The term “Annunciator” refers to a device that announces faults or unusual activity coming from a system or process connected to it in electrical and electronic systems.
Alarm Annunciator is a collection of signal lights. By flashing an LED and making an audible buzzer noise, it alerts users to aberrant situations. An annunciator panel is a method for warning operators of alarm circumstances in the plant in industrial process control.
It functions essentially as an audiovisual warning system, highlighting the error or accident as it occurs or even before it does. This is crucial for safety reasons as well, and occasionally a warning appears before a wrong action, alerting the operator to prevent an accident, for example. This is the Alarm Annunciator’s and the Alarm Annunciation System’s fundamental idea.
The Global Alarm Annunciator market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
All level, pressure, flow, and other process switches can be monitored and alarmed using the Vigilante II PD150 alarm annunciator from Precision Digital.
There are two types of these alarm annunciators; the PD154 has four inputs and the PD158 has eight inputs. Relays, float switches, digital outputs, and numerous other discrete (on/off) devices can all be used as inputs for each model.
All typical ISA alarm sequences, including first out indication, can be field programmed into it. Front panel LEDs and an integrated 85 dB siren are used to signal an alarm.
It has a NEMA 4X front, two SPDT relays for devices that are activated by alarms, a wide operational temperature range, and alarm indications that can be seen in the sun.
