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 D9412GV2, up to
128 OctoRelay outputs (relay numbers 1 to 128) can be
added to the system using 16 OctoRelays. D7412GV2
allows up to 64 relay outputs. Review Section 6.0 Power
Outputs on page 25 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 (D9412GV2 only),
Terminal 26 on the D9412GV2. Refer to Figure 20 on
this page and Figure 21 on page 49.
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 D9412GV2/D7412GV2
Program Entry Guide (P/N: F01U003635) 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.
