8.2.2 Internal IR sensor
There are 2 IR-sensors inside the enclosure.
One is placed vertical on the printed circuit board and has its best function when the
device is placed horisontal on a table.
One is placed horisontal inside the dark IR-glass in the front of the unit. This has its best
function when the device is placed vertically on a wall.
One can choose which IR-sensor to use with the jumper position S150. Refer to chapter 8.2.7
for information about jumper settings.
8.2.3 External IR sensor
0V
0 V.
PWR+
+12 VDC fixed. Intended for IR-sensors and bell buttons. I < 65 mA. It can be
used to supply IR-sensor and to control the door indicator via a door switch, see
chapter 8.2.6.
LED
Controls LED on external IR-sensor(s).
IR
IR-signal from external IR-sensor(s).
1 or 2 external IR-sensors (Picomed IRS, option) can be connected to the terminal strip. They
will be supplied with 0 and +12 VDC together with LED signal from the device. The IR-
signal wires are also connected at the same terminal strip. There is a light indicator placed in
the front of the main PCB which indicates that IR is received. This LED is working in parallel
with the LED indicators for the external IR–sensor(s). Observe that IR-training not can be
done with IR-signals applied to the external IR-sensor(s).
8.2.4 Door phone
A door phone (outdoor unit, option) named Picomed EFP can be connected as the table shows
on the terminal strips DP1 (“Door Phone 1”) and DP2 in Picolo or PicoCombi. Wiring
diagram may be found in the documentation for EFP. DP1 and DP2 are, with exception of
connection D.SW at DP1, equal. They have the following connections with recommended
colours:
