EMAS MBZS220SE - 85dB Alarm LED Buzzer Alarm Indicator 22mm (IP65 230V AC)

MB Series Plastic with LED 230V AC 22 mm Buzzer The MBZS220SE combines an 85dB audible alert with a visual LED cue in a sealed IP65 housing — the SE designation marks the enhanced-seal, washdown-rated version of the standard MBZS220S. It's built for wiring straight to a relay alarm output on temperature controllers and other process devices, and is a natural pairing with Novus controllers where washdown protection is needed. It can also be housed in one of our PY Series control boxes for a self-contained panel-mounted alarm unit. This is a one piece device suitable for a combined audible and visual alarm. Perfect for wiring to a relay alarm output on temperature controllers and other process control devices. Recommended for use with our range of Novus controllers.

This SE version has an enhanced seal giving IP65 protection, with a slightly lower 85dB volume compared to the standard MBZS220S's 90dB at IP50. Choose this for washdown or outdoor-adjacent mounting. Can I wire this directly to a temperature controller's alarm relay output? Yes — it's commonly paired with Novus controllers (a separate brand we also stock), wired directly to the alarm relay's mains output. Is this suitable for washdown or outdoor mounting? Yes — IP65 rated, protected against dust ingress and low-pressure water jets, making it suitable where the standard MBZS220S (IP50) would not hold up. What's the difference between this and the 24V MBZS024SE? This is the mains-voltage variant, suited to circuits already switching 230V AC directly. If your control circuit runs on 24V AC/DC, use the MBZS024SE version instead. Industry Applications Process instrumentation — washdown-rated alarm annunciation wired to temperature controller or PID alarm relay outputs Food & beverage processing — combined audible/visual alarm that survives regular washdown cycles Water treatment & utilities — audible/visual signalling in wet or humid plant environments
