Federal Signal P-LS2B and P-LS2C industrial loudspeakers

November 26, 2010 | By Craig Pearson

Federal Signal’s loudspeakers, models P-LS2B and P-LS2C, are designed for use in industrial public address and general alarm applications where corrosion resistance and ATEX/IEC certification are required. They are available in an ATEX/IEC Zone 1 explosion-proof version certified IP66 for ingress of dust and combustible gas to either Group IIB or Group IIC. The loudspeakers are designed to accept an audio input of 100Vrms; each speaker is transformer-coupled with a maximum power output of 25W, and is supplied with 10 preset taps to provide an adjustable sound output range of between 114dB and 124dB (P-LS2B) and 113dB and 123dB (P-LS2C). Universal mounting is provided by a common template, stainless-steel, ratcheted mounting bracket that eliminates slippage by securely locking the sounder in position at a predetermined angle.
