Option [3F]: Last Message On
When Option [3F] is enabled, the last alarm message will
be retained on the Line Card display screen until a new
signal is received. Program Option [3F] as “01” to enable
this feature, or as “00” to disable it. If Option [3F] is disabled,
the stand-by message described in Section 1.4 will be
displayed when communication of an event is completed.
Option [40]: Hook Flash
The hook flash feature is used for two-way audio in a PBX
system. The line card can hook-flash the line for 100ms-
900ms programmable to put the line on hold and then
back on line for 3 seconds and hangs up. Program option
[40] to "01" for 100 ms, "02" for 200 ms, etc. "00" will disable
the option.
Options [41] - [46]: Handshake Selection
The DRL2A is a multi-format receiver capable of sending
several handshakes to a dialer. Often it is important which
handshake is sent first. Program Options [41] through [46]
according to your applications. If all six Options are
programmed as “00”, 2300Hz handshake will be sent.
Handshake Options
00 No handshake
01 Dual tone handshake
02 2300Hz handshake
03 1400Hz handshake
04 SIA FSK handshake
06 1600Hz handshake
09 2100 Hz handshake
10 ITI handshake
11 Scantronics dual tone
12 5 sec. pause - 1600Hz kissoff
13 Single Dual tone handshake
14 Robofon handshake
15 Cesa handshake
16 Outel handshake
(Refer to Appendix D for Corresponding Formats)
Option [47]: Handshake and Kissoff Duration
Some control panels have difficulty in understanding the
receiver’s handshake and/or kissoff tones on noisy phone
lines. Option [47] provides a possible solution for this problem
by providing longer constant tones. Program one of the following:
00 1.0 second tone (factory default setting)
01 1.5 second tone
02 2.0 second tone
03 800 ms tone
Note that this option affects only handshakes 02 and 03.
Option [48]: Interval Delay Between Handshakes
The DRL2A Line Card will usually wait for signals from the
control panels for 4 seconds before sending the next
handshake, if there is no signals received. In certain
applications, control panels can not wait long enough to
get their own handshake especially if the handshake is
programmed as the third or fourth handshake.
Program Option [48] with one of the following:
00 4 seconds interval
01 1 second interval
02 2 seconds interval
03 3 seconds interval
Option [49]: 2-Way Audio (Handset) Activation Time
Option [49] determines how long, in minutes, the 2-Way
Audio function will be active once it is initiated. At the end
of this time, the Line Card will hang up the line.
Program a value from “01” to “99” for 1 to 99 minutes. Three
(3) minutes is the recommended length of time for the 2-Way
Audio Activation time.
To disable the 2-Way Audio feature, program Option [49] as
“00”.
Option [4A]: 4-Digit Account Codes to Activate 2-
Way Audio
Option [4A] determines which Account Codes will be able
to activate the 2-Way Audio feature. Program the first digits
of the desired Account Codes in Option [4A]. For example,
to allow all account codes between 1000 and 2FFF to activate
the 2-Way Audio function, program Option [4A] as “12”. To
allow all account codes between 3000 and 6FFF to activate
the 2-Way Audio function, program Option [4A] as “36”.
Option [4A] may be used with any formats supported by
the MLR2-DG. To disable the 2-Way Audio function, program
Option [4A] as “00”.
Option [4B]: 3 Digit Account Codes to Activate 2-
Way Audio
Option [4B] determines which 3 digits Account Codes will
be able to activate the 2-Way Audio feature. Program the
first digits of the desired Account Codes in Option [4B].
For example, to allow all 3 digits account codes between
200 and 3FF to activate the 2-Way Audio function, program
Option [4B] as “23”. To allow all 3 digits account codes
between 300 and 6FF to activate the 2-Way Audio function,
program Option [4B] as “36”.
Option [4B] may be used with any 3 digits account code
formats supported by the MLR2-DG. To disable the 2-Way
Audio function, program Option [49] as “00”.
Option [4C]: Alarm Codes to Activate 2-Way Audio
Option [4C] determines the range of Alarm Codes which
will activate the 2-Way Audio function. Program the first
digits of the desired Alarm Codes in Option [4C]. For example,
if all alarm codes beginning with 6, 7 and 8 are to activate
2-Way Audio, program Option [4C] as “68”.
Option [4C] may be used with 10 to 40 baud formats,
DTMF 4/1, 4/2, 4/3 and Contact ID formats. Program Option
[4C] as “00” to disable this function.
First, to enable the audio feature, the option "[49] AUDIO
MIN." must be programmed. The DRL2A will initiate audio
by the account range, option [4A] and [4B] or by option
[4C] ALARM CODE or by both.
Example: 4/2 format with account code 1234, alarm code
2 on zone 3. (1234-23)
Option Option Switch Reason
[4A]/[4B] [4C] to Audio
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 but alarm code 2 is outside the
range 3-4
3-5 1-3 No Both must be good but 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
