D8129 OctoRelay

Use the D8129 OctoRelay to add relay outputs to the
system in groups of eight. The D7212GV3 allows up
to 24 relay outputs. Review Section 6.0 Power
Outputs on page 24 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 24 connect to
Zonex 1, Terminal 28. Refer to Figure 19 on this
page.
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
D7212GV3 Program Entry Guide (P/N: F01U170808)
for programming details.
