Radio Control PanelCU-IQ
CU-IQ MANUAL
1. DESCRIPTION
The small control panel CU-IQ is one component of the new ICAS IQ wireless system. IQ
System is an intelligent radio system, which works at
8 8 MHz frequency band. The IQ System is created
by various kind of IQ components, which provides to
the customer complete and very flexible RF fire alarm
system. All components of the IQ system use a special
RF communication protocol. This protocol handles
building small or large size, smart installations,
depending directly on the user requirements. The
smart installation consist of systems, which control
their local loops of IQ components (nodes). The
systems are connected to the RF (radio frequency) loop, which is identified by the individual Loop
ID number. Each installation depending on complexity can contain from 1 to 8 systems, where
systems are also described with individual System ID. RF communication principle in systems is
based on ”STAR” topology and RF communication principle among systems (all systems in
installation has information about other systems) is based on “P2P” topology. This kind of
configuration and system description allows making very flexible small or large installations
according to customer demands. Big advantage of the system is that most of IQ components are
battery operated with 10 years lifetime. This allows the customer to install all components without
special power supply wiring projection.
Control panel CU-IQ serves as controller of the system. It is equipped with indication of the
local loop events and also with the remote events which could occur in other systems local loop.
CU-IQ tests also communication in the system, also tests communication between other systems
in installation and communication with other system part at RS485 line. The control panel includes
power line and external power supply indication and is equipped with two relay outputs and siren.
The panel functions could be controlled by three push buttons.
The typical application is CU-IQ wireless connection with up to 32 optical detectors CHOR-IQ
(one system with one Loop ID and System ID). The larger application is the configuration from 2 to
8 CU-IQ in installation (up to 8 systems with one Loop ID and different System ID). All CU-IQ
are connected together into loop with identical Loop ID and each CU-IQ has specified its own
System ID. Each system can handle up to 32 assigned CHOR-IQ detectors.
CU-IQ is also equipped with RS485 transceiver, which is used for connection up to 14 RS485
communication modules CU-M.485 or for connection up to 13 CU-IQ. It could be useful for
installations, where could be problem with radio frequency loss.
