10.0 Off-Board Relays
10.1 D8129 OctoRelay
Use the D8129 OctoRelay to add relay outputs to the
system in groups of eight. On the D9412GV3, up to
128 OctoRelay outputs (relay numbers 1 to 128) can
be added to the system using 16 OctoRelays.
D7412GV3 allows up to 64 relay outputs. Review
Section 6.0 Power Outputs on page 27 to ensure that
enough power is provided for the OctoRelays and
other powered devices that are 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 (D9412GV3 only),
Terminal 26 on the D9412GV3. Refer to Figure 23 on
this page and Figure 24 on page 53.
Alarm output, auxiliary relay, sensor reset, arming
status, point status, alarm memory, or remote
functions can be assigned to the OctoRelay outputs
individually. Refer to Relay Parameters in the
D9412GV3/D7412GV3 Program Entry Guide
(P/N: F01U143071) for programming details.
D8129 Restricted for Fire Systems: D8129 relay
outputs are not supervised and cannot be used in fire
or combined fire and burglary installations for primary
indicating devices.
