want to send an email message to root. At present the arguments that apccontrol recognizes are:

When apcupsd detects an event, it calls the apccontrol script with four arguments as:

apccontrol <event> <ups-name> <connected> <powered>

where:

event is the event that occurred and it may be any one of the values described in the next section.

ups-nameis the name of the UPS as specified in the configuration file (not the name in the EEPROM). For version 3.8.2, this is always set to Default

connected is 1 if apcupsd is connected to the UPS via a serial port (or a USB port). In most configurations, this will be the case. In the case of a Slave machine where apcupsd is not directly connected to the UPS, this value will be 0.

powered is 1 if the computer on which apcupsd is running is powered by the UPS and 0 if not. At the moment, this value is unimplemented and always 0.

apccontrol Command Line Options

apccontrol accepts the following command line options:

annoyme When a shutdown is scheduled, and the time specified on the ANNOYME directive in the apcupsd.conf file expires, this event is generated.

Default — does a printf ‘‘Power problems please logoff.’’ wall then exits.

changeme When apcupsd detects that the mains are on, but the battery is not functioning correctly, this event is generated. It is repeated every x hours.

Default — does a printf ‘‘Emergency! UPS batteries have failed\nChange them NOW’’ wall then exits.

UPS control system specifications

APC UPS (Uninterruptible Power Supply) control systems are vital components for ensuring uninterrupted power supply and protecting critical equipment from power interruptions, surges, or fluctuations. Designed by Schneider Electric, APC UPS systems are renowned for their high quality and reliability. They utilize advanced technologies and features to suit diverse applications, from home offices to large industrial settings.

One of the main features of APC UPS systems is the ability to provide backup power during outages. This is achieved through a battery system that activates immediately when the mains power fails. This seamless transition minimizes downtime and ensures that electronic devices continue to operate, protecting data integrity and equipment lifespan.

Another significant characteristic of APC UPS systems is their intelligent management capabilities. Most models come with PowerChute software, which provides users with real-time monitoring of power conditions and the status of the UPS. This software allows for graceful shutdowns of connected devices during extended outages, thereby preventing data loss and damage to devices.

APC UPS systems also incorporate advanced technologies such as Automatic Voltage Regulation (AVR). AVR technology ensures that the output voltage remains stable by correcting minor fluctuations without switching to battery mode. This not only prolongs the battery life but also provides a consistent power supply to the connected equipment.

Thermal management is another critical aspect of APC UPS control systems. The design often includes efficient cooling systems that prevent overheating, ensuring optimal performance and longevity of the unit. Some models feature EcoMode, which reduces energy consumption and lowers operational costs by working at high efficiency only when battery backup is not required.

APC UPS systems are designed with scalability in mind. Users can easily add more batteries or connect additional UPS units to accommodate growing power needs. Features such as hot-swappable batteries and modular design facilitate easy upgrades and servicing without interrupting power supply.

In terms of connectivity, APC UPS products often feature multiple options including USB, RS-232, and network management capabilities. This enables users to connect remote management tools and integrate the UPS with existing IT infrastructure.

In summary, APC UPS control systems deliver reliability, efficiency, and advanced technology features that cater to a wide array of power protection needs, making them a trusted choice for individuals and businesses alike.
