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 12 vac power is connected to the system, this switch does
not remove 12 vac power from the unit--it is always present unless the circuit breaker,
which the INSTALLER must supply, is turned off, or the transformer is removed from
the power outlet.
There are six indicators across the topside 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 a fault condition and GREEN for a no-fault
condition, along with a system status indicator which display 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.
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 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 fault status message.
RUN
The RUN key will place the system in a run mode as indicated by the RUN STATUS
indicator. If fault conditions exist, the system will begin placing telephone calls (if
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
system programming including fault modes and tone/dial selection.
SEQUENCE
The SEQUENCE key is a preface key, which allows some of the advanced operation
features of the system to be activated. Until the purpose and use of this key is explained
later in this manual, it is advisable to leave it alone. If this key is randomly operated with
others, a proper keystroke combination could occur, wiping out portions of
telephone number and other data.
ENTER
The ENTER key is used to enter data which the system must use in performing
its monitoring and alarming functions. Included in this data are telephone
numbers, fault messages, the system identification message, the message
count, and the intercall delay.
