FTS 812(L) USER MANUAL
Flash Technology, LLC Revision 1 – 2/10/2022 6
SECTION 1 – OVERVIEW
FTS 812(L) SYSTEM
An FTS 812(L) Approach Lighting System consists of two LED-based lighting units. One lighting unit is composed of
an FH 800(L) flash head and PC 800(L) power converter co-mounted together and a separate FH 800(L) mounted
remotely and attached to the PC 800(L) enclosure.
The FH 800(L) flash head directs the beam 25 degrees horizontally and 15 degrees vertically. The flash head is
attached to two-inch EMT pipe by a bracket that has provisions for horizontal and vertical aiming and locking.
APPLICATIONS
In ALS applications, the lights are aligned with the center line of the runway and flash sequentially toward the
landing threshold.
An ALS installation may have from 3 to 21 (or more) sequentially flashing lights.
A REIL (Runway End Identifier Lights) system consists of only two lights that are located on each side of the runway
at the landing threshold. The REIL lights flash simultaneously.
The lights can be used in a combined ALS and REIL configuration with the REIL lights flashing after the last
centerline light has flashed.

1.2 OPERATION
The FTS 812(L) system uses an internal controller, which is combined with the power converter.
The power converter has internal timing circuitry to fix the instant at which it flashes. This signal also contains
encoded flash intensity information. A control line, which enables sequential flashing, interconnects the lights.

2.2 WARNING
Read the Personal Hazard Warning (page 3) now. Remove power from all wiring and circuitry before installing or
performing work on the system. It is the responsibility of the installer to comply with all applicable electrical codes.
IMPORTANT!! Ensure the correct end of the flash head cable is pulled through the underground conduit/raceway.
Failure to pull the correct end will cause installation delays and re-work. Pay attention to all warning and
installation stickers.
2.3 BASIC INSTALLATION STEPS
1. Remove the currently installed lighting system (unless new install)
2. Secure the co-mount assembly (FH & PC) and mounting hardware to mounting pipes (2 x 2” OD)
a. The previous mounts can be re-used, if in appropriate condition
b. Ensure installed assembly does not exceed 34” in height
c. Use the included bubble tool to ensure fixture is level
3. Install the incoming power and remote control wires to the terminal block in the PC
4. Secure the remote-mount assembly (FH) to single mounting pipe (1 x 2” OD)
a. The previous mounts can be re-used, if in appropriate condition
b. Ensure installed assembly does not exceed 34” in height
c. Use the included bubble tool to ensure fixture is level
5. Connect the included FH cable to the back of the remote-mount assembly
6. Use the twist connecter to secure
7. Route other end (loose cable) to the PC
a. Route via underground conduit
b. Not recommended to leave cable exposed
8. Cut the cable to an appropriate length and terminate inside the PC
9. Follow internal info card and terminal block labels
10. Aim each LED FH using the external vertical and horizontal leveling guides
11. Tighten hardware to lock assembly into place
12. Power the system ON and verify operation (local & remote) and user settings
13. After all steps are completed successfully, the installation is finished

FTS 812(L) USER MANUAL
Flash Technology, LLC Revision 1 – 2/10/2022 11
2.4 INSTALL THE CO-MOUNT AND REMOTE-MOUNT UNITS
Install the co-mount and remote mount units on separate concrete pads as illustrated in Figure 2.2. Cut EMT pipe
such that the dimensions shown in Figure 2.2 are maintained. A bulls-eye level is supplied to assist in leveling the
units and is placed in a hole in the mounting brackets. Using this level as a guide, loosen the supplied 2” EMT
fittings at the top of the EMT conduit enough to allow the mounting bracket to be moved until it is level, then
tighten the fittings. Ensure that the mounting brackets are level after all fittings have been tightened.

