- Connect a Push-to-Exit
Push-to-Exit buttons are usually put on the interior part of the door and
allows you to exit once pressed. Connecting them is a breeze and below will
provide the guide.

• GRD
: This port provides Ground to the Push-to-Exit Button. The wire that is
connected to this port is typically called the Common Wire.
• P1
: This port is the signal port to tell the board to open the corresponding
door. When connecting a simple button there is only one combination
involved which is
NO
(Normally Open). This means that the door in normally
locked until the button is pressed. With more advanced buttons you have 2
options
NO
and
NC
(Normally Closed). The
NO
operates as explained above
but
NC
will keep the door open until the button is pressed. The default is
NO. The 1 in P1 is the door number the Push-to-Exit Button corresponds to.
For example, P2 is for Door 2.
Exclusive to the 1 and 2 door access
control boards is the option to connect multiple
readers per door. This is used for attendance and
anti-passback. As shown in the figure to the left,
you could connect 2 readers to the board (one
connected to the enter side and the other to the
exit.) You would then proceed to place the Enter
reader on the exterior part of the door and the
exit reader to the interior. This means that instead
of using a Push-to-Exit button to leave you will
have to use the reader instead. Please make
sure you connect the Enter reader to the “Enter”
reader ports and the same with the Exit reader.
You can see an example of this in Section 05.6
labeled “Dual Readers”.
