3. Mount and wire door contacts and request-to-exit devices.
X Install 6.8K ohm end-of-line resistors at each devices. The resistor should be wired in
parallel (across) normally open devices and in series with normally closed devices. Refer
to door wiring diagrams for additional details.
X When using PIR type request-to-exit devices, be sure to read manufacturers instructions
carefully. Many of these devices need an internal jumper position changed to work prop-
erly in access control applications. Changing this jumper setting allows the units to
quickly reset after they have detected motion. Without changing the jumper, some
devices take up to 30 seconds to reset after they detect motion. Refer to manufacturer's
instruction for additional details.
X Wireless PIR devices are not recommended for use in access control systems and should
not be used as request-to-exit devices on Access Easy Controller applications.
4. Wire any output devices that are to be controlled by the controller.
X Output circuits are typically used to control alarm bells, lighting circuits, or similar equip-
ment.
X The output relays on the Access Easy Controller 8-Input/Output card board are designed
to handle 1A @ 24 VDC Resistive. If it is necessary to control larger current devices or AC
powered devices, then external interface relays must be installed.
5. Connect all field devices wiring to the 4-reader and 8-Input/Output boards in the Access
Easy Controller.
X Refer to the device wiring diagrams in this manual to identify the termination points for
the various devices.
X All controller termination land on removable terminal strips. We suggest you carefully
remove the terminal strips before landing the wires. Once all wires have been landed on
a terminal strip and verified, gently re-insert the terminal strip on the circuit card.
X If wiring directly to the terminal strips without first removing the strip from the card, use
caution that bare wires do not accidentally touch any components or foils on the circuit
boards.
X Terminate all unused door contact and request-to-exit circuits by circuits by connecting a
6.8K ohm resistor directly across the appropriate terminals. Also terminate unused input
zones on 8-Input/Output card boards.
The following pages contained door wiring diagrams for most of the common HID readers
used with the Access Easy Controller. Instructions are also provided on how to test the read-
ers.
