3.4 AVERS TRIGGER control system programming
WIRELESS ALFA TRIGGER control system do not require any programming to operate with Pojector Trigger output
(Wireless Trigger Transmitter is programmed at ALFA control unit). Each Wireless Trigger Transmitters have a unique
code, so many WIRELESS ALF TRIGGER control systems could operate in the same area without interfere. Single
Wireless Trigger transmitter can control many ALFA units if it will be programmed to each. Programming procedure
described below have to be performed when the control system is upgraded with optional remote transmitters. Optional
remote transmitters add manual control possibility. ALFA control unit react to incoming commands immediately after
command arrival. ALFA control unit can remember up to 20 wireless remote transmitters, they must be separately
programmed at the control unit memory. IR remote transmitters do not require programming.
