9.0 Off-Board Relays
9.1 D8129 OctoRelay
The D8129 OctoRelay allows the addition of relay
outputs to the system in groups of eight. On the
D9412G, a maximum of 128 OctoRelay outputs (relay
numbers 1 to 128) can be added to the system using 16
OctoRelays. D7412G allows a maximum of 64 relay
outputs. Review Section 5.0 Power Outputs to ensure
enough power is provided for the OctoRelays and other
powered devices that will be connected to the system.
OctoRelays for relay numbers 1 to 64 connect to
ZONEX 1, Terminal 28. OctoRelays for relay numbers
65 to 128 connect to ZONEX 2 (D9412G only),
Terminal 26 on the D9412G. See Figure 22 and Figure 23.
Alarm output, auxiliary relay, sensor reset, arming
status, point status, alarm memory, or remote functions
can be assigned to the OctoRelay outputs individually.
See Relay Parameters in the D9412G/D7412G Program
Entry Guide for programming details.
D8129 Restricted for Fire Systems: D8129 relay
outputs are not supervised and cannot be used in fire or
combined fire/burglary installations for primary
indicating devices.
9.1.1 Configuring the D8129 OctoRelay
Five switches on the OctoRelay determine the relay
numbers for the eight relay outputs. Table 15 shows the
switch settings.
9.1.2 Relay Outputs
Relay outputs can activate while setting the
OctoRelay switches or programming the
panel. Disconnect equipment connected to
relay outputs while performing 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,
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.
9.1.3 Installation
Set the switches on the OctoRelay before installing it in
the enclosure. See Section 9.1.1 Configuring the D8129
OctoRelay.
Install the OctoRelay in the enclosure with the panel
(see Figure 2) or in an adjacent enclosure that is no more
than 1.5 m (5 ft.) from the panel. Use 1.5 mm (16 AWG)
to 0.8 mm (22 AWG) wire.
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. Using the screws provided with the module, secure
it in the enclosure.
Use the D137 Mounting Bracket or D9002
Mounting Skirt to install OctoRelays in enclosures
with no available module mounting locations.
9.1.4 Wiring Connections
Power down the panel to connect OctoRelays as shown
in Figure 22 and Figure 23. 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 D9412G.
Only one OctoRelay is shown wired to each ZONEX
bus in Figure 22 and Figure 23. Wire additional
OctoRelays in parallel. Review Section 5.0 Power Outputs
to be sure to provide enough power for the relays.
The number of D8129 OctoRelays that can be connected
to each Zonex terminal on the D9412G panels is limited
by the number of D8128D OctoPOPITs connected.
