| Bit 1 | Intrusion alarm | Door Open | The door is open. This bit has reverse polarity on Indoor models. In Indoor models, a 1=door open. In Outdoor models a 1=door closed. | The Base Station cabinet detects that the door is not properly shut. | | Check for other alarms that may be present. Visit the Base Station to check the door for physical obstructions and damage that may cause this alarm. The door might have issues pressing down the switch sufficiently to prevent the alarm. If so, try applying some Velcro on the door in front of the switch to ensure that the switch is properly pressed. |
| Bit 2 | Over Temperature Alarm | Over Temperature, Enclosure Temperature 40 degrees C (104 degrees F) or higher, and so on. | The thermostat detects an internal temperature that exceeds the threshold. This bit is not implemented on Indoor models. | This is tripped by a mechanical thermostat in the enclosure measuring air temperature. | Over Temperature for M400B is 70 degrees C/158 degrees F. | Check for other alarms that may be present. Compare the weather forecast and history for the Base Station's location to the alarm threshold. Log in to the Base Station remotely through the Show Terminal option available on the Base Station's page in Network Command Suite to obtain more information. If necessary, visit the Base Station to check for physical obstructions to the AC unit and any damage that might cause this alarm. This alarm may be caused by a clogged air conditioning filter. It is recommended that you bring a replacement filter with you if you need to visit the Base Station to resolve this alarm to prevent return trips. Bits 2 and 3 are mutually exclusive. If both ever become a 1, a FAULT condition is indicated. Base Station Transceivers show a FAULT on the Alarm page if this condition is true. |
| Bit 3 | Under Temperature Alarm | Under Temperature, Enclosure Temperature 5 degrees C (41 degrees F ) or lower, and so on. | The thermostat detects an internal temperature that falls below the threshold. This bit is not implemented on Indoor models. | This is tripped by a mechanical thermostat in the enclosure measuring air temperature. | Under Temperature for the M400B is -50 degrees C/-58 degrees F. | Check for other alarms that may be present. Compare the weather forecast and history for the Base Station's location to the alarm threshold. Log in to the Base Station remotely through the Show Terminal option available on the Base Station's page in Network Command Suite to obtain more information. If necessary, visit the Base Station to check for physical obstructions to the AC unit and any damage that might cause this alarm. Bits 2 and 3 are mutually exclusive. If both ever become a 1, a FAULT condition is indicated. Base Station Transceivers show a FAULT on the Alarm page if this condition is true. |
| Bit 4 | Major Rectifier Alarm | Power System Major Alarm, Power Controller Major Fault, Rectifier Major Fault, and so on. | In outdoor cabinets, this bit is set when the power system in an outdoor cabinet is experiencing an important failure that jeopardizes short-term operation or when there is a malfunction in the emergency fan system. In indoor cabinets and models not equipped with the computerized Cordex or GE/Lineage power supplies, this might be a Fuse Fail alarm. A Base Station can have Major Rectifier and Minor Rectifier alarms at the same time. | In outdoor cabinets, the Base Station detects an important power system failure or an emergency fan system malfunction. In indoor cabinets, the Base Station detects a fuse failure. For all cabinets, this alarm triggers when the batteries fall below 2 hours of available runtime. This bit also may be set during the last 2 hours of an automatic battery test, since the batteries will fall below 2 hours of available runtime. Batteries automatically test themselves every 4 months. | Battery threshold: 2 hours of available runtime. | Check to see if the Base Station is running an automatic battery test. If so, and the alarm clears after the test is concluded, no action is needed. If the Base Station is not running a test, or the alarm does not clear after the test, check for other alarms and visit the Base Station to investigate. If the Base Station has a Cordex power supply, connect to the power supply to run a phase test and obtain more information. |
