Main Reader

 - 

The main reader is mounted at the door with a 22/5 or 22/6 

wire ran to the door controller. Wire the reader to the controller as shown 
above. Be sure to check polarity and voltage prior to powering controller.

Secondary Reader

 - 

Wire the second reader to the controller as shown 

above. Be sure to check polarity and voltage prior to powering the controller.

DPS (Door Position Switch)

 

- The DPS is mounted on the door frame in the 

desired location with a 22/2 wire running from the DPS to the controller. 
Wire the DPS to the controller as shown above. When using two DPS sensors 
for double doors you will wire them in series with only two conductors 
running back to the controller for connection.

AUX Input

 

- A rule can be setup to trigger events or outputs based on this 

input trigger.

Maglock

 

- When installing a Maglock it is typical to install a REX (Request to 

Exit) at the door for free egress. Run an 18/2 wire from the Maglock to the 
Door Controller, connecting to the Maglock as shown.

REX (Request to Exit)

 - The REX is mounted in the desired location with an 

18/5 wire ran from the REX to the controller. Wire the REX to the controller 
and maglock as shown above. If reporting is not needed in the system , simply 
eliminate the green labeled wire.

Jumper

 

- Use the designated jumper(s) to energize the relay output NO and 

NC to utilize the output as a wet contact.

C

Diode

 

- The provided diode must be installed when using a strike. Install at 

the strike with the grey stripe of diode on positive and the black on negative.

NC

 

- Used for maglocks (or strikes in fail-safe configuration). Connect the 

negative (-) of the maglock or strike to NC on the door controller.

NO

 

- Used for strikes in fail-secure configuration. Connect the negative (-) of 

the strike to NO on the door controller.

Jumper

 

- Use the designated jumper(s) to energize the relay output NO and 

NC to utilize the output as a wet contact.
