Alarms, Line Voltage/Frequency

Definition : Alarms designed to activate audible (i.e., sound) and/or visual warnings when the power line voltage and/or frequency are outside pre-established values (e.g., voltage values plus or minus 5% and/or frequency values plus or minus 0.5 Hz from their nominal values). These alarms typically consist of a battery operated electronic unit that includes electronic circuits that automatically compare the line voltage and frequency with a pre-established range of values; some alarms are interconnected to voltage regulators that can keep the line voltage at useful values when the line voltage is low (i.e., brownouts) or high, and/or activate emergency power units for blackouts or for low or high line voltages that the system cannot regulate. These alarms may be intended for the general power supply of a healthcare facility, a particular area or room in the facility, or specifically for devices whose failure may cause severe consequences to health, a process, or a device. Voltage/frequency alarms are also available as an integral part of environmental and electrical safety monitors and other equipment.
