The IS-pA1 panel-mount sounder is ideal for use as fault indication or process alarm in control panels located in intrinsically safe environments.

Certified II 1G Ex ia IIB T4/5/6 for use in Zones 0, 1 and 2, the IS produces a 100dB(A) at 1m continuous 2,600Hz 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 10 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.

The E2S IS range also includes the IS-mini sounder, beacon and combined units, as well as the IS-L101L LED beacon and the IS-A105N sounder, which are approved to Atex, IECEx and FM.
