1.2 Safety rules
Note: Incorrect wiring of this product can damage the product and lead to other hazards.
Make sure the product has been correctly wired before turning the power ON.
Before wiring or removing/mounting the product, be sure to turn the power OFF. Failure to
do so might cause an electric shock.
Do not touch electrically charged parts such as power terminals. Doing so might cause an
electric shock.
Do not disassemble the product. Doing so might cause an electric shock or faulty
operation.
Use the product within the operating ranges recommended in the specification (voltage,
shock, mounting direction, atmosphere etc.). Failure to do so might cause a fire or faulty
operation.
Firmly connect plugs to the terminals. Insufficient connection of the plugs might cause a
power failure and communication problems.

2Power supply and Communication
The Room Panel iSMA-B-LP can be powered with 24 V AC/DC. Power consumption
depends on power supply voltage type used and CO2sensor presence (see Technical
specification table). There are two RJ12 sockets mounted on the back side of the Room
Panel (Figure 2). Each RJ12 socket has the same internal connection and functionality.
Two RJ12 sockets allow for using in and out connections for other devices in the network.
Power supply can be connected through the RJ12 connector as shown in Figure 3 below.
Figure 2 RJ12 sockets in the back side of the Room Panel
There are two pairs of pins for 24 V AC/DC power supply connection (+24 V DC pins 5 and
6, -24 V DC pins 1 and 4). These pin pairs can be used freely. It is especially useful when
different types of connection cables are used (4 or 6 core). It is possible to use single
cable with RJ12 connectors for power supply and RS485 communication. Pins no. 2 and
3 are dedicated for RS485 communication connection. Communication bus should be
connected as shown in Figure 6.
The Room Panel exchanges data with other devices through Modbus protocol
(RTU/ASCII) and BACnet MS/TP.
Figure 3 RJ12 socket pin configuration
WARNING! With RS485 pay attention to standard polarization. Connect RS485+ to pin no. 3
and RS485- to pin no. 2 as shown in Figure 3 above.
