wheeloCk THE SIGNAL SOURCE"" 273 Branchport Avenue Long Branch. NJ 07740 (908) 222-6880 INSTALLATION INSTRUCTIONS MUL TITONE STROBE SIGNALS GENERAL: The Multitone Strobe Signals are UL Listed under Standard 1971 for Emergency Devices for the Hearing Impaired and UL Standard 464 for Audible Signal Appliances. They are listed for indoor use with the backboxes specified in these instructions (See Mounting Options). Models with LS, MS and IS strobes are Listed for wall or ceiling mounting; models with LSM strobes are Listed for wall mounting. The Multitone Strobe Signals use a xenon flashtube with solid state circuitry enclosed in a rugged Lexan- lens to provide maximum visibility and reliability for effective visible signaling, Multitone Strobe Signals can be field set to produce anyone of eight commonly used alarm tones. Sound output can be field set to provide either HIGH (HI) dBA or STANDARD (STD) dBA sound output level. All Multitone Strobe models are designed for use with either filtered DC or unfiltered Full-Wave-Rectified (FWR) input voltage. The Multitone Strobe Signals have separate input terminals for alarm tone activation and strobe activation. Shunt wires are provided to operate both the alarm tone and the strobe simultaneously on a single input circuit (See Wiring Diagram). All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a Fire Alarm Control Panel (F.A.C.P.). & WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT. FAILURE TO COMPLY WITH ANY OF THE FOLLOWING INSTRUCTIONS. CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE. SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS. & WARNING: THE MULTITONE STROBE SIGNALS MUST BE FIa.D SET TO THE DESIRED d;A SOUND OUTPUT LEVa. AND ALARM TONE BEFORE THEY ARE INSTALLED, THIS IS DONE BY PROPERLY INSERTING A JUMPER PLUG AND ADJUSTING A FOUR POSITION SWITCH IN ACCORDANCE WITH THESE INSTRUCTIONS. INCORRECT SETTINGS WILL RESULT IN IMPROPER PERFORMANCE AND MAY DAMAGE THE PRODUCT, NOTE: All CAUTIONS and WARNINGS a,e identified by the symbol &.
