D9412G/D7412G
Off-board Relays
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, up to
128 OctoRelay outputs (relay numbers 1 to 128) can be added to the system using 16 OctoRelays. The D7412G
allows up to 64 relay outputs. Review section 5.0 Power Outputs to be sure to provide enough power for the
OctoRelays and other powered devices that will be connected to the system.
OctoRelays for relay numbers 1 - 64 connect to ZONEX 1, Terminal 28. OctoRelays for relay numbers 65-128
connect to ZONEX 2 (D9412G only), Terminal 26 on the D9412G. See Figure 17a and Figure 17b .
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: The D8129 relay outputs are not supervised and can not 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 10 shows the switch
settings.
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.
9.1.2 Relay Outputs
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
NOT MORE THAN 5 FT. (1.5 M) 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 or D9002 Mounting Skirt to install OctoRelays in enclosures with no module
mounting locations available.
9.1.4 Wiring Connections
Power down the panel to connect OctoRelays as shown in Figure 17a and Figure 17b . 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 17a and Figure 17b . Wire additional OctoRelays
in parallel. Review section 5.0 Power Outputs to be sure to provide enough power for the relays.
