tioning normally, but will not produce the desired
output in response to the input conditions. (Some
of the switches are not used and should be left in
the open position.)

The rocker switches must be set

before

power is applied

to the system.

Do not plug the controller in or remove

it from the mounting rack while power is turned on.

Zone and Detector Selection — Switch
Assemblies 1-1 to 1-8, and 2-1 to 2-8

Each zone can have either one or two detectors for
a maximum of 16 detectors in 8 zones connected to
one controller. Rockers 1-1 through 1-8 are used to
enable the detectors connected to position No. 1 of
each zone. Rockers 2-1 through 2-8 enable position
No. 2 of each zone. The appropriate rocker must be
set to the “Open” position for each detector con-
nected. Care must be taken when setting these
rockers. If a rocker is set open, but no detector is
connected in the location, the controller will show a
“2” fault on the lower digital display and the detector
display will show either a “1” or “2”, depending on
which detector is not connected in the zone. The
zone display will show the incorrectly set zone. If a
rocker is set closed, but a detector

connected,

the controller performs normally, but that detector is
eliminated from the Automatic

test sequence, and

any faults that may occur in its circuit would not be
automatically identified. This condition can be found
only when performing the manual

test procedure.

See Figure 14 for an example of selection switch
setting for a system using 12 detectors in 8 zones.
