Maximum 1 A current.

(from
manuf.) Voltage from bell button for door phone.
C12 VDC from “+12 VDC fixed” to
this connection.
Picolo and PicoCombi are designed to supply door lock/door opener with 12 VDC. It is also
possible to use external power supply for this purpose. With jumpers on the main board it is
possible to choose between (refer to chapter 8.2.7 for details about jumper settings):

Control door lock with 12 VDC from the device, maximum 1 A current draw.

Control door lock with a N.O potential free relay, maximum 1 A / 32 VAC/VDC.
Tip:

If the outdoor unit EFP is connected to another fixed power supply, then there is a risk of
a “loop” between the speaker and the microphone. This will result in a constant high
frequency tune. When connected to Picolo/PicoCombi’s “DP1/2+” this will normally not
happen.
8.2.5 Multiple indoor units
It is possible to have up to 4 Picolo or PicoCombi's connected to the same telephone line/door
phone line. If more than one Picolo/PicoCombi shall be used, use 1 power supply for each,
and then connect all wires from one to another in parallel both for telephone and door phone.
8.2.6 Door indicator
There is a connection available to control the dørindikator. 0 VDC can be connected from the
terminal strip via a switch in the door, and to the terminal strip. A jumper (refer to chapter
8.2.7 for details about jumper settings) can be used to choose between NO and NC switch.
8.2.7 Jumpers
There are some functions which can be altered when changing place for jumpers on the main
board. The following can be done:
Denomination Short-circuit:
Function
S150 1 and 2 IR receiver in use: the one on PCB.
2 and 3 IR receiver in use: the one glued inside IR-window.
S253 2 and 3 Relay to control door 1 has closed circuit (N.O).
1 and 2 + 3 and 4 Relay to control door 1 supplies door 1 with +12 VDC to
DOR+ and 0 VDC to DOR-. Maximum 1 A.
S254 2 and 3 Relay to control door 2 has closed circuit (N.O).
1 and 2 + 3 and 4 Relay to control door 2 supplies door 2 with +12 VDC to
DOR+ and 0 VDC to DOR-. Maximum 1 A.
S255 1 and 2 When connecting positive voltage, the door indicator will
illuminate.
2 and 3 When connecting positive voltage, the door indicator will
be switched off.
S350 1 and 2 For headset (sound in both speakers in headset).
