connection point
Connect to the control panel Data terminal. This terminal is the data-signalling terminal to
all the devices on the bus.
Connect to the control panel COMMON terminal. This terminal supplies the common side of
he power to the NX-507E board.
Connect to control panel AUX POWER + terminal. This terminal supplies power to the NX-
507E board.
This terminal can supply up to 100 mA fused separate from the power in the control panel.
Note: Any power drain from this terminal should be included in total current draw from the
NetworX control panel or NX-320-I power supply 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-507E, will continue to operate. The NX-507E will report this
problem to the control for display on the keypad as an expander power trouble.
Connect to the tamper terminal through a normally closed contact.
This is an option 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 (or put DIP 4 to ON).
NC Normally closed dry contact rated 1 A at 30 V.
COM Common dry contact rated 1 A at 30 V.
NO Normally open dry contact rated 1 A at 30 V.
Same as relay 7 shown above.
Open collector outputs that switch to ground when activated, max. 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.
Only one required per system.
Note: X-10 plug is not to be used in an EN certified installation.
