Overview

The NX-216E is a microprocessor-controlled 16 zone expander for the NX-10 control panels. Up to
five NX-216E expanders can be added to the NX-10 control panel with a maximum zone count of 40
zones (making total of 48 zones for the NX-10). Each expander has an optional tamper switch and
power isolator making it ideal for use in a remote location.

Terminal Description
POS Connect to the KP POS terminal of the control panel. Current draw is 30 mA.
COM Connect to the KP COM terminal of the control panel.
DATA Connect to the KP DATA terminal of the control panel.
TAM Connect as shown below. If not used, connect to a COM terminal.
AUX Can be used to power devices directly from the NX-216E. Power is coming from the control panel,
therefore the current draw of these devices must be added to the total current draw of the NX-216E. This
output is current limited to 100 mA.
Z9 Connect to one side of zone 9 loop. Connect the other side to COM terminal. Open or short causes alarm
(see wiring diagram for examples).
COM Common (-) terminal for zones 9 & 10.
Z10 Connect to one side of zone 10 loop. Connect the other side to COM terminal. Open or short causes alarm.
Z11-Z24 Connect as described for Z9 & Z10.
