Input Wiring
Each input on the R8 has an “IN”
terminal and a “GND” terminal.
•
When using a NO relay contact to activate the
input, the contact is placed across these terminals.
•
To use a DC ground or an open collector (transistor)
as an input, connect the ground/open collector
to the “IN” terminal to activate the input.
Note that the input source must be common
grounded with the R8 board’s power source.
Output Wiring
•
Each output on the R8 has “NC”, “C”,
“NO”, and “COM” terminals.
•
When set for a dry contact output, the C, NC,
and NO terminals may be used as any relay
would. C to NC will have a connection when
the red LED for the zone is not lit. C to NO will
have a connection when the red LED is lit.
NOTE:
To set the output as a dry contact, the
yellow and black jumpers for the zone must be
removed and the output diodes must be cut.
•
When set for a voltage output, the
terminal use is as follows:
›
COM –
This is the negative DC Common
for the device being powered
›
C –
This terminal always has positive voltage, regardless
of the relay state. This terminal may be used to
power auxiliary devices such as REX or readers.
›
NC –
This output has positive voltage
when the relay is NOT ACTIVE. This
terminal is used for FAIL SAFE locks
›
NO –
This output has positive voltage when the relay
is ACTIVE. This terminal is used for FAIL SECURE locks
NOTE:
Other Securitron Power Boards (not part of
AQL series) use C as a negative DC common.
Power Control Dry
Contact Output
The outputs of the R8 have built-in reverse protection
diodes. If a delay in lock release is present or if the zone is
being used as a dry contact output, the diode from that
zone may be removed from the circuit as shown below.
NOTE:
Only remove the diodes from
outputs requiring their removal
Diode Removal
The diodes on the R8 are on the top side of the board
between the output terminals and the edge of the
board. To remove the diode from the output circuit,
simply cut the exposed diode lead for the desired
output zone - leave the diode body soldered to the pcb.
