Description of the terminal boards
L1 ...L16
= Input terminals of the lines with configuration which can be programmed
as double balanced or NC.
The events generated by the anomaly of each input can be programmed.
The inputs are 80 in total, the transponders of the CP80 CP90 CP100 series of control
units must be used from input 17 up to the last one to be managed.
AUX 485
= RS485 terminal board for connection to a network of El.Mo control units
managed by PC or in large centralisation systems.
B - A
= Connection terminals of the RS485 serial port for a line of compatible
transponders with CP80, CP90, CP100 series of control units. The serial line makes it
possible to expand the control unit up to a maximum of 80 inputs.
It is necessary to connect the cable of the serial line with four wires, taking the mains
supply from the right-hand terminal board; in the event of connection with three wires
only the terminal B- A and the negative of the right-hand terminal board will be used.
With the serial line exiting from the terminal board, it is necessary to connect a 680
Ohm end resistor between the terminals A and B while the second one must be
connected to the same terminals of the last transponder used.
+ 12V - QT
= RS485 terminals for connection of the external control mechanisms of
the control unit identificable in NADIR, AURORA, ZENITH models.
The mains supply terminals can also be used for supplying power to the transponder
devices of the serial line which may be connected in order to expand the system.
TAMPER RELAY C - NC - NA
= Output terminals of the TAMPER alarm relay
corresponding to contacts free from potential. Contact capacity 800 mA @24V.
To use only for connection to circuit working with SELV voltage , for example to
drive optical-acoustic warning devices or inputs for radio links, etc.
ALARM RELAY C - NC - NA
= Output terminals of the general alarm relay
corresponding to contacts free from potential. Contact capacity 5A @24V. To use only
for connection to circuit working with SELV voltage , for example to drive optical-
acoustic warning devices or inputs for radio links, etc.
SENS. POWER +12V-
= Output terminals for powering sensors or other devices,
the voltage is always present and the output is protected by the F3 F5A fuse.
+RIF SIR
= Output terminal of the control voltage for self-powered sirens. The voltage
is present when the control unit is in stand-by; during general alarm status, the voltage
drops for the duration of the timing set when programming the control unit.
Use two wires for connection, one linked to the +RIF SIR and the other linked to the
left-hand negative terminal.
TAMPER
= Connection terminal of the system TAMPER input to which the various
protection microswitches for the system’s housing or other connected devices must
link. The WHITE TAMPER CONNECTOR is positioned in series to this input; this
connector constitutes the point of connection of the control unit protection circuit made
off the microswitch protecting against housing opening placed in contact with the
screws fastening the door. It is possible to connect the base protection kit in series to
the latter, as shown in the diagram featured in this manual.
EARTH FASTON
= Male connector for the earth connection of the control unit and
housing protections; the connection is made beforehand by the manufacturer.
LA, LB, LA’, LB’
= Connection terminals of the telephone dialler built into the master
board. Follow the connection diagram illustrated in this manual.The earth terminal is
placed between the telephone line input terminals (LA and LB) and the output
terminals (LA’ and LB’). To the earth terminal connects the standard protections of the
telephone interface. Make the connection to an effecient earth.
