Setting Up And Operation Of The Full Duplex Two Way Voice Function - Assa Abloy S series Installation & Programming Manual

Setting up and Operation of the Full Duplex Two
Way Voice Function
From panel software version V9.05 there have been some new options added to allow for a Full Duplex Two Way Voice
connection following the successful reporting of an alarm event to monitoring. This new two way voice mode applies to
alarm reports in either CID (Contact ID) or SIA. For the new feature to work the panel must have a full duplex voice board
fitted.
There are two new options that determine whether two way voice mode will be active after an alarm and whether the
two way voice connection will be direct on-line (eg staying on-line after reporting the alarm and not hanging-up), or
require a call-back whereby the monitoring room operator must call the panel after receiving the alarm report.
These new options are;
P175E2E option 8
P183E option 5
For direct on-line two way voice option 5 at P183E must be turned on (the setting at P175E2E is irrelevant)
For call-back two way voice option 5 at P183E must be turned off and option 8 at P175E2E must be turned on.
When direct on-line mode is selected the panel will send a CID "606" or a SIA "LF" event code to tell the monitoring re-
ceiver that a listen-in request has been made. This tells the receiver to hold the line open and hand the call over to a tele-
phone so the operator can listen or talk directly to the site where the panel is installed.
If call-back mode is selected the panel will report the alarm in the normal way then hang-up but it will answer any in-
coming calls after 1 ring allowing the monitoring room to call the panel quickly and easily.
There is also an additional feature at P37E option 4 that if selected (option 4 turned on) will disable the output/s while
two way voice is active. This allows internal audible devices to be silenced during the two way voice session. Any output/s
disabled during two way voice by this option will return to normal as soon as the dialler hangs up terminating the two
way voice mode. If the output should still be on when two way voice is terminated it will return to that state. Also in the
case of outputs 1 & 2 only, if they are selected to be modulated outputs (P37E option 1 on) this will also disable the out-
puts during two way voice mode.
OPERATING MODE
Regardless of whether the mode is set to direct on-line or call-back, once two way voice mode is active the panel will gen-
erate a short beep every 5 seconds for a 30 second period. If nothing happens and the 30 second timer expires the panel
will hang-up.
If however the DTMF code programmed at P175E14E is entered before the 30 second timer expires (eg if a code of 1234
was programmed at P175E14E then the operator must enter 1-2-3-4-# at their telephone). The short beeps will stop and
the two way voice channel will remain open for a period of 3 minutes (if no code is programmed at P175E14E then press-
ing the # button is all that is needed).
After 2 minutes and 30 seconds the short beeps will start again. The operator must repeat the process above to keep the
panel on-line for a further 3 minutes otherwise the panel will hang-up when the 3 minutes expire.
If the operator wishes to terminate the two way voice connection they should enter in 0-0-0-# on their telephone which
will tell the panel to hang-up.
If the panel is set for two way voice call-back operation it will answer any in-coming call on the first ring for a period of 10
minutes from reporting the alarm event and hanging up. If the DTMF code at P175E14E (as described above) is not en-
tered within 30 seconds and the panel hangs-up, the panel will still answer any new calls on the first ring unless it has
been longer than 10 minutes since the original alarm was transmitted. As soon as the panel receives the correct DTMF
acknowledge code the auto-answer feature (answering on the 1st ring) will be reset.
