Reliable Fire Protection: The Interra ITR403-1001 KNX Smoke and Heat Detector
The safety of modern smart buildings depends on the quality of integrated security devices. The KNX Smoke and Heat Detector by Interra (Model: ITR403-1001) represents a pinnacle in fire safety technology. As part of the professional range of KNX Products available at KNXbazzar, this dual-sensor device ensures that your home or office is protected against both smoldering smoke and rapid heat increases.
In this guide, we will explore the technical capabilities, installation benefits, and integration features of the ITR403-1001, and why it is a must-have for any KNX-based automation project.
Why Choose a KNX Smoke and Heat Detector for Your Project?
Fire safety is not an area where property owners should compromise. Standard battery-operated detectors often fail due to dead batteries or lack of connectivity. However, the Interra ITR403-1001 KNX Smoke and Heat Detector is fed directly from the KNX bus. This means it is always active as long as the system is powered, eliminating the need for external power supplies or frequent battery changes.

Dual Detection Technology
Unlike basic detectors that only look for one sign of fire, the ITR403-1001 senses both heat and smoke. This dual-sensing capability significantly reduces false alarms while ensuring that different types of fires—from slow-burning upholstery fires to high-heat chemical fires—are detected immediately.
Key Features of the Interra ITR403-1001
Interra is a world-renowned brand known for its innovative KNX Products. The ITR403-1001 model carries this reputation forward with several key features:
- Bus Powered Efficiency: It draws power directly from the KNX line, simplifying the wiring process.
- Early Warning Notifications: In the event of an emergency, the device sends telegram values to the KNX bus. This allows for instant notifications to be sent to your mobile phone or touch panel.
- Twist-Lock Mounting: Installation is made simple and secure with a professional twist-lock system, reducing labor time during site setup.
- Tamper-Resistant Design: The physical build of the detector is designed to be safe from unauthorized removal or interference, ensuring long-term reliability.
- Acoustic Alarm: In addition to digital notifications, the product features a high-decibel internal siren to alert occupants locally.
Integration with KNX Products and Ecosystems
The true power of the ITR403-1001 lies in its ability to communicate with other KNX Products. When the KNX Smoke and Heat Detector identifies a threat, it doesn’t just sound an alarm; it can trigger a “Safety Scene” across your entire building:
- Lighting: Automatically turn on all lights to clear escape routes.
- Shutters: Open all motorized shutters to allow for emergency exits and smoke ventilation.
- HVAC: Shut down air conditioning units to prevent the spread of smoke through ventilation ducts.
- Notifications: Send an emergency signal to the building manager or a security center via the KNX bus.

Installation and Maintenance
The ITR403-1001 KNX Smoke and Heat Detector is designed for the professional installer. Thanks to the twist-lock base, the wiring can be prepared in advance, and the detector head can be attached once the construction dust has settled. This protects the sensitive optical sensors from being contaminated during the final stages of building.
As a high-end Interra brand product, it requires ETS (Engineering Tool Software) for configuration. Integrators can set different threshold levels for heat and smoke based on the specific requirements of the room (e.g., higher thresholds for kitchens compared to bedrooms).
