IS-SB — Intrinsically Safe Sounder Beacon
The IS-SB is an intrinsically safe sounder beacon designed for potentially explosive atmospheres across Group I (Mining) and Group II (Above Ground) applications, in a high-ingress IP66 enclosure. Suitable for fire, security, process-control and general signalling, it combines a two-stage 32-tone alarm at up to 105dB at 1 metre with a DIP-selectable 1Hz flash or static beacon for combined room or zone coverage.
The TimeSaver base lets the head twist and click into place with no extra head wiring.
