"R2" radio receivers
Warnings
• Before you start installing the receiver, make sure it is suitable for its intended
purpose; pay special attention for the data provided in the "Technical
Characteristics" chapter. MHOUSE disclaims responsibility for any damage
resulting from improper use of the product; the only use authorized by the man-
ufacturer is the one described in this manual.
• Protect the receiver from water and other liquids and do not place it near heat
sources or expose it to open flames;if this should occur, stop using it immedi-
ately and call MHOUSE customer service;
• All the installation operations must be performed while the devices are discon-
nected from the power supply.
Description and Intended Use
The R2 receiver, used in combination with the TX4 transmitters, is suitable for the
remote control of electrical equipment such as gate control units and similar
automations; The receiver has two outputs with normally open (NO) relay contact.
When the transmitter sends a signal that is recognized as valid, the receiver caus-
es the activation of the corresponding output relay (the contact closes). The relay
will deactivate as soon as the transmitter stops sending the radio signal.
Installation
Receiver
The R2 receiver (Fig.1) enables universal use. The casing provides essential and
efficient protection to the circuit. It can be secured with the adhesive on the bot-
tom.
Selecting the power supply
The receiver's power supply is 24V (both direct and alternate current). However, R2
can also be connected to a 12V power source. To do this, just insert the jumper
shown in Fig.2
Table 1
Jumper not inserted 24 V ac/dc
Jumper inserted 12 V ac/dc
Electrical connections
The receiver is connected through colour-coded conductors (Fig.3):

Terminals 1, 2 AERIAL input
Aerial
The R2 receiver is equipped with an internal aerial (the length of wire just con-
nected to terminal 2). However, in order to obtain a better performance it can be
connected to an external aerial (for example, the one found on the FL1 flashing
light by Mhouse).
The aerial should be installed as high as possible, never under but eventually over
metal or concrete structures which could blind it. Use coaxial cable (RG58, for
example) with a maximum length of 5m. Connect the centre part of the cable to
terminal 2, and the braid to terminal 1.
Memorizing the transmitter
To enable the transmitter to command a receiver, a memorization procedure must
be carried out.
Two methods can be followed to memorize the new transmitter:
• Mode 1: in this "mode" the radio transmitter is used to its fullest extent, i.e. all
the buttons carry out the command associated to the corresponding output.
In "mode 1", the commands associated to the 4 buttons (Fig. 4) are the following:

Transmitter Radio receiver
Button T1 Activation of output relay No. 1
Button T2 Activation of output relay No. 2
Button T3 Not used
Button T4 Not used
• Mode 2: in this "mode", each transmitter button can be associated to one of
the two receiver outputs. If this mode is used properly, it will be possible to com-
Technical characteristics
R2 is produced by NICE S.p.a. (TV) I, MHOUSE S.r.l. is an affiliate of the Nice
S.p.a. group.
Nice S.p.a., in order to improve its products, reserves the right to modify their tech-
nical characteristics at any time without prior notice. In any case, the manufactur-
er guarantees their functionality and fitness for the intended purposes.
Note: all the technical characteristics refer to a temperature of 20°C.
R2 Receivers
Type: Radio receiver for control of automatic gates, garage doors and similar
automations
Technology adopted: Reception and decoding of the radio signals emitted by
the transmitters. Activation of the output relays only in case of correspondence
with a previously memorized code, correctly synchronized with the variability
sequence.
Possibility of remote control: With TX4 transmitter
Coding: 64 bit rolling code (18 billion billion combinations)
TX4 transmitter memorization capacity: Up to 256, if memorized in mode 1
Reception frequency: 433.92 Mhz
Voltage limits: 18÷35Vdc, 15÷28Vac
Voltage limits: 10÷18Vdc, 9÷15 Vac

Button T1 activates output No. 1 on receiver A; button T2 activates output No.
1 on reciver B; button T3 activates output No. 2 on reciver A; button T4 acti-
vates output No. 1 on reciver C.
Each transmitter is, of course, a separate unit, and while some are memorized
in "mode 1" others can be memorized in "mode 2" on the same receiver.
Warning: since the memorization procedures are timed (max. 10 seconds for each
stage), you need to read the instructions in the following paragraph before you pro-
ceed to carry them out.
Memorizing the transmitter in "mode 1"
1. Press button P1 [H] Fig.5 on the receiver for at least 3s; when the P1 LED [I]
lights up, release the button.
2. Within 10s, press any button on the transmitter to be memorized for at least 2s.
If the memorization procedure is successful, the P1 LED will flash 3 times.
3. If there are other remote controls to be memorized, repeat step 2 within the next
10s, otherwise the memorization stage will terminate automatically.
Memorizing the transmitter in "mode 2"
With the memorization of the transmitter in "mode 2", each button can be associ-
ated to any of the two radio receiver outputs (see table 4).
In "mode 2", each button requires a separate memorization stage.
1. Press button P1 [H] Fig.5 on the receiver as many times as the number corre-
sponding to the desired command, according to the following table (e.g. 2 times
for "Activation of output N. 2"):
Table 4
Button P1 Radio receiver
1 time Activation of output No. 1
2 times Activation of output No. 2
3 times Not used
4 times Not used
2. Make sure that the P1 LED [I] Fig.5 flashes as many times as the number of the
selected output.
3. Within 10 s, press the desired button on the transmitter to be memorized, and
hold it down for at least 2s. If the memorization procedure is successful, the P1
LED will flash 3 times.
4. If there are other remote controls to be memorized for the same type of com-
mand, repeat step 3 within the next 10s, otherwise the memorization stage will
terminate automatically.
Remote memorisation
It is possible to memorize a new transmitter without directly operating the buttons
on the radio receiver, provided you have an "OLD" pre-memorized operational
transmitter.
The NEW transmitter to be memorized will inherit the characteristics of the OLD
one, i.e. if the OLD transmitter was memorized in "mode 1", the NEW one will also
be memorized in "mode 1". In this case, during the memorization stage you can
press any key on the two transmitters.
If, on the other hand, the OLD transmitter was memorized in "mode 2" you must
press the button on the OLD transmitter which corresponds to the desired com-
mand, and the button on the NEW transmitter to which you wish to associate that
command.
Holding the two transmitters, position yourself near the control unit or receiver and
perform the following operations:
1. Press the button on the NEW transmitter and hold it down for at least 5s, then
release it.
2. Press the button on the OLD transmitter 3 times slowly.
3. Press the button on the NEW transmitter once slowly.
At this point the NEW transmitter will be recognized by the control unit or receiver
and will assume the characteristics of the OLD one.
If there are other transmitters to be memorized, repeat all the steps above for each
new transmitter.
