Single Zone Input Terminal Connections. PARADOX Esprit 748 express +

Installation

Once the keypad zones have been defined you must enable "Keypad Zone Supervision" (see section 7.13 & 7.14) in the control panel. Figures 8 and 9 demonstrate typical keypad zone input installations.

Single Zone Input Terminal Connections

The system hardware recognizes the following single zone input terminal connections. For more information on programming the options mentioned below refer to ZONE DEFINITIONS in section 7.

2.9.1 N.C. Contacts, Without EOL Resistor

If your security installation does not require

Installation tamper or wire fault detection, connect the detection devices and program the control panel as shown in figure 11. This setup will communicate an open or closed zone to the control panel, displaying open zones on the keypad. Do not use devices with normally open contacts in this setup, as this will cause the control panel to remain in alarm.

2.9.2 N.O. and N.C. Contacts, With EOL Resistor (UL)

If your security installation does not require tamper or wire fault recognition but some detection devices will use normally open contacts. Connect all detection devices using a 1K

?

end of line (EOL) resistor and program the control panel as shown in figures 12 and 13. This setup will communicate an open or closed zone to the control panel, displaying open zones on the keypad.

2.9.3 N.C. Contacts, Without EOL Resistor, With Tamper Recognition

If your security installation requires tamper recognition, all detection devices must use normally closed contacts. Connect the devices and program the control panel as shown in figure 14. This setup will communicate an open or closed zone to the control panel, displaying open zones on the keypad. The control panel will also communicate any detected tampers (cuts) as per Tamper/Wire Fault

Recognition Options (see section 10.7).

2.9.4 N.C. Contacts, With EOL Resistor, With Tamper and Wire Fault

Recognition (UL)

If your security installation requires tamper

(cut) and wire fault (short) recognition, all detection devices must use normally closed contacts. Connect the devices and program the control panel as shown in figure 15. This setup will communicate an open or closed zone to the control panel, displaying open zones on the keypad.

The control panel will also communicate any detected tampers (cuts) and/or wire faults (short) as per Tamper/Wire Fault Recognition Options (see section 10.7).
