Dual audible and visual alerts: bright LED indicators combined with clear sounds let you know your safety status at any time so you can respond immediately to security events. Adjustable sound output (up to 130 dB): control the noise level to deliver an effective alert without creating unnecessary disturbance in quieter environments. Advanced magnetic sensor technology to prevent false alarms: the sensor remains inactive when the magnet is within a close range of 1 cm, avoiding unwanted triggers from normal proximity. Reliable performance: the combination of visible LEDs and audible tones provides redundant notification so you do not miss critical alerts. Why this helps Immediate awareness: visual and audible signals ensure you see or hear alerts even in noisy or dim conditions. Fewer interruptions: adjustable volume keeps alerts effective while minimizing annoyance in shared or quiet spaces. Reduced false triggers: the 1 cm inactive range prevents routine movements or nearby objects from causing unnecessary alarms. Typical applications Home doors and windows: use on entry points to receive instant notification of unauthorized openings. Retail or storage cabinets: protect inventory and valuables with a visible and audible deterrent that avoids false alarms from close handling. Garages, sheds, or workshops: monitor access points where loud, clear alerts are needed but volume may need to be reduced at times. Key functions and performance summary Alert types: visual (LED) and audible (clear sound) Volume: adjustable, up to 130 dB Falsealarm prevention: magnetic sensor inactive within 1 cm If you need a straightforward notification device that balances strong alerts with falsealarm protection, this unit delivers clear visual and audible signaling plus adjustable volume control and magneticsensor stability.
