NEXA MCMR-2000 Built-in Receiver On/Off 1 Channel
TECHNICAL DATA
A declaration of conformity is available online at www.nexa.se
Built-in receiver for wireless control of lights, etc. The receiver needs both a phase and a neutral connection. The receiver is fully compatible with other System Nexa products.
SAFETY
Read all the instructions carefully first. Call in a professional if
necessary. Nexa cannot be held liable if the product is used for any purpose
other than that for which it was designed, or if the associated instructions
are not followed.
Never connect lights or any equipment that exceeds the maximum stated load of
the receiver, as this can result in faults, short circuit or fire. Do not
attempt to repair the product.
The product contains no serviceable parts.
INSTALLATION
Make sure that the wires are free from voltage by disconnecting the current in
the electricity panel.
Connect the phase (Live) to L, Neutral to N and the outgoing power line (load)
to L(arrow), see the circuit diagram.
PROGRAMMING
In order to operate the MCMR-2000 with a System Nexa remote control (or other unit), the transmitter and receiver must be connected as follows:
- Connect voltage to the MCMR-2000
- Briefly press the “programming” button, the LED indicator will start to flash slowly.
- Press the “ON” button for the selected channel on a System Nexa remote control within 12 seconds.
To program other System Nexa units (Motion detector, Magnetic switch, Bridge, etc.) see the instructions for use for the respective products.
CONFIRMATION OF PROGRAMMING
The relay in the MCMR-2000 clicks 4 times and any lights connected flash 2
times.
DELETE MEMORY SLOT
- Connect voltage to the MCMR-2000
- Briefly press the “programming” button, the LED indicator will start to flash slowly.
- Press the “OFF” button for the selected channel to be deleted from a System Nexa remote control within 12 seconds.
To delete programming from other System Nexa units (Motion detector, Magnetic switch, Bridge, etc.) see the instructions for use for the respective product.
CONFIRMATION OF DELETION
The relay in the MCMR-2000 clicks 4 times and any lights connected flash 2
times.
DELETION OF ALL MEMORY SLOTS
- Connect voltage to the MCMR-2000
- Press the programming button and hold it down for 6 seconds. The LED indicator starts to flash quickly.
- Release the programming button and then press it briefly once more.
CONFIRMATION OF DELETION OF ALL MEMORY SLOTS
The relay in the MCMR-2000 clicks 4 times and any lights connected flash 2
times.
MEMORY
The MCMR-2000 has 32 memory slots and can be controlled from up to 32
different units (remote controls, motion detectors, magnetic switches, Bridge,
etc.). If all memory slots are filled, the oldest slot will be deleted when a
new channel is programmed.
CONTROL
The receiver can be controlled in several ways.
- With a programmed System Nexa Remote Control
- With other programmed System Nexa transmitters
- With a Nexa Smart Hub
- With Nexa Bridge
SAFETY AND INFORMATION
Range indoors: up to 30 m (optimal conditions). The range is heavily
dependent on local conditions – such as if there are any metals nearby. For
example, the heavy metal coating in low-emission energy glass has a negative
impact on the range of the radio signals. There may be limitations on the use
of the unit outside the EU. If appropriate, check that the unit complies with
the local regulations.
Max. load: Never connect lights or equipment that exceeds the maximum
load of the receiver. This can result in faults, short circuit or fire.
Life support equipment: Never use Nexa products for life support
equipment or other devices where faults or disruptions can have life-
threatening consequences.
Disruptions: All wireless units can be affected by disruptions that may
have an impact on performance and range. The minimum distance between two
receivers should therefore be at least 50 cm.
Repairs: Do not attempt to repair the product. It does not contain any
serviceable parts.
Waterproofing: The product is not waterproof. Make sure that it is always
dry. Moisture will corrode the electronic components inside and may result in
short circuit, faults and risk of electric shock.
Cleaning: Clean the product with a dry cloth. Do not use chemicals,
solvents or potent cleaning agents.
Environment: Do not expose the product to extreme heat or cold, as this
may damage the electronic circuits or shorten their service life.
