The control panel gets its power from a switching power supply, which can give a continued 3A, and is
supplied with a connection for a back up battery (7 Ah/17 Ah).
The control panel checks itself and its components constantly. With the AlphaVision NG control panel, you
can speak of a true integration with all connected components. This means that all available information is
collected, identified, processed and made visible.
EOL inputs
The AlphaVision NG control panel has 8 inputs for connection of 8 zones. By using expansion modules,
such as I/O modules, Input + 8 OC module or the wireless interface, you can expand the number of zones to
a maximum of 96 zones. Each expansion module has 8 inputs for connecting 8 extra zones. (In case of the
wireless interface you have to learn the wireless detector’s ID number into the memory of the wireless
interface).
Usually the most zones will be programmed as Normally Closed with End of Line resistor. It is also possible
to use Normally Open zones, even when using the End of Line principle. This can be programmed for each
zone separately. See also screen 1 of the programming at page 34).
Standard zones are connected using the End of Line principal (EOL). By using
the end of line resistors, the cable between the control panel and the detector is
constantly checked. For this, a 1k8 resistor is placed at the end of the cable, so in
the detector’s or magnetic contact’s casing, in series with the input. Over the
detector’s alarm contact a 10k resistor is placed. Usually speaking NO resistor is
placed over the tamper contact. You can however place a 39k resistor over this
contact.

For the most Visonic detectors, EOL plug-on boards are available. These
PCB’s are placed under the detector’s clamps. The three EOL resistors,
including the optional 39k resistor, are implemented on this PCB. If you
do not use the plug-on boards, you do not have to use the 39k resistor.
The EOL plug-on board looks as follows:
