Personal Safety Alarm

The Werleo Metal Safe Sound is a compact personal alarm designed for women, children, students and the elderly who may need to attract help quickly. It produces a high-decibel warning from a metal exterior and includes a multi-colour LED light for visibility. The device operates on two CR2025 button cells and offers selectable audio and light patterns. A strap is not supplied with the unit.

Thermals Noise Power

The alarm runs on two CR2025 button batteries, so power draw is minimal and there are no thermal concerns during normal carry. At one metre the siren reaches 92 dB, while close-range output is 125 dB or more. The leaf-shaped buzzer emits three distinct alarm voices and the LED cycles through five light modes without generating noticeable heat.

Sustained Load Behaviour

Holding the side switch for three seconds activates the first alarm tone and a flashing red LED, continuing until the button is released or the batteries deplete. The top switch controls the LED memory function, recalling the last colour after a three-second pause. Extended activation will drain the button cells, after which the unit returns to its default settings when fresh batteries are fitted.

Questions about this item

How do I fit the two CR2025 button batteries when they run out?

Open the battery compartment, insert the pair with the positive side facing up, and close the cover; the alarm returns to its default light setting automatically.

How long do the CR2025 batteries last before I need to change them?

The two cells power the 130 dB siren and five LED modes for months of occasional use; a dimming light or weaker tone signals it is time to swap them.

Can the 130 dB alarm run continuously without overheating?

The metal-bodied buzzer is designed for short emergency bursts; prolonged activation will drain the batteries quickly and may cause the housing to become warm.
