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:
Table 10 SLC Devices
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
Refer to the installation
drawings supplied with each
loop device for rating and
specification information.
AUTOPULSE IQ-301 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.

Type of Device
SLC Function
Isolator Modules
(ISO-X)
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.
Addressable
Monitor Modules
Allows the control panel to monitor entire circuits of conventional
alarm-initiating devices, such as manual pull stations, detectors,
waterflow and supervisory devices.
Control Modules
Allows the control panel to selectively activate Notification Appliance
Circuits (NACs).
Relay Modules
Allows the control panel to selectively activate Form-C output relays.
XP5-M
Allows the control panel to monitor up to five Initiating Device Circuits
(IDCs). Each XP5-M occupies five consecutive addresses on the SLC.
XP5-C
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.
