APPLICATONS AND COMPATIBILITY
The following diagrams provide information with respect to conguring the NAC circuits and the Sounder and Sounder
Strobe appliances for synchronization.
Figure 9: T3/T4 Single NAC Circuit Application
Figure 10: Coded Sounder Application
Figure 11: T3/4 Single NAC Circuit Application
APPLICATION NOTES:
Note 1: FACP determines the alarm source (re or CO) and activates the T3 or T4 tone pattern to the Siemens LF Sounder.
Note 2: Coded mode operation allows the FACP to manage the code pattern by interrupting power to the device and shall not be used
with strobes. Strobes are not designed to be used in coded applications. CONT mode shall be used with the SLFSW device only.
For T3/4 Application, refer to the following Warnings:
WARNING: BOTH NAC 1 AND NAC 2 MUST REMAIN ACTIVE FOR T4 OPERATION.
WARNING: WHEN USING THE T3/4 OPERATING CODE ON SOUNDER AND SOUNDER STROBES, THE DSC WILL PROVIDE SYN-
CHRONIZATION; THEREFORE, THE FACP’s NOTIFICATION APPLIANCE CIRCUITS CANNOT USE SIEMENS PROTOCOL.
Note 4: Siemens LED Low Frequency Sounder Strobe can provide a non-synchronized strobe appliance when connected directly to a
Fire Alarm Control Panel (FACP), or provide a synchronized strobe appliance when used in conjunction with an FACP that incorporates the
Siemens sync protocol, a Siemens Sync Module or the Siemens Power Supply.
NOTE: Refer to the Siemens, Installation Instructions, PN 315-545222-11 Series DSC Synchronization (Sync) Module for additional
information regarding connection of a DSC.
NOTE: Audio silence function is available when using the Continuous, Code 3, and Code 4 settings.
NOTE: When using the SLFSSW and SLFSW 520 Hz Low Frequency Sounder and Sounder Strobes in the T3/T4 mode, connect a standard
NAC circuit to the (+) and (-) Audible Inputs on the DSC. In the T3/T4 mode, the DSC utilizes NAC 1 and/or NAC 2 in conjunction with the
Audible Input NAC signal to actively toggle between T3/re and T4/CO. Refer to theSiemens, Installation Instructions, Series DSC Synchro-
nization (Sync) Module for additional information and wiring diagrams when connecting to a DSC.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a com-
mercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.
Cet appareil numérique de la classe A respecte toutes les exigences du Réglement sur le matériel brouilleur du Canada.
Any material extrapolated from this document or from Siemes manuals or other documents describing the product for use in promotional or
