A fire alarm annunciator panel is located where it is accessible to fire-fighting crews, such as at building entrances/exits. The annunciator panel will indicate the system status using lamps (or LEDs), an audible warning tone, and depending on the system technology, the exact location or approximate physical location of the source of a fire ...

A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
The teeth would push up on a contact, which would open and close a circuit, pulsing the code to the bells or horns. 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.
Alarm indication signal (AIS) (also called all ones because of the data and framing pattern) is a signal transmitted by an intermediate element of a multi-node transport circuit that is part of a concatenated communications system to alert the receiving end of the circuit that a segment of the end-to-end link has failed at a logical or physical level, even if the system it is directly ...
