START-GUN Sensor /Siren (optional)
The Start-Gun Sensor is a very versatile device. In this small unit we have
managed to combine three important functions related to starting timing.
1.
Starting-Pistol sensing
.
Connect the supplied microphone and attach the other end to the starting
pistol. Connect a cable from the Auxillary Start input on the timing module to
the Start-Gun Sensor. By doing this power is now connected to the sensor and
you will see a RED Led flashing. This indicates that the device is in ‘Sample”
mode and is reading the microphone input in order to store the maximum it
“hears”. So….load the starting pistol and “BANG”. Press the RED switch to
store this value.The Start-gun Sensor will now use 70% of this noise level as a
thresh-hold . This system entirely eliminates flase triggering. From this point on
, operation of your starting pistol will send a “START” signal to the timing
module.
2.
Electronic Siren Starting
Included with the Start-Gun Sensor is an electronic siren. Connect a cable
between the Auxilliary Start input on the timing module and the Start-Gun
Sensor. After connecting this device it is important to press the RED button
once to stop the red LED flashing and to reset the device for Electronic Siren
operation.
This siren connects to the same input as was used with the microphone, and is
used to generate an audible starting signal for the athlete. Pressing the RED
button will result in a loud squeal and a simultaneous start signal being sent to
the Timing module.
3.
Thumb Switch operation
By plugging the supplied double-adaptor into the Start-gun Sensor and then
connecting this into your ‘daisy chain’ of Timing Gates, the RED button can be
