SIRENS AND ALARMS
Sirens and alarms are critical components in industrial safety and signaling systems, designed to emit audible and visual warnings in the event of faults, emergencies, or process status changes. These devices typically operate at voltage levels of 12V DC, 24V DC, or 230V AC, with sound pressure levels ranging from 85 dB to 120 dB, depending on t...
Sirens and alarms are critical components in industrial safety and signaling systems, designed to emit audible and visual warnings in the event of faults, emergencies, or process status changes. These devices typically operate at voltage levels of 12V DC, 24V DC, or 230V AC, with sound pressure levels ranging from 85 dB to 120 dB, depending on the model and application. They often feature IP65 or IP66 protection ratings for harsh environments, and may include multi-tone generators, strobe lights, or combined units. In industrial automation, they are used to alert personnel of machine start-ups, conveyor jams, gas leaks, or fire alarms, ensuring compliance with safety standards like EN 54 or ISO 13849.
Sirens and alarms are deployed across a wide range of sectors, including manufacturing plants, oil and gas facilities, chemical processing units, warehouses, and commercial buildings. They are typically installed in control panels, distribution boards, or directly on machinery, and are integrated with PLCs, fire alarm systems, or building management systems (BMS). Common applications include emergency evacuation signaling, process fault indication, and status annunciation for automated production lines.
Our catalog includes subcategories such as electronic sirens, explosion-proof alarms, visual indicators, and combined sounder-beacons. Key article codes include the LE33-24VDC series for standard industrial signaling, the LE33-230VAC series for mains-powered installations, and the LE33-EX series for hazardous areas. The code structure typically follows the pattern LE33-[Voltage]-[Type], where [Voltage] indicates the operating voltage (e.g., 24VDC, 230VAC) and [Type] specifies the model variant (e.g., ST for standard, EX for explosion-proof).
