IntroductionThe SIGMA CP range consists of a series of conventional fire alarm control panels designed in accordancewith European standards EN54-2 and EN54-4 Fire Detection and Fire Alarm systems - Control and IndicatingEquipment.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 soundercircuits are provided).Sigma T11 range in which detectors, call points and sounders are wired to the same pair of cables. This iswhat is commonly referred to as a two-wire system.Wiring sounders to the detection circuits eliminates the need to install sounder circuit cables and also offersthe ability to provide zoned or two stage sounder operation.All control panels have an integral, mains powered battery charger and power supply designed inaccordance with the requirements of EN54-4.In addition to the requirements of EN54-2 the control panel has the following facilities:………….Test condition to allow the automatic resetting of zones in alarm for testing purposes. EN54-2Section 10 option with requirements.………….Delay of the actioning of fire alarm devices (sounders) so that an alarm may be verified before apremises is evacuated. EN54-2 Section 7.11 option with requirements.………….Fire alarm devices to enable an audible warning to be sounded throughout a premises upon thedetection of a fire condition or the operation of a manual call point. EN54-2 Section 7.8 option withrequirements.In addition to the requirements of EN54-2, all control panels have voltage free relay contacts for fire andlocal fire which operate upon fire condition. These are to be used for local control and signalling.1B2.
