OPERATING INSTRUCTIONS:

Normal Operational Voltage: . . . 28 VDC

(Operational from 24-32 VDC)

Average Input Current: . . . . . . . . 0.45 Amps

Peak Input Current: . . . . . . . . . . . 2.5 Amps @ .25 Seconds

EQUIPMENT LIMITATIONS:

Rotorcraft for which type certificate was applied for after April 1,
1957 to August 11,1971:

The anti-collision system must produce a minimum of 100 effective
candelas in Aviation Red or White, 360° around the vertical axis, 30°
above and below the horizontal plane. A single beacon will meet this
requirement.

Rotorcraft for which type certificate was applied for after August
11, 1971 to February 5, 1976:

The anti-collision system must produce a minimum of 400 effective
candelas in Aviation Red or White, 360° around the vertical axis, 30°
above and below the horizontal plane. This beacon does not meet this
requirement.

Rotorcraft for which type certificate was applied for after February

Aviation

5, 1976:

The anti-collision system must produce a minimum of 150 effective
candelas in Aviation Red, 360° around the vertical axis, 30° above and
below the horizontal plane. A single beacon will meet this requirement.
Certain types of installations may require additional testing.

CONTINUED AIRWORTHINESS: The 70905 series LED anti-collision
light assembly is designed with 5 columns consisting of 5 LEDs each,
and 5 columns consisting of 4 LEDs each. Should any one LED or any
vertical column fail, the unit must be repaired or replaced.

NOTE: T o red uce eye strain, use an optical filter such a s dark glasses or
a blue covering dome during LED inspection.
Inspect the lens. Replace if there is any excessive scratching, pitting,
discoloration or cracking.

INSTALLATION PROCEDURES: The following information is to assist in
the installation of a Whelen LED Flashing Anti-collision Light System.

1. The installation procedure described in the following text will be
confined to a single light installation, but is identical for multiple light
installations.

2. Prepare the aircraft for means to secure the LED Flashing Anti­collision Light assembly (see reference AC 43.13-2A, Ch. 9).

3. 28 VDC (+) and (-) ground leads equipped with an appropriate
sized breaker to be supplied to the LED Flashing Anti-collision
Light Assembly System. Both leads must be connected by an
approved FAA connection. Insure that the wire leads and the
pressure venting tube are all clear of any obstructions and ty-wrap
as required. The pressure venting tube may be trimmed to
minimum length of 1” from base.

4. Install the light assembly by securing to aircraft using #6-32 x 3/8”
(maximum length) approved hardware. NOTE: Lens mounting
screws installed with 5-7 in./lbs. of torque.

The conditions and tests required for TSO approval of this article are
minimum performance standards. It is the responsibility of those
installing this article either on or within a specific type or class of aircraft
to determine that the aircraft installation conditions are within the TSO
standards. TSO articles must have separate approval for installation in
aircraft. The article may be installed only if performed under 14 CFR part
43 or the applicable airworthiness requirements.

5. All inverted (bottom) mounted units shall require waterproofing of
the unused mounting holes. An application of single-part silicone
(RTV) or equivalent applied into mounting holes is recommended
(see illustration on page 2). Inverted and/or standard mounted
units, when necessary, may require waterproofing around any open
area where water could get in. Specifically, the lens to the flasher
base assembly, and the flasher base assembly to the aircraft.
Note: It is permissible to drill a 1/8” drain hole in the center of the
lens for bottom mounting Model 7090503 (Model 7090513 lens has
the drain hole for bottom mounting).

6. Check all avionics systems for interference from this installation.

7. A flight check should be performed by a properly certified pilot.

8. Update aircraft records, complete Form 337 and obtain FAA field
approval for installation, as necessary.
