2.2.1 Electrical connections
The IR-receiver shall be powered by 12-24 VDC/AC and shall only be connected to approved
powersupplies.
All connections shall be made without an active powersupply. The minimum cable area shall
be 0,22 mm

.
If necessary, it is possible to connect an additional IR-sensor to the IR-receiver. Also two IR-
receivers can be connected together, and work as IR-sensors for each other. An IR-signal will
be adducted to the other IR-receiver via the IR-bus. The IR-sensors have to be programmed
with the same user code. The IR-bus has 4 connections:
1.
IR-BUS signal.
2.
Ground (-).
3.
IR-BUS LED.
4.
=< + 24V.
To connect different receivers to each other, they have to use the same powersupply.
2.2.2 Wiring

2.2.3 IR-receiver with lock-code
Picomeds IR-receivers are designed to work together with Abloy and Picomatic dooropeners.
Usually these advanced door-openers will be connected to only one relay-output. When the
IR-receiver is programmed with a lock-code signal, it will activate both relay 1 and 2. The
signal on output 2 will be activated a little bit before channel 1, and it is ment for lock-
systems which not can be controlled by the dooropener.
2.3 Programming
The ER2AC and ER4AC IR-receiver can be programmed by the 2 push-buttons next to the
LED on the PCB. It is also possible to use these buttons in combination with a
preprogrammed IR-transmitter and obtain a fast-mode programming. The front-cover has to
be removed to get access to the buttons. The power supply has to be connected to the IR-
receiver, but no electrical components shall be connected to the relay connections. The
receiver will not loose any settings during a power loss.
