System Overview Addressable Modules
20 NFS-640 Installation Manual P/N 51332:B1 12/01/2003
with built-in rotary switches with the ability to select up to 159 addresses. An LED will blink on a
monitor module to indicate communication between the module and the control panel.
Note: For a list of approved notification and initiating devices, refer to the Device Compatibility
Document.
Monitor Modules - FMM-1, FZM-1 & FDM-1
. Addressable monitor modules for monitoring
conventional initiating devices. The FMM-1 is used for normally open contact alarm initiating
devices, such as manual pull stations, four-wire smoke detectors, heat detectors, waterflow, and
supervisory devices. Use the FZM-1 for interface to two-wire smoke detectors in addition to
normally open contacts. The FDM-1 provides two independent 2-wire Initiating Device Circuits
(IDCs) at two separate, consecutive addresses. Wire supervised IDCs as NFPA Style B (Class B) or
Style D (Class A) circuits. The modules come with a thermoplastic cover for mounting to a 4-inch
(10.16 cm) square mounting box.
Monitor Module - FMM-101. An addressable module that is functionally similar to the FMM-1
Monitor Module—but offered in a smaller package for mounting directly in the electrical box of
the device being monitored. (Class B input circuit only.)
Control Module, NAC - FCM-1. Addressable Control Module used as Notification Appliance
Circuits (NACs) to power and supervise compatible, UL-listed notification appliances. Wired
supervised NACs as NFPA Style Y (Class B) or Style Z (Class A). The modules come with a
thermoplastic cover for mounting to a 4-inch (10.16 cm) square mounting box.
Control Module, Relay - FRM-1. Similar to the FCM-1 except used as a Form-C control relay
module.
Fault Isolator Module - ISO-X. This module is not addressable, but listed here due to its use in
an SLC. Protects the system against wire-to-wire short circuits on the SLC. It should be placed
between groups of sensors in a Style 6 or Style 7 SLC to isolate short- and open-circuit problems
and protect the rest of the loop so it can continue to operate normally.
Pull Station - NBG-12LX. An addressable manual pull station with key-lock reset feature. The
addressable module is housed within the pull station.
Transponder - XP5-M. Supervises five Class-B addressable Initiating Device Circuits each with
a maximum loop resistance of 1,200 ohms. These circuits monitor normally open contact initiating
devises (manual pull stations, heat detectors, four-wire smoke detectors, security contacts, etc.).
One XP5-M occupies five consecutive addresses on the signaling line circuit (SLC). Each circuit
has one red LED status indicator that blinks when it is not active, and produces a steady glow when
active. For more information see the XP5 Series Transponder Manual.
Transponder - XP5-C. Each of the five circuits of the XP5-C can act as a notification appliance/
speaker/telephone circuit (Class B only) or a Form-C relay. A push-button switch changes the
circuit to a Form-C relay. One XP5-C occupies five consecutive addresses on the SLC. Each circuit
has one green LED status indicator that blinks when it is not active, and produces a steady glow
when active. For more information see the XP5 Series Transponder Manual.
Quad Intelligent Audio Transponder - XPIQ. The XPIQ is an integrated audio amplification
and distribution subsystem that can direct up to four low-level audio signals through four audio
amplifiers to integrated, continuously supervised speaker circuits. An on-board power supply
charges and supervises battery backup.
Multi-Input/Output Modules - XP6-C, XP6-R, XP10-M, XP6-MA. FlashScan capable multi-
input/output modules are available for use on the SLC loop. All are FlashScan capable.
• XP6-C controls six NAC or speaker/telephone circuits. Applications are equivalent to those
for XP5-C set as a notification appliance/speaker/telephone circuit.
• XP6-R controls six Form-C relays. Applications are equivalent to those for XP5-C set as a
Form-C relay.
• XP10-M supervises ten Class-B addressable Initiating Device Circuits (IDC) which monitor
normally open contact initiating devices. Applications are equivalent to those for XP5-M.
