Nittan EV-HIOP-BCN High-Output EN54-23 VAD Beacon, 24–38 V DC, IP65 EV-HIOP-BCN

Introduction: Meet the Nittan EV-HIOP-BCN High-Output EN54-23 Beacon

The Nittan EV-HIOP-BCN is a purpose-built visual alarm device (VAD) designed for demanding environments where a highly visible, reliable alert is essential. Engineered for Nittan Evolution analogue addressable fire systems, this wall-mounted beacon delivers a bright white flash that meets EN54-23 Type B coverage requirements and is rated IP65 for exposed indoor or outdoor locations. Available in plain and SCI (short-circuit isolator) variants, the EV-HIOP-BCN combines high-efficiency LED optics, robust communications, and flexible installation options to serve modern life-safety applications.

Key features at a glance

• EN54-23 Type B compliance— designed and rated to meet visual alarm coverage standards for life-safety installations.
• High-output white LED— efficient, bright flashes suitable for noisy or high-occupancy spaces where visual signalling is required.
• EEPROM addressing / FSK protocol— integrates with Nittan Evolution loops for reliable loop communications and easy addressing.
• IP65 ingress protection— suitable for exposed positions such as external walkways, entrances and sheltered outdoor areas.
• Optional SCI variant— built-in loop short-circuit isolator option simplifies circuit resilience in large systems (observe isolator polarity rules).
• Wide supply range— operates from 24 to 38 V DC to suit standard fire system loop power ranges.

Detailed specifications and benefits

Understanding the EV-HIOP-BCN starts with its technical foundations and how those translate into practical benefits on site. The device is designed primarily for loop-addressable systems and carries features tailored to professional installers and system designers.

• Operating voltage:24–38 V DC — compatible with common fire-panel loop voltages and robust against voltage variation on long runs.
• Current consumption:Quiescent ≈200 µA; Alarm ≈20 mA (typical) — low standby draw preserves loop capacity while providing a strong alarm flash when required. Confirm exact figures with the official datasheet.
• Beacon rating / coverage:EN54-23 Type B (W 2.4–7.5 quoted) — designed for specific coverage volumes based on mounting height; use datasheet diagrams to calculate exact placement and spacing.
• Selectable flash settings:The unit supports approved flash patterns to comply with local regulations and to match building requirements.

• Ingress rating:IP65 — protected against dust ingress and low-pressure water jets, making it suitable for exposed or semi-exposed positions.
• Mounting:Wall-mounted design for external and internal exposed locations. Follow manufacturer mounting diagrams for EN54-23 compliance.
• Finish and variations:White lens/body is standard; other colour options (e.g., red) may be available under different part numbers.

• EEPROM addressing & FSK protocol:Addressed on the Nittan Evolution loop for reliable communication and integration with panel logic and monitoring.
• SCI option:Choosing the SCI variant offers built-in loop short-circuit isolation (referenced to EN54-17 where applicable). Important: do not mix isolator polarities on the same loop.
• Installation notes:Must be fitted by qualified personnel in accordance with BS 5839 and local fire regulations. Isolate loop power before wiring; consult datasheets for mounting heights and orientation to ensure EN54-23 coverage.

Use cases and scenarios where the EV-HIOP-BCN excels

The EV-HIOP-BCN is particularly well-suited to environments where audible alarms alone may be insufficient or where visual signalling is mandatory. Typical scenarios include:

• High-noise industrial settings:Factories, workshops and plant rooms where machinery noise can mask sirens and horns. The high-output LED flash provides unmistakable visual cues.
• Public transport and external walkways:Bus stations, train platforms and covered external pathways benefit from an IP65-rated beacon that remains visible in varied weather conditions.
• Large open-plan public spaces:Shopping malls, airports and atria where line-of-sight can vary and a bright Type B beacon ensures alarm visibility across different sightlines.
• Areas with hearing-impaired occupants:Complementing audible devices, the EV-HIOP-BCN makes alarm conditions evident for occupants with hearing difficulties.
• Addressable system installations:Where device-level monitoring and individual fault isolation are required, the EEPROM-addressed Evolution compatibility and optional SCI make it simple to manage devices on the loop.

Comparisons with similar products on the market

When selecting a VAD, key considerations include compliance (EN54-23), ingress protection, output performance, integration with control panels, and installation flexibility. The EV-HIOP-BCN compares strongly across these criteria:

• EN54-23 compliance:Many competing beacons also target EN54-23. The EV-HIOP-BCN’s Type B rating is comparable with other high-output beacons, but installers should always verify coverage diagrams and mounting height recommendations for their preferred model.
• IP rating:IP65 is common among beacons intended for exposed positions; some alternatives offer IP66 or higher for harsher outdoor conditions. Choose based on your site exposure level.
• Addressable integration:The EV-HIOP-BCN’s EEPROM addressing and FSK protocol integration with Nittan Evolution systems gives it an advantage in installations already standardised on Nittan panels. Third-party panels may require conventional beacons or protocol converters.
• SCI option:The inclusion of an isolator variant is a practical benefit in large loops, reducing potential downtime from a single short circuit. Not all competing beacons offer built-in isolators — some rely on separate module installations.
• Power and efficiency:High-efficiency LEDs and low quiescent current are competitive advantages for conserving loop headroom. Some lower-cost alternatives may consume more current or use less efficient optics, affecting overall system sizing.

Customer feedback and installer observations

Official customer reviews for this specific model may be limited in public forums, but installer and system integrator feedback typically highlights a few consistent points for high-output, EN54-23 beacons like the EV-HIOP-BCN:

• Ease of commissioning:Addressable EEPROM addressing and straightforward loop integration reduce time on-site compared with conventional devices.
• Visibility and performance:The bright white LED output and selectable flash settings meet expectations in environments where a powerful visual signal is required.
• Robustness:The IP65 rating and solid construction are appreciated for exposed locations where occasional damp and dust are present.
• Documentation and support:Manufacturers with clear datasheets, EC/UKCA declarations and accessible downloads make planning and compliance checks faster — Nittan’s download centre is cited as a convenient resource.

If you are evaluating this product for a project, request the official datasheet and any site-specific performance data and, where possible, consult peers who have used the device in similar applications.

Conclusion: Why choose the Nittan EV-HIOP-BCN?

The Nittan EV-HIOP-BCN High-Output EN54-23 beacon is a practical, professionally focused visual alarm device that balances compliance, performance and installation flexibility. Its EN54-23 Type B rating, IP65 protection, and addressable Evolution compatibility make it an excellent choice for installations that require a reliable, visible alert in noisy, exposed or high-occupancy environments. The optional SCI isolator variant adds resilience for larger loops, while efficient LED technology keeps current draw low and system headroom high.

In short, if you need an addressable VAD that meets recognised standards, performs well in exposed positions, and integrates cleanly with Nittan Evolution systems, the EV-HIOP-BCN is a strong candidate. Always confirm mounting heights, flash settings and electrical figures with the manufacturer datasheet and engage qualified fire/electrical engineers for installation and commissioning to ensure compliance with BS 5839 and local regulations.
