strobe are pre wired to the internal terminal block and the 110 candela strobe is connected to a pair of wire leads The can be wired for one or two speaker circuit operation The strobes are configured for connection to independent notification appliance NAC STH 15SR loudspeaker provides multiple power requirements with high dBA output at each power tap STH 15SR offers a choice of field taps 1 to 15 Watts for either 25VRMS or 70VRMS audio systems The Series STH design incorporates a compression driver mounted a double re entrant horn for maximum output at minimum power across a UL rated frequency range of 400 to 4,000Hz and an anechoic range of to 14,000Hz The speaker line inputs are compatible with standard supervision of circuit wiring by a Voice Control Panel A capacitor is wired series with the multi tap transformer for this purpose Each loudspeaker meets or exceeds the UL Standard 1480 Speakers for Fire Protective Systems RSS 24MCCH and RSS 110R G A B strobes can provide a non synchronized strobe signal when connected directly to a Fire Alarm Control FACP or provide a synchronized strobe signal when used in conjunction with a Sync Module SM or Dual Sync Module DSM The Appliances are UL Listed under Standard 1971 Emergency Devices for the Hearing Impaired for Indoor Fire Protection Service RSS 110R G A B models are not UL Listed The strobes use a xenon flashtube with solid state circuitry enclosed in a polycarbonate lens to maximum visibility and reliability for effective visible signaling All inputs are polarized for compatibility with standard reverse polarity of circuit wiring by a FACP additional information see the Installation Instruction Sheet for the STH 15SR P82697 and the RSS 24MCCH P84442 and Data Sheet for the RSS 110R G A B PLEASE READ

operated within 10 Feet of a person ear they can produce a sound pressure level that the maximum 120dBA permitted by NFPA and OSHA rules Exposure to such sound levels can result in damage to a person hearing Always operate audio amplifiers and speakers within their specified ratings Excessive input may distort sound quality and may audio equipment Do not exceed 130 of speaker input voltage per UL 1480 Improper input voltage can damage speaker If distortion heard check for clipping of the audio appliance with an oscilloscope and reduce the amplifier input level or gain level to eliminate any clipping 3 of 4 Check the installation instructions of the manufacturers of other equipment used in the system for any guidelines or restrictions on and or locating Notification Appliance Circuits NAC
