Siren with LED Strobe Light - 110dB, IP65

IP65 Siren ENVIROMUX-SRN-BCNL with LED Strobe Light by NTI

In an era where operational interruptions caused by environmental factors such as overheating, humidity, or unnoticed leaks can lead to immense costs, the ENVIROMUX-SRN-BCNL by NTI sets a new standard in alarm technology. 

This compact, weatherproof alarm unit combines a piercing 110 dB continuous tone with an intense LED strobe light flashing up to 300 times per minute – a combination that not only deters intruders but also immediately alerts personnel in noisy or large areas. 

Thanks to its IP65 certification, it withstands dust, water jets, and extreme temperatures from -25 °C to +55 °C, making it ideal for outdoor or demanding industrial environments. Integrated into NTI monitoring systems, it becomes the heart of your preventive alert solution: whether in server rooms where temperature sensors report critical thresholds or in warehouses monitoring humidity, an event triggers an instant alarm. Customers have praised how this siren has prevented costly downtime – for example, when a cooling failure in a data center was promptly detected, avoiding data losses worth tens of thousands of euros.

The ENVIROMUX-SRN-BCNL impresses with its smart 2-wire interface, allowing seamless connection to existing NTI systems without requiring additional power – supplied directly through the base station with 6–15 VDC. 

The rugged housing, made of high-quality material, measures only 74 × 50 × 123 mm and can be mounted flexibly, either in a standard box or surface-mounted using the supplied screws. With a maximum cable length of 305 m, even remote areas can be reached, greatly increasing the scalability of your monitoring network. 

Imagine a production hall with fluctuating humidity levels: as soon as a sensor detects condensation, the deafening tone sounds while the blue strobe light (or red variant) flashes through the mist to warn workers. 

This dual alert mechanism minimizes response times and enhances safety, especially in combination with temperature and humidity sensors. A logistics company reported that the siren prevented mold growth after a nighttime humidity rise in a storage facility, saving inventory and eliminating health risks for staff.

What makes the ENVIROMUX-SRN-BCNL the ultimate choice is its energy efficiency – consuming only 90 mA at 12 VDC – and its seamless integration into NTI’s comprehensive ecosystem, which includes leak detectors, vibration sensors, and more. 

No complicated setup, no maintenance – simply connect and protect. In outdoor environments with rain or snow, the siren maintains consistent performance, and its alarm sound cuts through even high ambient noise. Industrial users praise its durability: even after years of demanding use, the strobe performs flawlessly, and the tone remains loud and clear. Combined with email or SMS notifications from the NTI system, it creates a fully protected environment. 

Whether for small offices or large facilities, this siren transforms passive monitoring into active prevention, saving costs and bringing peace of mind. An IT administrator shared that during a temperature spike in a server room, the alarm not only sounded but also covered blind spots through its visual signal, preventing a total system failure.

Key Benefits of the ENVIROMUX-SRN-BCNL at a Glance

• Powerful Alarm: 110 dB continuous tone combined with 300 flashes per minute – clearly visible and audible even in noisy environments.
• Weatherproof Durability: IP65-rated protection for indoor and outdoor use, resistant to weather and dust.
• Easy Integration: 2-wire connection to NTI ENVIROMUX monitoring systems; adds audible and visual alerts to temperature and humidity monitoring.
• Flexible Installation: Surface or flush mounting with included screws; cable length up to 305 m for large areas.
• Energy Efficient: Only 90 mA current draw; operates from -25 °C to +55 °C – ideal for year-round use.

Practical Use Cases and Success Stories

The ENVIROMUX-SRN-BCNL proves most effective in scenarios where rapid alarms can protect lives, equipment, or the environment. Here are real examples showing its advantages:

• Server Rooms and Data Centers: When temperature thresholds are exceeded (e.g., due to AC failure), the sensor triggers the siren; the strobe light guides technicians straight to the problem, preventing overheating – one datacenter saved €50,000 in hardware.
• Industrial Halls with Humidity Monitoring: High humidity causes condensation; the siren emits a loud alert while the LED light warns operators – one factory avoided hours of production downtime.
• Outdoor Storage and Tank Sites: Combined with oil leak sensors (such as ENVIROMUX-SOD-3M), it sounds an outdoor diesel-leak alarm; a fuel station operator prevented an environmental disaster through immediate evacuation.
• Logistics Centers: Vibration or intrusion sensors trigger the siren; the blue flash penetrates warehouse fog – one shipping company reduced thefts by 70 %.
• Agricultural Facilities: In silos equipped with humidity sensors, it warns against mold; the loud tone alerts farmers, protecting harvests – a farm avoided thousands in losses.
