E2S IS-pA1 Intrinsically Safe Panel Sounder

E2S IS-pA1 Intrinsically Safe Panel Sounder

 

E2S IS-pA1 Intrinsically Safe Panel Sounder for Hazardous Area Signalling Applications

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