NTI Smoke Detector with Heat Sensor UL/TAA

Smoke Detector with Built-In Fixed-Temperature 57°C (135°F) Heat Sensor

In times when IT infrastructures and sensitive data form the core of every company, reliable protection against fire and smoke hazards is essential to avoid costly downtime and ensure business continuity. 

Imagine a smoldering ember caused by a defective server or overheated cable developing in your data center or server room – without early detection, this could lead to severe damages, hardware loss, data corruption, and costly repairs. 

This is where the advanced E-SDS-TAA-V2 smoke detector from NTI comes in: this photoelectric sensor combines precise smoke detection with a built-in fixed-temperature heat sensor at 57°C (135°F) that triggers an alarm when a sudden temperature rise occurs. 

It continuously monitors the environment, responding both to smoke particles and heat spikes, giving you valuable seconds to act. Integrated into the robust ENVIROMUX monitoring system, it not only sends local alerts but also triggers remote-accessible email, SMS, or SNMP notifications. With UL certification for top safety standards and TAA compliance for government requirements, this detector is the ideal guardian for critical IT environments – efficient, low-maintenance, and ready around the clock.

The true strength of the E-SDS-TAA-V2 lies in its versatile and robust design, purpose-built for demanding applications in data centers, offices, or industrial environments. 

The photoelectric smoke detector uses advanced optics to detect even fine smoke particles early, while the integrated heat sensor responds immediately at 57°C, identifying rapid temperature rises or overheating that standard detectors might miss. Operating with a voltage supply range of 8.5 to 35 VDC and extremely low current consumption – just 50 µA standby current at 12 VDC – it is energy-efficient and ideal for decentralized installations. The alarm output via a relay (normally open, NO) allows seamless integration with external systems such as sirens or shutdown relays. 

The connection is simple: via screw terminals with a 22 AWG 2-wire cable connected to the digital inputs of the ENVIROMUX system, with cable runs up to 305 meters – perfect for distributed locations. The included 12V/1A power adapter simplifies commissioning, and compatibility with the E-1W expander extends your monitoring options effortlessly. Whether in climate-controlled server rooms or dusty warehouses, this detector adapts to its environment, maintaining accuracy, supported by UL fire safety approval and TAA compliance for international procurement requirements.

Consider a typical scenario in a mid-sized logistics company: 

The central server room hosts the entire warehouse management and customer database, where servers run continuously, and heat generation poses a constant risk. The IT team mounts the E-SDS-TAA-V2 on the ceiling above the racks. 

One night, a loose power cable causes a slight overheating that activates the heat sensor at 57°C – simultaneously, the smoke element detects the initial particles. Within seconds, the relay opens the contact, the LED flashes red, and the ENVIROMUX system sends an email to the emergency admin as well as an SMS to the team. The administrator can remotely isolate the affected power circuit before flames appear. 

By morning: 

No downtime, no data loss – just a quick inspection. Such real-world cases demonstrate how the E-SDS-TAA-V2 not only warns but actively breaks damage chains, reducing downtime from hours to minutes while meeting certifications such as UL and TAA. It transforms potential disasters into controllable events, protecting company assets and ensuring compliance in regulated sectors like finance and healthcare.

Key Features at a Glance

• Dual Detection Technology: Photoelectric smoke sensor for fine particles plus fixed heat sensor at 57°C – detects smoldering fires and rapid heat spikes early, ideal for hybrid threats in IT environments.
• Energy-Efficient Power Supply: 8.5–35 VDC with only 50 µA standby current and 20 mA alarm current at 12 VDC – minimizes power consumption and supports long-life, battery-free operation.
• Reliable Alarm Output: Relay (NO) for easy integration into alarm systems; triggers sirens, lights, or automatic shutdowns – customizable for specific needs.
• Durable Cable Connection: Screw-terminal connection using 22 AWG 2-wire cabling, supports CAT5/5e/6 up to 305 m – suitable for large-scale installations without signal loss.
• Extended Compatibility: Seamlessly compatible with ENVIROMUX E-1W, E-2D/5D/16D, and E-DI2-1W Digital Input Expander – expand your monitoring network with no extra hardware.
• Safety Certifications: UL-approved for fire standards and TAA-compliant for US government procurement – ensures maximum quality and legal compliance.
• Simple Installation and Setup: Includes mounting hardware and a 12V/1A power adapter – install in under 10 minutes, even for small teams.

Applications and Real-World Use Cases

• Data Centers and Server Rooms: Monitors racks for overheating and smoke from failed components. Example: In 2024, a cloud provider in Frankfurt prevented a server fire by detecting excessive heat; the alarm isolated the rack remotely, saving millions in downtime.
• Office Buildings and Co-Working Spaces: Protects open-floor layouts from cable fires. Example: A Berlin tech startup combined it with temperature sensors; when an air conditioning unit failed, it detected 57°C heat and melting insulation smoke, automatically stopping ventilation – full productivity maintained.
• Hotels and Restaurants: Ideal for monitoring kitchens and storage areas against grease or electrical fires. Example: A restaurant in Munich received an app alert about smoke from a faulty oven; the manager acted preemptively, minimizing damage and avoiding insurance disputes thanks to UL compliance documentation.
• Educational Institutions and Libraries: Secures computer labs and archives. Example: A university in Hamburg installed it above study rooms; it detected smoke from a short circuit and triggered a silent alarm – students continued their work while technicians intervened discreetly.
• Finance and Healthcare: Meets strict compliance such as TAA for government usage. Example: A bank branch in Vienna linked it with PWR-RMT power switches; upon heat alarm, systems rebooted safely – data integrity preserved, audits passed smoothly.

Why the E-SDS-TAA-V2 Is Your Ultimate Protection Partner

Unlike standard smoke detectors, this NTI sensor offers dual intelligence through smoke and heat detection combined with smart integration into the ENVIROMUX ecosystem. It not only issues alerts but stops escalation – from the first heat pulse to safe shutdown. Imagine this in your setup: combined with humidity sensors, it can identify causes like condensation-induced short circuits. Integrated with IP power sockets for automated power management, it creates a self-protecting system. 

For large facilities: multiple sensors can be connected in parallel for zoned monitoring – e.g. rack-to-rack. The compact, dust-resistant design allows discreet installation, and customer feedback highlights its low false alarm rate. With UL approval and TAA compliance, you are protected globally – invest in reliability and turn risks into control.
