14. Establishing the connecting between the output and the
e-matches, quick-fastening clamps
In general the e-matches are only to be connected when the device is switched off. By this practise
there is no danger if the controller is not supervised.
As soon as an e-match is connected and during establishing the connection as well the device and the
attached pyrotechnical effects are to be treated as 'armed' and therefore handled with maximum
caution. Depending on the individual application, safety measures that are within the sole judgement
of the user are to be met before that moment.
Insert the supplied quick-fastening clamps into the sockets on the front side. These clamps are not
isolated because of the pin. In general any usage with voltages higher than 60 Volts is prohibited.
Furthermore the item may only be used together with the products of the manufacturer.
If the clamp is squeezed the mechanism opens and you can insert a solid or stranded wire and clamp
it. In case of wear and tear the quick-fastening clamps can easily be replaced. These quick-fastening
clamps are only obtainable from Galaxis Showtechnik GmbH.
Alternatively banana plugs may be used with the sockets, too.
If you want to fire more than one e-match we always recommend to connect them in series because
this circuitry provides better testing.
When you are not sure if a circuit of several e-matches can be fired reliably you should test it several
times.

15. Continuity test (OK test)

After connecting the e-matches you can easily check if the firing line has continuity.
Switch on the device. The output LED is flashing in receiving mode in green color.
If the LED is on for a long period of time the output is open (i.e. high resistance).
If the LED is on for a short period of time the output has continuity respectively the firing line has a low
resistance.
Note: The device can not distinguish between an e-match and a short circuit.

16. Firing, firing parameters and firing power

General information:
The battery voltage of approx. 3 Volts is being used to internally generate a firing voltage of 20 Volts.
A capacitor is being charged with this voltage. The maximum firing power is at your disposal after an
operation time of approx. 30 seconds.
The firing output is protected against short circuits and can not be damages by overload conditions.
No error-prone and shock-sensitive relays are being used for switching the output power. Instead solid
state transistors ensure reliable and safe operation.
The following types of e-matches are most commonly used in Europe: Type 'A' with an all fire current
of 0.8 Amperes and type 'U' with an all fire current of 1.5 amperes.
