Siemens Signalling Devices

siemens signaling devices for plants, lines, and public areas

Clear, unambiguous status signaling keeps operators and maintenance teams in sync with the process. Siemens builds modular towers, standalone beacons, and high-output sounders that wire cleanly in control panels and survive real-world vibration, dust, and moisture. Voltage options span 24 V AC/DC and 115/230 V AC; terminals are finger-safe with captive screws or spring clamps. Lenses and caps use UV-stable polymers so colors stay readable over long duty cycles.

Product range and series overview

Stackable light towers combine base modules, spacer sections, and quick-fit light/sound elements for up to five stages per mast. Single-device units cover compact enclosures, machine frames, and building entries. For hazardous or outdoor zones, sealed bodies and stainless fixings hold rating after repeated cleaning or exposure.

siemens optical signal lights configurations and optics

LED segments come in steady, flashing, and rotating patterns with clear, colored, or Fresnel lenses. Typical luminous intensity is 30–120 cd per tier with lens geometry tuned for 180°–360° visibility. RGB elements allow one stock code to serve multiple statuses; internal drivers keep flicker below camera thresholds in inspection areas. Synchronization lines let multiple towers flash in step for long conveyors.

Other Siemens products

siemens acoustic signal sounders coverage and tone control

Electronic units provide 16–32 tone sets (industrial, evacuation, pulsed) with 2–5 stage priority; output is adjustable from 85 to 120 dB(A) at 1 m depending on housing size. Wide input range and reverse-polarity protection simplify retrofits. High-efficiency drivers minimize current draw on 24 V rails shared with PLC I/O and relays.

siemens beacon lights placement and mounting

Dome, cap, and column formats cover panel doors, machine guards, and wall brackets. Low-profile beacons suit corridors where projection is limited; high-dome versions push vertical intensity for tall equipment. Mounting kits include M20/M25 gland plates, anti-rotation tabs, and vibration pads for presses or packaging lines.

Technical specifications and standards

• Ingress and impact. IP54–IP66 by family; IK07–IK10 for machine areas. Gaskets are field-replaceable; vent plugs mitigate pressure cycling.
• Electrical. 24 V AC/DC, 115/230 V AC variants; surge tolerance typically 1–2 kV line-to-line. Inrush values and steady currents are published for breaker and PSU sizing.
• Optics and sound. LED lifetime L70 ≥50,000 h at Ta; optical SDCM ≤5 to limit color drift across batches. Sounders specify octave-band spectra so designers can predict audibility against ambient noise.
• EMC and safety. Conformity to EN 61000-6-2/-6-3 for immunity/emissions; enclosure ratings to EN 60529; flame behavior and materials documented for panel builders. Fire-alarm-grade families reference EN 54-3/-23 where used as evacuation appliances.
• Environment. Operating −25…+55 °C (model dependent); salt-mist and UV exposure tests available on outdoor lines.

Applications and compatibility

On automated lines, towers map to machine states—POWER, RUN, WARNING, FAULT, SERVICE—so operators read the condition from distance. In logistics halls, high-candela tiers cut through daylight near dock doors. Process skids often require silent visual modes in noise-restricted zones; elsewhere, tone stages escalate from pre-alarm to full stop. For building lobbies and gates, compact heads suit tight soffits without losing side viewing. Where procurement specifies siemens visual and audible indicators in one line item, mixed light-plus-sound modules reduce wiring and I/O count.

Integration with other Siemens products

Light and sound modules land on the same backplates as contactors and PLC I/O, sharing 24 V rails with SENTRON protection and Sirius control gear. DALI/DO gateways or digital outputs from LOGO!/S7 set patterns per recipe or shift. Emergency interfaces tie beacons to fire panels while preserving process states on separate colors; dry-contact interlocks ensure evacuation tones override local alarms. Cable glands, shield clamps, and divider trunking from the Siemens ecosystem keep EMC predictable and IP intact at panel entries.

Selection criteria for B2B clients

Start with the message map: number of states, colors, and whether sound is required. Fix supply voltage and I/O type (steady vs pulsed control lines). Size optical intensity to the viewing distance and ambient lux; select tone spectrum to clear background machinery noise without nuisance. Check IP/IK against the environment and confirm −25…+55 °C operation near ovens or dock doors. For standardized sites, lock lens colors to EN 60073 conventions and use RGB only where variant reduction matters. If the tender mentions siemens sirens and buzzers, pick staged tones with remote volume set and specify dB(A) at the operator position—not just at 1 m. Where a single SKU must cover multiple machines, a tower kit can be ordered as siemens warning signal units with spare tiers for future expansion.

Advantages of working with Bankoflamps

We align each tower or beacon to your cause-and-effect list, then show live EU stock before you fix outage windows. Quotations with EAN/MPN typically arrive around the hour mark and include voltage, optical intensity, tone set, current draw, and mounting code so the BOM matches drawings. Your portal provides real-time lead times, shipment milestones, downloadable price lists, and purchase-history analytics. Approved clients can use post-payment terms up to 30 days. We consolidate by machine cell or floor to cut freight and on-site sorting, hold pricing with validity dates that track project gates, and support teams across France, the Baltics, Germany, Spain, Italy, Belgium, and the Netherlands—your account manager checks IP/IK ratings, PSU headroom, I/O mapping, and color policy against your schematics so crates land panel-ready.
