III. OPERATIONS

A. SYSTEM FAMILIARIZATION AND KEY FUNCTION SUMMARY

The power switch for the system is located on the Front Panel of the system. It is
important to note that when power is connected to the system, and the switch is in the
off position, it does not remove power from the unit. Power is always present unless
the circuit breaker (which the INSTALLER must supply) is turned off or the transformer
is removed from the A/C outlet.

There are six indictors across the top side of the keyboard assembly on the front panel.
These LEDs will indicate the state of the fault channels which the system is intended to
monitor, indicating RED for fault condition and GREEN for a no-fault condition. A
system status indicator displays RED for the HALT mode and GREEN for the RUN
mode.

On the left side of the system front panel is the system speaker. This speaker allows
words the system synthesizes to be heard, as well as telephone line sounds when the
system is on the telephone line placing an alarm call or during a status call placed to the
system.

A Description Of Each Of The System’s Keys And Their Functions Now Follows:

HALT
The HALT key will abort any operation in process, and return the system to the Halt
mode as indicated by the RED RUN STATUS indicator. In this mode, fault conditions
will not be acted upon by the system. However, it is still possible to call the system.
The system will answer the call and deliver the appropriate status message.

RUN
The RUN key will place the system in a run mode as indicated by the RED RUN
STATUS indicator. If fault conditions exist, the system will begin placing telephone calls
(if valid telephone numbers have been programmed into the system). Use of the Delay
key in conjunction with the RUN key will cause the system to execute a delayed entry
into the RUN mode -- which may be programmed to be up to 99 minutes (see the
section entitled “Putting the System in Run” later in this section for more information on
this feature).

MODE
The MODE key is used in conjunction with other keys to effect certain features in the
system programming, including fault modes and tone/dial selection.
