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 SRM-22 controller is designed for installa-
tion in switch cabinets on TH35 bar. Receiver’s
body takes up two modules. It is required to
connect an antenna for correct operation. If you
need to install the antenna outside 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
over current 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 TH bar in the switch-
gear.
5. Activate the supply circuit and check for cor-
rect operation.
1. The controller works with 230 VAC single-phase motors with limit switches or overload switches. Up
to two motors can be connected to the controller. Do not connect more than one motor to a single
output on the SRM-22. You must observe maximum rated output load — 350 W (2 A) for loads in class
AC3.
2. It is not recommended to install drivers in metal switch gears due to the fact that metallic material has
very strong dampening features of radio waves which could result in a significant reduction of range.
3. It is recommended that the shutter connected to the specific output of the controller during installation
and programming be in the extreme position (fully opened or closed). If not, after programming the
remote or pairing a control unit with the controller, it is necessary to make several shutter movements
to place it in the extreme position (top or down).
4. You can use inputs of SRM-22 controller to connect spring-action shutter switch for wired control.
By default, the controller works with double spring-action shutter switches. In order to connect single
switches, connect inputs ▼ and ▲ assigned to the shutter or using mobile application set “Single
shutter switch” (then you can connect the switch to input ▼ or ▲ to the shutter).
CAUTION: If you connect input terminals ▼, ▲ for the shutter to connect a single switch, you
must reapply power supply to the SRM-22.
By connecting the input terminals of one shutter, the inputs of the second shutter will automatically start
operating as inputs for working with single switches (after physically connecting the inputs, you cannot
have one shutter controlled with single shutter switch and the second with double switch). Such switch
arrangement is possible only when inputs are configured from mobile app working with EXTA LIFE
controller.
5. During the installation make sure that the receiver is not exposed to direct water impact or operation
in increased humidity environment. The temperature at the installation site should be from -10 to
+55°C.
6. The SRM-22 controller is designed for indoor installation. In case of outdoor installation, place the
receiver in an additional sealing box and efficiently seal against water penetration.
7. After installing the SRM-22 controller, check it for proper operation. When using EXTA LIFE system
transmitters for control, you must first program them with a receiver (see Programming the transmit-
ters). To work with the controller, the receiver must be properly paired with the controller (see Re-
ceiver registration in the EXTA LIFE system). Local inputs in default operating mode are immediately
ready to use.
REMOTE SOFTWARE UPDATE
The SRM-22 receiver has a built-in bootloader for remote updating of software from EXTA LIFE app.
Updating is possible only for receivers paired with controller and can be carried out by the user with
administrator’s rights. To perform update, you must download the latest version of software from ex-
talife.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 SRM-22 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 control-
ler. During the update, the receiver and controller are switched to service frequency and cannot be
controlled. After a 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 the green STATUS
LED blinking continuously every
1 s). Then, selecting “Version in-
formation” in the app for the re-
ceiver, then it will be possible to
repeat the update process.
CAUTION: Do not delete the
receiver with an update error
from the controller’s resources.
