Six WaySix Way

Testing and Firing continuedOverview Testing and Firing
The six way is one of the latest additions to 'Le Maitre's' range of pyrotechnic
devices, and as such represents the very latest in safety and technology
Unit Specification
Detonating MethodHigh-energy 'low voltage', time slice capacitive
discharge, with lock out.
Channel Switching Mechanical individual switching with '0', '1' (OFF/
ON) status indicators.
Test Facility Test status LED - <20mA test current.
Isolation Key switch disconnects detonator energy source.
Output Pyroflash 3 pin sockets, Prostage II quick connects.
Cabling The use of 0.5mm cable is specified for the six way
system. Cable lengths of up to 100 Metres per
channel are supported, or any combination of lengths
up to this limit.
Firing Capabilities The six way can detonate all six channels with up to
eight effects on each channel simultaneously (48
effects), or up to sixteen effects if only one channel is
to be fired. The channel and socket marked 'Air
Interface' is a dedicated channel used to fire Le
Maitre 'Air Cannons' via the 'Air Cannon Interface'
available as an optional extra. The firing pulse from
the six way is used to pulse the 'Air Cannon
Interface', which in turn detonates the 'Air Cannon'.
Supply Power 18V d.c. (2 x 9V PP3 batteries supplied) for mains
free operation. optional power supply.
The use of non 'Le Maitre'power supplies will
invalidate the warranty.
In accordance with safety regulations, the testing of pyrotechnic effects
should be viewed as a possible detonation. Therefore all clearance and
safety zoning is applicable at such times.
All channels should be up in the off position, i.e. '0' position.
With the unit in the unarmed position and the key removed from the key
switch.
By selecting channels, one by one, and pressing the test button, each effect
connected within the system can be checked for a correct circuit loop, and
this will be verified by the illumination of the channel test LED.
All wiring should be checked before use. See Checking Wiring & Pod
Section.
Any suspect device should only be removed from the system after the six
way unit has been disarmed. (Suspect devices are very rare and therefore
wiring should be checked initially).
Should it be thought that a suspect effect is present, remove it from the
system as described, store it in the original packing, and return it safely to
the source of supply.
When all effects and system wiring has been verified as correct, the six
way should be securely disarmed.
Detonating any sequence is an identical operation to testing, except that
the FIRE button will be used to perform effect ignition. All channels
should be returned to their OFF position after firing to prevent possible
corruption of the next detonation. With the unit armed via the key switch,
the test facility will work as before, but the test button will not be
required to be pushed for the test led to illuminate.
The FIRE button must be released after ignitions, to enable further
selections to be fired.
Safety is of the utmost importance in all aspects of pyrotechnic
displays and is above all else. If in doubt - DON'T.
All persons involved within any pyrotechnic display should be
aware of all safety zones.
At no time should any effect be loaded into a cabled system,
without having first removed the Arming Key, isolating the
output.
Checking Wiring & Pods
Before any cable or Pod is used in a display situation, several checks
should be made to ensure that these devices are in good working
condition Although the pressures of live performances can give rise to
the need of haste, it must always be remembered that the Pyro-Effects
Engineer will be ultimately responsible for any errors that may occur,
no matter who made them.
A thorough visual check of cables/connectors for signs of physical
damage in the form of cuts, over twisting, exposed cores, missing
securing screws etc, is the first check that can be performed.
Any faulty cabling should be discarded or repaired.
It would be wise to check the security of all connector wiring lock
screws, on a regular basis, to ensure that vibration in transit/stage
conditions, has not caused any loosening. At the same time, the cable
clamping may be inspected to ensure that the cable has not been
subjected to overstress.
A visual inspection of Pods will identify any visual damage to the Pod
case, sockets or cable connector. The cable connector sockets should be
checked for over opened terminals, which could result from excessive force,
and lead to open circuits. If they are damaged, these terminals can be
closed to their correct shape with the aid of narrow nosed pliers. Any
damaged Pod should be referred for service.
After a visual check has been performed, the six way maybe used to check
wiring integrity, Pod cartridge sockets for electrical performance.
Connect all cabling and Pods to the six way, with the Pods in close
proximity to the six way.
With all Pods empty, perform the individual Channel/Effect test
procedure. At no stage should the Channel test LED give an indication. If
the Channel Test LED does come on, then a short circuit in the cable or
Pod exists. Disconnect the Pod attached to this particular channel cable
and re-test. If the LED still remains on, then the cable is faulty, if not, then
the Pod is at fault. Either way, the faulty item should be referred for
service.
Where multiple effects are to be fired, all wiring and connections should
be checked before use.

Note that although mains type cable is used the applied voltage
is below 20 volts.
Make sure that all terminals are tight. Ensure that there are no
loose wire strands. Cable clamp should fit over outside sleeve.
A regular check should be made to verify the working
condition of all pyrotechnic cables.
