SENSORS’ HANDLING

Connect the bridge to the computer with the help of USB cable (type А–mini USB) through connector «4» (PICTURE 1). Turn on the receiver with the switch «10» (PICTURE 1). If it is the first connection, wait until the system identifies new device and installs the software drivers. If the drivers were not installed automatically, you will have to install the driver program vcpdriver_v1.3.1 manually. There are different versions of this program for x86 and x64 Windows platforms. You can find two files: VCP_V1.3.1_Setup.exe for 32-bit Windows operating systems and VCP_V1.3.1_Setup_x64.exe – for 64-bit Windows operating systems on the CD. If the wrong driver was installed, at first, it is necessary to uninstall it (through Windows programs uninstall), then reboot the computer and install the necessary software driver. Also, NET Framework 4 (or a newer version) should be installed. After driver installation, launch the program «Ajax ocBridge configurator». Paragraph 5 of this manual provides the details about the program «Ajax ocBridge configurator» functioning. In the program settings in «Ajax ocBridge configurator» settings (menu «Connection» – «Setting»), select the COM port that is chosen by the system for the receiver (PICTURE 2), click «OK» and then the «Connect» button. «Ajax ocBridge configurator» is ready to work with the ocBridge receiver.

INDICATION DESCRIPTION

• Greenlight is permanent, red light does not blink OcBridge is in configuration mode. In the configuration, there are Pages “Radio zones” or «Events memory» are opened. During this period, the sensors do not receive responses to the alarm signals and statuses.
• Green – blinks once per second (before, the green light was permanent), and the red – blinks during 30 seconds New radio set unit detection mode is on.
• The red blinks momentarily A moment when the ocBridge receiver registers a new device.
• The green – blinks for 10 minutes and the red is permanent; no red light Searching for all devices after the previously saved PC configuration is downloaded,the system is armed; the system is disarmed.
• No green and red lights The receiver is in in operating mode, and the system is disarmed.
• Permanent red light The receiver is in operating mode, the system is armed.
• Permanent green light, the red light is blinking very fast Radio signal is tested in order to connect a sensor or another device.
• The green light blinks momentarily New detectors’ polling period started, 36 seconds by default.
• Red/green- blinks momentarily Failure is detected

All devices that you want to connect to the ocBridge must be registered with a help of «Ajax ocBridge configurator». In order to register the sensors, it is necessary to create radio zones in the configurator in case of it had not been done before. To do this select the “Radio zone” and click «Add zone» button (PICTURE 3).

Then, appropriate “Zone type” and settings is to be selected (consult paragraphs 6.4 and 6.6 of the present manual). To add a device chose the necessary zone and click the “Add a device” button. Then, a “Adding new device” window appears and it is necessary enter the sensor’s identifier (ID) applied on it below QR code, then click the “Search” button (PICTURE 4). When the search indicator bar begins to move, it is necessary to turn on the sensor. The registration request is sent only when the sensor is being switched on! In case of the registration fail, turn off the sensor for 5 seconds and then turn it on again. If the sensor is on and its light blinks once per second for one minute, it means that the sensor is not registered! The light blinks in the same way if the sensor is deleted from the bridge!

If the sensor was mistakenly registered in the wrong zone, click on its “Properties” button. The settings window will appear permitting to select a new zone for the sensor (PICTURE 5).

• When an additional wire sensor is connected to the external digital input of the wireless sensor, in the properties activate the checkbox “Additional input” (PICTURE 5). If a sensor (for example, a LeaksProtect) is designed for working 24 h, activate in the checkbox properties “24 h active”. 24 h sensors and normal sensors should not be placed in the same zone! If necessary, adjust the sensor’s sensitivity.
• When the sensors are successfully registered in the security system, click the button “Write” (PICTURE 4) to save the sensors’ configuration data in the Oxbridge receiver’s memory. When ocBridge is connected to the PC, click the button “Read” (PICTURE 4) to read the pre-saved sensors’ configuration from the ocBridge memory.
• Select an appropriate place to install the sensors.

ATTENTION
Make sure that the installation location of the sensor has stable radio contact with the ocBridge receiver! A maximum distance of 2000 m (6552 ft) between the sensor and the receiver is mentioned as a comparison with other devices. This distance was found is as a result of open-area tests. Connection quality and distance between the sensor and the receiver can vary depending on installation location, walls, compartments, and bridgings, as well as the thickness and constructional material. The signal loses power passing through barriers. For example, the distance between the detector and receiver divided by two concrete walls is approximately 30 m (98.4 ft). Take into consideration, if you move the sensor even 10 cm(4 in), it is possible to improve significantly the quality radio signal between the sensor and the bridge.

