CIRCUIT DESCRIPTION
F
ig. 1 shows the 46019 Summary Alarm Module functional
schematic. Here is a brief description of each of the func-
tional parts of the circuit:
TTL/Optically Coupled Inputs
A standard TTL input and an optically coupled (OC) input
represent each alarm level (A, B, C and D). Either input drives
the latch and gate circuit which operates the relay coil repre-
senting that input’s level and the common coil.
Latch/Gate Circuit
The TTL or OC input enables the latch and gate circuit for each
of the four inputs. Output from the latch and gate circuit drives
the relay coils and individual LEDs for indicating:
♦
A new alarm (NEW)
♦
Existing alarm (EXIST ALARM)
♦
The operation of the common relay output (COMM RLY).
