Connect the device to single-
phase mains, according to appli-
cable standards. The connection
method is shown in this manual.
The activities related to the instal-
lation, connection and adjustment
should be performed by qualified
electricians, familiar with the user manual and func-
tions of the device. Removing the housing leads to
the loss of guarantee and creates the risk of electric
shock. Before starting installation, ensure connec-
tion lines are not supplied with voltage. For instal-
lation, use a Philips screwdriver with a diameter of
up to 3.5 mm. The correct operation of the device
can be affected by transport, storage and opera-
tion. Installing the device is not recommended in
the following cases: no components, damage to the
equipment or deformities. In the event of malfunc-
tioning, contact the manufacturer.

INSTALLATION
NOTES
The ROM-24 receiver is designed for instal-
lation in switch cabinets on a TH35 (DIN) bar.
The receiver’s body takes up two modules. It
is required to connect an antenna for correct
operation. If you need to install the antenna out-
side the switch cabinet (applies mainly to metal
switchboards), you can use external antenna
ANT-01 with a 3 m cable. The antenna with an
SMA type connector.
1. Disconnect the supply circuit with a fuse, an
overcurrent circuit breaker or an isolator con-
nected to the corresponding circuit.
2. Check the voltage-free status of the power
cords with a suitable instrument.
3. Connect the wires to the terminals according
to the connection diagram.
4. Install the device on a TH35 (DIN) bar in the
switchgear.
5. Turn on the supply circuit and check for prop-
er operation (when an output is triggered, the
red LED assigned to it should light up).
1. Observe the maximum output current-carrying capacity value:
● incandescent and halogen light bulbs: 750 W / per channel
● compact fluorescent lamps (CFL): 250 W / per channel
● LED lamps: 60 W / per channel
2. During the installation make sure that the receiver is not exposed to direct water impact or opera-
tion in increased humidity environment. The temperature at the installation site should be from -10
to +55°C.
3. The ROM-24 transmitter is designed for indoor installation. If installed outdoors, the receiver must
be placed in additional pressure-tight housing and protected against the ingress of water particu-
larly from the terminals side.
4. The receiver has a detachable antenna. You can also connect an external antenna ANT-01 and
install it outside the switchboard.
5. Installation connectors for wired control can be connected to inputs from IN1 to IN4 of the ROM-24
receiver. By default these inputs are designed for work with monostable connectors, i.e. buttons
working in bistable mode. This means that each consecutive pulse supplied to the input changes
the status of the specific output to opposite one. By default, input IN1 controls channel 1 (CH1),
input IN2 — channel 2 (CH2), input IN3 — channel 3 (CH3) and input IN4 — channel 4 (CH4).
CAUTION: Functionality of inputs (connector type, operating mode) may be changed only
using EXTA LIFE mobile app working with EFC-01 controller — see Input functionality.
6. After installing the receiver, check it for proper operation. When using EXTA LIFE system transmit-
ters for control, you must first program them with a receiver (see Programming the transmitters).
To work with the controller, the receiver must be properly paired with the controller (see Receiver
registration in the EXTA LIFE system).
REMOTE SOFTWARE UPDATE
The ROM-24 receiver has a built-in bootloader for remote updating of software from the EXTA LIFE
app. Updating is possible only for receivers paired with a controller and can be carried out by a user
with administrator’s rights. To perform an update, you must download the latest version of software
from extalife.pl and move it to an SD card in the controller; read the manual “Updating software in
EXTA LIFE receivers”. The manual can be downloaded from extalife.pl.
The current software version of the ROM-24 receiver is shown on “Version information” tab. After
pressing the “Update” button, you are sending information to the controller which switches the receiver
into software update mode. The latest version of software is sent to the receiver from the controller.
During the update, the receiver and controller are switched to service frequency and cannot be con-
trolled. After successful update, the applicable information about is sent from receiver to the controller
and signalled in mobile app.
If the update procedure fails for some reason, then it will be shown as a receiver with update error
on the controller. The receiver loses its original functionality (which is signalled by green STATUS
LED blinking continuously every 1 s). Then, you can go to “Version information” screen and restart
the update process by pressing “Update” button. Pressing this button will restart the software update
process.
CAUTION: Do not delete the receiver with an update error from the controller’s resources.
