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 1K

?

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).

2.11 Fire Circuit

If your security installation requires the use of smoke detectors, define zone 3 as a

"24-hour" fire zone; please refer to section 7.5.

2.11.1 Standard Installation

Connect the smoke detectors to zone 3 as shown in figure 20. Note that a fire zone must use a 1K

?

EOL resistor. If there is a line short or if the smoke detector becomes active, whether the system is armed or disarmed, the control panel will generate an alarm (see Fire Alarm Output figure on page 30).

If the line is "open", the control panel will send a "fire loop" trouble report to the central station and trouble indicator, key [11], will appear in the keypad’s trouble display.
