Communication with the addressable initiating, monitor, and control devices occurs through Sig-
naling Line Circuit (SLC) loops. The basic unit includes two SLC loops on the main circuit board;
two SLCs are included on each Zeta Addressable Communication Module (ZACM). Each SLC
loop can be wired to meet the requirements of the NFPA Style 4 (see Figure W-2), Style 6 (Figure
W-3), or Style 7 (Figure W-4). Refer to Section 1.4.8 for wiring specifications.
There are four basic types of devices that can reside on an SLC:
1. Isolator Modules (IMB-750) permit a group of sensors and modules to be electrically "iso-
lated" from the remainder of the SLC, allowing critical loop devices to function in the event of a
circuit fault (see Figure W1d). IMB-750s are required to meet NFPA Style 7 requirements.
2. Switch Monitor Modules (MPM-830, PMM-806) and Input/Output Modules (MIO-820) allow
the control panel to monitor entire circuits of conventional alarm initiating devices such as
manual pull stations, smoke detectors, heat detectors, waterflow and supervisory devices (see
Figure W-6). Monitor modules can also have specialty functions. Refer to Section 5 For more
information on the specialty functions
3. Smoke and Heat Sensors (ISH-550, PSH-650, TSH-450, RWAA[X], RWAR[X]) allow the
panel to monitor an environment for smoke and heat conditions indicating a fire condition.
(See Figures W-1a-e for base wiring)
4. Output and Input/Output Modules (SCM-825, MIO-820) allow the control panel to selectively
activate notification and relay outputs. (See Figures W-7, W-8)
Each loop will support up to 126 addresses for devices of any type. Isolator modules do not require
an address and are not included in the 126-device total. The basic panel will accommodate 252
total devices. The panel will support three additional Addressable Communication Modules
(ZACM) and each ZACM will support 252 total devices up to a total of 1,512 total addressable SLC
devices.

There are three types of bases that may be used with the
optical, ionization, and thermal sensors: XP95A Mounting
Base (Figure W-1a), MB-SDR-XP95 Sounder Base (Fig-
ure W-1c), and the MB-RLY-XP95 Relay Base (Figure W-
1b). The isolator base, (wiring shown in Figure W-1d), is
only used with the isolator module.
Figure W-1e displays base wiring for two duct detectors —
RWAA, RWAR.
