Annunciator Module

GENERAL
Figure 1
This module has two independent
annunciator circuits. The circuits
handle fault signals and operator
actions (acknowledge, reset, etc.).
AO-543-01
Annunciator Module
Each circuit is connected to one indication light. Common outputs like an audible alarm are possible in
combination with the KA-549 module.
The module has a number of typical characteristics:
•
•
•
•
•
•
•
Logic-1 or logic-0 fault signal input
DC- and current pulse input
Galvanically isolated inputs
Various annunciator sequences possible (e.g. A, M, F2A, F3A)
First-failure detection
LED and lamp output
Shift register circuit for connection to the communication system
The fault input can be inverted depending on de INVERSE strapping. When using the current pulse input,
a single pulse can be filtered out by using the build-in time delay. The input signal is used to set two
memory circuits. The FIRST (failure) MEMORY and the ALARM MEMORY. Depending on the required
sequence, the reset inputs can be connected to acknowledge and reset push buttons. Flash inputs
determine, in combination with the memory status, the status of the output light/LED.
For first failure detection, AO-543 annunciator circuits are combined in groups by linking their first-failure
input/output. The way first-failure signals are handled, depends on the required annunciator sequence.
The AO-543 module is used in combination with the KA-549 module. The KA-549 contains the flash signal
source and it can handle the (common) claxon pulse signal.
