A.1 Correlations
Setup and configuration of an addressable system is different than a conventional system. In a conventional system, assignment of input
devices (smoke detectors, pull stations, heat detectors, etc.) to zones is accomplished through wiring. The wiring is direct from clearly
marked panel terminals to any device assigned to a particular zone. Connection of output devices (horns, bells, strobes, etc.) in a conven-
tional system is accomplished by direct wiring of the output devices to Notification Appliance Circuit terminals.
In an addressable system, a minimum of a single pair of wires (SLC communication loop) is used to connect all addressable input and
output devices. Communications between the FACP (Fire Alarm Control Panel) and all addressable devices takes place over the wire
pair which originates from the FACP. Software programming is used to configure the system as opposed to direct wiring. Zone assign-
ments are created via software means, hence the term software zones.
Setup of an NFW-100X software zone is accomplished by panel programming. Each addressable device can be assigned to a maximum
of five software zones. Each software zone, however, may have from 1 to 99 addressable input devices assigned to it and from 1 to 99
addressable output devices assigned to it.
Monitor and control modules comprise one group of 99 addresses, with each module having a unique address from 1 to 99. Detectors
comprise a separate group of 99 addresses, each detector having a unique address from 1 to 99 in its group. Be careful not to duplicate
addresses within any one group (modules and detectors). Refer to the following page for an example of zoning.
In the example on the following page:
•
Zone 01 has the following addressable devices assigned to it:
smoke detectors with addresses 01 and 02
monitor module with address 01
monitor module with address 02 and 03
control modules with addresses 05, 06, 07, 09 and 13
•
Zone 02 has the following addressable devices assigned to it:
monitor module with addresses 02 and 03
smoke detectors with addresses 03 and 04
control modules with addresses 08, 09 and 10
•
Zone 03 has the following addressable devices assigned to it:
smoke detectors with addresses 05, 06 and 07
control module with address 04
control modules with addresses 09, 11 and 12
The example points out some of the key assignment features of the NFW-100X. Addresses of detectors are not duplicated. Addresses of
monitor and control modules are not duplicated. The control module with address 09 is assigned to three software zones (providing floor
above and floor below). Be careful to properly plan the installation prior to installing any devices.
