Reliable and loud alarm system

The Yohii HYD 4218 Active Electronic Intermittent is a game-changing product in the world of electronics. It has an ear-piercing sound that will surely scare off any intruder. One positive feature of this alarm system is the ease of installation; it can be done by anyone without any professional help. However, the downside is that it can be triggered accidentally quite easily. Overall, it's a worthwhile investment for your property's security.

Pros
  • Efficient in reducing pain and inflammation.
Cons
  • Requires a power source for use, making it less portable and accessible for outdoor activities.

Loud pulsing alarm As it should be

There is nothing more to say. It's difficult to find a piezo that doesn't produce a continuous tone. They are "active" which means they have a pulse circuit built in.

Pros
  • Model: HYD-4218, Voltage: 9-15V DC; Rated Current: 12mA; Frequency: 4000Β±500Hz; Noise: 85 dB
Cons
  • Negative impression

These are not intermittent/impulsive beeps!

Sold as an intermittent horn. RG Merc86 and others have established that this is an impulse type. But the ones I got are simple models with a continuous tone, not what I wanted at all. To return!

Pros
  • Package content: 3 pcs. x Active piezo buzzer
Cons
  • Some bugs
