8 The Control equipment is a combined fire alarm Control Panel and extinguishing system with up to eight detection zones, and up to four Extinguishant flooding areas. Control panels have an integral, mains powered battery charger and power supply designed in accordance 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. EN54-2 Section 10: option with requirements. Delay of the actioning of fire alarm devices (sounders) so that an alarm may be verified before a premises is evacuated.

9 EN54-2 Section : (option with requirements). Fire alarm devices to enable an audible warning to be sounded throughout premises upon the detection of a fire condition or the operation of a manual call point. EN54-2 Section : (option with requirements). In addition to the requirements of EN54-2, all Control panels have voltage free relay contacts for fire and local fire which operate upon a fire condition. These are to be used for local Control and signalling. The following compulsory functions required by EN12094-1 are included: Reception and processing of at least one input triggering signal from an and an input triggering signal from manual triggering device(s) connected directly to the Transmission of the extinguishing signal upon receipt of input triggering signal(s).

10 Activation of alarm devices upon receipt of input triggering signal(s). Unambiguous indication of each condition. Transmission of the information of the incorrect ststus of components and of the fault warning condition. Transmission of the information of the released condition. In addition to the compulsory requirements of EN12094-1 the Control Panel has the following facilities: Delay of extinguishing signal of up to 60 seconds. EN12094-1 Section : (option with requirements). Signal representing the flow of extinguishing agent to indicate the released condition. EN12094-1 Section : (option with requirements).
