Operation: Respond to Alarms
42 NetworkAIR IR Operation, Maintenance, and Troubleshooting
Env Temperature Low • Verify that no supply air is fed directly back into the return air.
• Ensure that the alarm delay is not set too low. The delay should be long
enough to allow the room temperature to stabilize after start-up.
• Verify that the temperature alarm threshold for the environmental (return or
remote) sensors is below the cool and reheat setpoints.
• Verify that the Module is configured and equipped for the reheat mode.
• Ensure that the reheat mode is enabled (if your Module is equipped with
reheat).
• Ensure that the reheat mode is not disabled because of an active user-defined
input mapped to nonessential lockout.
Fire Detected • Follow the appropriate facility emergency protocol. N
OTE: The purpose of
the fire sensor is to warn you of possible equipment damage. It is NOT
intended to provide a fire alarm system to protect the facility and the lives of
its occupants.
• Confirm that the wiring connections are secured to the wiring harness.
• Verify the setting of the fire detector (fire stat).
• Replace the fire detector (fire stat).
Fluid Coil Actuator Fail • Verify that the connections between the actuator and the controller board are
correct and securely tightened.
• Confirm that the control voltage and signal voltage reach the actuator.
• Ensure that the proper Module configuration is defined for this Module,
especially that the coil configuration and the actuator type are correct.
• Replace the Coil Fluid Actuator.
Group Configuration Invalid • Check that the # Systems setting (Path: Main > Setup > Group > Group
Config) agrees with the actual number of Systems connected to the Group.
Increase this setting to match the number of connected Systems.
Group Configuration Conflict • Verify the Group configuration settings (Path: Main > Setup > Group) are
correct. The Group detected one or more Systems in the Group to have
different Group configuration settings and changed that System’s settings.
Group Fatal Fire Shutdown • Check the Systems in this Group for fire alarms. The Group Fatal Fire
Shutdown occurs only when the Group Fire Alarm configuration setting
(Path: Main > Setup > Group Config > Grp Fire Alrm) is On. While the
fire alarm is active, the Group will remain shut down.
Group Fatal Smoke Shutdown • Check the Systems in this Group for smoke alarms. The Group Fatal Smoke
Shutdown occurs only when the Group Smoke Alarm configuration setting
(Path: Main > Setup > Group Config > Grp Smoke Alrm) is On. While
the smoke alarm is active, the Group will remain shut down.
Heater Requires Maintenance • Verify the operation of the heater and perform preventive maintenance.
• Reset the maintenance alarm on the display interface for the heater.
Humidifier Current High • Verify that the proper voltage is applied to the humidifier cylinder.
• Confirm that the line voltage connections to the cylinder are secure and
correct.
• Ensure that the humidifier water supply has not been conditioned.
Conditioning can increase the water conductivity.
• Check the humidifier cylinder for mineral buildup that bridges the electrodes.
• Check the fill and drain valves for leaks.
