configured, triggered by the number of failures of the exact same type and data
according to the priority level.

Alarm Relays
The VP 300 provides both major and minor alarm relays, which can be used to light an LED or sound
an alarm. Refer to the Alarm Test section in this chapter.
In the event of a power failure, both of these relays close the contacts to indicate the power failure.
Both relays remain closed during a subsequent restoration of power until the software boot process
opens the relays. However, if there is an alarm condition prior to the power failure or an alarm
condition arises during the boot process, the relay(s) remain closed until the CLEAR H command is
given.
During operation, if any hardware error occurs, the minor alarm relay is closed. In turn, the major
alarm relay closes when an alarm call is attempted, subject to the priority of the hardware errors.

Hardware Error Types
The following table outlines the probable cause and suggested remedy for errors. Clear errors with the
highest priority first. Priority 3 is the highest, 1 is the lowest.
