Reference & Installation Manual
738 Ultra employ two ways of wiring ATZ connections: ATZ series connections and ATZ parallel connections. The control panel
will recognize the installed devices as shown in Figure 15. The extra zones function exactly like any other zone displaying zone
status on the keypad and sending separate alarm codes for each zone. For more information on programming the options
mentioned in the following sections, refer to see
Zone Definitions on page 25.

2.11.1 N.C. Contacts, Without EOL Resistor, ATZ Series
If your security installation does not require tamper or wire fault recognition, but you are using the ATZ feature, connect
the detection devices and program the control panel as shown in Figure 16. Do not use devices with normally open
contacts, as this will cause the system to remain in alarm. This setup will communicate the status of each device to the
control panel (see Figure 15 on page 8) and display open zones on the keypad.
