The heart of the ALGE track timing system is the OPTIc Photofinish system. Multiple competitors finishing at or around the same time present problems with manual push button finish systems as it requires one operator per lane, with varying reaction times, or with a photocell finish having over-lapping competitors recorded as only one finish impulse.
The OPTIc Photofinish records all competitors on a continuous computer image time coded up to 10,000/sec.
The starter uses a starting pistol with SM8 Start Microphone attached. He can communicate with the OPTIc Photofinish operator via a Q34 Headset and SV4/SM Speech Amplifier with Start Microphone attachment. A single pair telephone wire from the starter to the OPTIc Photofinish is all that is required.
The running time during the race is displayed to the public using and ALGE GAZ4 display. The clock stops as the first competitor crosses the finish line.
The ALGE Start Judge for Athletics is an invaluable aid for the starter. If an athlete breaks the start an audible tone is heard in the starters headset, allowing him/her to stop the race.

Another low cost alternative to the OPTIc Photofinish system would be to use an ALGE S4 timer with a Tri-fold Photocell which requires all three internal photocells to be broken before generating an impulse.
You could add an ALGE Multichannel and up to 18 pushbuttons to record all other lanes (Caters for 8-10 lanes easily). All impulses are recorded in sequence along with the channel number (representing the lane) and printed immediately to the Printer P4. Data is also sent out the RS232 serial port for use with custom scoring software on your PC. The GAZ 4 Display shows the running time during the race and stops when the first competitor crosses the finish line.
