Det-Tronics C7052J UV/IR Flame Detector used with R7494, R7495 Controller - Manual (Page 16)

Terminal 34 — Do not use.
Terminals 35 to 42 — Connect to the D-leads (oi
control signal) of the corre-
sponding detectors.
Terminals 43 to 50 — Connect to the B-leads (detec-
tor output) of the correspond-
ing detectors.
PROGRAMMING THE CONTROLLER
The R7495B Controller is field programmable in order to
meet the requirements of the individual installation. This
is accomplished by setting rocker switches that are
located on the left side of the controller (see Figure 20)
to either “open” or “closed.” The programming options
are listed below. A more detailed description follows.
1. Number of detectors connected to the controller (up
to eight)
2. Gate Length, Consecutive Gate Selection, and
Count Selection (system sensitivity and time delay).
3. Detector Grouping/Voting Logic
4. Latching/non-latching outputs.
The individual rocker switches are identified by num-
bers 1-1, 1-2, 1-3, etc. in this manual. The number pre-
ceding the dash indicates the number of the switch
assembly. The number following the dash identifies the
specific rocker on the switch assembly. See Figure 20.
Each rocker switch assembly contains eight separate
rocker switches. The rockers are identified by the num-
bers one through eight on one side of the assembly.
The word “open” can be seen on the opposite side.
The switch is open when depressed in the direction of
the word “open” and closed when depressed in the
direction of the numbers.
