CONNECTIONS (OXYGEN 3 and 3 ST)

CONNECTOR PIN-OUT

Description

n.c.

Tel line

n.c.

This unit allows the connection on parallel of a standard telephone set (for dialling services). Please note that „Phone‟

socket is always active (i.e. it doesn‟t depend on the „Hook‟ button state) and it has the same Pin-Out as the LINE socket.

Should the device be put out of action due to being struck by lightning or excess voltage, disconnect

it from the telephone line without delay. Do not reconnect until the device has been checked. If in

doubt contact the technical support service.

Make sure there is suitable lightning protection to protect the device.

Alternatively you should disconnect all connectors from the device during a storm or when the device

is going to be unsupervised or not used for a longer period of time. These measures will protect

against damage by lightning or excess voltage.

Other connections:

R/L (OUT REC on PIN RCA): double mono output which allows recording of the telephone calls (either SEND or

RECEIVE signals).

CALL (terminal board connector): connector for external call signalling. A photocoupler inside the module closes when a

telephone call comes (ring).

NOTE: Typical current allowed on the photocoupler: 5 mA (max 10 mA). Max voltage allowed: 15 V.
