Microtel Series 250 - Manual (Page 20)

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, an unintentional yet valid keystroke combination could occur,
deleting portions of programmed telephone numbers 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.
MESSAGE
The MESSAGE key is used in conjunction with others to program the message for each
fault channel, and the system identification message. Additionally, depression of the
MESSAGE key alone when the system is in the HALT mode, will cause the current ID
and status messages to be articulated by the system.
READ
The READ key is used to recall any of the programmed information.
DELAY
The DELAY key has four functions:
1. When used in telephone number programming, it inserts a short pause
between digits in a telephone number.
2. When used with the ENTER key, (i.e. ENTER, DELAY, 0) it sets the intercall
delay time; that is, the time the system will wait after its call out message has been
acknowledged before it begins placing regular calls again (see section II E-4 of this
manual for additional information).
3. When the DELAY key is used with the RUN key, (DELAY, RUN) it allows
delayed, automatic entry into the RUN mode.
4. When the DELAY key is used for fault delay time programming, it allows the
entry of integration or delay times for the detection of each fault condition.
DIGITS 1 THROUGH 0
The digit keys are used for numeric entry of data values and data locations.
* KEY
The * key is used as an entry location for ring count programming. The ring count is the
number of incoming telephone rings which the system will count before answering and
servicing the incoming call. (See Section II E-1 of this manual for more information)
