Federal Signal’s corrosion resistant 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. P-LS2B and P-LS2C loudspeakers 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. Manufactured from corrosion-resistant, anti-static, glass-reinforced polyester (GRP), Models P-LS2B and P-LS2C loudspeakers are designed to accept an audio input of 100Vrms.
Each speaker is transformer coupled with a maximum power output of 25 watts, and is supplied with 10 preset taps (25, 20, 15, 10, 5, 2, 1.5, 1, 0.5 and 0.2 watts) 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.
The bottom surface of the bracket has four slotted mounting holes to further adjust speaker position and adapt to a variety of surfaces. Field wiring connections are readily accommodated by two M20 X 1.5mm threaded openings in the bottom of the rear cover, and terminated via internal terminal blocks. All external hardware is manufactured from corrosion-resistant stainless steel to promote extended service life with reduced maintenance.
