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. )
