Introduction
The SIGMA XT+ range of control panels are designed in accordance with European standards EN54-2 and EN54-4
Fire Detection and Fire Alarm systems - Control and Indicating Equipment and EN12094-1 Fixed firefighting systems
- Components for gas extinguishing systems - Part 1: Requirements and test methods for electrical automatic control
and delay devices.
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. EN54-2 Section 7.11: (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 7.8: (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:
4.3.2a Reception and processing of at least one input triggering signal from an f.d.a.s and an input triggering signal
from manual triggering device(s) connected directly to the e.c.d.
4.3.2b Transmission of the extinguishing signal upon receipt of input triggering signal(s).
4.3.2c Activation of alarm devices upon receipt of input triggering signal(s).
4.2.2d Unambiguous indication of each condition.
4.2.3e Transmission of the information of the incorrect ststus of components and of the fault warning condition.
4.3.2f 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 4.17: (option with requirements).
Signal representing the flow of extinguishing agent to indicate the released condition. EN12094-1 Section 4.18:
(option with requirements).
Monitoring of the status of components by way of a low pressure switch input. EN12094-1 Section 4.19 : (option with
requirements).
Emergency hold device to enable the extinguishant delay time to be extended. EN12094-1 Section 4.20: (option with
requirements).
Control of flooding time to deactivate the releasing output after a set period of time. EN12094-1 Section 4.21: option
with requirements.
Manual only mode to disable the release of extinguishant via automatic detection devices. EN12094-1 Section 4.23:
(option with requirements).
Triggering of equipment outside the system by way of first and second stage contacts, extract fan output etc.
EN12094-1 Section 4.26: (option with requirements).
Activation of alarm devices with different signals to indicate pre- discharge and released warnings using different
sounds. EN12094-1 Section 4.30: (option with requirements).
Emergency Abort device to inhibit the extinguishing signal until the emergency abort device has been de-activated
and the panel has been reset. EN12094-1 Section 4.27: (option with requirements).
Extinguishing signals to spare cylinders. EN12094-1 section 4.25 (option with requirements)
