L-Series Specifications Architect/Engineer Specifications General L-Series low frequency sounder and low frequency sounder strobes shall mount to a standard 4 x 4 x 1/2-inch back box,4-inch octagon back box,or double-gang back box.Two-wire products shall also mount to a single-gang 2 x 4 x 17/e-inch back box.A universal mounting plate shall be used for mounting products.The notification appliance circuit wiring shall terminate at the universal mounting plate.Also,L-Series products,when used with the Sync•Circuit""Module accessory.shall be powered from a non-coded notification appliance circuit output and shall operate on a nominal 12 or 24 volts.When used with the Sync•Circuit Module,24-volt-rated notification appliance circuit outputs shall operate between 16.5 and 33 volts. Indoor L-Series products shall operate between 32 and 120 degrees Fahrenheit(0°C to 49°C)from a regulated DC or full-wave rectified unfiltered power supply.Low Frequency Sounder strobes shall have field-selectable candela settings including 15,30,75,95,110, 135, 185.The field selectable tones will sound within the frequency range of 520 Hz±10%square wave tone and have a permanent marking on the housing that reads"low frequency sounder". Low Frequency Sounder The low frequency sounder shall be a System Sensor L-Series Model listed to UL 464 and shall be approved for fire protective service.The low frequency sounder and the Sync•Circuitr"MDL3 Module accessory,if used,shall be powered from a notification appliance circuit output and shall operate on a nominal 24 volts(includes fire alarm panels with built-in sync).When used with the Sync•Circuit Module MDL3,24-volt rated notification appliance circuit outputs shall operate between 16.5 to 33 volts.If the notification appliances are not UL 9th edition listed with the corresponding panel or power supply being used,then refer to the compatibility listing of the panel to determine maximum devices on a circuit.The low frequency sounder has an option to switch between temporal three or temporal four pattern,non- temporal(continuous)pattern and coded supply within the frequency range of 520Hz± 10%square wave tone.The low frequency sounder shall operate on a coded or non-coded power supply with high and low volume settings. Low Frequency Sounder Strobe Combination The low frequency sounder strobe shall be a System Sensor L-Series Model listed to UL 1971 and UL 464 and shall be approved for fire protective service.The low frequency sounder strobe shall be wired as a primary-signaling notification appliance and comply with the Americans with Disabilities Act requirements for visible signaling appliances.flashing at 1 Hz over the strobe's entire operating voltage range. The strobe light shall consist of a xenon flash tube and associated lens/reflector system.The sounder shall have an option to switch between a temporal three or temporal four pattern and a non-temporal(continuous)pattern.These options are set by a multiple position switch.The low frequency sounder on low frequency sounder strobe models shall operate on a non-coded power supply with high and low volume settings. The field selectable tones will sound within the frequency range of 520 Hz±10%square wave tone. Synchronization Module The module shall be a System Sensor Sync•Circuit model MDL3 listed to UL 464 and shall be approved for fire protective service.The module shall synchronize SpectrAlert strobes at 1 Hz and low frequency sounder at temporal three.Also,while operating the strobes,the module shall silence the low frequency sounder on low frequency sounder strobe models over a single pair of wires.The module shall mount to a 411/1e x 4t7/16 x 21/8-inch back box.The module shall also control two Class B circuits or one Class A circuit.The module shall synchronize multiple zones.Daisy chaining two or more synchronization modules together will synchronize all the zones they control.The module shall not operate on a coded power supply.
