In complex environments like hotels, hospitals, or modern office buildings, a false alarm can be incredibly disruptive and costly. On the other hand, slow fire detection can be fatal. To solve this dilemma, Vigilant presents the Vigilant Intelligent Multisensor Detector, a revolutionary device that thinks before it acts.
This detector doesn’t rely on just one sense; it uses multiple sensors and advanced algorithms to make smarter, faster, and far more reliable decisions.
Three Layers of Detection in One Device
Within a single, compact unit, this detector houses several sensor technologies that work in synergy:
- Photoelectric Smoke Sensor: Reliable for detecting the large particles from smoldering fires.
- Carbon Monoxide (CO) Sensor: Detects CO gas, a key byproduct of combustion. The presence of CO is a strong indicator of a real fire.
- Heat Sensor: Monitors the ambient temperature and detects the rapid, unnatural rise in temperature that signifies a fire.
True Intelligence: Sensor Fusion Algorithms

Vigilant Intelligent Multisensor Detector – This is what makes the detector “intelligent.” Its onboard microprocessor doesn’t just look at one signal; it analyzes and compares the data from all sensors simultaneously.
- False Alarm Scenario: Imagine a cloud of dust from construction work triggers the smoke sensor. A basic detector would immediately alarm. However, the multisensor detector checks: “Is there a rise in CO? Is the temperature increasing?” If the answer is no, it concludes it’s not a real fire and ignores the false trigger.
- Real Fire Scenario: Conversely, a small amount of smoke combined with a slight rise in CO and heat is a classic signature of an incipient fire. The algorithm recognizes this pattern and can sound the alarm faster than a single-sensor device that might be waiting for a higher smoke threshold to be met.
Real Benefits for Your Property

- Superior False Alarm Immunity: Drastically reduces unnecessary building evacuations, business disruptions, and costly fire department responses. This is a massive advantage for hotels and hospitals.
- Faster, More Reliable Detection: Can respond more quickly to a wider spectrum of fire types.
- Installation Efficiency: One device does the job of three separate detectors (smoke, heat, CO). This reduces the number of devices to be installed, saving on wiring and labor costs, and provides a cleaner ceiling aesthetic.
- Life Safety CO Detection: In addition to being a fire indicator, the CO sensor also serves as a life-safety detector for carbon monoxide gas hazards.
Part of the Vigilant Ecosystem
As part of the Signature Series line, this intelligent detector integrates seamlessly with Vigilant addressable fire alarm control panels (like the FX and VM Series), reporting its precise status.In conclusion, the Vigilant Intelligent Multisensor Detector is a quantum leap in detection technology. With its ability to “think” and analyze, it provides the highest degree of accuracy and reliability, ensuring that an alarm is raised only when it’s truly needed.
