Interfacing To The External I/O - Panasonic KX-HCM230 Operating Instructions Manual

4.2 Interfacing to the External I/O

The Alarm mode in the Image Transfer feature requires the external sensors/
devices to be connected to the External Sensor Input of the External I/O. Certain
features of this Network Camera can be activated by an external sensor that
senses physical changes in the area Network Camera is monitoring. These
changes can include motion detection or a physical change in the monitored area.
The external sensor can also be a door switch or an infrared motion detector.
These devices are customer provided, and are available from dealers who carry
surveillance and security products. Electrically, they must be able to provide a
momentary contact closure.
Pin
1 GND
2 DC Power Output Terminal
• 12—16 V DC
• Maximum of 100 mA load drive is possible.
3 External Sensor Input
• External Sensor Input receives the signal produced by the alarm
sensors, (e.g., door sensor, infrared ray sensor). Those signals can
activate Image Transfer in the Alarm mode feature on page 68.
• Use it by opening or GND short-circuit.
4 External Device Control Output
• External Device Control Output sends the electric current to activate
the external devices, (e.g., light, buzzer).
• External Output Control window can set the External Device Control
Output. Refer to page 83.
• It is an open collector circuit, and the maximum drawing-in current is
100 mA. Prevent the maximum voltage from exceeding DC Power
Output voltage of pin 2.
