KimDen KFA-88 Series User manual

Unit Type Annunciator
KFA-88 / KFA-98
■Features
• By using a wire harness with reliable connectors, wiring for these annunciators has been greatly simpli-
fied.
• Reliable connections achieved by using a fasten tab terminal #250 for alarm input/output.
•Improved energy saving by employing “unexcited type” circuits for N.O. contact alarm input without output
contact.
•An annunciator relay with such functions as output contacts and/or surge voltage protection to satisfy vari-
ous applications.
• A bulb can only be used with low voltage because the lamp and relay are in separate circuits.
• Polycarbonate resin used for the relay assures durability and heat resistance.
• LED (LE-88A) is available for KFA-88.
• KFA-88 is used for both the incandescent bulb and LED. KFE-98 is only for incandescent bulbs.
KFA-88H / KFA-88N KFA-98B
/ KFA-98N
• When used in a circuit with induced or leakage current, the LED may unintentionally light. To prevent this malfunction,
install a resistor parallel to the indicator terminal.
• When assembling the units, be careful of the following points:
– Maximum assembly number is 6 vertical windows ×10 horizontal windows.
– When connecting a 140V 5W lamp to a 110V power source, avoid continuous use over a long period of time. This
may cause the filter to melt. 2W lamps are recommended.

• LED model LE-88A can be installed to
KFA-88H and 88N.
• When using the LED model LE-88A at
115V or 117V a current controlling
resistor must be built into the unit (code
E8) so that the LED can be used at
high voltages.
Always mark E8D on the structure label
to clarify the applied voltage.
• Use 140V 5W bulbs when using a full
voltage type100/110V.

■Mounting
Cross frame
Individual Mounting
The lens shall be removed by hand from the front surface of the control panel. Insert the annunciator
relay into the square hole which was cut with the surface lens removed. Then turn two mounting screws
clockwise with a screwdriver. Screws are located on both the inner left and right sides of the unit. This
will assure firm mounting by pushing the L-shape metal fitting up front.
Assembly Mounting (For Models KFA-88H)
Alminuim cross frames shown on the right are used.
• Assemble as many cross frames as the desired
number of units by joining the wedges together. To
make individual windows, and then assemble them
into one. Assemble by first making one vertical or
horizontal row. Then continue assembling in the same
manner. In other words, if the first row is a vertical
row, the following row should also be vertical.
• Only use a plastic hammer and always hammer to
smooth the surface side. Hammering from the back
side can cause damage to the wedges.
• When mounting the assembled units to the panel
hole, the back of the bracket (surface for mounting
sockets) at the edge unit may block the way. This is
because the brackets at the end are left open. In this
case, first remove the far right or far left vertical row.
Then the integrate unit can be easily mounted. After
mounting, replace the vertical row.
Assembly Combinations
When the voltage is the same, the following combinations are possible.
AN AC BN BC AC BN BC
AMN AMC BMN BMC AMC BMN BMC
ALN ALC BLN BLC
Replacing Relay
When the relay is damaged, it should be replaced.
The lamp socket of the indicator is engaged to the hook
of the annunciator unit, and at the same time the electri-
cal connections is secured. To separate, hold the two
components as shown in the picture and carefully bend
in a horizontal direction. Do not bend the components
vertically. This may damage the hooks.

■Wiring
Individual Wiring
The fasten tab terminal #250 is located at the back of
each unit. Connect the fasten receptacle to each
terminal: fault input, alarm output, and output
contact.
Wires should be 0.75mm2when wiring alarm output
for such items as buzzers and bells.
If only one wire is used, the maximum is limited to
1.25mm2.
Wiring Units
Wire the units together by plugging Connector Cap
“B”, which is extended from the back, to Connector
Plug “A” of the adjacent unit.
The number of units that can be wired together will
depend upon the lamp current and size of wires
used. Wire size for this unit is KIV0.75mm2. Refer to
the chart on right for the number of units.
●The maximum pitch dimensions for wire connecting
harnesses are as follows:
Model KFA-88 Width 100mm Height 50mm
Model KFA-98 Width 120mm Height 60mm
If further extension is desired, the special dimen-
sion specification will be needed.
●End terminal treatments are to be done on
Connector Cap “B”. Order the necessary number of
wire harnesses with plugs (KIV0.75mm2, length 2m)
separately. Plug “A” can be used by connecting to
the sub-panel when necessary.
Wiring Examples
Note: The necessary number of fasten receptacles will be included.
