Basic ADA Wiring

Wiring an ADA (Americans with Disability Act) automatic door operator into a PDK system can come in many forms, depending on the configuration of the operator itself.

In the most basic of forms, an ADA operator can be wired to function simply as a Request to Exit Device. This is done when access control is not needed to control who comes in the door or the ADA operator button/paddle only needs to be placed for egress.

In this situation, the ADA does not have any direct control over the maglock on the door, relying on the PDK system to activate/deactivate the maglock. 

To set this up, you will need two (2) open relays on the PDK controller(s), one for the maglock and the other to trigger the ADA operator.

On the first port, connect the reader, maglock, DPS, and/or normal Rex hardware as usual. 

On the second port, you will need to wire the ADA sensor/paddle as a rex input (- and B input). Then wire the trigger inputs on the ADA operator to the second relay as a dry contact (C and NO or NC, no jumper).

Once the ADA operator and sensor/paddle has been wired to the controller, you will need to set up a series of System Event Rules to do the following:

1. Create a REX rule with the source being the port 2 REX and the target being the port 1 relay.
2. Create a second System Event Rule to process a Delayed Open action with a delay of one second with the source being the port 2 REX and the target being the Port 2 relay
3. Create a third System Event Rule to process a Delayed Close action with a delay of two seconds with the source being the port 2 REX and the target being the Port 2 relay.
