u Use with D7024, DS9400M, or FPD-7024

Addressable FACPs

u Fits into a standard double-gang or four-inch square

back box

The D7053 Multiplex Input-output Module is a general
purpose device that monitors a normally-open (NO),
supervised contact device and provides a separately
controlled Form C relay output. The module connects
to the multiplex bus in either a Class A (Style 6) or
Class B (Style 4) configuration. All operating power for
the module is drawn from the control panel's multiplex
bus.
Rotary switches allow convenient address setting. An
on-board status LED on the module indicates normal,
alarm, and trouble conditions and is visible on the
module or on an attractive, low-profile faceplate.

Notice

The D7024 and DS9400M are not listed under
UL864, 9th edition.

Wiring

Make connections to the terminals on the rear of the
module. All terminals can accommodate up to 12 AWG
(ISO 4 mm2) wire; however, follow wiring guidelines
specified by the National Electrical Code (NFPA-70).
All wiring is power limited and supervised.

Notice

Do not use shielded wire.

Supervise the Class B input loop with the supplied
EOL resistor.
