Using ACP 2-wire DC power input
Line power is supplied by an access control panel
or access control power supply. See next section
for detailed instructions.
CAUTION
Disconnect the Access Control Panel power and
batteries before wiring the Gateway to the panel.
WARNING
Because every Access Control Panel is
different, always check the panel's instruction
manual for appropriate interface wiring.

The EIA RS485 specification labels the data wires
as "A" and "B", however, many RS485 products
label their wires "+" and "-". Some products
associate the "+" signal with "A", some with "B".
Reversing polarity will not damage either RS485
device, it will just not communicate; if it does not
work, switch the connections.
• The wires from the Access Control Panel
must be a shielded twisted pair with the shield
grounded on the ACP end.
• For compliance with UL 294, product must be
used with a UL 294 Listed Access Control Panel
or unit, respectively.
• Use power supply supplied with device or a
UL294 listed supply with minimum 12VDC
330mA/24VDC 100mA.
Description
• Gateway power inputs for 12 or 24 VDC.
• Maximum current draws 12VDC 330mA/
24VDC 100mA
• Use the ACP main regulated 12 VDC power
supply or a separate UL294 Listed 12 or 24
VDC power-limited power supply.
• Power input is non polarized.
• 4-Wire or 2-Wire bi-directional RS485
communication port for interface to Access
Control Panels.
• 2-Wire installation: Both 2|4 wire jumpers
should be added.
• 4 -Wire installation: Both 2|4 wire jumpers
should be removed.
• Refer to following pages for typical wiring
diagrams.
