ocBridge Plus User Manual
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.

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.

Selecting zone type The alarm zone can be set (Picture 20) as NC (normally closed contacts) and as NO (normally opened contacts).
- Page 17 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.
- Page 18 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”.
- Page 19 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).
- Page 20 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.

Firmware is upgraded with a help of con guration software. If the ocBridge Plus is connected to con guration software, you should press “Disconnect” button without disconnecting the ocBridge Plus itself from PC. Then, in the menu “Connection”, you should select a COM port where ocBridge Plus is connected. -
