Multi-area addressable extinguishant control panel

Syncro XT+ – scalable, dependable protection for complex applications.

Overview

Syncro XT+ multi area addressable control panel enables extinguishing systems to use all the features and benefits of the more sophisticated detection techniques provided by addressable fire detectors.

It also includes other benefits of analogue addressable systems such as control of loop connected sounders, beacons and input/output modules.

With up to 16 zones of addressable detection over one or two loops it ensures every detector can contribute to the extinguishant release.

The Syncro XT+ has up to four extinguishing areas and two releasing outputs per area which can be controlled via simple coincidence detection or via more complex cause and effects configured by the Loop Explorer configuration programme.

Each extinguishant area has a comprehensive set of inputs and outputs and is configurable via the Loop Explorer configuration programme.

All extinguishant areas may have up to seven serially connected Sigma Si status indication and control units, or ancillary relay boards connected via a simple four-core cable.

With the addition of a Syncro network card, Syncro XT+ control panels can be networked to provide scalable extinguishing systems for all sizes of installation.

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

The Syncro XT+ has up to four extinguishing areas and two releasing outputs per area.

Addressable Detection

Utilises addressable detection to provide precise fire location information and intelligent cause-and-effect programming for reliable extinguishant release.

Multiple Status Indicators

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

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 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

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.

Docbox

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.

To further enhance the versatility of the Syncro and Taktis fire alarm system, four conventional detection circuits can be connected with up to 30 detectors per circuit.
Conventional control panels can be replaced with this simple module, and existing conventional systems can be interfaced directly to modern analogue addressable control systems and networks.

Expansion Cards 4 Way Conventional Detection Zone Module

To further enhance the versatility of the Syncro and Taktis fire alarm system, additional sounder output capability can be added using Sounder Boards.
These boards have 6 monitored sounder outputs, each of which can be individually programmed.
In addition to the sounder outputs each board has two general purpose, opto-isolated inputs and two volt-free changeover contact outputs.

Expansion Cards 6 Way Sounder Extender Board

To further enhance the versatility of the Syncro and Taktis fire alarm system, additional relay output capability can be added using Relay Boards.These boards have 8 voltage free changeover relay contacts, each of which can be individually programmed.
Up to 32 of these boards can be connected to the dedicated RS485 communications bus in the control panel, giving the capability of up to 256 additional relay outputs.

Expansion Cards 8 Way Extender Board

To add more I/O capability to the extensive options already offered by the Syncro and Taktis control panels, up to thirty-two, sixteen-channel I/O boards may be connected.The 16-channel boards may be mixed on the RS485 bus with 8-way relay boards, 6-way sounder boards, or 4-way conventional detection zone boards to provide a very flexible system of I/O to satisfy any requirement.
