NFS-320 Trouble Codes

Detector and sounder base address mismatch or the ACPS address is incorrect.

A beam detector is in configuration mode and will not detect fire.

The RAM battery backup voltage is low.

Something has come between the beam detector and its reflector.

The power supply's battery charger is not working properly.

The CO detection element on the detector has six months left until expiration.

The CO detection element on the detector has reached its expiration date.

Indicates activation of a CO conventional detector connected to a monitor module.

The CO element on the detector is not working properly.

The detector is dirty and needs cleaning.

The detector requires cleaning immediately and is a false alarm risk.

The point has been manually disabled.

There is a ground fault on the main or auxiliary power supply.

The auxiliary power supply's battery charge is too high.

The device has returned a response to the panel that the panel did not recognize.

The infrared element is not working properly on the detector.

The auxiliary power supply's battery is low.

The temperature read by a Heat+ or Acclimate detector is too low.

The detector chamber reading is too low or internal elements are failing.

The detector chamber value has dropped below the allowed limit.

Indicative of dust accumulation that is near but below the allowed limit.

Indicative of dust accumulation above the allowed limit.

The device (module or detector) is not responding to the poll.

The device (module or detector) is not responding to the poll.

The module device has an open circuit on its supervised wiring.

Indicates activation of the Photo, Heat, or CO element of a detector.

Indicates activation of the CO element of a detector, which triggers the SUPERVISORY LED.

Indicates activation of the Photo element of a detector, which triggers the SUPERVISORY LED.

The output module or new sounder base lost power.

The power supply is not working properly.

Diagnostic test failed.

The module device has a short circuit on its supervised wiring.

There is an open circuit on the negative side of SLC loop x.

There is an open circuit on the positive side of SLC loop x.

There is a short circuit on SLC loop x configured for Style 6 or 7.

A system condition indicating an off-normal state of a monitored device or subsystem, such as a sprinkler valve or waterflow switch, that requires attention but is not a fire alarm.

The devices are currently initializing.

A system command or status message indicating the control panel is clearing all active inputs, interrupting resettable power, and decoupling from the network for 60 seconds.

There is a communication error with the CRT-2 terminal.

This detector has failed the FACP’s periodic detector test for alarm capabilities.