FIGURE 2.2 –SYSTEM DIMENSIONS AND MOUNTING DETAILS (CONTINUED)
2.5 AIMING THE FH 400(L) FLASH HEADS
Both flash heads are mounted to a bracket which allows the flash head to be rotated in the horizontal and vertical
axes. Vertical aiming requires loosening of four nuts, two on each side of the mounting bracket. Once these nuts
have been loosened, the flash head can be rotated to the desired vertical angle using the scale provided. After the
angle has been set, tighten all four nuts to lock the unit in place at the desired vertical angle. Horizontal aiming
requires loosening the two nuts on the bottom of the mounting bracket. Once these nuts have been loosened, the
flash head can be rotated to the desired horizontal angle using the scale provided. After the angle has been set,
tighten both nuts to lock the unit in place at the desired horizontal angle.
2.6 WIRING THE SYSTEM POWER AND COMMUNICATIONS CONNECTIONS
The system is supplied with a 3-foot pigtail for connecting the co-mounted flash head and a separate 50-200-foot
pigtail for connecting the remote mounted flash head. This longer pigtail is intended to be cut-to-length and
terminated in the field, while the short pigtail can be used as-is. The long pigtail and remote input wires are to be
routed up inside the right side conduit of the PC 800(L) and the incoming power for the system should be routed
up the left side conduit. The short pigtail is routed down through the cable gland between the conduits and out to
the co-mounted flash head as shown in Figure 2.2. Input power connections required are power (100-240 VAC,

external ground lug of the PC 800(L) must be grounded separately.
A remote switch can be connected via the remote inputs and remote power output to enable remote switching of
the 812(L) system. This switch should accommodate switching of the 24 volt remote DC + power provided by the
PC 800(L) terminal block.

2.7 VERIFYING OPERATION
Apply power to the system and verify operation and user settings.
2.7.1 POWER UP
When powered up, the system will begin flashing. The flash heads will continue to flash as long as the system is set
to a flashing operation mode.
SECTION 3 – BEACON OPERATION
3.1 SYSTEM OVERVIEW
The system has 5 operating modes: Remote, Off, Low, Medium and High. The system operates in a mode chosen
by an external switch capable of switching 24 volts DC through the remote input connections available in the PC
800(L) enclosure. It is also possible to locally control the operating mode using the rotary knob available on the
User Interface PCB. For general operation, this knob should be set to the “Remote” position. A power supply is
located inside the PC 800(L) and powers both flash heads and the enclosure it resides in. The PC 800(L) enclosure
has an interlock switch which disconnects incoming power when the door is opened.
3.2 USER INTERFACE BOARD
The user interface board is located inside the PC 800(L) enclosure and controls the operational parameters of the
REIL system. Refer to Figure 3.2 for a graphical reference to the sections listed below.
Figure 3.2 – User Interface Board

FTS 812(L) USER MANUAL
Flash Technology, LLC Revision 1 – 2/10/2022 15
CONTROL SECTION:
•The 5 position knob controls the mode of the FTS 812(L) system.
•Set the knob to Remote to enable control of the unit to be the remote inputs.
•Set the knob to Off, Low, Med or High as desired for setup and maintenance purposes.
OPERATING MODE SECTION:
•An LED indicator lights up to show what mode the system is currently operating in.
COMM STATUS SECTION:
•An LED status indicator lights up green to show working communications status with a light
connected to the PC 800(L). FH1 corresponds to LightA, FH2 corresponds to LightB, and FH3
corresponds to LightC. The Trunk line lights up only when communications are detected for
sequenced approach systems and is not used for REIL’s
REMOTE MODE STATUS SECTION:
•An LED indicator lights up to show the mode that the system has been remotely commanded to
operate in.
ALARMS SECTION:
•An LED indicator will light up red if a fault has been detected. For a given flash head:
oIf the comm status indicator is not lit, and the alarm indicator is lit - then a communication
fault has been detected.
oIf both the comm status indicator and the alarm indicator are lit, then the fault is due to a
light failure.
LIGHT STATION SECTION:
•This section is used for sequenced approach systems only.
STANDARD CONFIGURATION SECTION:
Flash Rate section:
oPress the button to select between a flash rate of 60 flashes per minute and 120 flashes per
minute.
IR/Visible Enable section:
oPress the button to select between: IR only, Visible only and both IR and Visible light output.
Threshold Enable section:
oPress the button to select “Yes” for REIL systems. Select “No” for sequenced approach
systems.
Spacing Interval section:
oPress the button to select between 16ms, 33ms and 66ms intervals between flashes in a
