Product Description - Nice SMX2 Instrucciones Y Advertencias Para El Instalador

Product description

SMX2 and SMX2R are dual-channel radio receivers that are
designed for general use and differentiate themselves for their com-
patibility with transmitters.
SMX2 SMILO
SMX2R FLOR and VERY VR
Installation
Power input selectio
Insert or remove a jumper from its seat to select power input:
Jumper not inserted
Jumper inserted
Electrical connections
The receivers are provided with power and 2 outputs on the output cabling:
Red / Black
Red= Positive, Black= Negative. Position is not important if alternating current is selected
White / White
Free contact of a normally open relay
Purple / Purple
Free contact of a normally open relay
Terminals 1, 2
Aerial signal input (terminal 1 braid, terminal 2 core)
Contact in receiver output
The outputs are commanded by a relay with a normally open "NO" contact. If a normally closed "NC" type of contact is needed: disconnect
the power supply from the receiver, open the box, first from below as shown in Fig.5a and then from above as shown in Fig.5b, carefully
remove the board and work on the welding side of the receiver as follows:
1. Cut the part of the track at point X.
N.B.: this operation can be performed both for relay N°1 and for relay N°2.
2. Join the pads in point Y with a spot of solder.

Installing the aerial
The receiver requires an ABF or ABFKIT type aerial to work properly;
without an aerial the range is limited to just a few metres. The aerial must
be installed as high as possible; if there are metal or reinforced concrete
structures nearby you can install the aerial on top. If the cable supplied
with the aerial is too short, use a coaxial cable with 50-Ohm impedance
(e.g. low dispersion RG58), the cable must be no longer than 10 m.

The peculiarity of compatible transmitters is that the identification
code is different for each transmitter. Therefore, in order to recognise
a determined transmitter, the recognition code must be memorised.
This operation must be repeated for each transmitter to be used.
The receivers are provided with power and 2 outputs on the output
cabling:

NO
If the aerial is installed in a place that is not connected to earth
(masonry structures), the braid's terminal can be earthed to provide
a larger range of action. The earth point must, of course, be local
and of good quality. If an ABF or ABFKIT aerial cannot be installed,
you can get quite good results using the length of wire supplied with
the receiver as the aerial, laying it flat.
