The D7212GV4 can use up to 3 B308 Octo-output
relay modules to provide all 24 of the supported
off-board relays.
The B308 Octo-output relay modules provide a
non-contiguous support of available off-board
control panel relays to allow concurrent use of
Zonex relays. For example, off-board relay
numbers 9 and 10, 20 and 21 can only be on a
Zonex OctoRelay module. Refer to Table 25 on
page 71 for relay number to module assignments.
