Installation
Installation
DM-20 can be mounted with bracket or support boss.
Mounting the Bracket
1With the mounting screws for the bracket, mount the bracket firmly onto the surface where DM-20 is to be installed.
•If DM-20 should be installed onto a concrete wall, make a hole with a drill, and then insert a PVC anchor into the hole before screwin
g the mounting screw.
2Attach DM-20 onto the mounted bracket.
Mounting the Support Boss
1With the mounting screws and support bosses for DM-20, mount the bracket firmly onto the surface where DM-20 is to be installed.
•If DM-20 should be installed onto a concrete wall, make a hole with a drill, and then insert a PVC anchor into the hole before screwin
g the mounting screw.

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.
•If the power is shared by Wiegand devices, it is recommended to provide 12V and 2.5 A.
RS-485
•RS-485 should be AWG24, 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.
•Up to 31 card readers or up to 7 fingerprint devices with 24 card readers can be connected with DM-20. (If Xpass set to master device,
fingerprint devices cannot be connected as slave device.)

Connections
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.
•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.
•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.

Connections
Wiegand
•If the power is shared by Wiegand devices, it is recommended to connect 12V and 2.5 A to DM-20.
•You can use 12V, Max. 1.5A for Wiegand devices. If you connect a device that needs 1.0A to WIEGAND 0, WIEGAND 1 deliver only 500mA.