Please check the signal level of the connected devices! The radio signal test you can find on the page “System’s monitor” of the configuration software. To start radio signal test press the button with the antenna against the selected sensor (PICTURE 6) (only when the sensors are in operating mode and there is no red light).

The results of the test are shown in the configuration software (PICTURE 7) as 3 indication bars, and by the sensor light. The test results can be the following:

RECIEVER SENSOR’S LIGHT EMITTING DIODE DESCRIPTION

• 3 indication bars lights permanently, with short breaks each 1.5 seconds excellent signal.
• 2 indication bars blinks 5 times per second medium signal.
• 1 indication bar blinks twice per second low signal no bar Short flashes each 1.5 seconds no signal.

ATTENTION
Please install the sensors in the places with the signal level of 3 or 2 bars. Otherwise, the sensor may function inconsistently.

The maximum number of devices that you can connect to the ocBridge depends on the polling period.

SENSORS’ QUANTITY POLLING PERIOD

• 100 36 seconds and more
• 79 24 seconds
• 39 12 seconds

USING CONFIGURATION SOFTWARE

File” menu (PICTURE 8) allows to:

• save active configuration of ocBridge settings in file on PC (Save configurations to file);
• upload to ocBridge the settings’ configuration saved on the computer (Open the existing configuration);
• start the firmware upgrade (Firmware update);
• clear all settings (Factory reset). All the data and previously saved settings will be deleted!

“Connection” menu (PICTURE 9) allows to

• select COM port for ocBridge connection to the computer (Settings);
• connect the ocBridge to the computer (Connection);
• disconnect ocBridge from computer (Disconnection);

On page “Radio zones” (PICTURE 10) it is possible to create required the detection zones areas required and to add there sensors and devices (consult paragraph 4.2) and also to set the additional parameters of sensors’, devices’ and zones functioning (consults paragraphs 6.4-6.6).

The buttons “Write” and “Read” are used for saving data in ocBridge memory and for reading current configuration settings (paragraph 4.4).

Events memory” page stores information about alarming events (PICTURE 11), service events (PICTURE 12) and statistics tables (PICTURE 13). It is possible to renew information in data logs or to clear them with “Log reset” button. The logs contains up to 50 alarming events and 50 service events. With the button “Save in file”, it is possible to save the events logs in xml format which can be opened with Excel.

Events in all logs are displayed chronologically, starting from the first one and ending with the last one. The event number 1 is the last event (the most recent event), the event number 50 is the oldest event.

With the statistics table (PICTURE 13) it is easy to handle important data from each sensor: sensor’s location in specific zone and in general in the network; to observe the battery state in each sensor; to track the tamper buttons’ state in all sensors; to see which sensor generated the alarm and how many times; to estimate the signal stability according to data on signal failures. In the same data chart, there the service data is displayed – sensor’s name, device type, its ID, zone number / zone name.

The page “System’s monitor” is designated for sensors’ state control and for tests of their radio connection. The sensor’s current state is defined with its background lighting color (PICTURE 14):

• white background – the sensor is connected;
• light-green lighting (during 1 second) is turning on when the status is recieved from the sensor;
• orange lighting (during 1 second) is on when the alarm signal is recieved from the sensor;
• yellow lighting – the sensor’s battery is low (only the battery level is illuminated);
• red lighting – the sensor is not connected, it is lost or not in working mode.
  ***** – means the connected sensor is entering in operating mode, ocBridge is waiting for the sensor to send its first status in order to send in response the current system settings;

In the bottom of “System monitor” (PICTURE 14) the information is displayed about:

1. current connection to the computer;
2. background noise level;
3. alarm and service zones condition (active zones are highlighted);
4. current alarm system state (activated/deactivated);
5. countdown timer of the sensors’ current poling period.

The detection area test (PICTURE 15) is required to make sure that the sensors are working efficient in their current position. In testing mode the sensor’s light is on permanently, switching off for 1 second while activation – it is very easy to observe. In contrast to radio signal test, the detection area test for several sensors simultaneously is possible. For this, choose the check-box against each device in the window “Area detection test”, having opened previously the test window by pressing the button of magnifying glass against the selected sensor. The SpaceControl keyfob does not support the detection area tests and radio signal tests.

MANAGING THE CENTRAL UNIT

It is necessary to install the ocBridge near the alarm system central unit (panel). Do not install the receiver in the metal box, it will worsen considerably the radio signal receiving from the wireless sensors. If installation in the metal box is indispensable, it is necessary to connect an external antenna. On the ocBridge board, there are pads for installing SMA- sockets for external antennas.

