Overview

The Federal Signal P-LS2B is a non-metallic Zone 1 loudspeaker engineered for industrial public address and general alarm systems in hazardous locations. Constructed from corrosion-resistant, anti-static glass-reinforced polyester (GRP), this loudspeaker is certified IP66 for ingress protection against dust and combustible gas. It is ATEX and IECEx certified for Zone 1, specifically for Gas Groups IIB and IIC, ensuring safe operation in potentially explosive atmospheres. The P-LS2B accepts a 100 Vrms audio input and delivers a maximum audio output of 124 dBa at 25 watts, with a wide frequency response from 150Hz to 21kHz. It features transformer coupling and includes 10 preset taps (25W down to 0.2W) for adjustable sound output, allowing precise control over acoustic levels. Installation is facilitated by a stainless-steel ratcheted mounting bracket, which locks the loudspeaker in position. An optional swivel mounting bracket is available for enhanced directional flexibility. Field wiring connections are made via two M20 x 1.5 mm threaded openings in the rear cover, accommodating conductors from 0.5 to 4 mm² (22-12 AWG). All external hardware is stainless steel for maximum corrosion resistance. The P-LS2B is suitable for both indoor and outdoor use, operating in ambient temperatures from -50°C to +70°C (T5 Gb) or -50°C to +55°C (T6 Gb).
