Description

Overview
  • Connected smoke alarm designed for professionals (lessors and property maintenance specialists).
  • Remote maintenance without entering the home.
  • Up to 25 interconnected detectors and accessories per network.
  • Modern, minimalist design to facilitate acceptance by residents.


Main features
  • Connected: remote monitoring and remote maintenance; be alerted in real time to detector faults, low batteries or other critical parameters.
  • Interconnection: when one detector detects fire, all interconnected detectors in the network trigger simultaneously (up to 25 devices and accessories).
  • Air 360° detection technology: exclusive ambient air analysis with large rear openings for fast, reliable analysis.
  • Insect barrier: pest protection grid and reinforced anti-insect design to reduce false alarms caused by insects.
  • Powerful audible alarm: 85 dB at 3 meters to quickly alert occupants.
  • Silence function: stops the alarm and/or places the detector on standby for 3 minutes without removing it from its base.
  • 8-hour beep delay: temporarily silences fault beeps until the detector is replaced.
  • Signal light: discreet LED in standby, powerful in alarm mode.


Connectivity and integration
  • Dual connectivity options: LoRaWAN and Sigfox (dual-band compatibility to extend coverage and ensure continuity of service).
  • Compatible with REMOTE remote control for ceiling-mounted detectors.
  • Compatible with ALERT kit for deaf and hard-of-hearing users (strobe flash and vibrating cushion; relays alerts up to 100 m in open field).
  • API interface and connectors for integration with management software.


Maintenance and lifecycle
  • Includes a replaceable CR123 lithium battery with an expected autonomy of 5 years (battery life may vary depending on conditions).
  • Electronic maintenance certificate: after each maintenance operation a unique certificate is recorded in the product’s secure NFC chip to certify compliance.
  • Digital detector logbook (NAVIXIS): QR Code + application to monitor installations, track maintenance and centralise records for large fleets.
  • Remote monitoring: the detector is initially programmed not to transmit fire alarms; settings can be adjusted and remote monitoring services may be used.


Installation & safety
  • Universal mounting base simplifies replacement without drilling new holes; compact BASE+ option (3 cm diameter) to limit damage to surfaces.
  • Approved 3M adhesive fastener available to install without screws or plugs (CE-certified mounting device).