ATTENTION
When connected to the central unit, the wires (especially the power wires) must not touch the antenna as they can worsen the connection quality. ocBridge’s radio antennas must be as far as possible from the alarm system GSM-module in case there is such a module. With a help of ordinary wires, the receiver’s outputs (PICTURES 16, 17) are connected to the alarm system central unit’s inputs. Thus, the receiver’s outputs are analogues of ordinary wire sensors for the central unit inputs. When the wireless sensor is activated, it sends the signal to ocBridge. The ocBridge receiver processes the signal and opens (by default, the output can be also set for closing) the wire output corresponding to the sensor. The alarm system’s central unit reads the output opening as the sensor’s zone opening and sends an alarm signal. If it is mentioned that the central unit zone must have high resistance between the receiver’s output and the central unit zone, the resistor with nominal required by the central unit must be placed with serial connection. Observe the polarity while connecting the wires! The outputs with numbers 1–8 (PICTURE 16) correspond to 8 main nominal alarm zones.

Other 5 outputs of ocBridge are service zones and correspond to the service inputs of the alarm system central unit.

The table provides the description for main and service zones’ contacts:

Output № MARKING DESCRIPTION

1. 1 1st zone output
2. 2 2nd zone output
3. 3 3rd zone output
4. 4 4th zone output
5. 5 5th zone output
6. 6 6th zone output
7. 7 7th zone output
8. 8 8th zone output
9. (Input) IN wire input for connecting to the central unit output (for alarm system arming/disarming)
10. ground for connection to the central unit

13. T “Tamper” service output
14. S “Connection failure” service output
15. B “Battery” service output
16. J “Jamming” service output
17. T1 “Tamper” service output
18. ground for connection to the central unit

The receiver is connected to the central unit as explained by the scheme

Zones are divided into 3 types: alarm zones, automation zones and arm/disarm zones (PICTURE 18). Zone type is selected when the zone is created, consult paragraph 4.2.

The alarm zone can be set (PICTURE 19) as NC (normally closed contacts) and as NO (normally opened contacts).

The alarm zone reacts to bistable detectors (e.g. DoorProtect and LeaksProtect) with opening/closing, depending on setting “Initial state” (NC/NO). The zone is in alarm mode until the bistable detectors state returns to its initial state. The zone reacts to impulse sensors (e.g. MotionProtect, GlassProtect) with opening/closing depending on setting “Initial state” (NC/NO) with the impulse, its duration can be adjusted by the setting “Impulse time” (PICTURE 19). By default, the “Impulse time” is 1 second, 254 seconds maximum. If alarm is raised, the zone’s red light “3” is on (PICTURE 1). Automation zone can be set as NC or NO (PICTURE 20). When the “Impulse” way to react is chosen, the zones reacts to all activations with opening/closing, depending on “Initial state” setting for the time set in the setting “Impulse time” – 1 second by default and 254 seconds maximum.

When the “Trigger” reaction mode is selected, the zone output changes its initial state to the opposite one with each new activation signal. The light indicates the automation zone’s current state – with the activation signal, a red light turns on or turns off if the normal state is restored. With the trigger reaction mode, “Impulse time” parameter is unavailable. Arm/disarm zone is used only for keyfobs and keyboards connection (PICTURE 21).

Arm/disarm zone can be set to initial state NC or NO. When the keyfob is registered, in arm/disarm zone two buttons are added simultaneously: button 1 – arming and button 3 – disarm. To arm, the zone reacts with closing/opening the output, depending on the setting “Initial state” (NC/ NO). When this zone is activated, the red light corresponding to it turns on, and when it is deactivated, the light “3” (PICTURE 1) is off.

The activation/deactivation zone is set by default as trigger.

The input “IN” is designated for connecting transistor output or the central unit (panel) relay (PICTURE 1). If the “IN” input condition changes (Closing/Opening), the whole set of sensors connected to the receiver are set to “passive” mode (except for the sensors ticked as 24 h active), with the initial state restore – the sensors are set to “active”, and the red light is on. In case several groups of sensors are used independently on the central unit, the ocBridge is to be set to the “active” mode even if only one group of central unit is in armed mode. Only when all groups on central unit are deactivated, is possible to set the ocBridge and sensors to “passive”. Use of “passive” mode of the sensors when system disarmed will significantly improve battery life of the sensors.

