There are three Two-Way audio modes of operation:
Transfer: D6x00 transfers the incoming line to another line, a flash operation is performed at end of event signal, the receiver then dials another line which is programmed at "Transfer Phone Number" (see Section Transfer Phone Number. Entries in sections Flash (x 100ms) (3.1.4.18) and Transfer Phone Number (3.1.4.19) are necessary for this mode of operation.
Hold: The D6x00 keeps off-hook status for a programmed period; another control device should take over the line before hold time expires. Entry at Section Hold is necessary for this mode of operation.
Duration: The D6x00 keeps off-hook status until a programmed period expires or terminates by a STOP command via automation or keypad. A regular telephone should be connected in parallel with the incoming telephone line. Entry at Section 3.1.4.1 Duration is necessary for this mode of operation.
The D6600 ONLY performs one of these modes of operation. If more than one is activated, the priority is Transfer Ø Hold Ø Duration.
3.1.4.1 Duration This entry determines how long the D6600 stays on line when it is in the two way audio operation. The time is set in one minute increments. A setting of 0 disables the two-way audio feature.
3.1.4.2 – 3.1.4.17 Digit x Enable The D6600/D6100IPv6 decodes the first digit of the account number to determine when to start two-way audio operations. If the first digit of the account number matches the selection, the two-way audio is activated.
3.1.4.18 Flash With this option programmed for 1 to 20 (x 100 ms), the CPU will first send the two-way audio signal to automation software via RS-232, then the line will be hook-flashed for the pre-programmed duration, and it stays in off hook position for another 5 seconds, then disconnects.
3.1.4.19 Transfer Phone Number The receiver will dial the number programmed here when in a two-way audio session
3.1.4.20 Hold With this option programmed for 01 to 99 seconds, the line card will maintain the off-hook status the pre-programmed duration after the audio event signal is sent to the automation software, in order to have the software-controlled PBX pick up the line, then hang up.
3.1.4.21 Audio Event By selecting alarm event codes, the receiver can control what signals are enabled for two-way audio. If this field is unchecked the event code option will be ignored in the signal filtering process. This option is available for Pulse 3/1, 3/2, 4/1, 4/2, DTMF 4/1, 4/2, 4/3 and Contact ID formats.
Note: This option can also be used in combination with 3.1.4.21 and 3.1.4.22 for enhanced alarm filtering
Two-Way Audio Example Table 1: Two-Way Audio Programming |
Prompt | Value |
3.1.4.3 Account Digit 1 Enabled | 1 |
3.1.4.4 Account Digit 2 Enabled | 1 |
3.1.4.5 Account Digit 3 Enabled | 1 |
3.1.4.21 Audio Event | 2345 |
3.1.4.22 Audio Zone | 36B |
A signal with Table 1’s attributes activates:
- an account number in the range of 1000-3FFFF
- an event code of 2, 3, or 4
- a zone code of 3, 6, or B
A signal must possess all three attributes (account number, event code, and zone code) to trigger a two-way audio session.
For example:
- 4-2 Alarm 123456 activates a two-way audio session
- 4-2 Alarm 123466 does not activate a two-way audio session
3.1.4.22 Audio Zone By selecting zone numbers (last digit), the receiver can control what signals are enabled for two way audio. If this field is unchecked the zone number option will be ignored in the signal filtering process. This option is available for Pulse 3/1, 3/2, 4/1, 4/2, DTMF 4/1, 4/2, and 4/3 formats.
Note: This option can also be used in combination with 3.1.4.21 and 3.1.4.22 for enhanced alarm filtering
