ADA-11 Loop and Strike Wiring.
An example showing wiring with two ADA-11s with
a DC Powered Door Strike. The strike is wired Fail-Secure, thus power is supplied to the strike only when the
relay is activated. The ADA-10 is wired in a similar fashion but instead of wiring to terminals, wiring must be
connected to the special connector of the ADA-10.
