ADA Relay
An external ADA Relay can be controlled by an output of the use of the RDR2
module, firmware version PS-201E or later, or an S300-DIN module. The activation
can be delayed without the use of external additional hardware (unlike when using
SIO8 modules). The delay is necessary to avoid operating a door-opening device
before the door is fully unlocked. For detailed information on ADA Relay Time and
ADA Relay Delay parameters see page 4-28.
The ADA relay can be wired to the green light or the shunt connector of th
e RDR2.
The ADA Relay Connector should then be set to “Green” or “Shunt,” respectively.
The “None” option disables the ADA relay. For wiring details, see “Shunt Relay
Driver Wiring” on page 3-37.
When ADA Relay Connector is set to “Sh
unt”,
the shunt connector no longer
indicates the shunt time, but the ADA Relay activation.
