Natural Gas Detectors

Natural gas alarms must be installed in private dwellings, class A multiple dwellings, and class B multiple dwellings on or before May 1st, 2025.

Are you Local Law 157 / RCNY 908-02 Compliant?

 F & F Supply is offering the DeNova Natural Gas Detector, a no-fuss 10 year battery powered natural gas detector which is fully compliant with LL 157 requirements.

F&F Supply has partnered with Denova Detect to offer the most reliable option on the market for New York City compliance:

  • No Outlet Required: Denova Detect easily mounts to a wall or ceiling with just one screw, avoiding the need for an electrician.
  • Long-Lasting Power: With a 10-year battery, there’s no need to draw power from an outlet.
  • No Cords Needed: Unlike plug-in units, there’s no need for power cords.
  • No Frequent Battery Replacement: Unlike plug-in units, which require a 9V battery replacement every 6 months, Denova Detect offers a “set it and forget it” solution for a full decade.
  • Simple Installation: Building owners, maintenance personnel, or even tenants can easily install these detectors.
  • Cost-Effective: Although the initial cost of Denova Detect may be higher, it eliminates the ongoing expenses associated with electricians, battery replacements, and continuous electricity usage, making it a smart financial and practical choice.
