Wiring the switchboard's 24-hour input
The 24-hour input must be con
fi
gured as single balance with a resistance of 1,8 K
Ω
. Refer to the relevant paragraph for information about correct
connection of the tamper lines.
PSTN telephone dialler
To connect the telephone dialler to the telephone network correctly, you must
fi
rst locate the point at which the line enters the house. The dialler
must be connected as the
fi
rst device, as viewed from the incoming telephone line.
To ensure that the line protection devices work correctly, it is imperative to earth the corresponding terminal of M1. For this purpose, the housing
is predisposed with a length of insulated copper braid, in yellow/green, to facilitate connection of the earth terminal of switchboard terminal block
M1 to the earth terminal of the power supply unit.
Main control and display components
LCD keypad (art. 30006002)
Using the LCD keypad, authorised users can activate and deactivate the system, check and manage system status as a whole, and check the
events log records.
Using the keypad, it is also possible quickly to modify the system settings and the options of each individual output.
Operations are performed by means of a combination of numerical keys and function keys, whereas feedback is both visual (alphanumeric
display and LEDs) and aural (buzzer.)
The LCD keypad is equipped with 2 freely con
fi
gurable alarm inputs.
Main features:
• Backlit 2 x 16 character LCD display
• initial software addressing, from built-in keypad
• Four LEDs for immediate indication of power ON, battery alarm, generic error and alarm in progress
• Backlit keypad with ten number keys and eleven function keys.
•
Two universal inputs, con
fi
gurable as NC, NO, single, double and triple balance, double zone and double zone with termination, with possibility
of direct connection of roller shutter contacts (switch alarm).
• on-board 485 bus end-of-line resistor, which can be activated by DIP switch
• ant-tamper and anti-tear tamper
Meaning of LEDs
The keypad features 4 LEDs; their meaning is as follows, working from top to bottom:
1. Green, Mains Power, steadily lit when the presence of mains power is detected
2. Yellow, Battery, if lit indicates a battery anomaly (disconnected, faulty or with voltage of less than approximately 11.8V)
3. Yellow, Anomaly, if lit indicates that the system is affected by at least one anomaly.
4. Red, Alarm, if
fl
ashing indicates the presence of an alarm memory state.
