Test
Press the test button shortly (till red led TEST gets on) - the UWI-IQ gets into the test mode, red LED indicates Test and the message 'T' is sent to other
nodes.
As soon as the other UWI-IQ in the wireless link or other UWI-IQ and CHOR-IQ detectors into the wireless system receive this message they will get into
the test mode too.
The further short press of the test button will stop the Test mode and Reset message 'R' is sent to stop Test mode in remote nodes of system.
The test mode will stopped also when R message has been received or automatically after about 3 minutes.
Diagnostic mode - hardware tests.
Press the button as long till both red and yellow LEDs are lighting together.
The diagnostic mode is indicated by periodical flashes of red and yellow LEDs at the same time
Local alarm/fault will activated local Loop output and ALARM/FAULT relay regardless the configuration set in diagnostic mode.
Press the button shortly for diagnostic mode stop.
Power supply
The UWI-IQ unit is supposed to be powered through the POWER ter/- from an external power supply (in case of the UWI-IQ to UWI-IQ link it is
powered mostly from the control panel or IRS-3 which is the UWI-IQ connected to). If the UWI-IQ unit is used as a node of the system with uCU-IQ, the uPU
power supply can be used also for UWI-IQ energizing. The power supply is indicated by greed LED on the UWI-IQ panel
The power supply voltage loss will be indicated by switch off of the green LED on UWI-IQ panel and after communication test period expiration also as a
communication fault on uCU-IQ control panel.
Software description:
The UWI-IQ unit is controlled by ICAS software application which is installed into the ATTINY44A, this software has been designed in ATMEL assembler
language and cooperates with the second ICAS application software which is designed in C language and programmed into IQRF radio-module and on
background of this application is running the IQRF OS. The UWI-IQ takes advantage of use of the same application software of IQRF radio-module
The ATTINY software controls the timing of processes and switch between standby mode with very low current consumption and active mode which is
activated periodically by watchdog wake up technique.
Advanced Digital Signal-filtration (ADS)
The UWI-IQ software solution guarantees a correct signal handling and reduce nuisance of false alarms and give improved immunity against EM noise. In case
of important events, i.e. alarms and faults, can be the UWI-IQ input signals tested repeatedly in queue of samples which number is possible to set by
configuration option and the alarm or fault is indicated only if all samples in queue are tested as active. If any sample in this pre-alarm period is tested as
normal, the number of tested samples in queue is reset. (Default set is 2 samples)
The optional delay between received message and relevant output change can be set in addition. The receiving message is indicated during the running delay
period and allows possible action of the user before UWI-IQ outputs activation. (Default set is 0)
The software of the interface microcontroller serves for following tasks:
•
input signal processing (digital filtering) - the similar signal filtration as in ICAS CHOR-IQ is used
•
update of two status words - the first serves for the internal interface status, the second one for the loop status
•
generation of the output message for wireless loop depends on actual interface status
•
wake up of the radio-module and control the data /message/ exchange between radio-module and interface
•
SPI master for communication between radio-module and the in built interface microcontroller
•
received message analysis and loop status word update
•
indication of the UWI-IQ status
•
indication of the link status - remote events indication by LEDs, relays and Loop output control
•
test processing and indication
•
memory check and system error indication
•
pushbutton interrupt processing and intelligent response to pushbutton activity which depends on current detector and loop status
•
input delay adjustment (filtering set)
The software of the radio-module serves for the following tasks:
•
Operation for joining or deleting from the specific loop, loop creating - learn mode indication
•
Wake up from the SPI master and communication in SPI SLAVE mode with UWI-IQ interface (the new message is sent from radio-module into the
interface and a new message from the interface is sent into the radio-module at the same time)
•
Timing of transmitting time slots for wireless communication depends on its loop number in order to avoid communication collisions in one loop
•
Transmitting of the message from the interface into the loop or to the IQ control panel (depends on IQ System configuration)
•
Loop Message monitoring, processing and selection (the message from the loop is not automatically sent directly to the UWI-IQ)
Indication
There are one green, two red and two yellow LEDs for indication on the panel.
The green LED
(POWER)
serves only for the power supply indication.
Red LED (LOCAL ALARM/TEST)
it serves for indication of the local pre-alarm by flashing and following steady indication of full local alarm
it serves for the indication of the output delay after receiving of the F message (before Fire output activation)
it serves also for indication of TEST mode after receiving of T message or after TEST button short press
it serves also for indication of the new input delay, during manual delay adjustment procedure
