Installation manual

Esprit 748+ 9
2.10.1 N.C. Contacts, Without EOL Resistor
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 17. 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 16),
displaying open zones on the keypad.
2.10.2 N.C. Contacts, Without EOL Resistor, With
Tamper Recognition
If your security installation requires tamper recognition and
you are using the ATZ feature, connect the detection
devices and program the control panel as shown in Figure
18. Do not use devices with normally open contacts, as this
will cause the zone to remain open. This setup will
communicate the status of each zone to the control panel
(see Figure 16), displaying open zones on the keypad. The
control panel will also communicate any detected tampers
(cuts) on the system as per Tamper/Wire Fault Recognition
Options (see section 10.7).
2.10.3 N.C. Contacts, With EOL Resistor, With Tamper &
Wire Fault Recognition (UL)
If your system requires tamper (cut) and wire fault (short)
recognition, connect two detection devices to one input
terminal with a 1KW end of line (EOL) resistor and program
the control panel as shown in Figure 19. Do not use devices
with normally open contacts, this will cause the zone to
remain open. This setup will communicate the status of each
zone to the control panel (see Figure 16), displaying open
zones on the keypad. Any tampers (cuts) and/or wire fault
(shorts) detected on the system are communicated as per
Tamper/Wire Fault Recognition Options (see section 10.7).
