Installation guide

IPDP - installation and operating instructions

power output of the loudspeaker, you can use an add-on module with an

amplifier Fermax PBX EA.

6. Loudspeaker connection SPK

7. Microphone connection MIC - attention on the right polarity!!!

8. MIC loudness setting – by the trimmer you set the desired level of loudness

of the microphone.

9. Settings of Echo cancellation. Fermax IP DP door phone panel is a hands-

free telephone. During the phone call the signal from a loudspeaker comes

back to the microphone and it comes with a delay to the calling party (that

is caused by a digital conversion and transmission of the signal). For this

reason the door phone panel is equipped by an echo cancellation circuit. It

is neccessary to pay more attention during the setting of the echo

cancellation circuit. The right setting of echo cancellation means at what

level of sound the mic turns off in Fermax IP DP in order to avoid returning

the delayed sound.

10. Setting of sensor sensitivity on surrounding light. It is valid only for

modules equipped with a camera. If case the surrounding light decreases

below at certain level (it is set by this trimmer), then the camera is

equipped by a white LED diodes for extra illumination. These LEDs are

activated during a phone call only.

11. Green LED – it signals an outgoing call (the door phone panel calls the

destination number or IP address)

12. Yellow LED – it signals an incomming call (there is a call comming to the

door phone)

13. Ethernet connection (UTP cable) – a connection to the computer network.

If you have got a network switch with PoE or a PoE power supply (a box in

the size of a power supply adapter inserted to the input of UTP cable), then

you do not need an extra power supply for operation of the door phone

panel.

14. DIP switch – setting of default values and the mode of Fermax IP DP door

phone via a DIP switch.

1- reserve (unused)

2- mode switching P2P / SIP server

3- basic settings – resets all values to factory settings

except for the memory of numbers

4- sets the starting IP address to 192.168.1.250

All changes show always after turning off and turning on

of the power supply (restart).

The DIP switch 3 and 4 needs to be switched back to

„on“ position after the start of VoIP module. Otherwise after the restart the

set parameters or the new IP address are rewritten back to the default

mode.

15. Output of 12VDC (max. 350mA!). This output is used primarily for

supplying the power to the lowconsumption electrical lock when PoE is

used.
