Napco Commercial Platform Advantages

  • Easy Wire Compatibility -SLC controller supports shielded, unshielded, twisted and untwisted wire - ideal for retrofits
  • Longer SLC loop lengths, support more device load each, too
    (see below for distance at maximum device load in alarm/standby each)
  • 10,000ft. #14AWG 6,200ft #16AWG 4,000 ft. #18AWG
  • Support for Legacy and Existing Notification Appliances - One NAC output configurable for 12V for easy retrofit compatibility
    UL Regulated NAC outputs
  • Automatic drift compensation for system's analog smoke detectors
  • Separate 7A NAC Extender – (4) NAC's, may be installed anywhere on the 4-wire bus. Provides universal FACP support.
  • Keypads mount anywhere on the bus and have flash-able firmware – for updates via Quickloader
  • Smoke Obsuration Report -Quickloader device sensitivity report allows the printout of a report for the AHJ listing the current status of all analog smoke detectors in the system including the programmed obscuration level for each device and the actual sensitivity reading for each device. Report is generated in 3 ways- either remotely (uploaded) or locally through notebook PC or use optional onsite printer.
  • Isolated backup battery circuits for Burglary and Fire for EZ backup calculation and AHJ compliance; allows dealer to accommodate separate backup times for burg and fire. This allows burg system to drop out after burg battery depletion, while fire system is maintained and extremely stable for extended period.
  • Full line of UL Commercial Devices for more flexibility & labor-savings Example, Use Gemini Commercial Wireless 2-input module (GEMC-WL-WD2) to convert any UL listed device into a UL wireless device, ideal for sprinkler supervisories or for use with pull stations (mounts on top of wall/conduit or in deep sngle-gang box (plastic).
