Access Code – a string of DTMF digits that act as a security password
when calling in to a unit with a security level set to two or three. This
string of digits is also required to enter programming mode when calling
in to remotely program a unit.
Accumulator – an input type that keeps a tally of the amount of time an
input is asserted. If the input is de-asserted, the timing stops and resumes
when the input is re-asserted.
Acknowledge Input – an input type that, when asserted, will
acknowledge all existing alarms in the device.
Analog Input, 30V – an input type that monitors a voltage and possibly
has a high and low alarm setpoint with an accepted range on the input
terminal of 0 to +30 VDC.
Analog Input, 5V – an input type that monitors a voltage and possibly has
a high and low alarm setpoint with an accepted range on the input terminal
of 0 to +5 VDC.
Carrier Operated Squelch – an output from a radio that indicates the
receiver squelch is open. This signal is used by the ProTalk Cv3 to
determine when the radio system is busy where it should delay making an
announcement. a.k.a Carrier Operated Relay (COR)
CDMA
– Code Division Multiple Access - a mobile telephony standard
used by carriers such as Verizon Wireless, Sprint Nextel, Bell Mobility,
and Telus Mobility.
Control Code – a string of DTMF digits that are recognized by the unit to
perform an action. Examples of Control Codes include the Acknowledge
Code and an Output On or Off Code. Alternatively, key presses used
when programming are referred to as Program Codes.

Current Input – an input type that monitors the flow of current in a
current loop. This input type may have a high and low setpoint and has an
input range of 4 to 20 mA DC.
