Description
Universal wireless interface UWI-IQ can serve either as a node of the ICAS
wireless IQ system with uCU-IQ control panel or two UWI-IQ units can be
used for wireless link, which is independent on IQ system.
The communication protocol is compatible with the ICAS IQ system. The
UWI-IQ is supposed to be powered from the device which is connected to
or from uPU-IQ. There are wide possibilities of user configurations
available, which allows to adapt the UWI-IQ to specific user application.
The configuration is designed as wireless and user friendly special PC
application - part of the RF monitor software tool, which serves for ICAS
wireless system configuration and monitoring.
Wireless link is able to secure transmission of two input signals from one
UWI-IQ unit by wireless to two relay outputs and loop option of the second
UWI-IQ unit, which are configured into a wireless link. (peer to peer
system configuration)
The UWI-IQ inputs are supposed to be connected to potential-free contacts
and can be configured as NC or NO which is possible to set for each input
individually.
( typically relay outputs of IRS-3 or control panels or open collector outputs
possibly). The corresponded alarm/fault message is sent after the contacts
connected to UWI inputs are switched on (NO config.) / switched off (NC
config.). After its releasing/ connecting is sent the corresponded stop alarm/
stop fault message then.
UWI-IQ allows to indicate power supply on by green LED, activity on
inputs and running pre-alarm (inputs delay) or outputs delay from the
remote alarm/failure message by yellow and red LEDs - the red LED
serves also for Test indication.
The next two LEDs serve for indication of received messages (remote
events) at the same time with relevant outputs activity.
Fire ALARM relay is activated after receiving of the fire alarm message -
the loop optional output will increase the current. The FAULT relay is
activated after receiving of the fault message.
It is possible to set in UWI-IQ configuration the outputs / relays response
also to local events and also it is possible to set delay of the output after
alarm/fault message receiving.
If a control panel wired loop is connected to the UWI-IQ loop terminal
instead of EOL resistor, the normal loop current flows through the UWI-IQ
in normal condition. There are available two different levels of the normal
loop current - corresponds to IMC-Mx panels or to IFP-2.32 panel. The
switch on position J3 on the UWI-IQ Terminal board serves for an easy
choice of the required normal loop current level.
The UWI-IQ will increase the loop current after the fire alarm message
receiving to the fire alarm level, for the connected control panel.
The fault is indicated by interruption of the loop after fault message
receiving - the loop current gets down and it will affect loop fault indication
on the connected control panel.
(Typically application - transmission of FIRE ALARM and FAULT signals
between two UWIs, - for example from remote IRS-3 aspiration detector
to a standard ICAS control unit - IMC-MD, IFP2.32 etc.)
The same kind of UWI-IQ model can serve either as wireless transmitter or
receiver or as a node of ICAS IQ system on the detector level.
UWI-IQ unit can serve also as an universal interface for ICAS IQ system
with uCU-IQ control panel(s). In this configuration the UWI-IQ unit
occupies one detector position in the system configuration.
There is an easy adjustable delay available for fire alarm and fault
messages. After appearing of alarm condition on an input, the message is
not sent immediately, but after a pre-alarm time. The alarm/fault is tested
repeatedly with period about 4 s and only after the specified number of
positive tests is reached, the corresponded message is transmitted.
The required pre-alarm period (input delay) is easy adjustable by user in
steps about 4s. The easy way to set is to use the RF-monitor and set the
required delay in the UWI-IQ configuration page.
The stop alarm/ stop fault messages are not delayed.
The UWI-IQ is able to send and receive both alarm and fault signals
sequentially. In case the both alarm and fault signal are received, the both
relays are activated and the alarm status has priority on the loop optional
output.
It is possible to set also an output delay, which is an adjustable delay
between receiving of the alarm or failure message and a correspondent
output activities. This delay is user adjustable from the UWI-IQ
configuration page of the RF - monitor.
Testing & Delay setting.
The UWI-IQ can be tested by the TEST button. It is possible to test the
radio-communication this way- short press of the test button evokes
transmitting of the Tests / Reset message depends on current UWI-IQ
status - normal / test mode.
The UWI-IQ gets from normal to test mode either by test button activity
or after receiving of the test message from another component in
wireless system configuration.
As soon as the Test mode is enabled, the outputs of the UWI-IQ unit
will follow its inputs, which allows to test the hardware easy. The
transmitting of alarm/failure messages is kept in the test mode too.
The test mode can be stopped by the Test button or by receiving of the
reset message.
Test mode will be reset automatically in about 3 minutes if any reset
message or button activity is not coming.
The response to the alarm/ fault events on UWI-IQ inputs can be
delayed. The delay of the correspondent message sending is determined
by number of input tests after the input signal level change from normal
to alarm / fault condition.
The response to the alarm/fault disappearing ( to the change of the
signal level to normal level ) is not delayed.
The default value of the delay is set to 2 (2 samples = 2 x 4s)
The delay ( number of samples) is possible to change or check by PC
with RF monitor software .
UWI-IQ allows an alternative set of a new input delay without PC
assistance by a long press of the Test button. For the new delay set
press the test button till appears the long yellow LED light and
following required number of red flashes .
Every red flash during this set up routine means an incrementing of
the number of signal samples between input change and message
sending (Increasing of the delay with next 4s.)
You can check the current delay easy by an intended shortage of an
UWI-IQ input and counting of flashes during the pre-alarm time.
The output delay is possible to set/change only from the RF-monitor ,
the default set is 0. If an output delay is set, the indication of the output
delay will start after alarm/fault message receive by double flash of red
or yellow LEDs (depends on received message F or E) with period
about 4s. After the output delay time-out the double flashes stopped and
UWI-IQ gets to the standard event indication and correspondent relay
and loop output is activated.

