C.1. Control Module
Conventional reporting devices initiate alarm conditions through the Fire Alarm Control Panel
(FACP). The analog FACP interacts with its reporting devices in a system that is constantly
measuring not only its environment, but also its own ability to report on that environment. The FACP
analyzes the measurements, compares them with other measurements, thresholds, the reported
contamination of the devices, the time of day, and other programmed standards. Depending on the
results of these comparisons, the Analog FACP may initiate an alarm, service, or a trouble condition.
The FACP supervises and responds individually to each analog device in the circuit.
When the analog system configures the polling circuits, the control panel down-loads a number of
parameters, which have been programmed into the panel and are stored in the Central Processing
Unit (CPU), to each analog device. These levels can be altered through the front panel or PC
programming. Each device is programmed for:
•
Alarm Level, High Sensitivity
•
Alarm Level, Low Sensitivity
•
Service Level
The D10024M or D9024M Control Module is the Input/output Printed Circuit Board, beneath which is
the Central Processing Unit (CPU), and the Backplane Board. The Control Module, the On Board
Power Supply, the Transformer, and the input wiring connections are all mounted on a skirt. The
hardware needed to mount the board in the enclosure is attached to the skirt.
