16.4. Safety distances if the device is mounted above the spectators
In general it is possible to install the devices above the spectators, e.g. on elevated truss elements.
The device does not have any fall-out but we recommend a minimum safety distance to people,
animals and flame retardant materials of 2 meters above the heads of the spectators. If the devices
are used above the spectators you have to take into consideration that they can become frightened
and could possibly show panic reactions. This bears the risk of injury and death.
16.5. Reduction of the safety distances to actors
Possibly the safety distance to performers (actors, musicians, Stuntmen, artists, etc.) can be reduced
slightly if these persons have been well trained and became familiar with the flame effect. It can be
necessary to employ other safety measures such as flame retardant or inflammable costumes,
pyrotechnical barrier gel (i.e. stunt gel) for the unprotected skin, etc. The user who is in charge for the
safety will also have to take into consideration that heat is being dissipated as infrared radiation
(invisible heat radiation) and that heat is rising upwards due to the thermal lift.
17. The various inputs and their compatibility and usage,
pin assignments of connectors
17.1. Firing key input
The firing key input requires a potential-free electrical contact. Contact debouncing has been
implemented in hardware and software. The contact must be able to withstand a switching current of
at least 100 mA at a voltage of 5V DC.
This input should always be used together with a shielded cable, especially with longer cable lengths.
The firing key input of several devices must not be connected among themselves to avoid equalizing
currents caused by different potentials. Instead either galvanically isolated keys must be used or, if
several devices should be controlled by a single key a customized solution with a galvanic isolator
must be used.
A 3pin XLR socket is installed in the G-Flame for this input. The pin assignment is as follows:
Pin1 = Ground/Shield, to be connected with the shielding of the cable
Pin2 = Output with a voltage of 5V DC with internal current limiter; this pin needs to be connected with
the electrical contact of the firing key
Pin3 = Input, 0 or 5V DC, this pin needs to be connected with the electrical contact of the firing key
A connection diagram is printed on the housing of the G-Flame.
You may also use the firing keys which are offered by us as an accessory part for the PFC Advanced.
The pin assignment is identical.
If desired we will manufacture firing key according to your requirements, e.g. firing keys with long
cables or foot switches.
