2.3.2. LED Signalling of CUP+ and LCP+
Flashing yellow led on the CUP+ indicates the processor is running and all the internal
processes of the unit are operating properly.
Flashing green led on the LCP+ indicates the processor is running and all the internal
processes of the module are operating properly.
Flashing red LED on the LCP+ module indicates communication via the RS232 bus. It also
flashes during the query period when communicating with the CUP+ unit. After turning the power
supply on, both LEDs of the LCP+ module light up simultaneously for 2 seconds. This brief operation
mode is intended for service purposes.
2.4. LIP+ – Line Input PERIDECT+
The input module is used for connecting an external device
positioned on the detection perimeter.
The LIP+ module has two double-balanced inputs (the first
input is equipped with balancing resistors of 2 x 1.2 kΩ, the
second one is fitted with 2 x 3k3 resistors). They are connected
parallel to the detection line at any point of its length. The
identification of the LIP+ module is defined using its address.
In practice, the input can be used for devices such as a magnetic
contact at the gate used to indicate whenever it is opened. Other
examples include an IR gate or a microwave barrier above the
gate or in the perimeter area that cannot be protected by fence.
2.5. LPP+ – Line Protection PERIDECT+
LPP+ overvoltage protection looks like a standard detector and uses the same casing. It is
used to increase the resistance to electromagnetic field and surge peaks such as those caused by
lightning bolts. It contains
a set of elements that
limit the potential voltage
interference peak
between the conductors
of the bus.
