To disable the 2-way audio function, program Option
[7A] as '00'.
NOTE:
Option [7A] may be used with any formats
supported by the MLR2E
.
*Option [7B]: 3 Digit Account Codes to Activate 2-
Way Audio - Default [00]
Option [7B] determines which 3-digit account codes
will be able to activate the 2-way audio feature. Pro-
gram the first digits of the desired account codes in
Option [7B].
For example:
To allow all 3-digits account codes between 200 and
3FF to activate the 2-way audio function, program
Option [7B] as '23'.
To allow all 3-digit account codes between 300 and
6FF to activate the 2-way audio function, program
Option [7B] as '36'.
Program Option [04] as '00' to disable this function.
NOTE:
Option [7B] may be used with any 3-digit
account code formats supported by the MLR2E
.
*Option [7C]: Alarm Codes to Activate 2-Way
Audio - Default [00]
Option [7C] determines the range of alarm codes,
which will activate the 2-way audio function. Pro-
gram the first digits of the desired alarm codes in
Option [7C].
For example:
The DRL2E will initiate audio by the account range,
Options [7A] and [7B] or by Option [7C] ALARM
CODE or by both.
If all alarm codes beginning with 6, 7 and 8 are to
activate 2-way audio, program Option [7C] as '68'.
Option [7C] may be used with 10 to 40 Baud for-
mats, DTMF 4/1, 4/2, and 4/3 formats.
Program Option [7C] as '00' to disable this function.
Example:
4/2 format with account code 1234, alarm code 2 on
zone 3. (1234-23)

00 1-2 Yes Alarm code 2 falls within the code
range 1-2.
1-1 00 Yes Account code 1234 falls within the
range 1-1.
2-3 00 No Account code 1234 is outside the
range 2-3.
00 3-4 No Alarm code 2 is outside the range
3-4.
1-2 3-4 No If both are programmed, both
must be good and alarm code 2 is outside the
range 3-4.
3-5 1-3 No Both must be good and account
code 1234 is outside the range 3-5.
1-4 1-5 Yes Alarm code 2 falls within the code
range 1-5, account code 1234 falls within the
range 1-4.
*Option [7D]: Audio Zone Code - Default [00]
Audio zone code is the range of zone codes that will
activate audio. The first digit is the lowest code. The
second digit indicates the highest zone that will acti-
vate audio. Option [7D] may be used with 10 to 40
Baud formats, DTMF 4/1, 4/2, and 4/3 formats.
* Use Options 7A through 7F only with Model
MLR2E CE (not UL Listed).
*Option [7E] Audio RS-232 - Default [00]
This is the code sent to the automation software that
indicates that two-way audio has been initiated. If
this option is set to '00' there will be no audio-initi-
ated message sent to the automation output. If set
to 01, the automation message for audio will be gen-
erated with protocol ID 'S'. If set to 02, the automa-
tion message will be generated with protocol ID '0'.

*Option [7F]: Audio Format Enable - Default [00]
This option gives you the ability to enable and disable
audio for selected formats. A '1' in the formats bit
position will enable the format for audio. A '0' in the
formats bit position will disable audio for the format.

Bit 5
Bit 6
Bit 7
3 Digit pulse format
4 Digit pulse format
DTMF format
Contact ID
SIA format
Modem II format
ITI Format
Westec format
For example:
if the user wants audio to work only for 3-
digit pulse and SIA formats, Option 7F would have to
be programmed as 11 hex which enables bit 0 and bit
4.
Option 80: Kiss-Off to Hang-up Time - Default [1F]
This option determines the delay between Kiss-off
and the release of the line. The hex value pro-
grammed at this location will be converted to deci-
mal and then multiplied by 100 milliseconds to
generate the delay.
For example:
Option 80 = 0A Hex = 10 decimal * 100 ms = 1000 ms
= 1 second delay
Option 80 = 28 Hex = 40 decimal * 100 ms = 4000 ms
= 4 second delay

The DRL2E is a multi-format receiver capable of
sending several handshakes to a dialer. Often it is
important which handshake is sent first. Program
Options [81] through [88] according to your applica-
tions. Handshake Options:

All other frequencies can be programmed using the
first two digits to represent the 3rd and 4th decimal
places.
