The E2S IS-pA1 is a compact, Panel Mount 90dB(A) intrinsically safe Sounder. Producing a high frequency continuous tone, the E2S IS-pA1 can be pulsed to produce different sounds. Utilising the supplied threaded lock nut the E2S IS-pA1 mounts into a 28mm hole – ideal for applications in Control Panels where a fault indication or other process alarm is required.
