Connection of Alarm Input / Output Terminals Connection of Coaxial Cables

Connect the alarm input/output terminals to external devices such as sensors and buzzers.

AFollow the diagram below to loosen and remove the screws on the two edges of the terminal block.

BStrip the coating of the alarm signal cable by about 4 mm before inserting it into the terminal.

CTurn the screw on the side to fasten the alarm signal cable.

MEMO

If an RG-11 coaxial cable is used it cannot be connected directly to the terminal board. To use such a cable, connect an RG-59 cable to the camera and then connect the RG-11 cable to the RG-59 cable.

To increase cable extension, make use of thicker cables or a cable compensator.

The maximum extension distance varies according to the system in use as well as characteristics of the cable.

8Alarm Input Terminal

Connect this terminal to an infrared, door or metallic sensor, or to a manual switch.

Input non-voltage contact signal to the alarm input terminal to prevent internal circuit noises.

Do not supply voltage.

Use the menu to set whether to activate alarm when the contact is short (make) or open (break).

Ensure that the alarm signal input lasts for at least 200 ms. Otherwise, they may not be recognized as alarm

signals.

8Alarm Output Terminal

Connect this to alarm devices such as an annunciator, indicator, lamp or buzzer.

The alarm output terminal is a photocoupler-insulated open collector, which turns ON during an alarm.

As these terminals are provided with polarity. Ensure that voltage at the + terminal is higher than that at the - terminal. Application of reverse voltage in this case may cause the device to break down.
