Key benefits Immediate, visible and audible notification of power interruptions so you can act before equipment is damaged or product is lost. Loud 120 dB (or higher) alarm ensures staff notice failures even in noisy environments; a manual mute option lets you acknowledge the alert without disabling monitoring. Designed to tolerate higherthanstandard supply voltages, so it continues to protect connected equipment reliably under variable power conditions. Main functions and performance LED indicator shows power output, powerfailure alarm and current power status at a glance. Audible alarm delivers up to 120 dB (or more) during a power cut and sounds continuously until power is restored or the alarm is manually muted. voltage tolerant design allows the unit to operate safely and reliably even if incoming supply voltage exceeds typical nominal levels. Compatibility and applications Built for use with freezers and refrigerators and suitable for monitoring critical power to other equipment. Common installation environments include telecom rooms, hospitals, farms, industrial and mining sites, facilities and stations. Reliable option for any setting where uninterrupted power is critical and fast staff response to outages is required. Practical use scenarios Freezer/refrigerator monitoring: Alerts staff immediately if a freezer loses power so perishable goods can be checked and protected. Telecom or data rooms: Notifies onsite personnel of power loss to avoid extended downtime and to prompt backup power activation. Hospitals and industrial facilities: Provides audible and visible alerts to protect medical refrigeration and industrial processes when mains power is interrupted. What it solves Reduces risk of loss from unnoticed power failures by providing a clear, loud alarm and visible status indication. Supports quick human response without requiring constant manual checks, improving asset protection and operational continuity. Notes Functions described: LED status indication, 120 dB+ alarm with manual mute, and voltage tolerant design. Suitable for the listed environments and equipment types; use as part of your facility's powermonitoring and response procedures.