| Bit 5 | AC Power High/Low Alarm or Fail | AC Power Fail, AC Power Fault, and so on. | This alarm bit generally indicates that the AC power has failed, but can also indicate high-voltage situations. This alarm indicates a power fail on models with the computerized Cordex or GE/Lineage power supplies, and a power supply fail on models not equipped with the computerized Cordex or GE/Lineage power supplies. This is not the same as "On Battery". The enclosures do not currently report "On Battery" unless there is another cause for alarm (typically the case). It is possible to have an AC Fail and On Battery indicate on Bit 5 together, if desired. | The Base Station detects that the AC power input exceeds the high voltage threshold or falls below the low voltage threshold. | AC power input either rises above 135 volts or falls below 90 volts. | Log in to the Base Station remotely through the Show Terminal option available on the Base Station's page in Network Command Suite to obtain more information. If necessary, visit the Base Station to troubleshoot further and make any required repairs. |
| Bit 6 | Minor Rectifier Alarm | Power System Minor Alarm, Power System Noncritical Alarm, Rectifier Minor Fault, and so on. | This bit is only supported by models equipped with the computerized Cordex (Alpha/Argus power supply) or GE/Lineage power supplies. This bit indicates that the power system is experiencing a power system fault that does not jeopardize short-term operation. This bit will also be triggered when the emergency fans are running. A Base Station can have Major Rectifier and Minor Rectifier alarms at the same time. | The Base Station detects a problem with the power supply that does not qualify as a Major Rectifier Alarm event, or the emergency fans are running. | | Most causes of this alarm are not really Minor, and many will lead to a Major fault within 24-48 hours. This alarm should not be disregarded without checking to see what caused it. Log in to the Base Station remotely through the Show Terminal option available on the Base Station's page in Network Command Suite to obtain more information. If necessary, visit the Base Station to troubleshoot further and make any required repairs. Connecting to the power supply, if applicable, may provide more information. |
| Bit 7 | Low Battery | Low Battery, DC power disconnect imminent, and so on. | This alarm indicates that Base Station shutdown is imminent, and is mostly used to put the Base Station into a safe state before disconnecting the power. This alarm will only appear for 60 seconds, and after that all DC power will be disconnected and the Base Station and power controller will go dark. This bit is generated by the custom Low Voltage Disconnect Module on indoor models. This bit is always accompanied by a Major and Minor alarm (computerized models only) due to the conditions that cause the controller to call for a shutdown. | This bit is set when the enclosure batteries are dead and the power controller has committed to a shutdown. | | Visit the Base Station to check the power supply, battery, and general status. If a replacement battery is required, make sure that you are ordering the correct connector type, shape, and chemical composition. |
| Bit 8 | Environmental Control Fault | A/C Unit Fault, Environmental Fault, and so on. Air conditioner equipped Outdoor models only. | For Alpha/Argus models, this bit is set when the A/C unit in the outdoor enclosure sees that the temperature in the condenser or the internal enclosure is too high or low. For Metro models (GE/Lineage), this bit indicates that the system is overheating its condenser. | For Alpha/Argus models: The A/C unit in the outdoor enclosure detects that the condenser temperature is over the threshold, the internal enclosure air temperature is over the threshold, or the enclosure air temperature is under the low temperature threshold. For Metro models (GE/Lineage): This bit indicates High Head Pressure in the air conditioning system. | For Alpha/Argus models: Condenser temperature > 71 degrees C/160 degrees F, internal enclosure air temperature > 57 degrees C/135 degrees F, enclosure air temperature < 1 degree C/34 degrees F. For Metro models (GE/Lineage): Air conditioning system head pressure >350 PSI. | Check for other alarms that may be present. If this bit is not accompanied by either bits 2 or 3, you can safely assume the A/C condenser is overheating only. If accompanied by bit 2, the condenser may be overheating and it is too hot in the enclosure (>40°C/104°F), or the A/C has failed totally and it is Very Hot (>57°C/135°F) in the enclosure. If accompanied by bit 3, you can assume the temperature inside the enclosure is very cold (<1°C/34°F). Compare the weather forecast and history for the Base Station's location to the alarm threshold. Log in to the Base Station remotely through the Show Terminal option available on the Base Station's page in Network Command Suite to obtain more information. If necessary, visit the Base Station to troubleshoot further and make any required repairs. This alarm may be caused by a clogged air conditioning filter. It is recommended that you bring a replacement filter with you if you need to visit the Base Station to resolve this alarm to prevent return trips. |
