Outputs 1 to 6
Outputs 1 to 6 are relay contact programmable normally open
(NO) or normally closed (NC) outputs. The supply for the Door
Strike or Maglock is not to exceed:
•
30 Vdc \ 3 amp
• 30 Vac rated \ 1 amp
Outputs 7 and 8
Outputs 7 and 8 are programmable and provide:
• 12 Vdc
•
a maximum output of 700 mA each, for a combined total
output of 1 A. For example, if output 7 provides 700 mA,
then output 8 provides 300 mA.
SW2
SW2 sets the Telephone Access controller network address. Use
DIP switches 1 to 6 to set the network address. Keep DIP switches
7 and 8 at the factory set values.

RS-485
The RS-485 connection consis ts of an input and output terminal.
Connect the RS-485 output terminal to the RS-485 input terminal
of the next controller.
Connect the last controller on the network to the RS-485 input
terminal. Refer to LT-969 section 4.2.4 for end of line resistors to
be used on the first and last nodes of network. The RS-485
terminal consists of + (positive), - (negative), and S (Shield)
connections.

Ground Terminal

The Card Access system is equipped with a 16 gauge electrical
wire attached to the panel chassis Ground Terminal. Do not
disconnect this wire.
Attach the end of the supplied wire to a suitable grounding wire
16 gauge or thicker. Attach the other end to the cold water
ground.
