9. Mic Volume/Automatic Noise Cancelling Mode (#22)
The microphone volume can be set from 1 to 9 (1 = lowest volume setting, 9 = the highest, factory set to 5) by entering the single
digit then the memory location #22. Alternatively the microphone can be placed in the "ANC" Automatic Noise Cancelling mode by
entering 0#22 in programming. With the mic in the ANC mode, when background noise increases the mic gain will automatically de-
crease. When background noise decreases the mic gain will automatically increase. The ANC mode is useful in applications where
the background noise level can change drastically such as a gas car running vs a diesel truck.
10. Speaker Volume (#23)
The speaker volume can be set from 0 to 9 (0 = lowest volume setting, 9 = the highest, factory set to 5) by entering the single digit
then the memory location #23. Alternatively the speaker can be turned off for silent monitoring by entering 0#31 (see Speaker Mode
section 19).
11. Relay Activation Command (#24)
The one or two digit code stored in the Relay Activation Command is the touch tone command that the person being called must
enter on their phone in order to actuate the relay (door strike/mag-lock/gate controller, etc). The code can contain the numbers 0 - 9,
00 - 99, ## or QQ (factory default). To program the code to "##" you must enter Q#Q# #24 in programming. To program the code to
"QQ" you must enter QQQQ #24 in programming. To disable this feature enter #24 without any preceding digits. The code must be
entered while the remote phone is communicating with the Emergency/Entry phone. The Emergency/ Entry phone determines which
direction the touch tone is coming from and only responds to touch tones from the called phone.
12. Relay Activation Time (#25)
The value stored in the Relay Activation Time is the amount of time the relay will be energized after a correct touch tone command
is entered. This two digit number can range from 01 to 99 seconds, or enter 00 for 0.5 seconds. The factory setting is 5 seconds.
13. Relay Mode (#26)
The 2 amp relay contacts can be programmed to one of five different modes by entering 0,1,2,3 or 4 #26 in programming.
0 = Doorstrike Mode. When programmed for Doorstrike Mode the relay will momentarily activate for the preprogrammed relay ac-
tivation time after detecting the correct relay activation command (one or two digit touch tone) from the called party.
1 = Outbound Call Mode. When programmed for Outbound Call Mode the relay will activate continuously for the duration of any
outbound call from the Emergency/Entry phone. This mode is useful for activating strobe lights for Emergency VoIP phones.
2 = Inbound/Outbound Call Mode. When programmed for Inbound/Outbound Call Mode the relay will activate continuously for the
duration of any inbound or outbound call from the Emergency/Entry phone. This mode is useful for turning on IR flood lights for VoIP
phones with cameras, etc.
3 = Doorbell Mode. When programmed for Doorbell Mode the relay will momentarily activate the relay for the preprogrammed relay
activation time on any outbound call from the Emergency/Entry phone. This mode is useful for activating a door chime, etc. When
activating door chimes, a 0.5 - 1 second relay activation time is recommended.
4 = LV-1K Control Mode. When programmed for LV-1K Control Mode the relay will activate continuously while the Emergency/Entry
phone is powered and registered to the SIP server. In the event the unit loses power and/or SIP registration the relay will turn off, ac-
tivating LV-1K's flashing LED and audible beep signals.
14. Relay Activation Tone (Buzz) Volume (#27)
The relay activation tone is a buzzing sound that is heard at the Emergency/Entry phone and in the called phone when the door
strike relay is activated. The tone length will match the relay activation time up to a maximum of 5 seconds. The tone can be pro-
grammed to three different volume settings 1 = Low, 2= Medium, 3 = High in memory location #27. The tone can also be turned
off/disabled by entering 0#27.
15. Audio Detection Sensitivity (#28)
The Audio Detection Sensitivity can be set from 1 to 9 (1 = minimum setting, 9 = the highest, factory set to 5) by entering the single
digit then the memory location #28. Increasing or decreasing the sensitivity may be required in applications where you are making
an outbound call through your VoIP phone system and are relying on analog audio detection of the distant party answering to turn
on the call connected LED and/or play the location ID message on Emergency VoIP phones.
16. In-Band Call Progress Detection (#29)
The In-Band Call Progress Detection can be set to 0 or 1 (0 = OFF, 1 = ON, factory set to 0) by entering the single digit then the
memory location #29. In-Band Call Progress detection should be turned ON in applications where you are making an outbound call
through your VoIP phone system and are relying on analog audio detection of the distant party answering to turn on the call connected
LED and/or play the location ID message on Emergency VoIP phones.
