Manual Firing
Manual firing (without use of script) is also possible. Pressing and holding down cue button on armed 18R2,
causes the WSQP to fire the corresponding canister combination for the duration the button is held down
for.

DMX Operation
The WSQP can be operated through DMX-512. Five channels are required – one channel is a safety channel,
the remaining four channels each operate one firing solenoid.
Two independent addresses can be set. The first address is for the safety channel, the second address is the
first of four fire channels. The three remaining fire channels will be the three consecutive channels. See
section 5.3.5 for more details.
To arm the machine (in default arm mode), the safety channel must be set to a value between 70-90%.
This range is different to the regular SQP, but is considered a safer method of arming as it is a ‘deliberate’
range and not a value which can easily happen during a failure condition.
For example:
Safety - Channel 12. Solenoid/flame – Channel 2. Arm the machine by setting CH12 to 70-90%. The fire
channels will be 2, 3, 4 and 5.
The order of the canister channels can be seen in Figure 2 (section 4.6).
Once the safety channel is within the range of 70-90%, the ARM flame LED will start to flash whilst the
safety timer is counting down. During this safety delay, the unit is prevented from firing. Once the timer
has elapsed, and the ARM LED goes solidly ‘on’, the unit is ready to fire.
When a solenoid/fire channel is raised above 50%, a solenoid forces a plunger into the fuel canister,
opening the canister valve and allowing the pressurised fuel to escape via the output nozzle located at the
base of the flue.
It is recommended that the fire channel is activated with the ‘flash’ buttons present on most DMX
controllers. This allows for greater control over the effect produced. A brief activation of the channel (0.5 –
1s) will produce a short-duration fireball effect. A longer activation will produce a tall ‘tongue’ of flame.
Any number of fire channels can be activated simultaneously resulting in firing from the corresponding
canisters. Firing multiple canisters at the same time will result in a taller, broader flame. Please see the
maximum flame heights presented at the start of this manual for more information.

Final Notes
It is recommended that operators of the Wireless SQP take some time to familiarise themselves with the
effects produced in order to achieve the best results.
It is advised each show design is tested before an event.
In case of any doubts and/or questions regarding the Wireless SQP and/or its operation please contact
Le Maitre.
Warning:
A firing solenoid should never be continuously activated for more than 30 seconds.
Keeping a solenoid powered for extended periods risks damage to the solenoid coil.
