u Has eight Class B (Style B) initiating circuits
u Includes eight UL Listed EOL resistors
The D7042 and D7042B Addressable Multiplex
Eight‑input Remote Modules have eight input loops for
conventional contacts that can be used to monitor
four‑wire smoke detectors, waterflow contacts, and
supervisory sensors. The module must be wired Class
B to the multiplex bus of the D7024 or FPD‑7024 Fire
Alarm Control Panel (FACP).
Notice
The D7024 is not listed under UL864, 9th edition.
Notice
A D7024 or FPD‑7024 FACP and one D7039
Multiplex Expansion Module are required when
using the D7042 or D7042B.
Up to 30 D7042 or D7042B modules can be supported
per FACP (15 on bus A and 15 on bus B). The D7042
module comes with a plastic enclosure and can be
mounted inside or outside the FACP enclosure. The
D7042B module comes with its own red metal fire
enclosure for remote mounting.
u Convenient plastic case (D7042) or red metal fire
enclosure (D7042B) for remote mounting
u Easy to install
u Connects to multiplex bus

Wiring Considerations
Use a minimum of 18 AWG (ISO 0.75 mm2) wire for the
initiating device circuit wiring connected to the D7042
or D7042B. Wire length per loop cannot exceed 250 ft
(76 m). For multiplex wiring requirements, see the
D7039 Installation Guide.
Notice
Do not use shielded or twisted-pair cable.
