Indoor Selectable Low Sounders Low Frequency Strobes Sensor L Series audible visible notification are rich with features guaranteed to maximize with lower current draw and modern aesthetics 520 Hz 10 square wave tone NFPA compliance Full candela range plus High Low tone options to optimize current for a wide variety of applications Compact standard and round ceiling options Field selectable candela settings Wall units 15 30 75 95 110 and 185 Ceiling units 15 30 75 95 115 150 and 177 Rotary switch for High Low Temp3 Temp4 and Continuous Sounder only models also offer a Coded setting Plug in design with minimal intrusion into the back box Mounting plate shorting spring checks wiring continuity before installation Electrically compatible with legacy SpectrAlert and SpectrAlert devices Direct replacement for HW R LF and Compatible with MDL3 sync module Sounders listed for ceiling and wall Round Sounder Strobes listed for ceiling and wall Updated modern aesthetics Listings only 7135 1653 0516 7125 1653 0517 L Series offers the most versatile and easy to use line of low sounder and low frequency sounder strobes in the With white and red plastic housings listed for wall and mounting L Series Low Frequency can meet virtually any requirement low frequency sounder and low frequency sounder strobes were to address the NFPA 72 sleeping space requirements that a low frequency notification appliance that operates within range of 520 Hz 10 and is of a square wave tone Like entire L Series product line they include a variety of features that their application versatility while simplifying installation All feature plug in designs with minimal intrusion into the back making installations fast and foolproof while virtually eliminating and time consuming ground faults further simplify installation and protect devices from construction L Series uses a universal mounting plate with an onboard spring so installers can test wiring continuity before the is installed can also easily adapt devices to a suit a wide range of requirements using field selectable candela settings 24 operation and a rotary switch for 520 Hz low frequency sounder 11 02 2020 Page 1 Specifications Specifications low frequency sounder and low frequency sounder strobes shall mount to a standard 4 4 1 back box 4 inch octagon back or double gang back box Two wire products shall also mount to a single gang 2 4 17 back box A universal mounting plate be used for mounting products The notification appliance circuit wiring shall terminate at the universal mounting plate Also L Series when used with the Sync Module accessory shall be powered from a non coded notification appliance circuit output and operate on a nominal 12 or 24 volts When used with the Sync Module 24 volt rated notification appliance circuit outputs shall between 16.5 and 33 volts Indoor L Series products shall operate between 32 and 120 degrees Fahrenheit 0 to 49 from a DC or full wave rectified unfiltered power supply Low Frequency Sounder strobes shall have field selectable candela settings units 15 30 75 95 110 135 and 185 Ceiling units 15 30 75 95 115 150 and 177 The field selectable tones will sound within the range of 520 Hz square wave tone and have a permanent marking on the housing that reads Hz Frequency Sounder low frequency sounder shall be a System Sensor L Series Model listed to UL 464 and shall be approved for fire protective The low frequency sounder and the Sync MDL3 Module accessory if used shall be powered from a notification appliance output and shall operate on a nominal 24 volts includes fire alarm panels with built in sync When used with the Sync Module 24 volt rated notification appliance circuit outputs shall operate between 16.5 to 33 volts If the notification appliances are not UL edition listed with the corresponding panel or power supply being used then refer to the compatibility listing of the panel to determine devices on a circuit The low frequency sounder has an option to switch between temporal three or temporal four pattern non continuous pattern and coded supply within the frequency range of 520 Hz 10 square wave tone The low frequency sounder operate on a coded or non coded power supply with high and low volume settings Frequency Sounder Strobe Combination low frequency sounder strobe shall be a System Sensor L Series Model listed to UL 1971 and UL 464 and shall be approved fire protective service The low frequency sounder strobe shall be wired as a primary signaling notification appliance and comply with the with Disabilities Act requirements for visible signaling appliances flashing at 1 Hz over the strobe entire operating voltage range strobe light shall consist of a xenon flash tube and associated lens reflector system The sounder shall have an option to switch between a three or temporal four pattern and a non temporal continuous pattern These options are set by a multiple position switch The low sounder on low frequency sounder strobe models shall operate on a non coded power supply with high and low volume settings field selectable tones will sound within the frequency range of 520 Hz square wave tone Module module shall be a System Sensor Sync model MDL3 listed to UL 464 and shall be approved for fire protective service The module synchronize SpectrAlert strobes at 1 Hz and low frequency sounder at temporal three Also while operating the strobes the module shall the low frequency sounder on low frequency sounder strobe models over a single pair of wires The module shall mount to a 411 21 back box The module shall also control two Class B circuits or one Class A circuit The module shall synchronize multiple Daisy chaining two or more synchronization modules together will synchronize all the zones they control The module shall not operate a coded power supply Specifications to 120 0 to 49 Operating Temperature to 93 non condensing Range Hz 10 Range flash per second Flash Rate 24 DC FWR1
