CAUTION
Use care when setting the rocker switches on the
controller. An incorrectly set rocker switch can result
in an obvious controller malfunction, or in some
cases the controller can appear to be functioning
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
.
1. 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
connected. 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
is
connected, the controller
performs normally, but that detector is eliminated from
the Automatic
oi
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
oi
test procedure.
See Figure 14 for an example of selection switch
setting for a system using 12 detectors in 8 zones.
2. Controller Sensitivity — Rockers 3-1 to 3-4
Rockers 3-1 to 3-4 are used to program controller
sensitivity in 8 cps increments.
3-1 closed — 8 cps
3-2 closed — 16 cps
3-3 closed — 32 cps
3-4 closed — 64 cps
The values of the closed rockers are added together.
The rockers can be set in any combination to give the
sensitivity setting selected for the application, up to 120
cps.
NOTE
If no rockers are closed, or if only rocker 3-1 is
closed, the controller responds to an 8 cps signal
from the detector.
Refer to Figure 15 for an example of a 24 cps setting.
3. Fire Logic (Voting) — Rockers 3-5 to 3-8
Rockers 3-5 to 3-8 select the voting requirements,
which can be Fire Logic A and B common (8 zones
voting) or Fire Logic A (4 zones voting) separate from
Fire Logic B (4 zones voting). When separate, Fire
Logic A consists of zones 1 to 4, and Fire Logic B
consists of zones 5 to 8. See Figure 16.
NOTE
When the outputs are set for non-latching operation,
the voting process will actuate the Fire Logic
output(s) only if the pre-selected number of voting
zones “see” fire at the same time. When the outputs
are set for latching operation, the voting process
will actuate the Fire Logic output(s) when voting
criteria have been met, even if fire is not being seen
by each voting zone at the same time.
Separate - Rocker 3-8 closed
Rocker 3-5 programs Fire Logic A (zones 1 to 4)
— when open, votes one of four zones
— when closed, votes two of four zones.
Rocker 3-6 programs Fire Logic B (zones 5 to 8)
— when open, votes one of four zones
— when closed, votes two of four zones
Fire Logic A and B Common — Rocker 3-8 open
3-5, 3-6, 3-7 open — votes one of eight zones
3-5 closed; 3-6 and 3-7 open — votes two of eight
zones
3-5 and 3-6 closed; 3-7 open — votes three of eight
zones
3-5, 3-6, 3-7 closed — votes four of eight zones
In the example illustrated in Figure 17, the setting is for 3
of 8 zones voting.
