Reader Wring
The reader port supports a reader with TTL (D1/D0, Clock/Data), F/2F, or
2-wire RS-485 signaling. (Refer to the reader manufacture specifications for
cabling requirements.) In the 2-wire LED mode the buzzer output is used to
drive the second LED. Reader port configuration is set via the host software.

Door Strike Relay Wiring
Two (2) Form-C contact relays are provided for controlling door strike or
other devices. See specifications section for the relay contact ratings. Load
switching can cause abnormal contact wear and premature contact failure.
Switching of inductive loads (strike) also causes EMI (electromagnetic
interference) which may interfere with normal operation of other
equipment. To minimize premature contact failure and to increase system
reliability, a contact protection circuit must be used. The following two (2)
circuits are recommended. Locate the protection circuit as close to the load
as possible (within 12 inches [30 cm]), as the effectiveness of the circuit will
decrease if it is located far away.
Typical DC Door Strike Wiring
Diode Selection: Diode current rating: 1x strike current. Diode breakdown
voltage: 4x strike voltage. For 12 VDC or 24 VDC strike, diode 1N4002
(100V/1A) typical.
