Installation Example
Secure I/O 2 is connected with RS-485 and can be installed anywhere due to its small size. It can be installed with a
junction box or onto a wall control box already installed. It can be installed at the rear side of an Exit button.

NOTE
•Cable should be AWG22~AWG16.
•To connect the cable to Secure I/O 2, strip off approximately 5~6 mm of the end of the cable and connect them.
Power
•Do not share the power with the access controller.
•If the power is shared by other devices, it should provide 9–18V and a minimum of 500 mA.
•When using a power adapter, it should have IEC/EN 60950-1 certification.
RS-485
•RS-485 should be twisted pair, and maximum length is 1.2 km.
•Connect a termination resistor (120Ω) to both ends of a RS-485 daisy chain connection. It should be installed at both
ends of the daisy chain. If it is installed in the middle of the chain, the performance in communicating will deteriorate
because it reduces the signal level.

Fail Safe Lock
•To use fail safe lock, connect NC terminal as shown below. Normally, there is a current flowing through the relay and
the door is opened when the relay is activated by blocking current flow. The door will also be opened when there is a
blackout or power failure caused by external conditions.
NOTE
•When deadbolt or door strike is installed, the diode included with the product should be connected at both ends of the
power input as shown in the figure. Place the diode carefully in the correct direction. The cathode (stripe mark) should be
connected to the (+) of the power.
Fail Secure Lock
•To use fail secure lock, connect NO terminal as shown below. Normally, there is no current flowing through the relay
and the door is opened when the relay is activated by a current flows. The door is locked when there is a blackout or
power failure caused by external conditions.
NOTE
•When deadbolt or door strike is installed, the diode included with the product should be connected at both ends of the
power input as shown in the figure. Place the diode carefully in the correct direction. The cathode (stripe mark) should be
connected to the (+) of the power.
