Federal Signal’s corrosion resistant loudspeakers, Models P-LS2B-8 and P-LS2C-8, are designed for use in industrial public address and general alarm applications, where corrosion resistance and ATEX/IEC Certification are required. P-LS2B-8 and P-LS2C-8 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.
P-LS2B-8 and P-LS2C-8 loudspeakers are manufactured from corrosion resistant, anti-static, glass-reinforced polyester (GRP). These loudspeakers are rated for 25 watts and designed to accept an audio input of 14.1 Vrms maximum into its 8 Ohm rated voice coil.
Mounting is provided by a “common template” stainless-steel ratcheted mounting bracket that locks the sounder in position at a specific angle without slipping. The bottom surface of the standard mounting bracket contains three slotted mounting holes.
Connection for field wiring is provided by two M20 X 1.5 mm threaded openings in the bottom of the rear cover and terminated via internal terminal blocks. All external hardware is manufactured from stainless steel to resist corrosion and provide serviceability for years to come.
