Communicator connector
– allows the connection of an
optional communicator to the main board.
Internal wiring connector
– connects the internal wiring in the
control panel housing.
Terminals:
AC 20V
the transformer output is connected here.
01, GND, 02
are hard-wired inputs for the control panel
.
•
The reactions to triggering these inputs are determined by the
settings of addresses 01 and 02. The factory-set natural
reaction for these hard-wired inputs is a delayed alarm in
section C.
•
Terminals 01 and 02 use resistors in connected double
balanced loops to sense loop stand-by, activation or
tampering as follows:
o
Connected to GND via a
1 k
Ω
resistor = untriggered
input
o
Connected to GND via
2 to 6 k
Ω
= triggered input
,
o
Connected to GND via
less then 700
Ω
or more then 6 k
Ω
=
tamper signal
o
Stand-by (untriggered) input zone must have 1
k
Ω
o
Up to five normally-closed door/window contacts can be
connected in series to enable one hard-wired input to be
used for multiple contacts with each contact having a 1k
Ω
resistor in parallel (see the diagram below).
o
Multiple normally-closed tamper contacts should be
connected in series without any parallel resistors. The
number of tamper contacts is unlimited and can be
combined with trigger contacts having parallel resistors (see
the diagram below).
o
For wiring examples, see the below diagram.
o
If you
enroll a wireless device to address 01 or 02,
the
corresponding input terminal
will be disabled
.
o
If you do not use an input terminal and you do not enroll a
wireless device to its address, then the terminal must be
connected to the
GND
terminal via a 1
k
Ω
resistor.
NC
–
normally closed contact for the external warning relay.
NO
-
normally open contact for the external warning relay.
EWC
– common contact for the external warning relay
max.
relay contact rating: 1A/60V.
The control panel also transmits
the external warning relay signal via radio for wireless sirens.
IW
– internal warning (siren) output. This output is grounded
during an internal alarm. A standard siren can be wired between
terU and IW (
max. 0.5A
).
The IW output status is also
transmitted by radio for the IW siren.
The main difference between internal and external warning is during
the entrance delay period. If any instant detectors are triggered during
the entrance delay period, e.g. a child running straight to the living
room, only an internal warning will be triggered and an external
warning will only follow if the entrance delay has been exceeded.
PGX, PGY
– are a pair of terminals providing programmable
outputs. If an output is activated it switches to GND with a
maximum load of 0.1A/12V. The factory-default setting of PGX is
the function ON/OFF which can be operated from the keypad by
the instruction
∗
81 /
∗
80 or using keys
). The factory-default
function of PGY is that it will be activated if any section of the
system is set. The status of PG outputs is also transmitted by
radio for AC and UC output modules.
GND
– common ground connection
A,B
– digital bus data
+U
– back-up power supply (10 to 14V), 1A fuse. Max.
continuous load 0.4 A (max. intermittent load 1 A, for 15
minutes, once an hour). If the 1A fuse is blown, the control panel
will indicate power supply fault.

control and programming
keypad JA-80E
modular connection
cable
The control panel can be operated and programmed by JA-
80F wireless keypads and/or a JA-80E hard-wired keypad. A
hard-wired keypad can be connected to the control panel either
by flat telephone cable (max. length 10 metres) using RJ
connectors, or via twisted-pair cable (max. length 100 metres)
connected to the digital bus terminals (GND, A, B, +U).
We recommend only having a single JA-80E hard-wired
keypad in the system.
6. Back-up battery
It is possible to use a Jablotron-brand 12V back-up battery in
the control panel with capacities of 1.3Ah or 2.6no Ah. The
capacity to use depends on the total power consumption of the
system and the desired back-up period.
Euro-standard EN 50131-1 specifies a 12 hour minimum back-
up time for grade 2 systems. The standby consumption of all
system devices is shown in table 1.
Table 1- standby consumption of system devices
•
With a
1.3Ah
back-up battery 12 hours of back-up time can be realised if
current consumption does not exceed
85mA
. With
2.2Ah
batteries
150mA
should not be exceeded to achieve the same. This only takes
80% of the battery capacity into account as 20% has to be reserved for
battery aging effects.
•
The average
back-up battery lifetime
is
up to 5 years
after which it must
be replaced. The back-up battery is automatically charged and its
condition is monitored by the system. If the system is being run on only
the back-up battery a technical alarm occurs when the battery is
nearly discharged. If the voltage gets too low the battery will be
Device mA
