Vigilon fire system
Programmable input/output
All S-Quad devices can be con
fi
gured as either monitored input or unmonitored output.
The factory setting of the programmable input / output is unmonitored output, to drive
an external repeat LED without a series resistor. There is a maximum cable length limit
of 15 metres from the S-Quad base to the external I/O Unit.

Input
Beam Transmitter base
The input can accept signals such as
fi
re, non
fi
re or fault, these are con
fi
gured during
commissioning. As a
fi
re input it is possible to connect a conventional Manual Call
Point (non UK application only) with a series resistor of value 470 Ohms coupled with
an end-of-line 10Kohms resistor. In this case the
fi
re input is fully monitored for open or
short circuit faults.
The input can be setup as a non-
fi
re or fault input using a similar arrangement with
series and parallel resistors as shown. It is possible for such an input to trigger a
command that is con
fi
gured to action an output elsewhere in the system to control
plant equipment such as ventilation system in a building.
