Setting the BPI Level
The BPI Level determines the
maximum voltage the BPI bus can carry. Some BPI de-
vices have 5 V and 12 V options.
+
This Control Panel operates at 12 V, therefore, all
the peripheral devices must be set at
12 V.
Refer to the BPI device instructions for the BPI Level
setup.
n
BPI bus Wiring Limitations
Due to Voltage drops and stray capacitance caused by
the Control Panel BPI bus connections, the following
wiring limitations must be respected:
Ø
the maximum wire length between the
Control
Panel
and the BPI peripheral must not exceed
500
metres;
Ø
the overall wire length of the
Control Panel
BPI bus
must not exceed
1000
metres.
In order to allow the BPI peripherals to operate properly,
11.5 V
or more must be present across terminals [+]
and [–]. If a lower voltage is present, it can be boosted
by:
Ø
increasing the wire size that supplies the Control
Panel BPI device (the wires that connect [+] and [–]
of the Control Panel to terminals [+] and [–] of the BPI
device);
Ø
connecting some of the BPI peripherals downstream
of a Power Station (these devices will be powered by
the Power Station, therefore, will not load the Control
Panel BPI bus);
Ø
using a Power Station to provide the voltage for the
BPI peripheral load.
+
The cable length downstream of a Power station
should not to be included the overall wire length for
the Control Panel BPI bus.
Connecting Detectors
You can connect the detectors to:
Ø
terminals L1, L2, L3 and L4 of the Control Panel;
Ø
terminals T1, T2, T3 and T4 of the Control Panel, if
programmed as Input Lines (Zones);
Ø
terminals T1, T2 and T3 of the
T-Line
and
PREMIUM
keypads, depending on the programmed operating
mode (refer to the keypad instructions for more infor-
mation);
3
Grade 3 detectors CANNOT be connected to the
Keypads.
Ø
terminals T1, T2, T3, T4, T5 and T6 of the Input/Out-
put Expander M-IN/OUT, depending on the pro-
grammed operating mode (refer to the M-IN/OUT’s
instructions for more information).
The following terminals can be used for the power sup-
ply to the detectors.
Ø
[+F] and [
M
] (negative) for each pair of Input Lines
(Zones) on the
Control Panel
: 13.8 V positive is
present on [+F] terminals — protected by resettable
fuse (1.5 A).
Ø
[+F] and [
M
] (negative) for each pair of Input Lines
(Zones) on the
M-IN/OUT
Input/Output Expander:
13.8 V positive is present on [+F] terminals — pro-
tected by resettable fuse (0.4 A).
Ø
[+F] and [–] (negative) for three Input Lines (Zones)
on the
T-Line
and
PREMIUM
Keypad: 13.8 V posi-
tive is present on [+F] terminal — protected by
resettable fuse (0.4 A).
Each zone can support several detectors. However, if
more than one detector is connected, the Control Panel
will be unable to identify the detector in the event of an
Alarm.
The Control Panel can detect Alarm, Tamper and
Short-circuit on hardwired zones:
Ø
Zone Alarm will be signalled by an
Alarm on zone
event;
Ø
Zone Tamper will be signalled by a
Tamper on zone
event;
Ø
Short-circuit will be signalled by a
Tamper on zone
event.
3
Grade 3 Control Panels and the Input/Output Ex-
pander are ALSO able to detect and report the
Grade 3 detector faults.
