Multi-area conventional extinguishant control panel

Sigma XT+ – practical, proven control for multi‑area systems.

Overview

The Sigma XT+ range combines Sigma CP conventional fire detection from two to eight zones.

With highly configurable extinguishing control modules, it provides an integrated control solution for extinguishing systems with up to four protected areas.

The fire detection section connects to the extinguishant control modules via a serial link which allows secure, bi-directional transfer of data between the two. Sigma XT+ modules may be mounted remotely in separate enclosures and connected to Sigma CP panels via this serial interface to provide central fire detection and control with distributed extinguishing systems.

Sigma XT+ modules may also be mounted separately from fire detection and control equipment and activated by addressable output modules or volt free contacts from other systems via two monitored activation inputs.

Single or Dual Extinguishing Outputs

Configured to provide a single or secondary extinguishant releasing output. Supports common or main/reserve cylinder setups, reducing downtime after activation.

Up to four extinguishant areas

Up to 8 zones of conventional detection with up to 4 extinguishant areas are available.

Multiple Status Indicators

All extinguishant areas may have up to seven serially connected Sigma SI status indication and control units or ancillary relay boards.

Comprehensive Extinguishing Inputs

Dedicated monitored inputs support release, hold, abort, pressure monitoring and door interlock functions for complete extinguishing control.

Sigma Si is a range of system status indicator units for use with Kentec Sigma XT, Sigma XT+ and Syncro XT+ extinguishant releasing control panels. The Sigma Si range of status indicators provides detailed status information for Sigma XT and Sigma XT+ extinguishant release control equipment.

Sigma SI

The Sigma XT Ancillary Board is compatible with all Sigma XT control panels which have operating software version SIGXT_11A.HEX or above.

Sigma XT Ancillary Board

The Sigma CP Sounder Board is compatible with all Sigma CP control panels which have operating software version V3.0 or above.

Sigma CP Sounder Controller Unit

The Sigma Ancillary Board is compatible with all Sigma CP and CP-R panels which have operating software version V2.0 or above.

Sigma CP Ancillary PCB

The Addressable Matrix system uses flexible, fibre optic light guides to illuminate areas on a floor plan, laid over a high-resolution grid. This unique system dispenses completely with wiring and enables indicators to be moved, removed or added on site without the need for any wiring. Ideal for buildings such as hospitals where the building layout may evolve over a period. As the building changes, so too can the Addressable Matrix, with very little cost or disruption.

Addressable Matrix

Addressable Ident panels provide a compact and attractive display for up to 24 indications from a Syncro AS or Taktis fire control panel. As with all inputs and outputs on the Syncro AS and Taktis Fire system, each indicator is fully programmable to indicate a variety of events as well as being fully programmable via cause and effects to operate in response to logically connected inputs.

Addressable Ident

The K13480M10 Main/ Reserve switch provides a convenient and secure means to operate a switch to reserve extinguishing system agent where such provision is made as a back up to the main agent. The “901” key is common to many fire detection and protection control panels and is removable in either position. The robust enclosure allows for either surface mounting or mounting to a single gang flush box.

Sigma XT Main/Reserve Duty Extinguishant Keyswitch Unit

The K13520M10 Extract unit provides a convenient and secure means to operate extract fan plant assosciated with the fire protection extinguishing system. The “901” key is common to many fire detection and protection control panels and is retained in the operated position. The robust enclosure allows for either surface mounting or flush with optional collar.

Sigma XT Extinguishant Extract Key Switch

Sigma Si Hold off units are available with red or green actuators (BS 7273-1 recommends white with red button) and are mounted in a single gang, surface mounting enclosure. For flush mounting, the enclosure may be discarded, and the unit mounted to a standard UK single gang electrical back box.

Sigma XT Extinguishant Hold Off Units

The K13470M10 Abort unit provides a highly visible point to enable an immediate abort of a fire protection extinguishant release. The large red, domed pushbutton latches when pressed and requires a twist action to release. The robust enclosure allows for either surface mounting or mounting to a single gang flush box.

Sigma XT Extinguishant Abort Button

Easy to fit and wire for additional control functions or to expand the capability of existing relay outputs, these simple boards contains either one or four 24V DC relays, which can be used for any extra-low voltage switching applications.

Relay Boards

A range of indicator units with either red or yellow indicators to provide an audible and visual status of alarms, isolation’s or other functions.
These units are available with a keyswitch to silence the internal buzzer or a keyswitch to illuminate the indicator and buzzer. A volt-free contact is provided when the keyswitch is operated for ancillary control functions.

Plant Isolate/Audio Visual

Remote Indicator Units provide an extension for LED indicators on hidden detection devices to allow their status to be observed without having to expose the detection device itself.
All units have dual, bright LED indicators with a wide viewing angle that flash alternately to attract attention, and are available mounted to square or round metal plates for fitting to standard electrical back boxes.

Remote Indicator Unit

Designed to provide a convenient method of storing system test records, manuals, configuration files, keys and other documents or access arrangements for fire alarm and protection systems, the Sigma DocBox is finished and constructed in a similar manner to Sigma and Syncro AS fire alarm control equipment.
