Nexelec SAFE+ 3-in-1 Room Sensor

The Nexelec SAFE+ is a 3-in-1 LoRaWAN room sensor that measures carbon monoxide (CO), temperature, and humidity. Designed for lessors, property managers, and building maintenance specialists, SAFE+ provides remote monitoring and real-time alerts for carbon monoxide hazards alongside ambient condition tracking.

SAFE+ combines a 10-year sealed electrochemical CO sensor with temperature and humidity sensing in a compact wall or ceiling-mount enclosure. A digital logbook via QR code tracks installation and maintenance history across large fleets. Unlike the other sensors in the Nexelec range, SAFE+ is not configurable via NFC — it ships ready to use.

Key Features

• Carbon monoxide detection: Electrochemical CO sensor, resolution 1 ppm, range 0–1,000 ppm. Reacts quickly to dangerous CO concentrations and triggers an audible alarm and LED alert to warn occupants immediately.
• Temperature measurement: Resolution 0.1°C, accuracy ±0.2°C, range −30°C to +70°C
• Humidity measurement: Resolution 0.5% RH, accuracy ±2% RH, range 0–100% RH
• 10-year battery life: Two sealed and soldered lithium batteries designed for 10 years of autonomy. No battery replacement required during the product's service life.
• Air 360° detection technology: Exclusive sensing design simplifies sensor maintenance for residents.
• LED status indicator: Three-color LED — Green (operating normally), Orange (maintenance required), Red (CO alert).
• Silence function: Large touch-sensitive button on the front of the sensor stops the alarm or puts the sensor on standby for 10 minutes without removing it from its base.
• 12-hour beep delay: Temporarily silences fault beeps until the sensor is replaced — reduces nuisance calls in rental housing.
• Remote monitoring: CO alarm events, fault alerts, and low-battery warnings transmitted wirelessly. Fire alarms are not transmitted by default; configurable if remote monitoring is required.
• Remote maintenance: Real-time alerts for product faults, low batteries, and other critical parameters — simplifies fleet management across thousands of sensors.
• Digital logbook: QR code on each sensor links to an online logbook tracking installation, maintenance, and replacement history. Integrates with property management software via API.
• Anti-tamper: Lockable mounting base reduces risk of removal in rental housing; alert triggered if the sensor is removed.
• Insect barrier: Integrated pest screen protects the sensing chamber.
• Mounting: Wall, ceiling, or free-standing. Includes compact BASE+ mounting base (30 mm diameter), FLEX free-standing bracket, and FIX 3M adhesive fastener — no drilling required. Universal base compatible with many third-party mounting holes.
• LoRaWAN connectivity: LoRaWAN only (X852LR, 915 MHz)
• End-to-end encryption: Double AES-128 encryption on all transmitted data
• Calibration: Sensor calibration certificate from a COFRAC-accredited independent metrology laboratory
• Certifications: FCC

Applications

• Carbon monoxide monitoring in residential rental properties, social housing, and multi-unit buildings
• Remote fleet management of CO sensors across thousands of homes
• Regulatory compliance monitoring for CO detection in occupied dwellings
• Ambient temperature and humidity monitoring in residential spaces
• Integration with property management platforms via NAVIXIS digital logbook API

Important Notes

• Intended for indoor use only. Operating range: −10°C to +50°C, 10–95% RH non-condensing.
• SAFE+ is not a certified CO detector and is not a substitute for a certified carbon monoxide alarm. Consult the regulations in force in your country regarding CO detection requirements.
• The product is approved for wall mounting at a distance of 30–60 cm below the ceiling for accurate temperature and humidity readings.
• Fire alarms are not transmitted by default. If remote monitoring of CO alarm events is required, the device settings must be adjusted.
• Battery life of 10 years is not guaranteed; actual life may vary. Refer to the "Precautions and Limitations" section of the user manual.
• SAFE+ supports LoRaWAN only at 915 MHz (X852LR). There is no Sigfox variant and no EU868 variant listed.
• LoRaWAN gateway and network server not included. A LoRaWAN network must be available at the installation site.
