u Programmable relay functions
u Provides eight Form C relays
u 1 A at 30 VDC relay contact rating
The D8129 Octo-relay Module is suitable for
applications requiring Form C relays to operate
auxiliary systems or to display fire system status at
remote annunciators. Building components such as
HVAC, door lock releases, and stairwell pressurization
can interface with the D8129 for complete system
control and monitoring.
Industrial, commercial, and institutional facilities are
typical installations for the D8129 module. The eight
on-board relays can be programmed to activate on
system alarm, system trouble, individual zone or point
faults, and through remote control by authorized
users.
System overview
The D8129 Octo-relay Module provides eight
programmable Form C relays. Each relay provides dry
contact switching rated for 1.0 A at 30 VDC. The relays
are accessed through on-board screw terminal
connections.
The D8129 uses information from the control panel
serial data output to activate the relays. On-board
switches are used to configure the D8129 for different
operating modes, or to specify relay output numbers.
These switches, along with control panel programming
options, determine the D8129’s response to the serial
u Slide switch configuration
u Allows remote control of relays
data. Programming within the control panel can
activate specific relays or sets of relays in response to
system conditions.
For the G Series control panels, slide switches are
configured for specific relay output numbers, which
are activated according to their programming. The
D8129 uses five slide switches with multiple setting
options to configure its mode of operation. The D8129
receives serial data from the control panel and
activates relays in response to control panel
conditions and slide switch settings. Relays can be
programmed for remote control from a panel keypad.
Functions
Output Relays
Each relay output provides a normally-open and a
normally-closed output.
Modes of Operation
A slide switch with multiple switch settings can be
used to configure the module for a specific mode of
operation for D8112 Series systems, or programming
can be used to determine relay operation for G Series
systems.

Mounting Considerations
Up to four D8129 Octo-relay Modules can be mounted
in a control panel enclosure. For additional modules,
use the D137 Mounting Bracket.
Wiring Considerations
The D8129 connects to a control panel using the
12 VDC Auxiliary output, Serial Data Output, and
common terminals. Use 1.5 mm to 0.6 mm (16 AWG to
22 AWG) wires from the module to the control panel.
