Off-Board Relays
D8129 OctoRelay
The D8129 OctoRelay allows you to add relay
outputs to your system in groups of eight. On the
D9412/D9112, up to 128 OctoRelay outputs
(relay numbers 1 to 128) can be added to your
system using 16 OctoRelays. The D7412/D7212
allows up to 64 relay outputs. Review the
Power
Outputs
section of this manual to be sure you
provide enough power for the OctoRelays and
other powered devices you wish to connect to
your system.
OctoRelays for relay numbers 1 - 64 connect to
ZONEX 1, terminal 28. OctoRelays for relay
numbers 65-128 connect to ZONEX 2, terminal
26 on the D9412/D9112. See Figure 17.
You can assign alarm output, auxiliary relay,
sensor reset, arming status, point status, alarm
memory, or remote functions to the OctoRelay
outputs individually. See
Relay Parameters
in the
D9000/D7000 Series Program Entry Guide
(74-
07695-000)
for programming details.
D8129 restricted for fire systems:
The D8129
relay outputs are not supervised and can not be
used in fire or combined fire/burglary installations
for primary indicating devices.
Configuring the D8129 OctoRelay
Five switches on the OctoRelay determine the
relay numbers for the eight relay outputs. Table 3
shows the switch settings.
Warning:
Relay outputs may activate while
setting the OctoRelay switches or programming
the panel. You may wish to disconnect
equipment connected to relay outputs while
performing these functions.
Relay Outputs
Each OctoRelay output provides a Form C dry
contact rated for 1.0A at 12 VDC. Normally-open,
common, and normally-closed terminals are
available for each relay output. When an
individual output is activated, there is continuity
between the normally-open and common
terminals. When the output is not activated, there
is continuity between the normally-closed and
common terminals.
Installation
Set the switches on the OctoRelay before you
install it in the enclosure. See
Configuring the
D8129 OctoRelay
. You can install the OctoRelay
in the enclosure with the panel (see Figure 2) or
in an adjacent enclosure not more than 5 feet
from the panel. Use 16 to 22 AWG wire.
Follow the procedure below to install OctoRelays
in the enclosure with the panel.
1. Align the module with one of the mounting
locations in the enclosure. See Figure 2.
2. Use the screws provided with the module to
secure it in the enclosure.
Use the D137 Mounting Bracket to install
OctoRelays in enclosures with no module
mounting locations available.
Wiring Connections
Power down the panel to connect OctoRelays as
shown in Figure 17. Note that OctoRelays for
relay numbers 1 to 64 connect to ZONEX 1,
terminal 28. OctoRelays for relay numbers 65 to
128 connect to ZONEX 2, terminal 26 on the
D9412/D9112.
Only one OctoRelay is shown wired to each
ZONEX bus in Figure 17. Wire additional
OctoRelays in parallel. Review the
Power
Outputs
section of this manual to be sure you
provide enough power for the relays.
