Installing the LEDTCL97
NOTE: The light head is to be installed in a horizontal orientation
(See Figure 1 on page 9).
Before proceeding with installation, determine approximate
location of the light head and plan all wire routing.
To install the LEDTCL97, proceed as follows:
1. See Figure 1. Position one light head on the desired mounting
surface. Ensure that the light head is level-side to-side.
Using the dimensions in Figure 2 on page 10, scribe the four
mounting hole locations and a wire routing hole on the
mounting surface.
2. For the light head, drill four 1/4" (0.25") mounting holes and a
1.00" wire routing hole at the scribed locations.
3. Install the four supplied rubber rivet nuts into the 1/4"
mounting holes.
4. Complete the electrical connections in the next section.
5. Align the light heads with the previously inserted rivet nuts.
Secure the light head with the provided #6-32 S.S. screws.
Wiring the LEDTCL97
The light head has ve 12" long lead wires exiting the rear
of the housing. Ensure that all wires are properly terminated
and insulated.

To make electical connections, proceed as follows:
1. Use 18-gauge (minimum) wire, connect the 2 RED (+) lead to
the same positive power source terminal and the 2 BLACK (–)

2. Select a ash pattern as described in the next section.
3. Apply power and test the unit for proper operation.
Selecting a Flash Pattern
The light head has eight selectable ash patterns. It is
recommended that a ash pattern is selected prior to installation.
Since this device is intended to be effective at large distances, it is
recommended that the light be projected onto a surface at least 15-
feet away from the light. See Table 4 for pattern descriptions.
To select a ash pattern, proceed as follows:
1. Apply power to the light head.
2. Briey touch the GREEN program wire to the positive power
source terminal.
3. Advance to the next pattern as needed.
4. Let the desired pattern run for at least 15 seconds to store it in
memory.
5. After desired pattern is stored, cut off exposed wire strands
from green wire and securely tape wire end.

Cleaning the Lights
CRAZING/CRACKING Crazing (ne cracks) of lenses causes
reduced effectiveness of the light. Do not use cleaning agents
(which causes crazing) such as strong detergents, solvents,
or petroleum products. If crazing of the lens es does occur, the
reliability of light for emergency signaling purposes may be reduced
until the lenses are replaced.
NOTICE
CLEANING the POLYCARBONATE LENSES:To extend the life of this
device, periodic cleaning is necessary. Clean the lens with a mild,
non-abrasive, neutral-pH cleaning agent and a soft, clean cloth.
Rinse the device thoroughly to ensure that no cleaning agent residue
remains. To avoid water spots, dry the device with a soft clean cloth.
Failure to follow this precaution can cause crazing or cracking of the
lens/dome and voids the warranty claims for the light.
