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 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.
7. FIRMWARE UPGRADE
7.1. It is possible to upgrade ocBridge’s firmware. Download latest version
of software from
www.ajax.systems.
7.2. 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.
7.3. If there is no message “Software upgrade is accomplished” or there
were any failures during the software upgrade, you should upgrade the
software again.
8. 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.
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.
6.5. 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 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.
6.6. 4 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.
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.
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.
