Remote Annunciator
Why you need a remote annunciator?
This panel has been frequently used in the aviation industry for a long time. In the industrial and commercial setups, the panel lost its popularity but it is regaining its feet in recent times. There are a number of backlit windows available on this panel and each of them is engraved with the name of a specific process alarm. The lights in each of these windows are controlled by switches that are hard-wired.
These lights are arranged in a manner that the lights will begin to work as a particular process condition enters in an abnormal state. These abnormal states can include low pressure, high temperature, loss of the flow of cooling water and various others. The multipoint or single point alarm logic modules operate these window lights while relying on a variety of custom sequences or any of the preselected ISA 18.1.
When the alarm condition is deselected, the window will flash and a bell will sound. This visual and audio assistance is for the operators to take notice of the condition. The operator can easily turn off the alarm but the window will stay lit as long as that particular process is still in the alarm state. As the alarm condition clears up the process state will come back to normal and the light will go out within the window.

Application of remote annunciators
The remote annunciator panels provide the visual and audio data and various other measurement parameters associated with the processes that take place within a site. These panels are equally useful for security, fire alarms as well as manufacturing operations. Many businesses also use these panels for energy management systems along with power distributions systems as well. The annunciators are specified with a variety of zones. These zones include the components or devices that are directly connected with the annunciator panels.
Each of these zoning circuits relay information to the panel and this information is about the current state of any of those initiating devices or sensors. These devices may include heat, smoke, fire alarm, pull station or any other type of circuit closure devices.
The most common applications of annunciator panels are listed as follows,
- Theft or burglary
- Fire
- Security
- Medical
- Machine malfunction
- Process monitoring
- Energy conservation
- Power distribution
- Monitoring of confined space
- Structural failure
- Smoke
- Vehicle safety
A vast array of other proprietary, specialized or unlisted applications.
