Indoor Selectable-Output Speaker Strobes and Dual Voltage Evacuation Speakers for Ceiling ApplicationsL-Series, red, ceiling-mountable, clear lens, speaker strobe marked "FIRE". Selectable strobe settings: 15, 30, 75, 95, 115, 150, and 177 cd.System Sensor L-Series selectable-output speaker strobes and dual-voltage evacuation speakers can reduce ground faults and enable faster installation with lower current draw and modern aesthetics.System Sensor L-Series of speakers and speaker strobes reduce costly ground faults using a plug-in design and universal mounting plate that allow the installer to pre-wire mounting plates, dress the wires, and confirm wiring continuity before plugging in the speakers. In addition, a protective plastic cover prevents nicked wires by covering exposed speaker components.These devices also enable faster installations by providing instant feedback to ensure that wiring is properly connected, rotary switches to select voltage and power settings, and 7 field-selectable candela settings for both wall and ceiling speaker strobes.The low total harmonic distortion of the SP speaker offers high fidelity sound output while still offering high volume sound output for use in high ambient noise applications.Main FeaturesPlug-in design and protective cover reduce ground faultsUniversal mounting plate with an onboard shorting spring tests wiring continuity before installationNo extension ring requiredField selectable candela settings on ceiling units: 15, 30, 75, 95, 115, 150, and 177Automatic selection of 12- or 24-volt operation at 15 and 30 candelaRotary switch simplifies field selection of speaker voltage (25 and 70.7 Vrms) and power settings (?, ?, 1 and 2 watts)Speakers offer high fidelity and high volume sound output520 Hz +/- 10% square wave tone capable with compatible FACPCompatible with System Sensor synchronization protocolElectrical compatibility with existing SpectrAlert and SpectrAlert Advance productsTamper-resistant constructionUpdated modern aestheticsGeneral InformationName: System Sensor SPSCRL L-Series Indoor Selectable Output Speaker Strobes, Ceiling Mount, "FIRE" Marking, Red, Honeywell International, Inc, System SensorCategory: System Sensor, Fire, Fire Notification Appliances, Speaker StrobesUPC Code: 783863048340Country of Origin: Mexico.
