NFW2-100 Trouble Codes

The control panel has lost primary AC power.

The battery charger on the main circuit board has failed.

The control panel has failed 10 total attempts to communicate with the primary Central Station phone number.

Maintenance alert indicating that a detector is near but below the allowed alarm limit.

Maintenance alert indicating that a detector needs immediate maintenance due to being within 80% of its alarm threshold for 24 hours.

Input points which are disabled do not cause an alarm or any zone activation. Disabled output points are held in the off state. All disabled points are treated as if they were in trouble.

A supervisory condition has been triggered by a duct smoke detector.

This condition indicates a zero impedance from the Fire Alarm Control Panel (FACP) to ground.

Incorrect device code (Type ID) has been programmed for an installed device.

Invalid reply from the addressable device, indicating a hardware problem.

Battery voltage has fallen below the required threshold.

Internal system memory error.

A fault condition (open or short) on Notification Appliance Circuit 1.

The panel does not detect any batteries connected to the system.

This trouble description indicates an open circuit condition on an addressable device or a notification appliance circuit (NAC).

This code indicates a shorted circuit condition on an addressable device connected to the SLC loop.

This condition indicates an open circuit has been detected on the Signaling Line Circuit (SLC) loop or on an addressable device connected to the loop.

A short circuit condition detected on SLC Loop 1.

A condition indicating that a monitored system component is in an off-normal state, such as a sprinkler valve tamper condition.

Indicates a module has failed the testing of its Class A switching relay.

A condition indicating that a monitored component, such as a sprinkler valve, has been moved from its normal state.

Fault detected on the primary telephone line.

Indicates a detector has failed the automatic test operation of its sensing chamber and electronics.

A device type identifier and event code for a monitor module programmed to monitor sprinkler system waterflow switches, representing a high-priority alarm condition.
