All models are for 24V operation. Series SL2CHC/SL2CHSC Chime is UL Listed for indoor fire protection service under StandardUL464 for Private Mode Audible Signal Appliances as well as ULC-S525-2016 (Audible Signaling Devices for Fire Alarm and SignalingSystems). The SL2 Chime is designed for low current draw and versatile performance. The SL2 Chime offers a choice of 1Hz, 2Hz, coded,or temporal code 3 (T3) operation. It has an adjustable sound level, and operates at a frequency of 890Hz. The Low Profile designincorporates a high efficiency speaker for maximum output at minimum power, and features a sealed back construction for extra protectionand improved audibility. These models are listed for indoor use and ceiling mount with the backboxes specified in these instructions (seemounting options). Model SL2CHC (non-strobe) 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 SL2 Multi-Candela Chime-Strobes can provide a synchronized strobe appliance when used in conjunction with an FACP thatincorporates the Siemens sync protocol, a Sync Module (DSC), or the Siemens Power Supply.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 SL2CHC (Chime), SL2CHSC (Chime-Strobe)Agency Strobe: UL1638, UL1971,CAN/ULC-S526-16Sounder: UL464, CAN/ULC-S525-16Input Voltage DC or FWR, 24V Regulated, 16 to 33V (All models)Chime Patterns 1Hz, 2Hz, Coded, T3 (field selectable, Table 4)Strobe Light Output Strobe: 15, 30, 75, 110, 150, 177cd (field selectable)NAC Characteristics Max. line resistance: 35ΩEnvironmental Indoor Use Only. 0° C - 50° C (32° F - 122° F) 93% R.H.Table 2A: SL2CH Chime – Current and Sound Pressure Level RatingsMaximumRMSCurrentReverberant dBA at 10Ftper UL464for Private ModeAnechoic dBA at 10 Ftper CAN/ULC-S525-16for Dwelling Use OnlyUL/ULC Voltage (Amps) Min Max Min MaxDC 16.0 – 33.0 Vdc 0.022 51 68 61 78FWR 16.0 – 33.0 Vrms 0.022 51 68 61 78Table 2B: Directional Characteristics-3dB +/- 90 Degrees Horizontal, +/- 90 Degrees Vertical (does not reach 3dB)-6dB +/- 90 Degrees Horizontal, +/- 90 Degrees Vertical (does not reach 6dB)Table 3: SL2CHSC Strobe Current Ratings (AMPS) **Regulated 24DC (16-33VDC) Regulated 24FWR (16-33VRMS)Candela Setting 15cd 30cd 75cd 110cd 150cd 177cdDC 0.022 0.030 0.060 0.086 0.125 0.185FWR 0.036 0.050 0.092 0.142 0.196 0.274** Setting will determine the current draw of the product.When calculating the total currents: Use Table 2A and Table 3 to determine the highest value of “RMS Current” for an individual appliance,then multiply these values by the total number of appliances; be sure to add the currents for any other appliances powered by the samesource and include any required safety factors.Make sure that the total RMS current required required by all appliances that are connected to the system’s PRIMARY and SECONDARYpower sources, NAC circuits, DSC Sync Modules or Siemens 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.Check the 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 appliance.WIRING DIAGRAMS:Figure 1A: One Circuit.

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 is 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 shall be used only for fire evacuation signalingand not for any other purpose.8. 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.
