MODEL HRCFA SERIES SELF-CONTAINED STROBE
ANTI-COLLISION LIGHT ASSEMBLY
HRCFA series is a self-contained CometFlash
design re-directs stray light rays into the horizontal plane to provide maximum 360º of uniform light coverage. Available in
three different lens colors, aviation Red, aviation White and split aviation Red/White and in radio-shielded configurations. FAA
approved as a direct replacement for any rotating beacon that uses a 3-3/4" (95mm) dia. mounting hole. Can be installed in
the vertical fin or the fuselage. Fuselage installation requires the A440 mounting adapter. Operates between 10 to 30 VDC.

MODEL SACF SELF-CONTAINED STROBE
ANTI-COLLISION LIGHT ASSEMBLY
SACF series self-contained CometFlash strobe anti-collision light which utilizes the same power supply & housing as
the model HRCFA. It uses an aviation White glass lens only, ideal for agricultural applications where chemicals are
used. Because the lens has no optics built-in, it produces 300 effective candlepower. It uses a 3-3/4" dia. mounting
hole. Fuselage installation requires the A440 mounting adapter. Operates between 10 to 30 VDC.

Installation
The HRCFA & SACF self-contained strobe light assemblies are interchangeable
with Rotating Beacons on any aircraft with a 3.75 inch diameter fairing or mount-
ing adapter. It is not necessary to change any of the existing wiring, or circuit
breakers. The light assembly must be properly mounted to comply with FAR Part
91.205(c-2) & (c-3). When necessary (such as fuselage installation), the Whelen
model A440 mounting adapter must be used.
Mounting
1. Remove the existing beacon.
2. Make the necessary wiring connections using the existing wiring. Positive
(+) to the WHITE wire, and Ground (-) to the BLACK wires protruding from
the light assembly. All connections must use FAA approved techniques.
Note: It is recommended to ground the unit to the buss bar or the
battery. Using the airframe as ground may produce EMI/RFI interference.
3. Remove the three (3) 6-32 x 3/8" mounting screws from the light assembly.
Do not use longer screws, damage to the unit may occur.
4. Insert light assembly into mounting location and attach using screws as
mentioned in step 3. There are two sets of mounting screw locations on the
unit for installation versatility (unit may be sealed around periphery with
RTV or equivalent).
5. If the A440 mounting adapter is used, attach light assembly to adapter

using screws as mentioned in step 3 (unit may be sealed around periphery
with RTV or equivalent).
6. If light assembly is mounted in an inverted position, drill a 1/8" diameter hole
in lens as indicated on the lens label. For the model SACF series, remove the
RTV plug from the hole in the lens.
7. When installing the light assembly in a rudder mount location, rudder balance
must be checked with reference to the aircraft's service manual. The weight
and balance should equal the original rotating beacon.
8. Check all avionics systems for interference from the installation with reference
to AC 43.13-2a, Chapter 4, paragraph 52 (b).
9. Label all switches and breakers, install pilot warning placard.
10. Update aircraft records, complete Form 337 and obtain FAA field approval for
installation, if not covered under STC eligibility list.
Flash Tube Replacement
1. When a flash tube failure occurs, remove the #6 Phillips head screw on the
clamp ring. Be careful not to lose the #6 hex nut.
2. Remove the clamp ring.
3. Lift the lens assembly & gasket off the strobe tube.
4. Lift the strobe tube and carefully unplug the connector.
5. Replace with new strobe tube assembly.
6. Attach all parts required. See parts breakdown for replacement part numbers.
