Adobe Acrobat PDF. The Sigma 2 range consists of a series of
conventional fire alarm control panels designed in
accordance with European standards EN54-2 and
EN54-4 Fire Detection and Fire Alarm systems -
Control and Indicating Equipment.
The range consists of 2, 4 and 8 zone control panels. All control panels are available in two versions:
Sigma K11 range in which detectors and call points are wired on separate circuits to sounders (two sounder circuits are provided).
Sigma T11 range in which detectors, call points and sounders are wired to the same pair of cables. Commonly referred to as a two-wire system.
Wiring sounders to the detection circuits eliminates the need to install sounder circuit cables and also offers the ability to provide zoned or two stage sounder operation.
All control panels have an integral, mains powered battery charger and power supply designed in accordance with the requirements of EN54-4.
