(OWHN¶V fire alarm system principally consists of an LQWHOOLJHQW control panel (or several
panels in a network) which provides visual warnings of alarm situations in various ways
and activates the control panel’s DODUPDQGFRQWURORXWSXWVThis is done on the basis of
information about the development of smoke, heat, flames, etc., from FRPSRQHQWV on the
loops.
The system communicates with the following types of FRPSRQHQWV on the detector loops:
♦ &RQYHQWLRQDOdetectors
♦ $QDORJXHDGGUHVVDEOHdetectors
♦ $QFLOODU\DGGUHVVDEOHGHYLFHV
(e.g. addressable digital and analogue inputs on I/O units — ',2
Each of the system’s DODUPDQGFRQWURORXWSXWV — terminal blocks in the control panels
or modules and in ancillary devices — can be programmed individually and can be of the
following types:
♦ Voltage Outputs
♦ Voltage-free outputs
The control panel may be configured to activate —
based on information from ORRS FRPSRQHQWV —
every output in the system in many different ways.
Each of the panel’s outputs must be set up with the
following parameters:
♦ 7\SHRIDODUP(alarm group):
alarm bells, fire brigade remote alarm, control
outputs, faults, pre-alarms, two-detector dependency,
etc.
♦ 'HOD\HGor instant activation
♦ 0RQLWRULQJIXQFWLRQand output number
♦ &DXVH(IIHFW (activation pattern):
which ORRSFRPSRQHQWVactivate the output and
activation pattern (pulsing, continuous, etc.)

'(/7$7HFKQRORJ\ is the collective term for the (OWHN)LUH6DIHW\ fire alarm
system, which uses new, user-friendly logic for network engineering, control panel
operation and fire alarm evaluation.
The '(/7$7HFKQRORJ\ concept has the following principal features:
• Complies with EN 54, Parts 2 and 4
• Modular construction
• Decentralised or centralised
• Flexible and user friendly
• Fully scaleable
• Extensive signal processing
• Compatible with ANX95
• High noise immunity