ATTENTION
While connecting the keyfob to the wireless sensors’ receiver ocBridge, be careful in connecting the keyfob to the zones! Please, don’t connect the keyfob to the zones with bistable sensors. Do not forget: the longer the polling period (PICTURE 22) of the sensors is (it varies from 12 to 300 seconds, 36 seconds set by default), the longer is wireless sensors’ battery life! At the same time it is suggested not to use a long polling period in secure systems for places where delay can be critical (for example, in financial institutions). When the polling period is too long, the time span of statuses sending from the sensors is increasing, which influences secure system’s reaction to service events (e.g. lost connection event). The system always reacts immediately to alarm events with any polling period. outputs (T, S, B, J) correspond to service zones (PICTURE 17). Service zones are used for sending operation data to the central unit. Service outputs’ functioning is adjustable (PICTURE 23), they can be impulse of bistable ones. It is possible to switch off service outputs, in case they are not used in security system’s central unit (panel). To switch off untick the checkbox against an appropriate output’s name in configuration software (PICTURE 22).

If the Impulse mode is selected for reaction, the zone reacts to all activations by closing/opening the output depending on “Initial state” setting (NC/NO) for the time set in “Impulse time” option (PICTURE 23). By default, the impulse time is 1 second and the maximal value is 254 seconds.

When bistable mode is chosen for reaction, service zone reacts by closing/ opening the output depending on “Initial state” setting (NC/NO) until the zones returns to the initial state. When the initial state is changed, green light “12” of the appropriate service zone (PICTURE 1) turns on.Output T – “Tamper”: if one of the sensors is opened or separated from the assembling surface, its tamper button is activated and the sensor sends the alarm signal of opening/breaking. Output S – “Lost connection”: if one of the sensors does not send the status signal during check time, the sensor changes the output condition S. Service zone S will activate after the period of time equal to the parameter “Polling period” multiplied by the parameter “Passes number” (PICTURE 24). By default, if ocBridge does not receive 40 heatbeats from sensor successfully, it generates an “Lost connection” alarm.

Output B – “Battery”. When the sensor the battery has run down, the sensor sends the signal about it. When the battery has run down, zone “B” does not function for a keyfob SpaceControl, but the message about the battery running down can be found in service events log. On the keyfob, the discharged battery is shown by its light indication. Output J – “Jamming: in case it is found that the radio signal is being jammed, the receiver changes the output J condition. Indicator corresponding to the output J begins to light depending on the zone settings: the light is permanently on if the zone was defined as a bistable one; it turns on for the number of seconds specified (1-254 seconds) if the zone was defined as an impulse one. 6.7. Output Т1 is responsible for the ocBridge’s tampers’ state. When the receiver is installed in the box, tamper buttons are pressed, the output is permanently closed. When at least one tamper unpressed, the output is opening and the guard zone sends an alarm signal. It remains in alarm state until both tamper buttons are in normal state again and the output is closed.

FIRMWARE UPGRADE

It is possible to upgrade ocBridge’s firmware. Download latest version of software from www.ajax.systems. Firmware is upgraded with a help of configuration software. If the ocBridge is connected to configuration software, you should press “Disconnect” button without disconnecting the ocBridge itself from PC. Then, in the menu “Connection”, you should select a COM port where ocBridge is connected. Then, it is necessary to select “Firmware upgrade” in drop-down menu and then, pressing the button “Select file”, to show the file path to *.aff file with new firmware (PICTURE 25).

Then, it is necessary to power the receiver off with switch “10” (PICTURE 1) and turn the device on again. After switching on, the upgrade process begins automatically. In case the process was accomplished successfully, there is a message “Software upgrade is accomplished” and the receiver is ready for work. If there is no message “Software upgrade is accomplished” or there were any failures during the software upgrade, you should upgrade the software again.

CONFIGURATION TRANSFER

It is possible to use the sensors’ configuration transfer to the other device ocBridge without having to register the sensors again. For the transfer, it is necessary to save the current configuration from “File” menu with “Save configuration to file” button (PICTURE 8). Then, it is necessary to disconnect the previous receiver and to connect a new one to the configurator. Then, it is necessary to upload there a configuration saved on the computer using the button “Open the existing configuration” and then to press the button “Write down”. After this, the window of sensors’ search will appear (PICTURE 26) on ocBridge and the green light indicator will blink for 10 minutes.

In order to save the sensors in the memory of new receiver, it is necessary to switch off the power switch on all the sensors alternately, to wait for some seconds for the capacitor of the sensors to discharge, and then to turn the sensors on again. When the sensors’ search is accomplished, the configuration will be fully copied to new ocBridge. Switching off power supply of the sensors is necessary in order to prevent the security system sabotage. If while sensors’ search you didn’t reload all sensors, the sensors’ search can be relaunched again in the menu “Connection” – “Read configured devices”.

MAINTENANCE

Once in 6 months, the receiver must be cleared of dust by aeration. The dust accumulated on the device can in certain conditions become current conductive and provoke the receiver’s breakdown or interfere with its functioning.

WARRANTY

The ocBridge receiver’s warranty period is 24 months.
