General

See figures 6-1 and 6-2

This chapter contains a functional block diagram circuit

The Alarm and Status Modules operate on + 20 V dc

which is supplied directly to the device supply (Vdd)

description of the Alarm and Status Modules. Refer to

regulator and through a filter to the lamp voltage

regulator. The Vdd regulator provides +6.2 V dc for

the applicable block diagrams shown in figures 6-1 and

operation of the logic circuits whereas the lamp voltage

regulator provides 5 V dc for operation of the alarm

6-2 and schematics shown in figures 68 and FO-1 when

lamps. The power supply circuits are protected by fuse

F1.
