Components
on page 4 and page 5 before connecting the PIM400-485 to
an Access Control Panel.
CAUTION: Disconnect the Access Control Panel power and batteries before wiring the
PIM400-485 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. For maximum
wire lengths and cable specifications, refer to
Cable/wire specifications
on page 8.
•
For compliance with UL294 or ULC S319, product must be used with a UL 294 or
ULC S319 Listed Access Control Panel or unit, respectively.
•
Must be used with a UL294 or ULC S318/ULC S319 Listed power-limited Power Supply
capable of sourcing at least 250mA @ 12 or 24 VDC.
