Siemens LFS 520 Hz Horn Appliances, Data Sheet

s Sheet Safety Products Appliances 520 Hz Horn Appliances Indoor Overview Powered by 24VDC sound output the 520 Hz Low Frequency Sounders Series LFS contain 520 Hz tone with low current draw Horns are specific to indoor installations Comprised with a modern sleek and aesthetic design Siemens Series LFS has been to comply with the latest requirements for low frequency for sleeping per the National Fire Protection Association NFPA NFPA 72 for FIRE alarm NFPA 720 for Carbon Monoxide CO alarm Applications consist of sleeping areas in residential and commercial occupancies rooms apartments dormitories hotels motels offices Siemens Series LFS has a high quality list of features multiple 520 Hz modes of operation current draw and convenient wall and ceiling mounting Easy adjustment via a finger slide switch found in the outer bottom right corner of each Series LFS appliance for manual field configurable 520 Hz modes of operation Temporal Code 3 FIRE Temporal Code 4 Carbon Monoxide CO Continuous Horn or DSC Control T3 T4 Siemens Series LFS is compatible with the Siemens 50 point 252 point and addressable fire alarm control panels FACPs as well as with FireFinder XLS V FACPs PAD 3 or PAD 4 NAC Extenders Siemens dual sync control DSC modules Designed to meet or exceed NFPA ANSI OSHA standards Restriction of Hazardous Substances RoHS compliant UL 464 Listed and ULC S525 Listed 7135 0067 0277 Approved Industry Inc Technologies Division Series Notification Appliances 2591 Each notification appliance is a Siemens LFS or an approved equal The Siemens Series LFS horn appliances are electronic and have field selectable settings Temporal Code 3 FIRE Temporal Code 4 Carbon Monoxide CO Continuous Horn Temporal 3 or Temporal 4 Dual Sync Control DSC When the selector switch is set for Temporal Code 3 or Temporal Code 4 the sound of the 520 Hz tone is generated from the respective Siemens Series LFS appliance When the selection switch is set to continuous Siemens Series LFS generate a continuous tone with a STEADY 24VDC non coded NAC input Siemens Series LFS can also follow the coded output of the interconnected Siemens FACP The T3 T4 pattern or other pattern must be generated by the Siemens FACP to the system event sent by the panel FIRE or CO Alarm Each 520 Hz sounder is for either wall or ceiling mount installations and is rated at 24VDC Reverberant UL dBA sound pressure measurements on Temporal Code 3 Temporal Code 4 Continuous Horn settings are 76 85 and 80 respectively Anechoic ULC dBA sound pressure measurement on Temporal Code 3 Temporal Code 4 Continuous Horn settings is 80 dBA Anechoic at 24VDC minimum Both models have provisions for standard reverse polarity type supervision and In Out wiring using that accept 12 to 18 AWG wiring with the ability to function between 16 33 VDC Both models incorporate a mounting plate with a snap on grille cover and mount standard electrical hardware requiring no additional trimplate or adapter Removal of an appliance will result in a supervised fault condition by the interconnected Siemens FACP No additional trim plate required for flush mount installs Siemens Series LFS horn appliances are orderable under the following types front plate with no text FIRE text at a setting CO text at a setting or text no specified setting is required The specific text which appears on the outer edges of