Installation
1. Configure wireless communication system with control panel or peer
to peer loop (UWI-IQ to UWI-IQ link) before units placing (see
Appendix 2 or 3 for details)
2. Connect the power supply (9-12V DC) to the terminals POWER
3. Do it for both UWI-IQ which should be configured in wireless link.
In case of configuration UWI-IQ into uCU-IQ system connect also
batteries to all wireless detectors in the system. During the start up
time, the detector and UWI-IQ will give 2 short yellow blink every 4.
sec. in 30 sec. (Do not forgot to Delete previously UWI-IQ
configuration if any )
4. Follow the instruction from the manual for RF monitor -
configuration software and configure wireless system or wireless
link (UWI-IQ to UWI-IQ - peer to peer). (Wireless link is possible to
configure the same way as peer to peer CHOR-IQ detector loop.)
5. Select the UWI-IQ for user configuration by RF -monitor, open the
UWI-IQ configuration page and set the required UWI-IQ parameters
like input delay, output delay, local relays response, response to Q
message, Hush enable/disable. Choose the parameters in accordance
to your intended UWI-IQ application. Set/check the configurable
parameters of all UWI-IQ in installation /system.
6. Choose the best place to fix the UWI-IQ unit with regards to an easy
connection with the source of the input signal and/or the receiver of
relay / Loop output signals and power supply source. Find an optimal
position especially with regards to the antenna. The antennas has to be
oriented so that the same polarisation of all wireless components in
system is secured. The UWI-IQ unit is possible to fix to a wall uCU-
IQ alike. UWI-IQ is intended to be installed into an instrument
distribution box. Install the UWI-IQ unit at least 0.5m from fuse box
or other electrical appliances. Be aware that EM disturbances can
harm the universal interface
7. Connect power supply wires and the input(s), outputs on the UWI-IQ
terminal board according to the intended UWI-IQ application. Fix the
UWI-IQ electronics into the plastic box and install the top panel.
(Remove the top cover of the UWI-IQ carefully. Put a flat
screwdriver to the left side of cover groove and slightly lever to left
side and remove the top cover. Place the UWI-IQ in vertical position
into instrument distribution box. Use 2 screws to connect both sides
of the UWI-IQ to the box. Put the top cover of UWI-IQ backpanel.)
8. If external antenna is used, check carefully the antenna connection
(correct coax connection of the pigtail on RM module and
connection of the antenna to the pigtail by SMA connector.)
9. Check the Test broadcasting in the system. Test can be stopped by
press of any UWI-IQ or detector test button or from the control
panel. The test mode will stops automatically in about 3 minutes.

