Sirens (sound alarm devices)

Sirens feature a wide sound spectrum set most of the time between 105 and 130 decibels. They are thus well-suited to alert in very noisy nvironments. These devices are equipped with numerous standardized tones including for example the AFNOR NFS32001 tone.

Signals (visual alarm devices)

There are many types of visual alarm devices (VADs) including fixed lights, flash lights (blinking lights) and rotating beacons, all designed to improve workers safety in hazardous gas environments. We also provide light signal towers available in many colors (red, orange, light, green or yellow) depending on applications. Visual alarm devices that can be installed in many different areas may need different colors for different messages.

Security light backlit panels

These security lighting fixtures are equipped with a buzzer and feature a customizable or standard text. Usually mounted above doors or entry ways, these security signal lights are designed to alert people about entering hazardous areas or to forbid access.

Audio visual combinations

A combined sounder beacon base integrates a beacon and a sounder to form an audible and visual alarm. This kind of device is mainly used to efficiently warn about a fixed gas detector alert and trigger emergency evacuation of the site. Combined security appliances are the most commonly used system as it can, with only one device, respond to multi-alarm requirements of safety regulations.

All of our siren signals & alarm systems are compliant with ATEX guidelines (explosive atmosphere) with the 94/9/CE directive and are vailable in different voltage – from 12 VDC to 240 VAC.
