Panel mount sounder

IS-pA1 panel mount sounder, by E2S, is certified II 1G Ex ia IIB T4/5/6 for use in Zones 0, 1 and 2. The IS sounder is suited for use as fault indication or process alarm in control panels located in intrinsically safe environments. It produces a 100dB(A) @ 1m continuous 2600Hz tone that can be pulsed externally to produce different signals.  To reinforce the audible warning signal, E2S also offers the intrinsically safe IS-pB1 panel lights. The high efficiency LEDs, which are mounted behind red, amber, green, blue or clear lenses, have a typical operating life in excess of ten years. Powered via Zener barriers or galvanic isolators, the panel mount sounder and lights produce reliable and cost-effective status indications with minimum power consumption. Edited by: Constanze Schmitz
