2. SYSTEM STRUCTURE
ENIGMA II monitoring receiver provides complex and reliable solution to build up a
modern monitoring station. The device can receive signals from alarm control panels
through IP network, telephone line and radio channel. Due to the universal operation,
the device can receive all standard (and most of the non-standard) signals from alarm
control panels and communicators. With combination of an appropriate PC-based
monitoring software it guarantees not only reliable signal transmission, but also easy to
use operator interface. The system consists of the following devices:
2.1 CPM card
Central processing card (CPM) which controls the operation of the receiver. CPM
contains two serial ports (respectively 2 high speed USB ports), one Ethernet port and
one parallel printer port. CPM card can store up to 2000 events in its non-volatile
memory. If the connection fails with monitoring computer, the receiver stores events in
its own memory, and all events will be sent automatically when the connection is
restored. CPM controls the graphical LCD display as well, where received events can
be seen and basic settings can be done.
2.2 LC telephone line card (optional)
Receiver has 8 slots to connect LC telephone line cards. LC line cards can monitor one
telephone line. Each telephone line card have memory to store up to 500 events or
caller ID. Caller ID function is built in, the caller telephone number is stored and can be
transmitted to monitoring computer. Line cards support two-way audio communication
also. Line cards are continuously monitored by CPM. All line card troubles are displayed
immediately at LCD display, and transmitted to monitoring computer. The line card
monitors the connection with CPM as well, if it detects trouble automatically switches to
standalone operation mode. In this case it continues event receiving, but stores them in
its own memory. All received events will be sent automatically to CPM when the
connection is restored.
