NX-508E TERMINAL DESCRIPTION
DATA
Connect to the control panel
DATA
terminal. This terminal is the data-signaling terminal to all the
devices on the buss.
COM
Connect to the control panel
COMMON
terminal. This terminal supplies the common side of the
power to the NX-508E board.
POS
Connect to control panel
AUX POWER +
terminal. This terminal supplies power to the NX-508E
board.
TAM
This is an optional tamper terminal. To use this feature, connect the normally closed tamper switch
between this terminal and
COM
. If this feature is not used, a jumper must be connected between
this terminal and common.
COM
Connect to the tamper terminal through a normally closed contact.
This terminal can supply up to 100 mA fused separate from the power in the control panel.
AUX
Any power drain from this terminal should be included in total current draw from the
NetworX control panel or NX-320E as applicable.
This allows an isolation of the power
between the main control and remote devices. If a short is created past the
AUX
terminal, those devices will cease to function, but the other devices, including the NX-
508E, will continue to operate. The NX-508E will report this problem to the control for
display on the keypad as an expander power trouble.
Out 1- 8
Open Collector outputs that switch to GND when activated -- capable of up to 100 mA.
NOTE
: If
device is connected to outputs, it must see the transition from 13V to GND. The enclosed resistors
must be used. Connect the resistor between AUX and the output being used.
