Section 1: Overview
The Dialight Flashing Red Beacon is designed for the lighting of structures that pose a risk to aerial navigation, as specified by the FAA, ICAO and Transport Canada.
The D-264 Flashing Red Beacon as shown in Figure 1, (hereafter referred to as the Beacon) is pre-wired with a power cable and operates from a nominal 24-48Vdc. The beacon consists of High Performance LED’s that provide the light output equivalent to an incandescent fixture while consuming a fraction of the electrical power. This manual provides guidance and recommendations for the installation and checkout of the beacon assembly. Please read this document in its entirety before installing the Beacon.

Section 2: Wiring and Mounting
Warning:
Remove power from all wiring and circuitry before installing or working on the Beacon.
Wiring the Beacon
The Beacon is supplied with a power cable pre-wired to the internal electronics to facilitate installation. The only connection required is 24-48Vdc power. The ground wire must be connected for proper operation and protection of the Beacon.
Terminal Wire Color
Negative DC In Black
Positive DC In White
Chassis/Ground Green
Note: For maximum immunity to high RF field strengths, such as might be experienced on some radio antenna towers, it is recommended that the power cable be shielded. The shielding should be complete and grounded at both ends. A shielded power cable could either pass through the strain relief gland on the bottom stem, after removal and cutting short of the existing cable, or directly into the hole at the bottom of the light. The cables can be joined inside the hollow stem, from underneath the light.
Mounting the Beacon
Dialight recommends the installation of one or more lightning rods near the installed Beacon. The lightning rods should extend a minimum of three feet above the height of the Beacon.
The Beacon is mounted to the tower pedestal utilizing customer supplied ½” hardware. Six mounting holes are provided on the Beacon base (Figure 2). These mounting holes will align with most tower pedestals. The Beacon should be installed level to maintain light output in accordance with FAA requirements.

Section 3: Operation and Checkout
Prior to installation, it is recommended that the unit be tested to ensure no damage was incurred during shipping. This is accomplished by applying power to the input power cable described in section 2. Visual verification of the functioning of the Beacon will indicate proper performance.
Upon completion of the Checkout, the installation may proceed.
Section 4: Beacon Theory of Operation
4.0 System Overview
The block diagram in Figure 4 shows the major components of a typical Beacon installation. The parts of the system are the LED Beacon and Controller. The LED Beacon is made up of one LED module, which lights when current passes through it. The LED Module contains its own internal power supply. The Beacon is designed for use with an external controller. This external controller provides the properly timed flashing signal and alarm interfaces.

4.1 Lightning Protection
The Beacon incorporates protection against voltage surges (as induced by nearby lightning strikes) by means of Gas Discharge Tubes (GDT’s).
Section 5: Maintenance and Troubleshooting
No regularly scheduled maintenance is required for the Beacon.
1- Dialight warranties the light output of the Beacon to meet or exceed FAA
requirements for 5 years period (See Section 8, Dialight Warranty Statement). LED Module replacement after 5 years is recommended to ensure FAA compliance.
2- General cleaning of the Dome Assembly is recommended after re-lamping with
regular glass cleaning solution, soapy water or any acrylic cleaning solutions. No other cleaning solutions are recommended. Abrasive compounds will scratch the Dome Assembly.

Step 1 WARNING: Power to the Beacon must be removed prior to servicing.
Step 2 The Dome Assembly (D264-2005) is secured to the Beacon base by three
latches. One of the latches has a locking screw that must be removed before it can be undone. Undo all three latches located on the base of the Beacon assembly. The Dome assembly lanyard is secured to the Beacon Base support bolt. The Dome may be carefully lifted off the top of the Beacon by gently pulling outward on the lanyard hole tab and letting air enter. Once released, the Dome can be removed and set aside of the tower until ready for re-installation.
Step 3 Undo the (3) knobs holding the LED module (D264-1016) to the Base
assembly. The knobs are captive and will remain in the Base Plate.
Step 4 Carefully lift the LED module enough to allow access to the cable connecting it
to the power supply unit (fixed to the base). Carefully pull the inline connector between the LED module and power supply apart to separate the two assemblies.
Figure 6 - LED module D264-1016
Step 5 Replace the LED module using the alignment pins as a guide, make sure the
LED cable is connected to the power supply, before retightening the knobs to secure the LED assembly to the base.
Step 6 Apply power to the Beacon and verify it lights correctly. Step 7 Refit the dome, CAUTION:
hold it level and securely by the lower rim. With even pressure gently lower the dome over the o-ring seal until the bottom lip of the dome is seated on the (3) cast latch pads, ensure that the lanyard tab is approximately centered between two of the latch clamp pads. Clamp all latches and refit the locking screw.
