Sigma XT and K2.01 product comparison

The Sigma XT panel is a three zone, single area Extinguishant control panel. This product is tested and certified to BS EN12094-1 and will become the standard extinguishing control panel for small installations. This product replaces the extremely popular K2.01 Extinguishing control panel which has been in service in thousands of installations since 1994 and has become an industry standard product worldwide.

The Sigma XT retains all of the basic functions of the K2.01 but with a number of additional features and enhancements that become available with a microprocessor based product.

In order to help understand the differences between the Sigma XT and the older K2.01 product there is a product comparison brochure available for download, using the link below. This brochure gives an overview of the differences between the two products and also technical specification information for the Sigma XT.

Syncro View - Local LCD Control Panel Repeater

Syncro View repeater offers a low cost, feature rich alternative to the familiar Syncro Focus repeater panel.
The Syncro View is not a replacement for the Focus LCD repeater, but is designed to complement the Focus LCD repeater by providing additional flexibility and configuration options to the Syncro product family.

There are some fundamental differences between the Focus (and Focus+) and the Syncro View, which are as follows -

Data Connection
The Syncro View is not connected on the Syncro Network data bus. It therefore does not take any of the 64 network addresses available on the Syncro network system.
The Syncro View is connected directly to the Syncro "Additional I/O Boards Comms" terminals and up to 15 Syncro View repeaters may be linked to a single Syncro panel.

By comparison, the Focus and Focus+ repeaters will take an address on the network.

Network Card
Because the Syncro View is not connected on the network data bus, a network card is not necessary to allow the Syncro to communicate with the Syncro View repeater. Of course, if the host panel forms part of a Syncro network then the network card will be required to fulfil this requirement

Facilities provided
The Syncro View is a local panel full function repeater. The unit will display all events on the local panel to which it is connected. Whenever any button is pressed on the Syncro View, the host panel will behave as though the same button is pressed and both the main Syncro panel and Syncro View will show the same display.
In effect the Syncro View is a remote control for the host panel that it is connected to.

The Syncro panel user will have priority over any Syncro View repeater. Therefore, the View panels cannot be used to interrogate and control a Syncro panel if the controls are already being accessed at the local host panel.

Network event filtering
Because the Syncro View will report all events from the host / local panel, it is not possible to filter events from different panels on a Syncro networked system. The network event filtering is limited to the options available to the host panel.

The Syncro Focus and Focus+ panels however can be configured to respond and display only specific events from specific Syncro panels on the network.

Syncro I/O

The Syncro View is the latest product to be connected to the Syncro "Additional I/O Boards Comms" RS485 data bus.
This general purpose data bus allows the Syncro panel input and output capability to be increased to provide a powerful and flexible solution to site specific requirements. Up to 32 different cards may be connected to this data bus, of which up to 15 may be Syncro View repeaters.

In addition to the Syncro View repeater, the following cards may be connected to this data bus

S560 - 16-channel I/O
This unit provides 16 programmable channels which may be configured as either optically isolated inputs or open collector outputs. These units can provide up to 512 programmable inputs and outputs for each Syncro control panel.

Typical applications -
· Fire mimic panels (LED indication of device in fire)
· Fireman's control panels (extract switch monitoring)
· Sprinkler indication panels
· Engineering control panels (disablement of specific parts of the system)
· Disabled refuge alarm indications

S547 - 8-way relay card
This unit provides 8 programmable low voltage changeover relay contacts. 32 of these cards provides the facility to have 256 programmable relays in addition to the standard panel relays.
Rated at 30V / 1A switching, these may be used for -
· Panel interface connections
· Outputs to building management systems
· Programmable plant shutdown facility
· Zone relay contacts

S546 - 6-way sounder card
This unit provides 6 programmable monitored sounder outputs, rated at 1A sounder load per output.
These sounder outputs are fully configurable and may be used to provide up to 192 additional sounder
circuits in addition to the standard panel sounder outputs.

Typical uses -
· Zone ringing patterns
· Floor of incidence & adjacent floor evacuation patterns
· Upgrading and converting conventional detection systems

S545 - 4 way conventional detection zone module
This unit provides four conventional detection zones, two sounder outputs and a common fire and fault relay contact. These boards can allow up to 96 conventional detection zones to be connected to any single Syncro panel.

Typical uses -
· Phased conversion of conventional systems to analogue addressable systems
· Monitoring conventional detection devices in external buildings from the main Syncro system
· Monitored input for sprinkler system flow switches

There is space for one card inside the Syncro control panel. However, as RS485 data is used to connect these devices to the Syncro, they may be located up to 1200m from the control panel. Special I/O enclosures with correct fixing positions for these boards are also available with or without power supplies.
