10.1 D8129 OctoRelay
Use the D8129 OctoRelay to add relay outputs to the
system in groups of eight. The D7212GV2 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 17 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 D7212GV2 Program
Entry Guide (P/N: F01U003804) 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.
10.2 Configuring the D8129 OctoRelay
Five switches on the OctoRelay determine the relay
numbers for the eight relay outputs (Table 17).
