Attach wiring to terminal blocks on ALK board as shown.
Notes about Wiring:
The EI (external inhibit) option uses NO (normally open) dry access control contacts to inhibit the ALK.
Closing the access control contacts inhibits the ALK. When the access control contacts are re-opened, the ALK re-arms with no delay.
RX, LX, and EI inputs are not polarized.
