AJAX ocBridge Plus User manual

ocBridge Plus User Manual
Updated March 6, 2021
Wireless sensors’ receiver ocBridge Plus is designated for connecting
compatible Ajax devices to any third party wired central unit (panel) with a help
of NC/NO contacts. Ajax system has two-way connection with the sensors
which enables it’s functioning in two modes: active mode and passive mode.
When the system is in passive mode, wireless sensors switch to power-saving
mode, which makes it possible to extend signicantly battery life.
If the receiver ocBridge Plus is connected to the wire central unit, the digital input «IN»
(wire input) MUST have connection with relay output or transistor output from the central
unit, and this output must be inverted when the central unit is being armed or disarmed.
Detailed description of connection to the central unit described in Managing the central
unit.

«10» (Picture 1).
If it is the rst connection, wait until the system identify new device and install
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.
In the archive vcpdriver_v1.3.1_setup.zip on CD you can nd two les:
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.
Please note that if you initially install an unsuitable driver and then install the
correct one over it, ocBridge Plus will not work with the PC’s congurator
program!
If the wrong driver was installed, at rst, 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 newer version) should be
installed. After drivers installation, launch the program «Ajax ocBridge Plus
congurator».
Consults Using conguration software of this manual provides the details about
the program «Ajax ocBridge Plus congurator» functioning. In the program

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

Picture 3. Adding a zone
Then, appropriate “Zone type” and settings is to be selected (consult Managing
the central unit of the present manual). To add a device chose necessary zone
and click “Add a device” button. Then, a “Adding new device” window appears
and it is necessary enter sensor’s identier (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 during
one minute, it means that the sensor is not registered! The light blinks in the
same way if the sensor is deleted from the ocBridge!

Picture 4. Device registration window
3. If the sensor was mistakenly registered in a wrong zone, click on its
“Properties” button. The settings window will appear permitting to select a new
zone for the sensor (Picture 5). You can also open the detector properties menu
by clicking the corresponding button opposite the detector in the general list of
the “Radio devices” tree.
Picture 5. The sensor’s properties’ menu makes it possible to register the sensor
in the zone
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.
4. When the sensors are successfully registered in the security system, click the
button “Write” (Picture 4) to save sensors’ conguration data in the ocBridge
Plus receiver’s memory. When ocBridge Plus connected to the PC, click the
button “Read” (Picture 4) to read the pre-saved sensors’ conguration from the
ocBridge Plus memory.
Make sure that installation location of sensor, has a stable radio contact with the
ocBridge Plus 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, bridgings, as well as the thickness and constructional material. The
signal loses a power passing through barriers. For example, distance between the
detector and receiver that 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 signicantly the quality radio signal between the sensor and the ocBridge Plus.
5. Select an appropriate place to install the sensors.
Please check the signal level of the connected devices! The radio signal test you
can nd on the page “System’s monitor” of the conguration software. To start
radio signal test press the button with antenna against the selected sensor
(Picture 6) (only when the sensors are in the operating mode and there is no red
light).
Picture 6. “System monitor” page
Picture 7. Signal level

The results of the test are shown in the conguration software (Picture 7) as 3
indication bars, and by the sensor light. The test results can be the following:
Receiver Sensor 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

and for reading current conguration settings (Sensors’ handling).
6. “Events memory” page stores information about alarming events (Picture 12),
service events (Picture 13) and statistics tables (Picture 14). 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 le”, it is possible to save the events logs in xml format which can be opened
with Excel.
nd the information on the current software version;

Events in all logs are displayed chronologically, starting from the rst 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.
Picture 13. Service eventlog
With the statistics table (Picture 14) it is easy to handle important data from
each sensor: sensor’s location in specic 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.

7. The page “System’s monitor” is designated for sensors’ state control and for
tests of their radio connection. The sensor’s current state is dened with its
background lighting color (Picture 15):
Picture 15. The connected sensors are entering to working mode
8. In the bottom of “System monitor” (Picture 16) the information is displayed
about:
white background — the sensor is connected;
gray background — the connected detector starts operation, ocBridge Plus
waits for the detector to send its rst status and will transmit the current
system settings in response to it;
light-green lighting (during 1 second) is turning on when the status is
received from the sensor;
orange lighting (during 1 second) is on when the alarm signal is received
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.

5. countdown timer of the sensors’ current poling period.

9. The detection area test (Picture 16) is required to make sure that the sensors
are working ecient in their current position. In testing mode the sensor 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 key fob does not support the detection area tests and radio
signal tests.

Managing the central unit
1. It is necessary to install the ocBridge Plus 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 Plus board, there are pads for installing SMA-sockets for external
antennas.
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 Plus’s radio
antennas must be as far as possible from the alarm system GSM-module in case there is
such a module.
2. With a help of ordinary wires, the receiver’s outputs (PictureS 17, 18) are
connected to the alarm system central unit 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 Plus. The ocBridge
SpaceControl

Plus 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!
3. The outputs with numbers 1–8 (Picture 17) correspond to 8 main nominal
alarm zones.
Picture 17. Main outputs and input “IN” of the receiver
Other 5 outputs of ocBridge Plus are service zones and correspond to the
service inputs of the alarm system central unit.
Picture 18. ocBridge Plus receiver’s service outputs and power supply

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:

4. Zones are divided into 3 types: alarm zones, automation zones and
arm/disarm zones (Picture 19). Zone type is selected when the zone is created,
consult Sensors’ handling.
Picture 19. Selecting zone type
The alarm zone can be set (Picture 20) as NC (normally closed contacts) and as
NO (normally opened contacts).

Picture 20. Alarm zone settings
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 20). 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 21). 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.
Picture 21. Automation zone settings
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 key fobs and keyboards connection (Picture
22).

Picture 22. Arm/disarm zone settings
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.
5. 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 Plus 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 Plus and sensors to “passive”. Use of “passive”
mode of the sensors when system disarmed will signicantly improve battery
life of the sensors.
While connecting the key fob 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 nancial
institutions). When the polling period is too long, the time span of statuses sending from
the sensors is increasing, which inuences secure system’s reaction to service events
(e.g. lost connection event). The system always reacts immediately to alarm events with
any polling period.
6. 4 outputs (T, S, B, J) correspond to service zones (Picture 18). 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 conguration software (Picture 22).
Picture 23. Service outputs setting menu on page “Radio zones”
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 24). By default, the impulse time is
1 second and the maximal value is 254 seconds.

Picture 24. Service outputs’ properties menu Т, B, J
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 25). By default, if
ocBridge Plus does not receive 40 heartbeats from sensor successfully, it
generates an “Lost connection” alarm.
Picture 25. Service output S properties menu
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 key fob 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 dened as a bistable one; it turns on for the number of
seconds specied (1-254 seconds) if the zone was dened as an impulse one.
