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 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.

Installing OctoRelays
Set the switches on the OctoRelay before installing it in
the enclosure. Refer to Section 10.2 Configuring the
D8129 OctoRelay on page 42.
Install the OctoRelay in the enclosure with the control
panel (Figure 2 on page 8) 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 8).
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.
10.5
Wiring Connections
Power down the control panel to connect OctoRelays.
Refer to Figure 17 on page 42.
OctoRelays for Relays 1 to 24 connect to
Zonex 1, Terminal 28.
Only one OctoRelay is shown wired to each Zonex bus
in Figure 17 on page 42. Wire additional OctoRelays in
parallel. Review Section 6.0 Power Outputs on page 24
for information about providing enough power for the
relays.
