Warning Devices and Sirens

Warning devices and sirens are audible alarm elements that announce conditions such as danger, a fault or the start of a shift with a loud sound and, in some types, with light as well. Motor-driven sirens are used in large, noisy areas such as factories, construction sites and warehouses to give alarm and end-of-shift signals, while illuminated buzzers are used on panels to warn the operator of a fault. This category includes Isıso, Gwest and Konsan motor-driven sirens and illuminated buzzers with 16 mm and 22 mm mounting diameters; models with 24 V and 220 V supply are listed. Choose the device according to the value of the supply voltage and whether it is AC or DC, the sound level (dB) needed to exceed ambient noise, the distance the sound must reach, and the mounting style. A panel-mount illuminated buzzer is meant to warn an operator nearby; it does not replace a motor-driven siren that sounds over a wide area.

How to choose Warning Devices and Sirens

Warning devices and sirens are audible alarm elements that announce conditions such as danger, a fault or the start of a shift with a loud sound and, in some types, with light as well. Motor-driven sirens are used in large, noisy areas such as factories, construction sites and warehouses to give alarm and end-of-shift signals, while illuminated buzzers are used on panels to warn the operator of a fault.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
