Wiring a Signaling Line Circuit (SLC)

2.9.2 SLC Devices

Communication with intelligent and addressable initiating, monitor, and control devices takes place through a Signaling Line Circuit (SLC). You can wire an SLC to meet the requirements of NFPA Style 4, Style 6, or Style 7 circuits. Table 10 contains descriptions of devices connected to an SLC:

Type of Device SLC Function

Isolator Modules

(ISO-X)

Addressable

Monitor Modules

Control Modules

Allows a zone of detectors and modules to be electrically isolated from the remainder of the loop, which lets critical loop components function if a circuit fails. ISO-X modules are required for NFPA Style 7 circuits.

Allows the control panel to monitor entire circuits of conventional alarm-initiating devices, such as manual pull stations, detectors, waterflow and supervisory devices.

Allows the control panel to selectively activate Notification Appliance

Circuits (NACs).

Allows the control panel to selectively activate Form-C output relays.

Relay Modules

XP5-M

XP5-C

Allows the control panel to monitor up to five Initiating Device Circuits

(IDCs). Each XP5-M occupies five consecutive addresses on the SLC.

Allows the control panel to control a maximum of five individual notification appliance/telephone circuits or Form-C relays. Each XP5-C occupies five consecutive addresses on the SLC.

Intelligent Detectors Allows the control panel to communicate with intelligent ionization, photoelectric, and thermal detectors on the SLC.

Addressable Pull

Station

The NBG-12LX provides a manual method of creating an alarm activation.

Maximum wiring distance of an SLC:

•

Style 4.

10,000 ft. (3048 m) (12 AWG)

•

Style 6, 7.

10,000 ft. (3048 m) (12 AWG) total twisted-pair.

2.9.3 Control Panel Capacity

AFP-200 capacity includes up to 99 intelligent detectors and an additional combination of up to 99 addressable pull stations, and monitor, control and relay modules. In addition, the control panel also supports four Notification Appliance Circuits and up to

99 programmable relays.
