An annunciator panel, also known in some aircraft as the Centralized Warning Panel (CWP) or Caution Advisory Panel (CAP), is a group of lights used as a central indicator of status of equipment or systems in an aircraft, industrial process, building or other installation. Usually, the annunciator panel includes a main warning lamp or audible ...
Remote annunciator: a device that connects directly to the panel; the annunciator's main purpose is to allow emergency personnel to view the system status and take command from outside the electrical room the panel is located in. Usually, annunciators are installed by the front door, the door the fire department responds by, or in a fire ...
Coded panels were the earliest type of central fire alarm control, and were made during the 1800s to the 1970s. A coded panel is similar in many ways to a modern conventional panel (described below), except each zone was connected to its own code wheel, which, depending on the way the panel was set up, would either do sets of four rounds of code until the initiating pull station was reset ...
Some call boxes can be wired to a Fire alarm control panel or annunciator to send a signal to a fire station or dispatch center when a fire alarm is activated in a particular building. Telegraph systems do not give any information about why an alarm was triggered, only the box number which tells firefighters where to respond.
It covers alarms from all systems presented to the operator, which can include basic process control systems, annunciator panels, safety instrumented systems, fire and gas systems, and emergency response systems. The practices are applicable to continuous, batch, and discrete processes.
This code was used by building security to determine where the alarm was originating from. For example, consider a pull station in the fourth-floor elevator lobby of an office building with a code of 5-3-1. When the station was pulled, the security officers in the building would look up 5-3-1 in a master list of codes.

The crew-alerting system (CAS) is used in place of the annunciator panel on older systems. Rather than signaling a system failure by turning on a light behind a translucent button, failures are shown as a list of messages in a small window near the other EICAS indications.