UWI-IQ custom configuration:
This feature allows to adapt the UWI-IQ to specific application.
UWI-IQ is equipped by the special configuration register and by two delay registers, which are allocated in the EEPROM memory.
The configurable parameters can be changed wireless from UWI-IQ configuration page of the RF-monitor PC tool.
The following UWI-IQ parameters are configurable:
• Input delay 255 steps ( one step is about 4s) Default 2
• Output delay 255 steps ( one step is about 4s) Default 0
• INP 1 (Fire input) level Normal open / Normal closed Default NO
• INP 2 (Fault input) level Normal open / Normal closed Default NO
• Q response Disabled / Enabled Default Disabled
• Hush response Disabled / Enabled Default Disabled
• Repeater Disabled / Enabled Default Disabled
Input delay
If an input delay is set, and the UWI-IQ input level is changed from normal to active level, the alarm/fault message is not sent immediately , but only if the
active level is kept during the pre-alarm / pre-fault indication period. The running pre-alarm period is indicated by flashes of correspondent LED (Red/Yellow)
every delay step. If the input level is changed to normal during the pre-alarm, the pre-alarm indication stops and the delay counter value is renewed, so that for
the alarm message is necessary to keep the input active for the whole pre-alarm delay against.
Output delay
If the message F or E is received and an output delay is set in the current UWI-IQ configuration, the outputs (relay and loop) will not get into alarm/fault state
immediately, but after the configured delay period.
The running delay has been indicated by double flashes each delay step since the message has been received. When the button is pressed during the running
output delay or RESET message or possibly Q message (if enabled) is received, no change of outputs come up and the delay and delay indication is reset.
INP 1, INP 2 level
As default the open input is evaluated by UWI-IQ as normal, whilst the closed input is considered to be alarm, resp. fault active signal.
It is possible to set by the configuration option an individual input to be evaluated if closed (shorted) as normal and open (disconnected) input is evaluated as
alarm/fault active signal then.
Q response
It is possible to enable in the configuration menu the response to Q-message. If Q response enabled the remote alarm/fault or running output delay are reset
after Q message receiving (CHOR-IQ detector alike) If disabled the only possibilities how to stop the remote alarm (output activity) are Reset message or
local button press.
Hush response
If Hush response enabled, a period, during which the UWI-IQ does not response neither to local input change nor to remote alarm / fault message can be
started . It will start either after H message receiving or when the button is pressed till red led TEST gets dark against.
Repeater
If this optional feature is enabled, the UWI-IQ is also forwarding the received messages. This option is available only for peer to peer system configurations.(In
system configuration with control panel uCU-IQ serves Repeater-IQ for possible message forwarding. )
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Example of a configuration screen and customer setting:
(Inputs are opened in normal condition, ALARM or FAULT can be activated shortage of the INP1 or INP 2)
(Q response is suppresed, Relays and loop output will response also to local events and Hush can be activated either by button or by instruction. )

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 terminals +/- 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

Yellow LED (LOCAL FAULT/HUSH) it serves for indication of pre-fault by flashing and following full indication of local fault
it serves for the indication of the output delay after receiving of the E message (before Fault output activation)
it serves for indication of start up time and manual reset acceptation
it can serve optionally also for indication of any local internal UWI-IQ fault
Red LED ( REMOTE ALARM) it serves for indication of received F message (the relay FIRE and LOOP output get into ALARM state)
it gets dark after receiving of S or R messages or after Q message if enabled
Yellow LED ( REMOTE FAULT) serves for indication of received E message (the relay FAULT and LOOP output get into FAULT state)
it gets dark after receiving of C or R messages (if both F and E message are received, the LOOP will be in FIRE
state, the both relays FIRE and FAULT will be activated) It can gets dark even after Q message if enabled

