Wiring the Signaling Line Circuit

Wir ing the Signaling Line Circuit ing the Signaling Line Circuit ing the Signaling Line Circuit ing the Signaling Line Circuit
The MS-9200 communicates with addressable initiating, monitor and control devices through a Signaling
Line Circuit (SLC) Loop. This SLC loop can be wired to meet the requirements of NFPA Style 4 (see
Figure 2.7), Style 6 (see Figure 2.8) or Style 7 (see Figure 2.9). Surge protection for the SLC Loop may be
provided by using one of the compatible surge suppressors listed in Table G-1 of the Appendix. The SLC
Loop is allowed to leave the building only with use of an approved surge suppressor (refer to Table G-1).
Be certain to change the decade wheels on all detectors and modules from the factory '00' settings.
ISOLATOR MODULES ISOLATOR MODULES
ISOLATOR MODULES ISOLATOR MODULES ISOLATOR MODULES
Isolator Modules permit a zone of detectors and modules to be electrically 'isolated' from the remainder of
the Communications Loop, allowing critical loop components to function in the event of a short circuit on
the SLC Loop wiring (see Figures 2.7, 2.8 and 2.9). These are required to meet the requirements of NFPA
Style 7.
MONITOR MODULES MONITOR MODULES MONITOR MODULES
MONITOR MODULES MONITOR MODULES
Addressable Monitor Modules allow the control panel to monitor entire circuits of conventional normally-
open contacts, alarm initiating devices, manual pull stations, 4-wire smoke detectors, heat detectors,
waterflow, supervisory devices (see Figures 2.14 and 2.15) and conventional detectors (see Figures 2.16
and 2.17). The BG-10LX is an addressable manual pull station which contains a miniature monitor module
providing point annunciation (see Figures 2.7, 2.8 and 2.21).
CONTROL MODULES CONTROL MODULES CONTROL MODULES CONTROL MODULES CONTROL MODULES
Through addressable Control Modules, the control panel can selectively activate Notification Appliance
Circuits or Form-C output relays (see Figures 2.18 through 2.20).

Through the Communications Loop, the MS-9200 communicates with addressable ionization, photoelectric,
and photoelectric/thermal detectors (see Figure 2.22).
DEVICE CAPACITY DEVICE CAPACITY DEVICE CAPACITY DEVICE CAPACITY DEVICE CAPACITY
The capacity of each MS-9200 includes up to 99 addressable detectors, and an additional combination of
up to 99 addressable pull stations, control modules and monitor modules. In addition, the panel supports 2
Notification Appliance (Bell) Circuits.
Note: Refer to Appendix A and the installation drawings supplied with each loop device for rating and
specification information.

Notes:
1. Trouble indicates a trouble
signal will be generated at the
control panel during the abnormal
condition.
2. Alarm Capability indicates an
alarm signal can be transmitted to
the control panel during the
abnormal condition.
3. Loop operation meeting Style 7
requirements isolates entire
physical zone on the communica-
tions loop from faults that occur
within other areas of the loop.
