FUNCTIONAL DESCRIPTION
2.1 INTRODUCTION
This section describes only the functional aspects of the
MFSM. Refer to Maintenance Manual - Volume II for the
accompanying Section 3 - Theory Of Operation. Figure 2-1
presents an overall functional block diagram of the MFSM
major subsystems.
Bold numbers in the following text
correspond to the circled numbers in Figure 2-1.
2.2 SYSTEM CONTROL
The SELCT pushbutton, 1, is part of the System Control
circuit (not shown).
The pushbutton operates a switch
which selects one of four display screens.
The screen
selected is active for programming until the SELCT
pushbutton is pressed again. Only one monitor may be
selected for programming at any time. Then the next screen
in a left-to-right and top-to-bottom sequence is activated.
The VHOLD pushbutton, 10 , allows vertical synch of an
active screen to be corrected.
2.3 SITE MONITOR FUNCTION
The MFSM is patched into the target site's security system.
The MON pushbutton, 2, allows a remote operator to view
what the site monitor operators see as they scan their
system. Because most installations utilize a dual monitor
system, the
MFSM monitor circuits can be switched
between two separate signals, 3, by either pressing the
MON pushbutton again or pressing the
+/-
pushbutton
while in the monitor mode.
