ANALOG Analog signals have variable values of current or voltage, with
the specific value generally representing some physical parameter such as water
level or pressure. The most common type of analog signal is a 4-20
milliampere current loop, with a transmitter (transducer and associated power
supply) governing the current in a loop. This current is detected by one or
more receiving devices in the loop, such as an optional analog input channel on
a Verbatim autodialer.
AUTOCALL A special test calling function. When Autocall is turned on,
the unit places test calls at regular intervals to provide ongoing assurance of
Verbatim autodialer and phone line operation. See Section 6, “Advanced Pro-
gramming.”
AUTODIALER A device which constantly monitors a set of inputs from
various external sensors, and places outgoing alarm calls when there is an alarm
condition. It also allows inquiry calls.
AUTOEXTEND A unique feature on the Verbatim autodialer which auto-
matically extends the available message recording time as required, selecting
the optimum speech memory rate for the user’s voice message recording. See
Section 4.2.1, “Verifying/Extending Recording Time.”
CALL BACK See Call Forward.
CALL FORWARD The unit may be commanded from the panel or over the
phone, to place a call to a specific phone number. This is called Call Forward-
ing. If the number called is that of the person commanding the call from a
remote telephone, then it is termed Call Back. This is typically done for test
purposes. See Section 5.8, “Dialing Out and Conversing Through the Verbatim
autodialer,” and Section 6, “Advanced Programming.”
CALL OUT The action of the Verbatim autodialer placing calls to outside
personnel or facilities.
CDL (Central Data Logger) The combination of a modem, a serial
interfaced printer and a special Raco-built interface box is called a Central Data
Logger (CDL). A Raco autodialer/RTU may be configured to call and log data
to the CDL printer. CDL RTUs first call the CDL printer to log alarm and
status information then proceed on to calling personnel by voice.
CLOSED CIRCUIT CONDITION One of two possible states of a contact
closure input circuit. Closed Circuit is the condition in which the contacts
complete the electrical circuit connection. Open Circuit is the opposite
condition, in which the contacts do not complete the electrical circuit
connection. The Open Circuit condition is electrically equivalent to having no
connection to the input circuit. A Closed Circuit input will measure zero volts
DC from the input connection to the common connection point. An Open
Circuit input will measure 5 volts DC. The Open or Closed Circuit status may
