FireStarter - launch of smoke, comets, fountains and rockets by R/C models
The device "FireStarter" is developed for remote control of electric igniters. Up to six electric igniters can be connected to the device. For connecting the device, one of free channels of a standard receiver of the on-board R/C system shall be used. Igniters can be activated both by a choice and successively. The device issues a high level reliability and safety required on working with pyrotechnics.
The functions:
• Choosing of one among six igniters upon a prior activation
• Bright indicator of the mode of readiness for starting
• Indicators of connection for each igniter
• The indicator of the chosen igniter
• Immediate activation of the chosen igniter after a signal from the operator
The technical data
The feeding voltage from the receiver – 4.5-5.5V
The feeding voltage from the battery – 3.6-20V
Load current – <10A
Consumption current – 50 mA
Temperature range – -40...+85C
Sizes – 52x22x15 mm
Weight (the conductors included) – 20 g
The ensured safety:
• Protection against activation on appearance of RF noise
• Protection against activation on appearance of interference in the power supply lines
• Protection against activation on hanging-up or blow-out of the own microprocessor
• Protection against an unintentional switching-on from the control panel (a prior activation is required)
• Automatic disconnection when the load current exceeds 10A (protection against short-circuiting)
• In the waiting mode, both poles of power supply are disconnected from the igniters.
Connection of the device
1. Connect the device to a free channel of the on-board receiver controlled by a switch or a button on your control panel.
2. Connect the power supply cables to the on-board battery according to the scheme. You may use the main battery or an individual battery. The recommended type of an individual light battery: two sections of Li-po accumulators with the summed voltage of 7.4V, capacity 900 mA/h, current 15C. Power supply from the battery will be used on an activation of an igniter only. Observe the polarity!
3. Fix the device on the body in an accessible point. For fixing, a double-side scotch and a hoop should be used.
4. Fix the external indicator.
5. For checking up operation of the device, the igniters may be replaced by lamps with the voltage exceeding the voltage of the battery. Or by nothing.
6. Switch-on the transmitter
7. For the chosen channel, set two replaceable positions +100% and -100% (in some transmitters – 0% and 100%, where the neutral value is 50%, not 0%). If a control stick is used instead of a switch, switching will take place in the neutral position.
8. Switch-on the on-board devices.
9. The red indicators of igniters should flash in turn. If all red indicators are lighting, invert the control channel of the transmitter. If the red indicators still are lighting permanently or the device does not switch on, disconnect the on-board power supply and check up a correctness of the connection.
Control of igniters
1. The waiting mode
* the red indicators of igniters flash in turn.
2. Choosing an igniter
* After the first switchover of signal, the red indicator of the first igniter will flash.
* If you switchover the signal with the interval less of one second, it will be possible to choose the needed number of igniter.
3. Readiness for start
* After one second, the device is ready for activation of an igniter.
* Flashing red indicator on the device shows the number of the igniter to be activated on the next switchover.
* Lighting green indicators show the channels that the igniters are connected to.
* If the green indicator of a connected igniter is not lighting, this means that the igniter is burnt-out or damaged.
* The external indicator flashes for warning on a readiness for start.
4. Ignition of an igniter
* On the following switchover of the signal, the chosen igniter will be ignited.
* If the signal is switched-over for several times, the igniters will be ignited in turn.
* If no change of the signal occurs within ten seconds, the device will return to the waiting mode.
5. Safety. Any operation will be stopped, if:
* the model leaves the zone of control of radio devices
* or RF noise appears
* or the voltage of feeding of the receiver falls
* or short-circuiting of the activated igniter takes place.
* After cessation of obstacles, the device will start its operation from the waiting mode.
The safety measures
1. One may be involved in pyrotechnical works after the relevant training and certification of qualification. More detailed information is available in the local fire-prevention service.
2. Igniters should be connected and disconnected when the on-board power supply and battery are switched off.
3. On switching-on the device and transfer to the mode of readiness, the pyrotechnics should not be directed towards any humans or any combustible substances.
4. Do not approach the model, if the bright external indicator is flashing.
5. Before preparation of the pyrotechnics, prepare yourselves for fire extinguishing as well.
6. Be careful, because the pyrotechnics may cause an inflammation of the fuel leaking from the model and other combustible substances.
7. Ensure a compatibility of the environmental conditions with the safety requirements for the chosen pyrotechnics.
8. If one second was not sufficient for igniting the activated igniter, it should be switched-out and then replaced.
9. Connect the igniters in a manner that excludes short-circuiting of conductors, their contact with other electronics and their getting into the engine of the model after activation of the igniter.
The limited warranty and responsibility
A replacement of a defected device is possible during six months. If a device is damaged because of incorrect connection or includes signs of mechanical damage, it shall not be replaced. Please, observe the polarity of connection. The manufacturer assumes no liability for any damage resulted by using the device. The copyright of the manufacturer is protected by a patent.
