n BPI bus wiring
No BPI device can be more than 500 meters (in wire length) from the Panel. The overall wire length for each
branch of the BPI bus can be no more than 1,000 meters.
If the voltage across terminals [+] and [ ] is less than 10 V (the voltage required by the BPI devices) it is possible to:
Ø
increase the wire section that supplies the device (the wires that connect terminals [+] and [ ] of the Panel to ter-
minals [+] and [ ] of the device);
Ø
connect a power station to boost the voltage;
Ø
connect a power station to supply the devices connected to the BPI devices.
Alarm sensor connection
The Panel provides 8 zones on the Main board; 4 Zones per Input Expander; 1 Zone per keypad for the connec-
tion of alarm sensors.
Academy40
and
Academy40/S
can manage up to 40 zones
The input zone terminals are marked [L1], [L2], etc.
The following terminals supply the sensors:
----

(positive) and
[ ]
(negative) on
Academy40
and
Academy40/S
----
[+F]
(positive) and
[ ]
(negative) on
Input Expanders
----
[+]
(positive) and
[ ]
(negative) on
Keypads
Several sensors can be connected to each zone, although, connection of one sensor is strongly advised, as this
will allow identification of the sensor in alarm status.
It is possible to connect sensors with normally closed contacts and normally open contacts. All input zones are
programmable as Normally Closed, Normally Open, Balanced or Double balanced.
Use the 10 K resistors (provided) for Balanced or Double Balanced Zones.
The Balance resistors are not required for Normally Closed or Normally Open zones.
