10.1.1 Configuring the D8129 OctoRelay
Five switches on the OctoRelay determine the
relay numbers for the eight relay outputs
(Table 17).

10.1.2 Relay Outputs
Relay outputs can activate when you
are setting the OctoRelay switches or
programming the control panel.
Disconnect equipment connected to
relay outputs when you perform these
functions.
Each OctoRelay output provides a Form C dry
contact rated for 1.0 A at 12.0 VDC. Normally-
open, common, and normally-closed terminals are
available for each relay output. When an
individual output is activated, continuity exists
between the normally-open and common
terminals. When the output is not activated,
continuity exists between the normally-closed
and common terminals.
10.1.3 Installation
Set the switches on the OctoRelay before
installing it in the enclosure. Refer to Section
10.1.1 Configuring the D8129 OctoRelay.
Install the OctoRelay in the enclosure with the
control panel (Figure 2 on page 9) or in an
adjacent enclosure that is no more than 1.5 m (5
ft.) from the control panel. Use 1.5 mm (16 AWG)
to 0.8 mm (22 AWG) wire.
To install OctoRelays in the enclosure with the
control panel:
1. Align the module with one of the mounting
locations in the enclosure (refer to Figure 2
on
page 9).
2. Using the screws provided with the module,
secure the module in the enclosure.
Use the D137 Mounting Bracket or D9002
Mounting Skirt to install OctoRelays in
enclosures with no available module
mounting locations.
10.1.4 Wiring Connections
Power down the control panel to connect
OctoRelays. Refer to Figure 21 or Figure 22 on
page 57.
OctoRelays for Relays 1 to 24 connect
to Zonex 1, Terminal 28 on the
D7212GV4 only.
OctoRelays for Relays 1 to 64 connect
to Zonex 1, Terminal 28 on the
D7412GV4 only.
OctoRelays for Relays 65 to 128
connect to Zonex 2, Terminal 26 on
the D9412GV4 only.
Only one OctoRelay is shown wired to each
Zonex bus in Figure 21 on page 57. Wire
additional OctoRelays in parallel. Review Section
6.0 Power Outputs on page 30 for information
about providing enough power for the relays.
The number of D8129 OctoRelays that can be
connected to each Zonex terminal on the
D9412GV4 control panels is limited by the
number of D8128D OctoPOPITs connected.
