mounting plate. All models are for 24V operation. The SL2FS Sounder and SL2FSS Sounder Strobe are rated as lowfrequency devices per UL 464, suitable for sleeping areas per NFPA 72. The SL2FS sounder may be wall or ceiling mounted.The Siemens SL2 strobe meets NFPA 2016 20 millisecond light pulse duration code requirements. In addition, the Siemens SL2 productline has been UL/ULC listed as compatible with all Fire Alarm Control Panels (FACP) and accessories that have been determined to becompatible with Siemens ST Strobe based products including the SL, ST, SE, SEH, SET, S-HQ, STH, AS, CH, HS, MTH and Z series. Themaximum number of SL2 devices per NAC is determined by dividing the maximum current rating of the FACP NAC by the total currentrating of one SL2 device, with a maximum of 105 SL2 devices per NAC. Refer to FACP installation instructions and relevant compatibilityguides for more detail. The Siemens SL2 Series may be installed in the same notification zone and field of view with any Siemens ST, SL,and Z series Strobe based product.Siemens Low Frequency Sounder Strobe can provide a synchronized strobe appliance when used in conjunction with an FACP thatincorporates the Siemens Sync Protocol, a DSC Sync Module or a Siemens Power Supply. When set to the T3/4 setting, a DSC SyncModule can toggle the Low Frequency Sounder between Code 3 (T3) for fire/emergency evacuation and Code 4 (T4) for carbon monoxide(CO).CAUTION: Do not change factory applied finishes. “DO NOT PAINT”.ATTENTION: Ne pas modifiez les finitions appliquées en usine. “NE PAS PEINTURER”IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. FAILURE TO COMPLY WITH ANY OF THE FOLLOWINGINSTRUCTIONS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION AND/OR OPERATION OF THESE PRODUCTS INAN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOUAND/OR OTHERS.SPECIFICATIONS:Table 1: SpecificationsModels SL2FSS (Sounder Strobe), SL2FS (Sounder)Agency Strobe: UL1638, UL1971,CAN/ULC-S526-16Sounder: UL464, CAN/ULC-S525-16Input Voltage DC or FWR, 24V Regulated, 16 to 33V (All models)Sounder Patterns Non-Sync: Continuous, Code 3 (field selectable)Siemens Sync Protocol: Code 3 Sync, T3/T4 Sync Selectable (with DSC)Coded Operation: Use Continuous Setting on SL2FS Sounder Only ModelStrobe Light Output 110cd or 177cd (field selectable)NAC Characteristics Max. line resistance: 35ΩEnvironmental Indoor Use Only. 0° C - 50° C (32° F - 122° F) 93% R.H.* Code 3/Code 4 (T3/T4) operation requires the use of the Siemens Sync Protocol or DSC module.Table 2: Current Ratings (AMPS) **Sound Setting Regulated 24DC (16-33VDC) Regulated 24FWR (16-33VRMS)SL2FSS110cdSL2FSS177cdSL2FS SL2FSS110cdSL2FSS177cdrSL2FSContinuous (CONT) 0.164 0.256 0.098 0.235 0.348 0.138Code 3 (T3) 0.164 0.256 0.098 0.235 0.348 0.138Code 3/Code 4 (T3/4) 0.164 0.256 0.098 0.235 0.348 0.138** Setting will determine the current draw of the product.When calculating the total currents use Table 2 to determine the highest value of RMS current for an individual appliance, then multiplythese values by the total number of appliances. Be sure to add the currents for any other appliances, including audible signalingappliances powered by the same source, and to include any required safety factors.Important: When installing strobes in an open office or other areas containing partitions or other viewing obstructions, special attentionshould be given to the location of the strobes so that the operating effect can be seen by all intended viewers. Furthermore, the intensity,number, and type of strobes shall be sufficient to alert the intended viewer with proper illumination, regardless of the viewers orientation.A small possibility exists that the use of multiple strobes within a person’s field of view, may induce a photo-sensitive response in personswith epilepsy. Strobe reflections in a glass or mirrored surface might also induce such a response. To minimize this possible hazard,Siemens strongly recommends that the strobes installed should not present a composite flash rate in the field of view which exceeds five(5) Hz at the operating voltage of the strobes. Siemens also strongly recommends that the intensity and composite flash rate of installedstrobes comply with levels established by applicable laws, standards, regulations, codes and guidelines.Table 2A: Sound Output – dBA at 10FtSound Setting Reverberant dBA per UL 464 Anechoic dBA per CAN/ULC-S525-16For Dwelling Use Only16V 24V 33V 16V 24V 33VContinuous 80 80 80 80 80 80Code 3 80 80 80 80 80 80Code 3/Code 4 80 80 80 80 80 80Table 2B: ULC Directional Characteristics-3dB +/- 90 Degrees Horizontal, +/- 89 Degrees Vertical-6dB +/- 90 Degrees Horizontal, +/- 90 Degrees VerticalWIRING DIAGRAMS:Figure 1:FROM PRECEDING APPLIANCEFACP, POWER SUPPLYOR SYNC MODULETO NEXTOR E.O.L.R.APPLIANCE+-+-*Refer to DSC Sync Module instruction sheet or Siemens Power Supplies for additional information.Figure 2:1. This model has in-out wiring terminals that accept two #12 to #18 American Wire Gauge (AWG) wires ateach screw terminal. Strip leads 3/8 inches and connect to screw terminals.2. Break all in-out wire runs on supervised circuits to assure integrity of circuit supervision as shown inFigure 2. The polarity shown in the wiring diagrams is for operation of the appliances. The polarity isreversed by the FACP during supervision.NOTES:1. The strobe will produce 1 flash per second over the "Regulated Voltage" range.2. Strobe are not designed to be used on coded systems in which the applied voltage is cycled on and off.3. The maximum number of SL2 strobes on a single notification appliance circuit shall not exceed 105.4. These appliances are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL Listedas “Regulated.”5. These appliances were tested to the regulated voltage limits of 16.0-33.0 Volts. Do not apply voltage outside of this range. Checkthe minimum and maximum output of the power supply and standby battery and subtract the voltage drop from the circuit wiringresistance to determine the applied voltage to the strobes. The max wire impedance between strobes shall not exceed 35 ohms.6. Make sure that the total RMS current required by all appliances that are connected to the system’s primary and secondary powersources, notification appliance circuits, sync modules, or power supplies does not exceed the power sources rated capacity or thecurrent ratings of any fuses on the circuits to which these appliances are wired.7. The Code 3 temporal pattern (1/2 second on, 1/2 second off, 1/2 second on, 1/2 second off, 1/2 second on, 1-1/2 off and repeat) isspecified by ANSI and NFPA 72 for standard emergency evacuation signaling. Code 3 Horn shall be used only for fire evacuationsignaling and not for any other purpose.8. The Code 4 temporal pattern (100 ms on, followed by 100 ms off, for 4 cycles, followed by 5 seconds of silence and repeat), is specifiedby ANSI and NFPA 720 for carbon monoxide emergency signaling.9. The effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when it is stored in theoriginal cartons and not subjected to misuse or abuse.