until receiving of stop fault (c), reset (r), quit (q) if enabled
or quit by a short Test button press
If output delay is set, the Red Led (LOCAL ALARM / TEST) is double flashing
during the delay first.
Remote Test Indication by RED LED ALARM/TEST 't' 'T'
automatic recovery after about 2 min
Quit: Message 'q' stops all remote indications (cancel an actual remote alarm or remote error) 'q' 'Q'
this operation can be activated by Test push button on any node in remote alarm
or from a control panel. Acceptation of Q message by UWI-IQ depends on configuration,
The Q response must be enabled (Disabled as default)
the local alarm is kept – it allows to find (localize) node with local alarm/local error
(If the button of node with local alarm is used the all detectors will stop sirens)
Reset: By the push button from the Test mode or by the message 'r' 'r' 'R'
It clears the UWI-IQ indications and status words – the local alarm, local fault, remote
alarm, remote error
(Reset can by applied even in local alarm /fault condition, but the Interface will indicate
the pre -alarm and alarm or pre-fault and fault condition against then)
Restart: the Interface is restarted the same way as after a power voltage on 'X' Identification
Restart can be done by power voltage (off /on) sequence or by a long push of the detector
button or

SPI message structure and instruction set (the same structure and instruction set is used for both ICAS wireless system or OEM system)
SPI message structure:
// CMD // PTYPE // DATA_1 // DATA_2 // DATA_3 // DATA_4 // CRC// where
CMD = F0 ..... Data read/write operation code
PTYPE = 84 ..... code for full duplex communication 80+ data block length
DATA_1 = master data - actual chamber value * / slave data - source component ID number **
DATA_2 = master data - average chamber value * / slave data - source subloop ID number **
DATA_3 = master data - status byte of the detector* / slave data - source zone ID number **
DATA_4 = master data - detector info (ASCII code upper case ) / slave data - loop info (ASCII code - lower case)
CRC = ((CMD) xor (PTYPE) xor (DATA_1) xor (DATA_2) xor (DATA_3) xor (DATA_4) xor (5F)) for the master message
CRC = ((PTYPE) xor (DATA_1) xor (DATA_2) xor (DATA_3) xor (DATA_4) xor (5F)) for the slave message
* these data are not broadcasted by IQRF radio-transceiver
** these data are not evaluated by the detector / serves for control panel operations
The Interface microcontroller serves as the SPI master for a communication between the IQRF radio-module and the in built Interface microcontroller.
The SPI slave (radio-module) is waken up periodically and the message from SPI master to SPI slave and from SPI slave to SPI master are exchanged at the
same time. The SPI message includes 4 data bytes due to compatibility of the protocol with µCU-IQ, but for the Interface is mostly important the last data byte
only, on this data position is sent a code which informs about Interface events and received code with information/instruction from the SLAVE module (loop
info). If instruction code is 'w' , the other bytes are used for UWI-IQ configuration:
- the first byte is interpreted as the new input delay
- the second byte is interpreted as the new output delay
- the third byte is interpreted as a new configuration byte CFG with following meanings of single bits:
CFG Configuration byte structure:
FIN ALARM INPUT CONFIGURATION - 0: NO - input active if closed /// 1: NC - input active when open
EIN FAULT INPUT CONFIGURATION - 0: NO - input active if closed /// 1: NC- input active when open
REL Outputs response to local events - 0: response only to remote events /// 1: response to local or remote alarm/fault
QRE Q Response - 0: Q response is blocked (default) /// 1: response to Q instruction enabled
RFT special RF communication test - not applied (the compatible standard communication test is solved in the system with uCU-IQ )
HRE H Response - 0: HUSH function is disabled /// 1: HUSH function and response to H enabled

ICAS instruction set (ASCII code interpretation):
Code set transmitted by UWI-IQ interface (by MASTER) Code set accepted from SLAVE (from the radio-module) and evaluated by Interface
code detector status code code interpretation
F local fire alarm info f request for remote alarm indication
S stopped local fire alarm info s request for remote fire alarm indication stop
E detector /chamber/ error info e request for remote error indication
C stopped error or low battery info c directive to suppress the remote error , low batt and com. lost indication
Q request to stop all remote events indications q directive to stop all remote evens indication incl. remote alarm)
T test request w instruction before special EEprom update operation
R loop reset request r RESET directive - stop all detector indication of both remote and local events
(the detector in the alarm condition gets into hush first)
N no significant event i request for basic detector status info
k request for communication lost indication
X info about RESTART x for detector RESTART
Z data after w directive was not accepted

The switch at the position J3 on the terminal board allows to choose between IFC and IMC control panels and the loop current is switched to a correspondent
standby level automatically at the same time.)
