GENERAL:
The Multitone Strobe Appliances are UL Listed under Standard 1971 for Emergency Devices for the Hearing Impaired and UL
Standard 464 for Audible Signal Appliances. The LSM strobes are listed at 15 candela under UL Standard 1971 and meet 75 candela
intensity on axis with low current draw. 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 Appliances 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 Appliances can be field set to produce any one 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 Appliances 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 (FACP).
