The IS-pA1 is a compact, panel mount 90dB(A) intrinsically safe 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.
