Installing and Connecting the Unit

To connect the unit analog video output to an analog device

 Using video coax 75Ω cable with BNC connectors, connect the VIDEO OUT of the ioimage unit to

the analog device Video Input (for example, the VIDEO IN of a monitor or DVR).

Note:

Make sure the ioimage unit and the external analog equipment support the same

video standard (PAL/NTSC).

3.2.7 Connecting the Unit to Receive Alarms from External Devices (Alarm Inputs)

The unit supports receiving alarms from external devices such as sensors and doors, enabling it to trigger

automatic responses on the unit. The unit supports a single alarm input from an external device. The alarm

input includes two connecting terminals.

Warning:

Only dry contacts can be connected to the unit’s ALARM IN terminals. An external device

must fully close or fully open the circuit between the unit’s ALARM IN terminals.

Avertissement:

Seuls des contacts secs peuvent être branchés aux terminaux ALARM IN de l'unité. Un

appareil externe doit complètement ouvrir ou complètement fermer le circuit entre les

terminaux ALARM IN de l'unité.

To connect an external alarm to the unit

Warning:

Disconnect power from the unit before performing the following procedure.

Avertissement:

Débranchez l'alimentation de l'unité avant d'effectuer la procédure suivante.

1. Connect the leads from the external device dry contact output using the spring clamp terminal

block into the terminals marked ALARM IN (-) and (+). See Connecting Leads to a Spring Clamp

Terminal Block (page 19). The two terminals are located at the bottom of the terminal block. See

Figure 3: trk-101-P Power Connection Panel (page 2).

2. Connect the terminal block to the external devices connector on the power connection panel of

the unit. See Figure 3: trk-101-P Power Connection Panel (page 2).

3. Connect the other end of the cable to the alarm out (dry contact) of the alarm device/sensor.

3.2.8 Connecting the Unit to Control an External Device (Using Relay Outputs)

You can use the relay output of the unit to provide an indication signal for controlling external devices, such

as door locks, lights, etc. The relay output of the unit can be activated as a response to events and alerts.

For more information on incident responses and relay outputs, refer to the HTML Edition Units User’s

Guide.

Warning:

The signal from the relay output of the unit must be used as an indicator and not for direct

control of a device.

Avertissement:

Le signal provenant de la sortie relais de l'unité doit être utilisé comme indicateur et non pas

pour contrôler directement un appareil.
