Description

Security sirens are the first line of defense against intruders and their consequences. After triggering, the device's speakers turn on a pre-programmed sound or backlight, which draws the attention of others to the guarded object and scare off intruders. Modern security sirens have a high frequency sound, with which the alarm signal can be heard several blocks from the place of operation. Some models of security sirens allows selecting melodies with different sound frequencies, which attracts attention even more. Differences between sirens for signaling

  • According to the method of informing about the alarm: sound, light, light and sound.
  • By area of application: outdoor and indoor.
  • By the presence of an uninterruptible power supply.
